到docker hub的官網去搜索linode/lamp這個映象,可以檢視到他的具體使用說明（檢視具體使用說明，避免走彎路）

建立docker卷
[[email protected] ~]# docker volume create lamp_www
[[email protected] ~]# docker volume create lamp_apache_conf
[[email protected] ~]# docker volume create lamp_mysql_conf
[[email protected] ~]# docker volume create lamp_mysql_data
在宿主機建立 /var/lib/docker/volumes目錄
[[email protected] ~]# mkdir /var/lib/docker/volumes
啟動映象
[[email protected] ~]# docker run -it -p 80:80 -p 3306:3306 -v lamp_www:/var/www -v lamp_apache_conf:/etc/apache2 -v lamp_mysql_conf:/etc/mysql -v lamp_mysql_data:/var/lib/mysql --name lamp linode/lamp /bin/bash
(docker run：執行一個container，如果後面要繫結宿主主機的0-1024埠需要使用sudo，因為是Ubuntu)
( -p port1:port2: 將宿主機的埠port1對映到容器中的port2)
(-v volume:path: 將宿主機的docker卷對映到容器中的指定的路徑)
( -t -i linode/lamp /bin/bash：使用linode/lamp生成容器，並開啟shell)
現在已經進入到了容器內。如果想退出容器,請不要使用exit或ctrl+d.這樣會將容器直接關閉.
退出請使用ctrl + p ,然後 ctrl + q
上面的啟動命令中一共映射了四個路徑，分別是apache的web根目錄，apache和MySQL的兩個主配置檔案，及MySQL的資料目錄.這些都是為了方便我們後續直接在宿主機上對配置檔案和web檔案的修改進行的操作,利用docker卷映射了資料庫的目錄也能保證映象再次執行的時候資料不會丟失.

drwxr-xr-x. 3 root root 19 Dec 1 13:41 lamp_www
進入lamp_mysql_data這個卷的目錄,可以看到映象中的資料庫目錄已經對映到宿主機裡了. 這個卷只要不刪除,其資料就一直存在其中.這樣避免了映象重啟後資料丟失的情況.

在終端中對lamp環境作個性化配置
[[email protected] ~]# docker exec -i -t lamp bash
啟動apache2和mysql
[email protected]:/#service apache2 start
[email protected]:/#service mysql start
( 可以通過netstat -naltp 命令檢視80和3306埠有沒有開啟成功)
[email protected]:/# netstat -naltp

設定mysql允許root遠端登入,及設定root的密碼
[email protected]:/#smysql -u root -p

安裝php擴充套件
[email protected]980e:/# apt-get update
[email protected]:/# apt-get install -y php5-mysql
[email protected]:/# apt-get install -y php5-gd
#然後重啟apache2:
[email protected]:/# service apache2 restart
#再次確認mysql和apache2有沒有安裝成功：
