2.5 初始化数据库

2.5.1 更改MySQL安装目录的属主和属组

[root@192168066012_MySQL_5_7_27 ~]# chown -R mysql:mysql /application/mysql/

2.5.2 修改my.cnf文件的属主和属组

[root@192168066012_MySQL_5_7_27 ~]# chown mysql:mysql /etc/my.cnf

2.5.3 修改my.cnf配置文件

#修改/etc/my.cnf文件，和5.6之前的版本不一样，5.7版本support-files目录下没有.cnf文件，因此，需要自己手动编辑

  1. [root@192168066012_MySQL_5_7_27 ~]# cp /etc/my.cnf /etc/my.cnf.bak
  2. [root@192168066012_MySQL_5_7_27 ~]# vim /etc/my.cnf

  21. log-bin = /application/mysql/binlog/mysql-bin
  22. log-error = /application/mysql/logs/mysql_5_7_27.err

my.cnf文件常用选项详解
[client]
#默认连接端口
port = 3306
#用于本地连接的socket套接字
socket = /application/mysql/tmp/mysql.sock
#编码
default-character-set = utf8

[mysqld]
#服务端口号，默认3306
port = 3306
#mysql启动用户
user = mysql
#mysql安装根目录
basedir = /application/mysql
#mysql数据文件所在位置
datadir = /application/mysql/data
#pid文件所在目录
pid-file = /application/mysql/mysqld.pid
#为MySQL客户端程序和服务器之间的本地通讯指定一个套接字文件
socket = /application/mysql/tmp/mysql.sock
#MySQL存放临时文件的目录
tmpdir = /application/mysql/tmp
#数据库默认字符集,主流字符集支持一些特殊表情符号(特殊表情符占用4个字节)
character_set_server = utf8
#MySQL服务的唯一编号，每个mysql服务Id需唯一
server-id = 1
#最大连接数
max_connections = 100
#最大错误连接数
max_connect_errors = 10
#sql_mode,定义了mysql应该支持的sql语法，数据校验
#NO_ENGINE_SUBSTITUTION：如果需要的存储引擎被禁用或未编译，可以防止自动替换存储引擎
#STRICT_TRANS_TABLES：存储引擎启用严格模式，非法数据值被拒绝
#NO_AUTO_CREATE_USER：禁止GRANT创建密码为空的用户
#NO_AUTO_VALUE_ON_ZERO：默认情况下自增长列是从1开始的，如果你插入值为0的数据会报错，设置这个之后就可以正常插入为0的数据了
#NO_ZERO_IN_DATE：在严格模式，不接受月或日部分为0的日期
#NO_ZERO_DATE：在严格模式，不要将 ‘0000-00-00′做为合法日期
#ERROR_FOR_DIVISION_BY_ZERO：在严格模式，在INSERT或UPDATE过程中，如果被零除(或 MOD(X，0))，则产生错误(否则为警告)。如果未给出该模式，被零除时MySQL返回NULL
#PIPES_AS_CONCAT：将||视为字符串连接操作符（＋）(同CONCAT())，而不视为OR
#ANSI_QUOTES：将‘”'视为识别符引号(‘`'引号字符)，不要视为字符串的引号字符
sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
#开启二进制日志功能，binlog数据位置
log-bin = /application/mysql/binlog/mysql-bin
#mysql生成的错误日志存放的路径
log-error = /application/mysql/logs/mysql_5_7_27.err

2.5.4 初始化数据库

  1. [root@192168066012_MySQL_5_7_27 ~]# cd /application/mysql/
  2. [root@192168066012_MySQL_5_7_27 mysql]# ./bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

提示：
#生成初始化密码参数(5.7版本才有)，必须要添加，否则会初始化失败，会生成空密码
--initialize-insecure
#设定初始化用户
--user=mysql
#设定mysql工作目录
--basedir=/application/mysql

2.5.5 实例开启SSL连接

  1. [root@192168066012_MySQL_5_7_27 mysql]# cd /application/mysql/
  2. [root@192168066012_MySQL_5_7_27 mysql]# ./bin/mysql_ssl_rsa_setup --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

2.5.6 修改data目录下的server-key.pem文件权限

  1. [root@192168066012_MySQL_5_7_27 ~]# cd /application/mysql/data/
  2. [root@192168066012_MySQL_5_7_27 data]# chmod +r server-key.pem
  3. [root@192168066012_MySQL_5_7_27 data]# ls -l server-key.pem
  4. -rw-r--r-- 1 root root 1675 Jul 31 20:01 server-key.pem

