CentOS 7的yum源中貌似没有正常安装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 -uroot mysql> set password for ‘root’@‘localhost’ = password('mypasswd'); mysql> exit |
搞定！
设置 远程访问 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'MyPassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
开启防火墙
yum install -y iptables
然后编辑系统的开放端口列表，增加3306端口，重启防火墙即可。
