Centos7 yum安装mariadb
1 配置yum源安装 yum配置文件 /etc/yum.repos.d
yum install mariadb mariadb-server
2 修改root用户默认密码
update user set password=password("xxxx") where user="root"; 修改root用户密码
flush privileges; 刷新权限,
3.开放远程端口权限,在mysql表内执行
创建用户命令
mysql>create user 'username'@'localhost' identified by 'password';
直接创建用户并授权的命令
mysql>grant all on *.* to 'username'@'localhost' indentified by 'password';
授予外网登陆权限
mysql>grant all privileges on *.* to 'username'@'%' identified by 'password';
授予权限并且可以授权
mysql>grant all privileges on *.* to 'username'@'hostname' identified by 'password' with grant option;
刷新权限
flush privileges;
这样就已x就安装完成了,缺乏机器练手的小伙伴们可以去3A服务器看看!
