Centos下MySQL Mariadb 的安裝

因為centos預設的資料庫是mariadb，所以安裝很簡單，只需要使用yum安裝即可。

[root@bogon ~]# yum -y install mariadb-server mariadb

[root@bogon ~]# rpm -qi mariadb #檢視是否安裝成功

還有一點，在centos中，執行yum -y install mysql mysql-server其實安裝的是mariadb。

啟動mariadb並加入開機自啟

[root@bogon ~]# systemctl start mariadb

[root@bogon ~]# systemctl enable mariadb
created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@bogon ~]# 

首次安裝，mariadb的密碼預設為空，所以輸密碼時直接敲回車就行。還有一點要注意：mariadb的命令和mysql的命令幾乎一模一樣。

[root@bogon ~]# mysql
