记录下在 CentOS 6.9 环境安装 MySQL 5.6.37 的过程,供大家参考。

1、准备数据存放的文件系统
新建一个逻辑卷,并将其挂载至特定目录即可。这里不再给出过程。
这里假设其逻辑卷的挂载目录为 /data,而后需要创建 /data/mysqldata 目录做为 mysql 数据的存放目录。
[root@001 /]# mkdir -p /data/mysqldata

2、新建用户以安全方式运行进程:
[root@001 ~]# useradd mysql -s /sbin/nologin -M
[root@001 ~]# chown -R mysql:mysql /data/mysqldata

3、安装并初始化 mysql
[root@001 ~]# wget https://cdn.mysql.com//Downloads/MySQL-5.6/mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz
[root@001 ~]# tar -xf mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz -C /usr/local/src/
[root@001 ~]# cd /usr/local/
[root@001 local]# ln -sv /usr/local/src/mysql-5.6.37-linux-glibc2.12-x86_64/ mysql  #根据实际情况修改
[root@001 local]# cd mysql
[root@001 mysql]# chown -R mysql:mysql .

4. 为 mysql 提供主配置文件: #默认初始化后会在 /etc 下有 my.cnf,如有内容删除覆盖即可

配置文件

[root@001 mysql]# yum install libaio* libnuma* -y  #安装依赖
[root@001 mysql]# vim /etc/my.cnf

———————————————————————————————————————————————————–
[root@001 mysql]# scripts/mysql_install_db –user=mysql –datadir=/data/mysqldata/
[root@001 mysql]# chown -R root .

5、为 mysql 提供 sysv 服务脚本:
[root@001 mysql]# cd /usr/local/mysql
[root@001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@001 mysql]# ldconfig

6、修改 PATH 环境变量,让系统可以直接使用 mysql 的相关命令。
[root@001 mysql]#  echo “PATH=$PATH:/usr/local/mysql/bin” > /etc/profile.d/mysql.sh
[root@001 mysql]# source /etc/profile.d/mysql.sh

7、最后启动服务添加开机启动
[root@001 mysql]# service mysqld start
[root@001 mysql]# chkconfig mysqld on
[root@001 bin]# ./mysqladmin -u root password ‘123456’
[root@001 bin]# mysql -uroot -p123456
