mac下通过docker搭建LEMP环境

在mac下通过docker搭建LEMP环境境

1.安装virtualbox。由于docker是在lxc环境的容器

2.安装boot2docker，用于与docker客户端通讯

> brew update> brew install docker> brew install boot2docker

3.初始化boot2docker，也就是在virtualbox上安装一个docker的host环境

 boot2docker init

此时会下载一个镜像

4.启动虚拟机host

:~$ boot2docker upWaiting for VM and Docker daemon to start.......................oooStarted.To connect the Docker client to the Docker daemon, please set:    export DOCKER_HOST=tcp://192.168.59.103:2375    unset DOCKER_CERT_PATH

这样host环境就启动起来了，根据提示设置环境变量

 export DOCKER_HOST=tcp://192.168.59.103:2375

后boot2docker就能与host环境的docker客户端连接了

5.连接host环境的docker客户端

MacBook-Pro:~$ boot2docker ssh                        ##        .                  ## ## ##       ==               ## ## ## ##      ===           /""""""""""""""""\___/ ===      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~           \______ o          __/             \    \        __/              \____\______/ _                 _   ____     _            _| |__   ___   ___ | |_|___ \ __| | ___   ___| | _____ _ __| ‘_ \ / _ \ / _ \| __| __) / _` |/ _ \ / __| |/ / _ \ ‘__|| |_) | (_) | (_) | |_ / __/ (_| | (_) | (__|   <  __/ ||_.__/ \___/ \___/ \__|_____\__,_|\___/ \___|_|\_\___|_|  boot2docker with VirtualBox guest additions version 4.3.14boot2docker: 1.2.0             master : e75396e - Fri Aug 22 06:03:48 UTC 2014docker@boot2docker:~$

这样我们就成功登录virtualbox中的host环境，便可以进行docker操作了

 

安装nginx，php，mysql，基于ubuntu14:04，以下我是通过Dockerfile安装的

这里是DockFile

6.生成mysql镜像

Dockerfile

# LEMP stack as a docker containerFROM ubuntu:14.04MAINTAINER Daniel Watrous <email>#ENV http_proxy http://proxy.example.com:8080#ENV https_proxy https://proxy.example.com:8080 RUN apt-get updateRUN apt-get -y upgrade# seed database passwordCOPY mysqlpwdseed /root/mysqlpwdseedRUN 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 secretmysql-server mysql-server/root_password_again password secret

进入mysql的Dockefile然后生成一个mysql镜像

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

成功后用

docker images

查看已生成的镜像

运行mysql镜像，生成一个容器

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

运行起来后，可以用

boot2docker:~$ docker psCONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS               NAMESc2332dcad7ca        local/mysql:v1      "/usr/bin/mysqld_saf   26 hours ago        Up 2 seconds        3306/tcp            mysql,nginx/mysql

来查看正在运行的容器

7.生成nginx，php ，这两个用一个dockerfile生成一个镜像

dockerfile

# LEMP stack as a docker containerFROM ubuntu:14.04MAINTAINER Daniel Watrous <email>ENV http_proxy http://proxy.example.com:8080ENV https_proxy https://proxy.example.com:8080 # install nginxRUN apt-get updateRUN apt-get -y upgradeRUN apt-get -y install nginxRUN echo "daemon off;" >> /etc/nginx/nginx.confRUN mv /etc/nginx/sites-available/default /etc/nginx/sites-available/default.bakCOPY default /etc/nginx/sites-available/default # install PHPRUN apt-get -y install php5-fpm php5-mysqlRUN sed -i s/\;cgi\.fix_pathinfo\s*\=\s*1/cgi.fix_pathinfo\=0/ /etc/php5/fpm/php.ini # prepare php test scriptsRUN echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/info.phpADD wall.php /usr/share/nginx/html/wall.php # add volumes for debug and file manipulationVOLUME ["/var/log/", "/usr/share/nginx/html/"] EXPOSE 80 CMD service php5-fpm start && nginx

default 一个默认的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 一个用来测试连接mysql的测试文件

<?php // 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, $dbpass)    or die(‘Could not connect: ‘ . mysql_error());echo "Connected successfully\n<br />\n";mysql_select_db($dbname) or die(‘Could not select database‘); // create table$result = mysql_query($create_table) or die(‘Create Table failed: ‘ . mysql_error()); // handle new wall postsif (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($select_wall) or die(‘Query failed: ‘ . mysql_error()); // Printing results in HTMLecho "<table>\n";while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {    echo "\t<tr>\n";    foreach ($line as $col_value) {        echo "\t\t<td>$col_value</td>\n";    }    echo "\t</tr>\n";}echo "</table>\n"; // Free resultsetmysql_free_result($result); // Closing connectionmysql_close($link);?> <form method="post">Title: <input type="text" name="title"><br />Message: <textarea name="content"></textarea><br /><input type="submit" value=http://www.mamicode.com/"Post to wall"></form>

把这三个文件放在同一目录

进入目录

利用dockerfile生成镜像

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

生成成功后查看句是你

boot2docker:~$ docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZElocal/nginx         v1                  9489872e2ebb        25 hours ago        250 MBlocal/mysql         v1                  b70d2e0f7f9c        26 hours ago        351.1 MBubuntu              14.04               9bd07e480c5b        3 days ago          192.7 MB

运行

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

这时通过查看正在运行的容器

boot2docker:~$ docker psCONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS                NAMES52e430b58579        local/nginx:v1      "/bin/sh -c ‘service   21 hours ago        Up 3 seconds        0.0.0.0:80->80/tcp   nginxc2332dcad7ca        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两个运行中的容器，其中nginx通过link连接到了mysql容器，

通过

--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，通过访问别名mysql，就可以访问到数据库了

浏览器访问

192.168.59.103/wall.php

就可访问刚搭好的web服务器

8.持载目录到容器中

我们希望持载一个本地目录到容器中，以后存放可能需要修改的web内容，这里我们通过

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

把的本地目录到容器中，存放web目录内容，这样就可以把wall.php之类的web文件放在

/Users/lyc/web目录，供容器访问

但是因为mac环境下host主机为virtualbox，因此我们先要绑定mac下的目录到虚拟机中

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

 

重新连docker后

先删除原先停止的容器

docker rm mysqldocker rm nginx

 

启动容器时挂载我们的目录到nginx的目录中

docker run -d  -p 3306:3306 --name mysql mysqldbdocker run -d -p 80:80 -v /Users/lyc/web:/usr/share/nginx/html --link mysql:mysql --name nginx local/nginx:v1

这样就可以修改/Users/lyc/web中的内容来更新/usr/share/nginx/html了

 

写得比较匆忙，更多的命令和具体查看
