当前系统:centos7.1mini
在/etc/yum.repos.d/MariaDB.repo添加MariaDB yum源
在shell窗口无参数执行如下命令:
mysql_secure_installation
grant语句创建用户并授权
GRANT语句的语法看上去像这样:
GRANT privileges (columns) ON what TO user IDENTIFIED BY "password" WITH GRANT OPTION
要使用该语句,你需要填写下列部分:
privileges
授予用户的权限,下表列出可用于GRANT语句的权限指定符:
权限指定符 权限允许的操作
ALTER 修改表和索引
CREATE 创建数据库和表
DELETE 删除表中已有的记录
详细信息请参考链接grant
在/etc/yum.repos.d/MariaDB.repo添加MariaDB yum源
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1安装mariadb:
yum install MariaDB-server MariaDB-client安装完成后启动mariadb服务
service mariadb start或者
systemctl start mariadbmariadb安装后需要设置安全,包括密码,匿名用户等
在shell窗口无参数执行如下命令:
mysql_secure_installation
[root@localhost toolcase]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
