一.如何选择MySQL的安装方式
1>.选择安装的MySQL版本
1.首先判断是否要和公司其他已经安装好的MySQL保持版本一致； 2.如果没有上述要求，则一般会安装最新版本（截止2019年1月初，目前最新MySQL版本是8.0.13）； 3.如果不是实验新功能特性，则不要选择development release，而要安装General Available（GA）release（代表稳定版本，可在生产环境中使用）；
2>.下载正确的tar包
下载地址：https://dev.mysql.com/downloads/mysql/。
3>.如何选择MySQL的安装方式
1.程序包管理器管理yum/rpm方式安装mysql yum/rpm方式安装mysql安装极其简单，只要执行 yum -y install mysql-server即可。 yum/rpm安装方式安装MySQL应用场景： 适合对数据库要求不太高的场合，例如并发不大，公司内部，企业内部的一些应用场景。大的门户网站公司他们把源码根据企业的需求制作出rpm，搭建yum仓库，yum -y install xxx 2.源码安装mysql 此种方法适合所有的MySQL5.0.xx-5.1.xx产品系列，是最常规的编译方式。 source code，一般情况下会选择二进制安装方式，如果有特殊需求，比如修改一部源码或修改MySQL深层次的配置，则会选择源码方式。 3.采用cmake方式编译安装MySQL 由于MySQL5.5-5.6.xx产品系列特殊性，所以编译方式也和早期的产品安装方式不同，采用cmake或gmake方式编译安装。 4.采用二进制格式的程序包(展开至特定路径，并经过简单配置后即可使用)方式免编译安装MySQL 二进制安装包的方式（RPM包，ZIP，Tar等),这种方法和yum /rpm 包安装方式类似，适合各类MySQL产品系列，不需要复杂的编译设置及编译时间的等待，直接解压下载的软件包，初始化即可完成MySQL的安装启动 如何选择MySQL的安装方式 yum/rpm方式安装MySQL适合于对数据库要求不太高的场合，例如开发不大，公司内部，企业内部的一些应用场景。 二进制免安装比较简单方便，适合5.0-5.1和5.5-5.6系列，是很多DBA的选择，普通Linux运维人员多采用编译的方式，5.0-5.1系列就是常规编译方式，5.5-5.6系列就是cmake编译方式。 推荐：MySQL5.5及以上的版本；安装方式机器数量少的话，使用cmake编译方式；数量多的话采用二进制免安装。 博主推荐阅读: 使用二进制安装包的方式单机部署MySQL8.0.13(https://www.cnblogs.com/yinzhengjie/p/10201038.html) 使用yum源的方式单机部署MySQL8.0.13(https://www.cnblogs.com/yinzhengjie/p/10212038.html)
二.基于yum方式安装MySQL
在CentOS 6.x版本中的确存在MySQL的安装包，但CentOS 7.x之后版本，MySQL的yum源被踢出，取而代之的是MariaDB源。 因此，我们想要在CentOS 7.x版本上安装MySQL，就需要查看MySQl官网提供的yum资源（https://dev.mysql.com/downloads/repo/yum/） 博主推荐阅读: 使用yum源的方式单机部署MySQL8.0.13(https://www.cnblogs.com/yinzhengjie/p/10212038.html)

All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Usage: mysql [OPTIONS] [database] -?, --help Display this help and exit. -I, --help Synonym for -? --auto-rehash Enable automatic rehashing. One doesn't need to use 'rehash' to get table and field completion, but startup and reconnecting may take a longer time. Disable with --disable-auto-rehash. (Defaults to on; use --skip-auto-rehash to disable.) -A, --no-auto-rehash No automatic rehashing. One has to use 'rehash' to get table and field completion. This gives a quicker start of mysql and disables rehashing on reconnect. --auto-vertical-output Automatically switch to vertical output mode if the result is wider than the terminal width. -B, --batch Don't use history file. Disable interactive behavior. (Enables --silent.) --bind-address=name IP address to bind to. --binary-as-hex Print binary data as hex --character-sets-dir=name Directory for character set files. --column-type-info Display column type information. -c, --comments Preserve comments. Send comments to the server. The default is --skip-comments (discard comments), enable with --comments. -C, --compress Use compression in server/client protocol. -#, --debug[=#] This is a non-debug version. Catch this and exit. --debug-check This is a non-debug version. Catch this and exit. -T, --debug-info This is a non-debug version. Catch this and exit. -D, --database=name Database to use. --default-character-set=name Set the default character set. --delimiter=name Delimiter to be used. --enable-cleartext-plugin Enable/disable the clear text authentication plugin. -e, --execute=name Execute command and quit. (Disables --force and history file.) -E, --vertical Print the output of a query (rows) vertically. -f, --force Continue even if we get an SQL error. --histignore=name A colon-separated list of patterns to keep statements from getting logged into syslog and mysql history. -G, --named-commands Enable named commands. Named commands mean this program's internal commands; see mysql> help . When enabled, the named commands can be used from any line of the query, otherwise only from the first line, before an enter. Disable with --disable-named-commands. This option is disabled by default. -i, --ignore-spaces Ignore space after function names. --init-command=name SQL Command to execute when connecting to MySQL server. Will automatically be re-executed when reconnecting. --local-infile Enable/disable LOAD DATA LOCAL INFILE. -b, --no-beep Turn off beep on error. -h, --host=name Connect to host. -H, --html Produce HTML output. -X, --xml Produce XML output. --line-numbers Write line numbers for errors. (Defaults to on; use --skip-line-numbers