CenterOS7下快速安装mysql_centeros7 yum mysql

centos7下快速安装mysql
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('123456');
mysql> exit
搞定！


查询用户表
use mysql
select host,user,password from user;




通过mysql命令进入之后
执行sql：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
delete from user where host !='%';
flush privileges;


退出重新登录


通过
mysql -u root -p
