基于某些特定原因需要再CentOS7上安装MySQL

CentOS 7 利用yum源安装MySQL

在CentOS7上添加MySQL的yum仓库源

• 这里我们使用国内清华大学的yum源，速度比较快

cat > /etc/yum.repos.d/mysql-community.repo <<SUN

找到喜欢的rpm包wget

wget  https://mirrors.tuna.tsinghua.edu.cn/mysql/yum/mysql80-community-el7/mysql-community-server-8.0.25-1.el7.x86_64.rpm

[root@c7-182 ~]# ll -h mysql-community-server-8.0.25-1.el7.x86_64.rpm 
-rw-r--r-- 1 root root 428M Apr 26 15:38 mysql-community-server-8.0.25-1.el7.x86_64.rpm

使用yum安装同时解决依赖

yum -y install ./mysql-community-server-8.0.25-1.el7.x86_64.rpm

启动并设为开机启动

systemctl enable --now mysql.service

安装后进行安全设置

• 运行自带安全脚本进行安全设置

mysql_secure_installation