to disable.) -L, --skip-line-numbers Don't write line number for errors. -n, --unbuffered Flush buffer after each query. --column-names Write column names in results. (Defaults to on; use --skip-column-names to disable.) -N, --skip-column-names Don't write column names in results. --sigint-ignore Ignore SIGINT (CTRL-C). -o, --one-database Ignore statements except those that occur while the default database is the one named at the command line. --pager[=name] Pager to use to display results. If you don't supply an option, the default pager is taken from your ENV variable PAGER. Valid pagers are less, more, cat [> filename], etc. See interactive help (\h) also. This option does not work in batch mode. Disable with --disable-pager. This option is disabled by default. -p, --password[=name] Password to use when connecting to server. If password is not given it's asked from the tty. -P, --port=# Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306). --prompt=name Set the mysql prompt to this value. --protocol=name The protocol to use for connection (tcp, socket, pipe, memory). -q, --quick Don't cache result, print it row by row. This may slow down the server if the output is suspended. Doesn't use history file. -r, --raw Write fields without conversion. Used with --batch. --reconnect Reconnect if the connection is lost. Disable with --disable-reconnect. This option is enabled by default. (Defaults to on; use --skip-reconnect to disable.) -s, --silent Be more silent. Print results with a tab as separator, each row on new line. -S, --socket=name The socket file to use for connection. --server-public-key-path=name File path to the server public RSA key in PEM format. --get-server-public-key Get server public key --ssl-mode=name SSL connection mode. --ssl-ca=name CA file in PEM format. --ssl-capath=name CA directory. --ssl-cert=name X509 cert in PEM format. --ssl-cipher=name SSL cipher to use. --ssl-key=name X509 key in PEM format. --ssl-crl=name Certificate revocation list. --ssl-crlpath=name Certificate revocation list path. --tls-version=name TLS version to use, permitted values are: TLSv1, TLSv1.1, TLSv1.2, TLSv1.3 --ssl-fips-mode=name SSL FIPS mode (applies only for OpenSSL); permitted values are: OFF, ON, STRICT --tls-ciphersuites=name TLS v1.3 cipher to use. -t, --table Output in table format. --tee=name Append everything into outfile. See interactive help (\h) also. Does not work in batch mode. Disable with --disable-tee. This option is disabled by default. -u, --user=name User for login if not current user. -U, --safe-updates Only allow UPDATE and DELETE that uses keys. -U, --i-am-a-dummy Synonym for option --safe-updates, -U. -v, --verbose Write more. (-v -v -v gives the table output format). -V, --version Output version information and exit. -w, --wait Wait and retry if connection is down. --connect-timeout=# Number of seconds before connection timeout. --max-allowed-packet=# The maximum packet length to send to or receive from server. --net-buffer-length=# The buffer size for TCP/IP and socket communication. --select-limit=# Automatic limit for SELECT when using --safe-updates. --max-join-size=# Automatic limit for rows in a join when using --safe-updates. --show-warnings Show warnings after every statement. -j, --syslog Log filtered interactive commands to syslog. Filtering of commands depends on the patterns supplied via histignore option besides the default patterns. --plugin-dir=name Directory for client-side plugins. --default-auth=name Default authentication client-side plugin to use. --binary-mode By default, ASCII '\0' is disallowed and '\r\n' is translated to '\n'. This switch turns off both features, and also turns off parsing of all clientcommands except \C and DELIMITER, in non-interactive mode (for input piped to mysql or loaded using the 'source' command). This is necessary when processing output from mysqlbinlog that may contain blobs. --connect-expired-password Notify the server that this client is prepared to handle expired password sandbox mode. --network-namespace=name Network namespace to use for connection via tcp with a server. --compression-algorithms=name Use compression algorithm in server/client protocol. Valid values are any combination of 'zstd','zlib','uncompressed'. --zstd-compression-level=# Use this compression level in the client/server protocol, in case --compression-algorithms=zstd. Valid range is between 1 and 22, inclusive. Default is 3. Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf The following groups are read: mysql client The following options may be given as the first argument: --print-defaults Print the program argument list and exit. --no-defaults Don't read default options from any option file, except for login file. --defaults-file=# Only read default options from the given file #. --defaults-extra-file=# Read this file after the global files are read. --defaults-group-suffix=# Also read groups with concat(group, suffix) --login-path=# Read this path from the login file.

后面覆盖前面的配置文件，顺序如下： /etc/my.cnf Global选项 /etc/mysql/my.cnf Global选项 SYSCONFDIR/my.cnf Global选项（编译选项） $MYSQL_HOME/my.cnf Server-specific 选项 --defaults-extra-file=path （启动MySQL时使用该选项指定配置文件） ~/.my.cnf User-specific 选项
注意：以上顺序自上而下可同时指定多个配置文件，但谁在最下面谁的配置文件优先级最高，即后面的会覆盖前面的配置，类似于编程语言变量的定义。
三.基于yum方式安装Mariadb
基于默认的yum源时可以安装的MariaDB，但版本较低，可以基于yum方式安装MySQL一样去MariaDB官网找到对应版本的yum源下载安装即可。

[root@node102.yinzhengjie.org.cn ~]# mysql --help #查看mysql命令的帮助信息 mysql Ver 15.1 Distrib 5.5.64-MariaDB, for Linux (x86_64) using readline 5.1 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Usage: mysql [OPTIONS] [database] Default options are read from the following files in the given order: /etc/mysql/my.cnf /etc/my.cnf ~/.my.cnf The following groups are read: mysql client client-server client-mariadb The following options may be given as the first argument: --print-defaults Print the program argument list and exit. --no-defaults Don't read default options from any option file. The following specify which files/extra groups are read (specified before remaining options): --defaults-file=# Only read default options from the given file #. --defaults-extra-file=# Read this file after the global files are read. --defaults-group-suffix=# Additionally read default groups with # appended as a suffix. -?, --help Display this help and exit. -I, --help Synonym for -? --abort-source-on-error Abort 'source filename' operations in case of errors --auto-rehash Enable automatic rehashing. One doesn't need to use 'rehash' to get table and field completion, but startup and reconnecting may take a longer time. Disable with --disable-auto-rehash. (Defaults to on; use --skip-auto-rehash to disable.) -A, --no-auto-rehash No automatic rehashing. One has to use 'rehash' to get table and field completion. This gives a quicker start of mysql and disables rehashing on reconnect. --auto-vertical-output Automatically switch to vertical output mode if the result is wider than the terminal width. -B, --batch Don't use history file. Disable interactive behavior. (Enables --silent.) --binary-as-hex Print binary data as hex --character-sets-dir=name Directory for character set files. --column-type-info Display column type information. -c, --comments Preserve comments. Send comments to the server. The default is --skip-comments (discard comments), enable with --comments. -C, --compress Use compression in server/client protocol. -#, --debug[=#] This is a non-debug version. Catch this and exit. --debug-check Check memory and open file usage at exit. -T, --debug-info Print some debug info at exit. -D, --database=name Database to use. --default-character-set=name Set the default character set. --delimiter=name Delimiter to be used. -e, --execute=name Execute command and quit. (Disables --force and history file.) -E, --vertical Print the output of a query (rows) vertically. -f, --force Continue even if we get an SQL error. Sets abort-source-on-error to 0 -G, --named-commands Enable named commands. Named commands mean this program's internal commands; see mysql> help . When enabled, the named commands can be used from any line of the query, otherwise only from the first line, before an enter. Disable with --disable-named-commands. This option is disabled by default. -i, --ignore-spaces Ignore space after function names. --init-command=name SQL Command to execute when connecting to MySQL server. Will