提示：
如果不给文件server-key.pem其他用户和组可读权限的话，当启动数据库的时候，会报如下错误
2019-08-07T06:39:24.111526Z 0 [ERROR] SSL error: Unable to get private key from 'server-key.pem'

2.6 启动MySQL数据库

#拷贝启动脚本到/etc/init.d/目录下，并改名mysqld

  1. [root@192168066012_MySQL_5_7_27 mysql]# cp support-files/mysql.server /etc/init.d/mysqld
  2. [root@192168066012_MySQL_5_7_27 mysql]# ls -l /etc/init.d/mysqld
  3. -rwxr-xr-x 1 root root 10588 Aug 1 18:33 /etc/init.d/mysqld

#重新加载系统服务，将MySQL数据库加入开机自启动

  1. [root@192168066012_MySQL_5_7_27 ~]# /bin/systemctl daemon-reload
  2. [root@192168066012_MySQL_5_7_27 ~]# /bin/systemctl enable mysqld.service
  3. mysqld.service is not a native service, redirecting to /sbin/chkconfig.
  4. Executing /sbin/chkconfig mysqld on

#启动MySQL数据库，并检查端口监听状态

  1. [root@192168066012_MySQL_5_7_27 ~]# /etc/init.d/mysqld start
  2. Starting MySQL. SUCCESS!
  3. [root@192168066012_MySQL_5_7_27 ~]# netstat -lntup
  4. Active Internet connections (only servers)
  5. Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
  6. tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 6549/sshd
  7. tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 7023/master

  9. tcp6 0 0 :::22 :::* LISTEN 6549/sshd
  10. tcp6 0 0 ::1:25 :::* LISTEN 7023/master

提示：
默认CentOS 7默认没有netstat命令，而是使用ss命令代替；如果想使用netstat命令的话，需要执行yum install net-tools进行安装net-tools软件包，然后就可以使用了；

2.8 优雅关闭MySQL数据的方法

#使用MySQL自带的脚本

  1. [root@192168066012_MySQL_5_7_27 ~]# /etc/init.d/mysqld stop
  2. Shutting down MySQL. SUCCESS!

#使用mysqladmin的方法

  1. [root@192168066012_MySQL_5_7_27 mysql]# mysqladmin -uboyu -pboyu123 shutdown
  2. mysqladmin: [Warning] Using a password on the command line interface can be insecure.
  3. #mysqladmin:[警告]在命令行界面上使用密码可能不安全

提示：
5.7版本优化了数据库的安全配置，建议配置SSL加密连接，默认在命令行输入的密码都是明文传输的，极为不安全；

2.9 授权远程用户连接MySQL数据的方法

#授权192.168.88.1对MySQL所有库和所有表都赋予boyu用户权限；

  1. mysql> grant all privileges on *.* to boyu@'192.168.66.11' identified by 'boyu123' with grant option;
  2. Query OK, 0 rows affected, 1 warning (0.00 sec)
  3.  
  4. mysql> flush privileges;
  5. Query OK, 0 rows affected (0.00 sec)
  6.  
  7. mysql> select user,host from mysql.user;
  8. +------+---------------+
  9. | user | host |
  10. +------+---------------+
  11. | boyu | 192.168.66.11 |
  12. | boyu | localhost |
  13. +------+---------------+
  14. 2 rows in set (0.00 sec)

#测试远程登陆

  1. [root@192168066011 ~]# mysql -h192.168.66.12 -uboyu -pboyu123 -P3306

3 案例和MySQL 5.7编译安装报错信息整理

3.1 MySQL数据库使用kill的故障案例

625某电商网站数据库宕机故障解决实录（上）
625某电商网站数据库宕机故障解决实录（下）
提示：
不要野蛮粗鲁杀死数据库，生产高并发环境会导致数据丢失

3.2 编译安装MySQL报错

#未指定boost库，MySQL 5.7版本使用cmake配置编译参数时，强依赖boost
CentOS 7.6源码编译安装MySQL 5.7.27

解决办法：

  • MySQL 5.7版本对应的boost库版本为：boost_1_59_0.tar.gz，本文已提供下载连接
  • 将boost_1_59_0下载到本地，放在/usr/local/目录下
  • 添加cmake参数“-DWITH_BOOST=/usr/local/boost”，指定boost目录位置

#找不到CURSES_LIBRARY
CentOS 7.6源码编译安装MySQL 5.7.27

解决办法：
yum install ncurses-devel -y

#make过程，报内存不足错误
CentOS 7.6源码编译安装MySQL 5.7.27

解决办法：
增加内存空间，或者swap空间
