1.何爲LAMP
linux+mysql+php+apache2的簡稱。我在linux環境下搭建apache2服務器，同時安裝php7,mysql，還有其他依賴的包。我將我以前設計的某個簡單網頁index.html放在/var/www/index目錄後，目錄可在配置文件配置，你有可能是/var/www/html目錄，自己設置，自己開心就好，
sudo /etc/init.d/apache2 restart 開始運行apache2服務，頁面長這個樣子，我是在window去訪問搭建在虛擬機linux下的頁面
2.在目錄www下放置index.php來驗證我的php和mysql安裝成功了與否
index.php內容
<?php
phpinfo();
?>
訪問：ip/index.php
3.phpmyadmin無法安裝的問題
sudo apt-get install phpmyadmin後發現apache2服務自動停止，根本restart不了，將輸出的報錯信息去尋找解決方案也沒知道，後來卸掉phpmyadmin後，apache2又自動可以工作，重新安裝phpmyadmin後apache2又不能工作。但是發現安裝phpmyadmin 時phpmyadmin居然也下了依賴php5相關的包！！！！！！網上沒有找到解決方案，apt-get update也不管用，後來修改了apt源之後就闊以了，驚呆了，我之前修改過源，因爲原來的源太慢了，修改爲阿里源，慶幸我備過份，在此，放一下這個源

然後sudo apt-get update一下，過程比阿里源的比較慢一些，然後 sudo apt-get install phpmyadmin然後apache2依然可以工作，因爲它依賴並下載了php7相關的包了建立軟連接到index目錄下，sudo ln -s /usr/share/phpmyadmin /var/www/index/phpmyadmin,再訪問 你的ip/phpmyadmin 就可以啦