automatically be re-executed when reconnecting. --local-infile Enable/disable LOAD DATA LOCAL INFILE. -b, --no-beep Turn off beep on error. -h, --host=name Connect to host. -H, --html Produce HTML output. -X, --xml Produce XML output. --line-numbers Write line numbers for errors. (Defaults to on; use --skip-line-numbers to disable.) -L, --skip-line-numbers Don't write line number for errors. -n, --unbuffered Flush buffer after each query. --column-names Write column names in results. (Defaults to on; use --skip-column-names to disable.) -N, --skip-column-names Don't write column names in results. --sigint-ignore Ignore SIGINT (CTRL-C). -o, --one-database Ignore statements except those that occur while the default database is the one named at the command line. --pager[=name] Pager to use to display results. If you don't supply an option, the default pager is taken from your ENV variable PAGER. Valid pagers are less, more, cat [> filename], etc. See interactive help (\h) also. This option does not work in batch mode. Disable with --disable-pager. This option is disabled by default. -p, --password[=name] Password to use when connecting to server. If password is not given it's asked from the tty. -P, --port=# Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306). --progress-reports Get progress reports for long running commands (like ALTER TABLE) (Defaults to on; use --skip-progress-reports to disable.) --prompt=name Set the mysql prompt to this value. --protocol=name The protocol to use for connection (tcp, socket, pipe, memory). -q, --quick Don't cache result, print it row by row. This may slow down the server if the output is suspended. Doesn't use history file. -r, --raw Write fields without conversion. Used with --batch. --reconnect Reconnect if the connection is lost. Disable with --disable-reconnect. This option is enabled by default. (Defaults to on; use --skip-reconnect to disable.) -s, --silent Be more silent. Print results with a tab as separator, each row on new line. -S, --socket=name The socket file to use for connection. --ssl Enable SSL for connection (automatically enabled with other flags). --ssl-ca=name CA file in PEM format (check OpenSSL docs, implies --ssl). --ssl-capath=name CA directory (check OpenSSL docs, implies --ssl). --ssl-cert=name X509 cert in PEM format (implies --ssl). --ssl-cipher=name SSL cipher to use (implies --ssl). --ssl-key=name X509 key in PEM format (implies --ssl). --ssl-verify-server-cert Verify server's "Common Name" in its cert against hostname used when connecting. This option is disabled by default. -t, --table Output in table format. --tee=name Append everything into outfile. See interactive help (\h) also. Does not work in batch mode. Disable with --disable-tee. This option is disabled by default. -u, --user=name User for login if not current user. -U, --safe-updates Only allow UPDATE and DELETE that uses keys. -U, --i-am-a-dummy Synonym for option --safe-updates, -U. -v, --verbose Write more. (-v -v -v gives the table output format). -V, --version Output version information and exit. -w, --wait Wait and retry if connection is down. --connect-timeout=# Number of seconds before connection timeout. --max-allowed-packet=# The maximum packet length to send to or receive from server. --net-buffer-length=# The buffer size for TCP/IP and socket communication. --select-limit=# Automatic limit for SELECT when using --safe-updates. --max-join-size=# Automatic limit for rows in a join when using --safe-updates. --secure-auth Refuse client connecting to server if it uses old (pre-4.1.1) protocol. --server-arg=name Send embedded server this as a parameter. --show-warnings Show warnings after every statement. --plugin-dir=name Directory for client-side plugins. --default-auth=name Default authentication client-side plugin to use. --binary-mode By default, ASCII '\0' is disallowed and '\r\n' is translated to '\n'. This switch turns off both features, and also turns off parsing of all clientcommands except \C and DELIMITER, in non-interactive mode (for input piped to mysql or loaded using the 'source' command). This is necessary when processing output from mysqlbinlog that may contain blobs.

