Mariadb
1.配置数据库yum源
[root@web-001 ~]# cat /etc/yum.repos.d/MariaDB.repo # MariaDB 10.1 CentOS repository list - created 2016-05-12 09:28 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
至MariaDB.repo文件,保存文件并退出
安装数据库:
yum install MariaDB-server MariaDB-client -y
2.Mariadb服务
启动服务:
systemctl start mariadb.service
停止服务:
systemctl stop mariadb.service
重启服务:
systemctl restart mariadb.service
查看状态
systemctl status mariadb.service
3.生产服务器需要执行mysql_secure_installation
[root@web-001 ~]# /usr/bin/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] n //是否设置root密码 ... skipping. 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 //是否删除匿名用户 ... 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 //是否允许root远程登陆 ... 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 //是否删除test库 - 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 //重新刷新授权 ... 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!
登陆mysql
[root@web-001 ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 8 Server version: 10.1.14-MariaDB MariaDB Server Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | +--------------------+ 3 rows in set (0.00 sec) MariaDB [(none)]> Bye
设置root密码
‘/usr/bin/mysqladmin‘ -u root password ‘new-password‘ ‘/usr/bin/mysqladmin‘ -u root -h iZ250234rf8Z password ‘new-password‘
