mysql社区版安装(centos7.2)

一、添加Mysql的yum源

wget https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
#rpm -Uvh platform-and-version-specific-package-name.rpm
rpm -Uvh mysql80-community-release-el7-1.noarch.rpm

二、选择realse版本

yum repolist all | grep mysql
#我觉得这个不需要
yum-config-manager --disable mysql80-community
#查检一下
yum repolist enabled | grep mysql

三、安装

yum install mysql-community-server

四、启动服务

systemctl start mysqld.service
#检查是否正常启动
systemctl status mysqld.service

五、设置root用户

#root的临时密码
grep 'temporary password' /var/log/mysqld.log
#登录，密码在上条命令的结果中
mysql -uroot -p
#设置root密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