[root@node103.yinzhengjie.org.cn /usr/local/mysql/scripts]# ./mysql_install_db --help #查看该命令的帮助信息 Usage: ./mysql_install_db [OPTIONS] --auth-root-authentication-method=normal|socket Chooses the authentication method for the created initial root user. The default is 'normal' to creates a root user that can login without password, which can be insecure. The alternative 'socket' allows only the system root user to login as MariaDB root; this requires the unix socket authentication plugin. --auth-root-socket-user=user Used with --auth-root-authentication-method=socket. It specifies the name of the MariaDB root account, as well as of the system account allowed to access it. Defaults to 'root'. --basedir=path The path to the MariaDB installation directory. --builddir=path If using --srcdir with out-of-directory builds, you will need to set this to the location of the build directory where built files reside. --cross-bootstrap For internal use. Used when building the MariaDB system tables on a different host than the target. --datadir=path The path to the MariaDB data directory. --defaults-extra-file=name Read this file after the global files are read. --defaults-file=name Only read default options from the given file name. --defaults-group-suffix=name In addition to the given groups, read also groups with this suffix --force Causes mysql_install_db to run even if DNS does not work. In that case, grant table entries that normally use hostnames will use IP addresses. --help Display this help and exit. --ldata=path The path to the MariaDB data directory. Same as --datadir. --no-defaults Don't read default options from any option file. --defaults-file=path Read only this configuration file. --rpm For internal use. This option is used by RPM files during the MariaDB installation process. --skip-auth-anonymous-user Do not install an unprivileged anonymous user. --skip-name-resolve Use IP addresses rather than hostnames when creating grant table entries. This option can be useful if your DNS does not work. --srcdir=path The path to the MariaDB source directory. This option uses the compiled binaries and support files within the source tree, useful for if you don't want to install MariaDB yet and just want to create the system tables. --user=user_name The login username to use for running mysqld. Files and directories created by mysqld will be owned by this user. You must be root to use this option. By default mysqld runs using your current login name and files and directories that it creates will be owned by you. All other options are passed to the mysqld program [root@node103.yinzhengjie.org.cn /usr/local/mysql/scripts]# [root@node103.yinzhengjie.org.cn /usr/local/mysql/scripts]#

3>.cmake编译安装
cmake的重要特性之一是其独立于源码(out-of-source)的编译功能，即编译工作可以在另一个指定的目录中而非源码目录中进行，这可以保证源码目录不受任何一次编译的影响，因此在同一个源码树上可以进行多次不同的编译，如针对于不同平台编译
编译选项:

9>.安全初始化(运行"mysql_secure_installation"脚本以提高安全性)
[root@node104.yinzhengjie.org.cn ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! [root@node104.yinzhengjie.org.cn ~]# [root@node104.yinzhengjie.org.cn ~]#
