現在Linux下的軟件越來越好安裝，尤其是在Ubuntu下安裝軟件，更是沒有技巧，只需要在聯網的情況下使用apt-get inatll 即可。在決定安裝MySQL之前，要先確定系統是否已經安裝MySQL。

本文測試版本：Ubuntu 14.04
Hadoop@master:~$ netstat -tap | grep mysql
（並非所有進程都能被檢測到，所有非本用戶的進程信息將不會顯示，如果想看到所有信息，則必須切換到 root 用戶）
由此可以看出系統中並沒有安裝mysql，執行以下命令進行安裝。
hadoop@master:~$ sudo apt-get install mysql-server

您希望繼續執行嗎？ [Y/n]
輸入Y進入到安裝界面，在安裝過程中，會彈出一個界面要求輸入mysql的root的密碼，這裏一定輸入，省得安裝後再設密碼了。
再次輸入密碼：

MySQL Server安裝過程
mysql安裝完成後，我們可以通過netstat -tap|grep mysql來查看系統是否已經有了mysql服務。
出現上面的信息，說明我們安裝mysql成功。
執行以下命令可以查看MySQL的版本：
hadoop@master:~$ mysql -V
mysql Ver 14.14 Distrib 5.5.38, for debian-linux-gnu (i686) using readline 6.3
