一、安装mysql: 位置位于 /data/mysql
如果遇到依赖,无法删除,使用 rpm -e --nodeps <包的名字> 不检查依赖,直接删除rpm包

---5.0-源码编译mysql------------------------------------------------------------
mysql软件目录: -DCMAKE_INSTALL_PREFIX
mysql数据目录: -DMYSQL_DATADIR
[root@UMS-DATA-SLAVE mysql-5.7.22]# time cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/ -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_BOOST=/usr/local/boost -DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock
一定记得无报错,才行!!!
[root@UMS-DATA-SLAVE mysql-5.6.16]# make
[root@UMS-DATA-SLAVE mysql-5.6.16]# make install
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++问题1: 《mysql5.7 必须安装2.9以上的cmake》++++++++
bash: cmake: 未找到命令...
tar -xzvf cmake-2.6.4.tar.gz
cd cmake-2.6.4
依次执行:
./bootstrap
make
make install
++++++++问题2:+++++++++++++
mysql5.7.28 安装过程 报错CMake Error at cmake/boost.cmake:81 (MESSAGE)
CMake Error at cmake/boost.cmake:81 (MESSAGE):
You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=
问题描述:高版本mysql需要boots库的安装才可以正常运行
解决办法:
1.在/usr/local下创建一个名为boost的文件夹
mkdir -p /usr/local/boost
2.进入这个新创建的文件夹然后下载boost
wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
3.解压
tar -xvzf boost_1_59_0.tar.gz
4.继续cmake,添加上红色部分
即安装后运行:
因为boost并不需要我们安装,只需要放到指定的目录,在安装mysql的时候,指定boost目录即可,再次我将解压后的文件移动到/usr/local/boost目录中。
5.然后回到mysql安装。 只需要加上:-DWITH_BOOST=/usr/local/boost 即可
++++++++问题3:++++++++++
CMake Error at cmake/readline.cmake:83(MESSAGE):Curses library not found.
解决方法:
安装ncurses-devel:
yum -y install ncurses-devel(Debian/Ubuntu需安装libncurses5-dev)
删除mysql解压目录 , 重新执行编译mysql安装
make[2]: *** [sql/CMakeFiles/sql.dir/item_geofunc_setops.cc.o] 错误 4
++++++++问题4:+++++++++++
make && make install 命令 执行到49% 报 c++: 编译器内部错误:已杀死(程序 cc1plus)
内存不足,mysql 5.5以上版本编译需要1G以上内存,可以编译安装mysql5.5
解决方法: linux dd 增加swap 内存
++++++++问题5:++++++++++

---6.0-添加环境变量------------------------------------------------------------
方法一:
[root@ums-data support-files]# vi /root/.bash_profile
在PATH=$PATH:$HOME/bin添加参数为:
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib
[root@ rhel5~]#source /root/.bash_profile
方法二:
[root@query-db data]# echo 'export PATH=$PATH:/usr/local/mysql/bin' >> /etc/profile
[root@query-db data]# source /etc/profile
---7.0-建立多实例目录------------------------------------------------------------
[root@UMS-DATA-SLAVE scripts]# pwd
/usr/local/mysql/scripts ---------这个目录是 make install 系统自动时候建立的
[root@query-db data]# mkdir -p /data/{mysql3306,mysql3307}
[root@query-db data]# ll
[root@query-db data]# mkdir /data/mysql3306/{log,tmp} ##千万不要建/data/ 听网上人瞎写
更改目录权限
[root@query-db data]# chown -R mysql:mysql /usr/local/mysql/
[root@query-db data]# chown -R mysql:mysql /data/
5.7新特性
cp /etc/my.cnf /data/mysql3306/my3306.cnf
cp /etc/my.cnf /data/mysql3307/my3307.cnf

--8.0-安装数据库------------------------------------------------------------
--8.1-初始化数据库

