#询问是否要安装，输入Y即可自动安装
mariaDBde 服务的基本命令
[root@127 ~]# systemctl start mariadb.service #启动MariaDB [root@127 ~]# systemctl stop mariadb.service #停止MariaDB [root@127 ~]# systemctl restart mariadb.service #重启MariaDB [root@127 ~]# systemctl enable mariadb.service #设置开机自动启动
[root@127 ~]# systemctl disenable mariadb.service #设置开机自启关闭
初始化root密码
[root@127 ~]# mysql_secure_installation #为初始化账户root添加密码 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):这里填写root密码，如果是第一次初始化密码为空直接敲回车（回车前）
Enter current password for root (enter for none):这里填写root密码，如果是第一次初始化密码为空直接敲回车 （回车后↓） OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have a root password set, so you can safely answer ‘n‘. Change the root password? [Y/n] y New password: 这里填写新的密码 Re-enter new password: 这里填写重复的密码 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... ERROR 1008 (HY000) at line 1: Can‘t drop database ‘test‘; database doesn‘t exist ... Failed! Not critical, keep moving... - 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!
# 这里表示修改密码成功
数据库登录
[root@127 ~]# mysql -uroot -proot
# mysql -u这里是填写的用户名（默认为root） &我是空格& -p这里填写的是密码（默认为空）
这表示已经进入MariaDB
Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 23 Server version: 5.5.50-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. # 通过/h可以查看很多命令 MariaDB [(none)]> 这里是输入sql语句的入口
