1. 下载适合镜像
首先在docker hub中搜索lamp
docker search lamp
localhost:~ yangyue$ docker search lamp
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
linode/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.com
example.com/public_html #web根目录
example.com/log
example.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 start
service 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 update
apt-get install php5-mysql
apt-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 + p
ctrl + 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). Set to "Off" to deactivate.
#
KeepAlive Off
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5
# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog ${APACHE_LOG_DIR}/error.log
#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#
LogLevel warn
# Include module configuration:

# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.
