先检查是否存在已安装的MySQL

# yum list installed | grep mysql

若存在删除:

yum remove 软件名称

CentOS 7的yum源中没有正常安装mysql时的mysql-sever文件,需要去官网上下载 

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

# rpm -ivh mysql-community-release-el7-5.noarch.rpm

# yum install mysql-community-server

成功安装之后重启mysql服务

 # service mysqld restart

初次安装mysql是root账户是没有密码的

设置密码的方法

# mysql -u root
  mysql> set password for 'root'@'localhost' = password('666');
  mysql> exit

搞定!

mysql在安装完成后mysql.user表中有多个用户,建议清除除root以外的其他用户,保证安全和不必要的bug

mysql> delete from mysql.user where host != 'localhost' or user !='root';
mysql> exit
