CentOS 使用yum安装MYSQL

wget -i http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum -y install mysql57-community-release-el7-7.noarch.rpm
yum -y install mysql-community-server
systemctl start  mysqld.service

使用YUM安装并启动MySQL服务后，MySQL进程会自动在进程日志中打印root用户的初始密码：

[[email protected] ~]# mysql -uroot -p
Enter password:             #######输入默认的root密码后回车
