在mac下通過docker搭建LEMP環境境

1.安裝virtualbox。由于docker是在lxc環境的容器

2.安裝boot2docker，用于與docker客戶端通訊

> brew update

> brew install docker

> brew install boot2docker

3.初始化boot2docker，也就是在virtualbox上安裝一個docker的host環境

boot2docker init

此時會下載一個鏡像

4.啟動虛擬機host

:~$ boot2docker up

Waiting for VM and Docker daemon to start...

....................ooo

Started.

To connect the Docker client to the Docker daemon, please set:

export DOCKER_HOST=tcp://192.168.59.103:2375

unset DOCKER_CERT_PATH

這樣host環境就啟動起來了，根據提示設置環境變量

export DOCKER_HOST=tcp://192.168.59.103:2375

后boot2docker就能與host環境的docker客戶端連接了

5.連接host環境的docker客戶端

MacBook-Pro:~$ boot2docker ssh

boot2docker with VirtualBox guest additions version 4.3.14

boot2docker: 1.2.0

master : e75396e - Fri Aug 22 06:03:48 UTC 2014

docker@boot2docker:~$

這樣我們就成功登錄virtualbox中的host環境，便可以進行docker操作了

安裝nginx，php，mysql，基于ubuntu14:04，以下我是通過Dockerfile安裝的

6.生成mysql鏡像

Dockerfile

# LEMP stack as a docker container

FROM ubuntu:14.04

MAINTAINER Daniel Watrous

#ENV http_proxy http://proxy.example.com:8080

#ENV https_proxy https://proxy.example.com:8080

RUN apt-get update

RUN apt-get -y upgrade

# seed database password

COPY mysqlpwdseed /root/mysqlpwdseed

RUN debconf-set-selections /root/mysqlpwdseed

RUN apt-get -y install mysql-server

RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf

RUN /usr/sbin/mysqld & \

sleep 10s &&\

echo "GRANT ALL ON *.* TO admin@'%' IDENTIFIED BY 'secret' WITH GRANT OPTION; FLUSH PRIVILEGES" | mysql -u root --password=secret &&\

echo "create database test" | mysql -u root --password=secret

# persistence: http://txt.fliglio.com/2013/11/creating-a-mysql-docker-container/

EXPOSE 3306

CMD ["/usr/bin/mysqld_safe"]

mysqlpwdseed

mysql-server mysql-server/root_password password secret

mysql-server mysql-server/root_password_again password secret

進入mysql的Dockefile然后生成一個mysql鏡像

docker build -t "local/mysql:v1" .

成功后用

docker images

查看已生成的鏡像

運行mysql鏡像，生成一個容器

docker run -d --name mysql local/mysql:v1

運行起來后，可以用

boot2docker:~$ docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

c2332dcad7ca local/mysql:v1 "/usr/bin/mysqld_saf 26 hours ago Up 2 seconds 3306/tcp mysql,nginx/mysql

來查看正在運行的容器

7.生成nginx，php ，這兩個用一個dockerfile生成一個鏡像

dockerfile

# LEMP stack as a docker container

FROM ubuntu:14.04

MAINTAINER Daniel Watrous

ENV http_proxy http://proxy.example.com:8080

ENV https_proxy https://proxy.example.com:8080

# install nginx

RUN apt-get update

RUN apt-get -y upgrade

RUN apt-get -y install nginx

RUN echo "daemon off;" >> /etc/nginx/nginx.conf

RUN mv /etc/nginx/sites-available/default /etc/nginx/sites-available/default.bak

COPY default /etc/nginx/sites-available/default

# install PHP

RUN apt-get -y install php5-fpm php5-mysql

RUN sed -i s/\;cgi\.fix_pathinfo\s*\=\s*1/cgi.fix_pathinfo\=0/ /etc/php5/fpm/php.ini

# prepare php test scripts

RUN echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/info.php

ADD wall.php /usr/share/nginx/html/wall.php

# add volumes for debug and file manipulation

VOLUME ["/var/log/", "/usr/share/nginx/html/"]

EXPOSE 80

CMD service php5-fpm start && nginx

default 一個默認的nginx配置文件

server {

listen 80 default_server;

listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;

index index.php index.html index.htm;

server_name localhost;

location / {

try_files $uri $uri/ =404;

}

error_page 404 /404.html;

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /usr/share/nginx/html;

