rpm -qa | grep -i mysql
rpm -qa | grep -i mariadb
rpm -e xxxx
#注:如上命令删除不成功,有别的软件依赖无法删除时,如下操作:
yum remove xxxx
或
rpm -e --nodeps xxxx
```
2. 关闭seLinux
一、查看SELinux状态命令:
1、/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
2、getenforce ##也可以用这个命令检查
二、关闭SELinux方法:
1、临时关闭(不用重启机器):
代码如下:
setenforce 0 #设置SELinux 成为 permissive 模式 放任的 关闭
#setenforce 1 设置SELinux 成为 enforcing 模式 强制执行 打开
2、修改配置文件需要重启机器:
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可
3.下载源码包安装依赖
// 初始化目录
mkdir -p /data/mysql/data
mkdir -p /data/mysql/tmp
mkdir -p /data/mysql/binlog
mkdir -p /data/mysql/logs
mkdir -p /data/boost
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql
-s /sbin/nologin 用户不能登录系统
-M 不创建用户的home家目录
-g 指定用户登录组的gid或组名
id mysql
