用Docker解决坑爹的环境搭建系列——lamp(php5+mysql+apache2)

1. 下载适合镜像

首先在docker hub中搜索lamp

docker search lamplocalhost:~ yangyue$ docker search lampNAME                                   DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDlinode/lamp                            LAMP on Ubuntu 14.04.1 LTS Container            110...

这里我们就选择星级最高的linode/lamp，pull镜像：

docker pull linode/lamp

如果你不知道怎么使用这个镜像，或者这个镜像里面的初始配置，那么你可以在

https://hub.docker.com/

中搜索这个镜像，然后查看官方说明。

2. 启动此镜像

根据官方镜像说明，我们启动命令如下：

sudo docker run -p 80:80 -p 3306:3306 -v /your/path/www:/var/www -v /your/path/apache2.conf:/etc/apache2/apache2.conf -v /your/path/my.cnf:/etc/mysql/my.cnf -t -i linode/lamp /bin/bash#解释：docker run：运行一个container，如果后面要绑定宿主主机的0-1024端口需要使用sudo-p port1:port2: 将宿主机的端口port1映射到容器中的port2-v file1:file2: 将宿主机的文件\路径挂载到容器中的文件\路径-t -i linode/lamp /bin/bash：使用linode/lamp生成容器，并打开shell

上面的启动命令中一共映射了三个路径，分别是apache2的web根目录，Apache和mysql的两个主配置文件，都是为了方便我们后续直接在宿主机上对配置文件和web文件的修改，当然你也可以通过容器的shell进行修改，但是这样需要在容器中安装vim，而且这样也改变了基础镜像，个人感觉不太好。

分别在你映射的宿主主机目录（/your/path）中建立相应的文件和目录：

2.1 mysql配置文件my.cnf

见文末

2.2 apache配置文件apache2.conf

见文末

2.3 www目录

按照官方的说明，在你的www目录下应该有下面这些目录：

example.comexample.com/public_html #web根目录example.com/logexample.com/backups

2.4 我的配置：

首先说下我的启动命令：

sudo docker run -p 80:80 -p 3336:3306 -v /Users/yangyue/docker/lamp/www:/var/www -v /Users/yangyue/docker/lamp/apache-conf/apache2.conf:/etc/apache2/apache2.conf -v /Users/yangyue/docker/lamp/mysql-conf/my.cnf:/etc/mysql/my.cnf -t -i linode/lamp /bin/bash

我的宿主机路径配置：

/Users/yangyue/docker/lamp/├── apache-conf│   └── apache2.conf├── mysql-conf│   └── my.cnf└── www    └── example.com        ├── backups        ├── log        └── public_html

3. 在终端中对lamp环境作个性化配置

虽然配置文件等可以从宿主机进行挂载，但是mysql的权限配置、php的扩展等还是需要我们根据自己的需求进行配置。

3.1 启动apache2和mysql

service apache2 startservice mysql start# 可以通过netstat -pant 命令查看80和3306端口有没有开启成功

由于该镜像不允许root远程登录，所以修改密码等，我们需要在container中的shell中进行，配置mysql：

mysql -uroot -p#密码：Admin2015#修改root可远程登录：mysql>use mysql;mysql>update user set host = '%' where user = 'root' and host='127.0.0.1';#修改密码：mysql>update user set password=password("your_password");#刷新权限FLUSH PRIVILEGES;

通过上面的操作，你应该可以在容器之外访问mysql了

3.2 安装你想要的php扩展

apt-get updateapt-get install php5-mysqlapt-get install php5-gd...#然后重启apache2:service apache2 restart#再次确认mysql和apache2有没有安装成功：netstat -pant

至此，lamp环境就搭建完成了。我们通过：

ctrl + pctrl + q

退出shell，在shipyard看到我们的容器情况：

Apache: apache2.conf

# This is the main Apache server configuration file.  It contains the# configuration directives that give the server its instructions.# See http://httpd.apache.org/docs/2.4/ for detailed information about# the directives and /usr/share/doc/apache2/README.Debian about Debian specific# hints.### Summary of how the Apache 2 configuration works in Debian:# The Apache 2 web server configuration in Debian is quite different to# upstream's suggested way to configure the web server. This is because Debian's# default Apache2 installation attempts to make adding and removing modules,# virtual hosts, and extra configuration directives as flexible as possible, in# order to make automating the changes and administering the server as easy as# possible.# It is split into several files forming the configuration hierarchy outlined# below, all located in the /etc/apache2/ directory:##   /etc/apache2/#   |-- apache2.conf#   |   `--  ports.conf#   |-- mods-enabled#   |   |-- *.load#   |   `-- *.conf#   |-- conf-enabled#   |   `-- *.conf#   `-- sites-enabled#       `-- *.conf### * apache2.conf is the main configuration file (this file). It puts the pieces#   together by including all remaining configuration files when starting up the#   web server.## * ports.conf is always included from the main configuration file. It is#   supposed to determine listening ports for incoming connections which can be#   customized anytime.## * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/#   directories contain particular configuration snippets which manage modules,#   global configuration fragments, or virtual host configurations,#   respectively.##   They are activated by symlinking available configuration files from their#   respective *-available/ counterparts. These should be managed by using our#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See#   their respective man pages for detailed information.## * The binary is called apache2. Due to the use of environment variables, in#   the default configuration, apache2 needs to be started/stopped with#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not#   work with the default configuration.# Global configuration### ServerRoot: The top of the directory tree under which the server's# configuration, error, and log files are kept.## NOTE!  If you intend to place this on an NFS (or otherwise network)# mounted filesystem then please read the Mutex documentation (available# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);# you will save yourself a lot of trouble.## Do NOT add a slash at the end of the directory path.##ServerRoot "/etc/apache2"## The accept serialization lock file MUST BE STORED ON A LOCAL DISK.#Mutex file:${APACHE_LOCK_DIR} default## PidFile: The file in which the server should record its process# identification number when it starts.# This needs to be set in /etc/apache2/envvars#PidFile ${APACHE_PID_FILE}## Timeout: The number of seconds before receives and sends time out.#Timeout 300## KeepAlive: Whether or not to allow persistent connections (more than# one request per connection).