注意:所以要把data directory文件删除掉再执行,如果删除目录下的文件还是报同样的错,可以试试把目录删除掉,再创建一个,然后授权:
--8.2-初始化3306数据库
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3306/data --defaults-file=/data/mysql3306/my3306.cnf
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3307/data --defaults-file=/data/mysql3306/my3306.cnf
注意:1.每次执行都会生成 data/ 文件夹,如果中途失败,就要手动删除!!
2.这一步执行完,/data/mysql3307/data 下就生成数据库文件了。
--defaults-file="/data/mysql3306/my3306.cnf"
--9.0-启动mysql数据库------------------------------------------------------------
[root@ rhel5 mysql]#/usr/local/mysql/bin/mysqld_safe --user=mysql & //启动MySQL,但不能停止

回车,直接进去mysql
创建自动启动文件
# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld3306 ---增加mysqld 服务
# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld3307
# chmod 755 /etc/rc.d/init.d/mysqld3306
# chmod 755 /etc/rc.d/init.d/mysqld3307
# vi /etc/rc.d/init.d/mysqld3306 #编辑 (3306,3307同理)
basedir=/usr/local/mysql #MySQL程序安装路径
datadir=/data/mysql3306/data #MySQl数据库存放目录
修改(注意格式 空格和缩进 不要动)
$bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &
变成
$bindir/mysqld_safe --defaults-file="$datadir/my.cnf" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &
---bayaim:我是这个=样改的
--defaults-file="/data/mysql3307/my3307.cnf"
关闭MySQL服务
[root@ rhel5 mysql]# mysqladmin -u root -p shutdown //这里MySQL的root用户还没有配置密码,所以为空值。需要输入密码时,直接点回车键即可。
# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld3306
#复制脚本 :
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3306 ---增加mysqld 服务
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3307 ---增加mysqld 服务
#增加可执行权限 :
[root@orcl init.d]# chmod +x /etc/init.d/mysqld3306
[root@orcl init.d]# chmod +x /etc/init.d/mysqld3307
#增加至sysV服务 :
[root@orcl init.d]# chkconfig --add mysqld3306
[root@orcl init.d]# chkconfig --add mysqld3307
#开机自启动:
[root@orcl init.d]# chkconfig mysqld3306 on
[root@orcl init.d]# chkconfig mysqld3307 on
#启动mysql服务:

--10.0-修改mysql密码------------------------------------------------------------
--10.1-登录
修改MySQL的root用户的密码以及打开远程连接
[root@UMS-DATA-SLAVE mysql]# mysql -uroot -p
Enter password:
回车
直接进去
--10.2-修改密码
MySQL5.7 加强了安全保障,以上意思是密码不符合安全策略要求,我们输入一个8位或以上长度,复杂一点的密码,比如:
mysql>use mysql;
mysql>desc user;
mysql>GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'rootBPY123.#' WITH GRANT OPTION;
mysql>update mysql.user set authentication_string=password('rootBPY123.#') where user='root' ;
删除空用户
mysql>DELETE FROM mysql.user WHERE user='';
mysql>flush privileges;
mysql>exit
--10.3-重新登录mysql------------------------------------------------------------
mysql --socket=/data/mysql3306/mysql.sock -uroot -prootBPY123.#
mysql --socket=/data/mysql3307/mysql.sock -uroot -prootBPY123.#
导入数据:
mysql> source /bayaim/bai_all_12.sql

若还不能进行远程连接,则关闭防火墙
[root@ rhel5~]# /etc/rc.d/init.d/iptables stop
[root@ums-data-bak mysql]# service iptables stop
防火墙
[root@ums-data mysql]# chkconfig iptables off
[root@ums-data mysql]# iptables -F (清空防火墙默认规则)
[root@ums-data mysql]# systemctl stop firewalld.service (停止防火墙,这是CentOS7的命令)
[root@ums-data mysql]# systemctl disable firewalld //禁止开机启动
查看端口:
[root@ums-data mysql]# netstat -nutlp | grep 330
[root@ums-data mysql]# mysql -uroot -p -h192.168.66.143 -P3306
---------------------------
每次登陆 不需要密码登陆:
[root@oradata ~]# mysql_config_editor set --login-path=client --host=localhost --user=root --password --socket=/mysql/mysql3308/mysql3308.sock
[root@oradata ~]# pwd
/root
[root@oradata ~]# cat .mylogin.cnf
然后就可以无密码登陆了:
[root@oradata ~]# mysql --login-path=client
