+# MariaDB 安装配置与使用
+
+MariaDB 是与 MySQL 兼容的开源实现，当 Linux 服务器上需要使用 MySQL 时可以用 MariaDB 替代。  
+
+## 安装
+
+MariaDB 的安装命令如下：  
+
+```sh
+## Arch Linux
+pacman -S mariadb mariadb-clients mariadb-libs
+## Ubuntu
+apt-get install mariadb-server mariadb-client libmariadbclient-dev
+```
+
+## 初始配置
+
+安装完 MariaDB 后需要进行初始配置，首先需要执行以下命令：  
+
+```sh
+mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
+```
+
+之后启动 MariaDB 的系统服务：  
+
+```sh
+systemctl start mariadb
+```
+
+最后初始化数据库：  
+
+```sh
+mysql_secure_installation
+
+    Switch to unix_socket authentication [Y/n] n
+    Change the root password? [Y/n] Y
+    Remove anonymous users? [Y/n] Y
+    Disallow root login remotely? [Y/n] n
+    Remove test database and access to it? [Y/n] Y
+    Reload privilege tables now? [Y/n] Y
+     ... Success!
+```
+
+## 基本维护
+
+```sh
+# 进入 MariaDB 交互模式
+mariadb -u root -p
+# 显示所有数据库
+show databases;
+# 删除数据库
+drop database <database name>;
+# 选择操作的数据库
+use mysql;
+# 更改密码
+update user set authentication_string=PASSWORD('passwd') where User='root';
+# 如果没这一行可能也会报一个错误，因此需要运行这一行
+update user set plugin="mysql_native_password";
+# 强制写入
+flush privileges;
+# 退出
+quit;
+# 重启 MariaDB 服务使新的配置生效
+systemctl restart mariadb
+```
