一、安装约定 mysql安装路径: /usr/local/mysql mysql数据库路径: /data/mysql my配置文件路径: /usr/local/mysql/my.cnf 二、卸载mariadb # rpm -qa | grep mariadb# rpm -e --nodeps mariadb-libs-5.5.37-1.el7_0.x86_64 包名
一、安装约定
mysql安装路径: /usr/local/mysql
mysql数据库路径: /data/mysql
my配置文件路径: /usr/local/mysql/my.cnf
二、卸载mariadb
# rpm -qa | grep mariadb
# rpm -e --nodeps mariadb-libs-5.5.37-1.el7_0.x86_64 包名是上一条查询得知
三、创建用户组、用户
添加mysql组 groupadd mysql
添加用户 useradd -g mysql mysql -s /bin/false

```
更改权限
```
# chmod 755 /var/lib/mysql
# cd /usr/local/mysql
# chown -R mysql:mysql .
初始化mysql
/usr/local/mysql/bin/mysqld --initialize --basedir=/usr/local/mysql --datadir=/data/mysql --user=mysql --explicit_defaults_for_timestamp=1
创建mysql配置文件