}

location ~ \.php$ {

fastcgi_split_path_info ^(.+\.php)(/.+)$;

fastcgi_pass unix:/var/run/php5-fpm.sock;

fastcgi_index index.php;

include fastcgi_params;

}

}

wall.php 一個用來測試連接mysql的測試文件

// database credentials (defined in group_vars/all)

$dbname = "test";

$dbuser = "admin";

$dbpass = "secret";

$dbhost = "mysql";

// query templates

$create_table = "CREATE TABLE IF NOT EXISTS `wall` (

`id` int(11) unsigned NOT NULL auto_increment,

`title` varchar(255) NOT NULL default '',

`content` text NOT NULL default '',

PRIMARY KEY (`id`)

) ENGINE=MyISAM DEFAULT CHARSET=utf8";

$select_wall = 'SELECT * FROM wall';

// Connect to and select database

$link = mysql_connect($dbhost, $dbuser, $dbpass)

or die('Could not connect: ' . mysql_error());

echo "Connected successfully\n
\n";

mysql_select_db($dbname) or die('Could not select database');

// create table

$result = mysql_query($create_table) or die('Create Table failed: ' . mysql_error());

// handle new wall posts

if (isset($_POST["title"])) {

$result = mysql_query("insert into wall (title, content) values ('".$_POST["title"]."', '".$_POST["content"]."')") or die('Create Table failed: ' . mysql_error());

}

// Performing SQL query

$result = mysql_query($select_wall) or die('Query failed: ' . mysql_error());

// Printing results in HTML

echo "

while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {

echo "\t

\n";

foreach ($line as $col_value) {

echo "\t\t

$col_value\n";

}

echo "\t

\n";

}

echo "

\n";

// Free resultset

mysql_free_result($result);

// Closing connection

mysql_close($link);

?>

Title:

Message:

把這三個文件放在同一目錄

進入目錄

利用dockerfile生成鏡像

docker build -t "local/nginx:v1" .

生成成功后查看句是你

boot2docker:~$ docker images

REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE

local/nginx v1 9489872e2ebb 25 hours ago 250 MB

local/mysql v1 b70d2e0f7f9c 26 hours ago 351.1 MB

ubuntu 14.04 9bd07e480c5b 3 days ago 192.7 MB

運行

docker run -d -p 80:80 --link mysql:mysql --name nginx local/nginx:v1

這時通過查看正在運行的容器

boot2docker:~$ docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

52e430b58579 local/nginx:v1 "/bin/sh -c 'service 21 hours ago Up 3 seconds 0.0.0.0:80->80/tcp nginx

c2332dcad7ca local/mysql:v1 "/usr/bin/mysqld_saf 26 hours ago Up 11 minutes 3306/tcp mysql,nginx/mysql

就可以看到nginx和mysql兩個運行中的容器，其中nginx通過link連接到了mysql容器，

通過

--link mysql:mysql

命令，把mysql容器的地址加入到了nginx父容器的host文件中，此后，通過訪問別名mysql，就可以訪問到數據庫了。

瀏覽器訪問：192.168.59.103/wall.php，就可訪問剛搭好的web服務器

8.持載目錄到容器中

我們希望持載一個本地目錄到容器中，以后存放可能需要修改的web內容，這里我們通過

-v /Users/lyc/web:/usr/share/nginx/html

把的本地目錄到容器中，存放web目錄內容，這樣就可以把wall.php之類的web文件放在/Users/lyc/web目錄，供容器訪問

但是因為mac環境下host主機為virtualbox，因此我們先要綁定mac下的目錄到虛擬機中

首先停止boot2docker

> boot2docker down

然后

> curl http://static.dockerfiles.io/boot2docker-v1.2.0-virtualbox-guest-additions-v4.3.14.iso > ~/.boot2docker/boot2docker.iso

> VBoxManage sharedfolder add boot2docker-vm -name home -hostpath /Users

> boot2docker up

重新連docker后

先刪除原先停止的容器

docker rm mysql

docker rm nginx

啟動容器時掛載我們的目錄到nginx的目錄中

docker run -d -p 3306:3306 --name mysql mysqldb

docker run -d -p 80:80 -v /Users/lyc/web:/usr/share/nginx/html --link mysql:mysql --name nginx local/nginx:v1

這樣就可以修改/Users/lyc/web中的內容來更新/usr/share/nginx/html了
