mariadb-server 安裝後沒有 mysqld 或 mysql.server

所以……可能我是個白痴，但我被困住了。我剛剛在 Digial Ocean 上設置了 CentOS 7，但我似乎無法讓 MariaDB/MySQL 伺服器執行。

一些輸出

[root@hostname ~]# yum list installed |grep maria
mariadb.x86_64                        1:5.5.37-1.el7_0                @updates  
mariadb-libs.x86_64                   1:5.5.37-1.el7_0                @updates  
mariadb-server.x86_64                 1:5.5.37-1.el7_0                @updates  

所以它已經安裝了，我們至少可以看到客戶端嗎？

[root@hostname ~]# which mysql
/bin/mysql

讓我們嘗試啟動伺服器，只是為了好玩

[root@hostname ~]# service mysqld start
Redirecting to /bin/systemctl start  mysqld.service
Failed to issue method call: Unit mysqld.service failed to load: No such file or directory.
[root@hostname ~]# mysqld
-bash: mysqld: command not found
[root@hostname ~]# mysql.server start
-bash: mysql.server: command not found
[root@hostname ~]# 

這就是我迷路的地方。查看實際安裝的內容，沒有伺服器/守護程序

有人願意指出我在這裡做錯了什麼嗎？

如果有人偶然發現這一點，我在這裡找到了解決方案：https ://ask.fedoraproject.org/en/question/43459/how-to-start-mysql-mysql-isnt-starting/

要在 Fedora 20 上啟動 MariaDB，請執行以下命令：

systemctl start mariadb.service

要在 Fedora 20 上自動啟動 MariaDB，請執行以下命令：

systemctl enable mariadb.service

啟動 MariaDB 後（僅執行一次），執行以下命令：

/usr/bin/mysql_secure_installation

當你執行時：

yum install mysql

命令預設安裝 MariaDB 而不是 MySQL。

所以試試下面的命令：

yum list installed | grep mariadb

如果mariadb-server失去，請嘗試以下命令：

yum install mariadb-server

它安裝伺服器包然後啟動服務：

systemctl start mariadb

或者：

service mariadb start

我的問題就這樣解決了。
