centos 7 MysSQL 5.7.23 源码安装
MySQL 5.7.23 源码安装
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
