MySQL 5.6.39 二进制安装
CentOS 7 将默认数据库
MySQL替换成了Mariadb。
这里会从系统的环境准备开始一步一步安装。
环境准备
| 系统版本 | 内核版本 | IP地址 |
|---|---|---|
| Centos 7.5 | 4.18.9-1.el7.elrepo.x86_64 | 10.0.0.3 |
备注 该系统采用MINI最小化安装，安装之后对系统进行了最基础的优化操作，操作过程点击这里
删除系统自带的依赖包
[root@node soft]# rpm -qa | egrep 'mysql|mariadb'
mariadb-libs-5.5.56-2.el7.x86_64
[root@node soft]# rpm -qa | egrep 'mysql|mariadb' | xargs rpm -e --nodeps
[root@node soft]# rpm -qa | egrep 'mysql|mariadb'
[root@node soft]#
创建MySQL运行用户
[root@node soft]# useradd -s /sbin/nologin -M mysql
[root@node soft]# grep mysql /etc/passwd
mysql:x:1000:1000::/home/mysql:/sbin/nologin
下载 MySQL
可以在mirrors.163.com的163源下载，点击我下载

[root@node ~]# cd /opt/soft/
[root@node soft]# wget http://mirrors.163.com/mysql/Downloads/MySQL-5.6/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@node soft]# ls
mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
# 解压
[root@node soft]# tar xf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@node soft]# ls
mysql-5.6.39-linux-glibc2.12-x86_64 mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
配置环境变量
[root@node soft]# mv mysql-5.6.39-linux-glibc2.12-x86_64 /opt/mysql
[root@node soft]# chown -R mysql.mysql /opt/mysql
[root@node soft]# cd /opt/
[root@node opt]# ls
mysql
[root@node opt]# echo 'export PATH=$PATH:/opt/mysql/bin' >> /etc/profile
[root@node opt]# tail -1 /etc/profile
export PATH=$PATH:/opt/mysql/bin
[root@node opt]# source /etc/profile
[root@node opt]# mysql -V
mysql Ver 14.14 Distrib 5.6.39, for linux-glibc2.12 (x86_64) using EditLine wrapper
配置MySQL启动脚本并设置开机自启
二进制解压后的目录中，包括了MySQL的启动关闭脚本，可以使用，也可以自己写
systemctl管理脚本
[root@node opt]# cd mysql/
[root@node mysql]# pwd
/opt/mysql
[root@node mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@node mysql]# chmod +x /etc/init.d/mysqld
[root@node mysql]# sed -i 's#/usr/local#/opt#g' /etc/init.d/mysqld
[root@node mysql]# chkconfig --add mysqld
[root@node mysql]# chkconfig mysqld on
[root@node mysql]# chkconfig | grep mysql
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
