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 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
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 ## . ## ## ## == ## ## ## ## === /""""""""""""""""/___/ === ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ / ===- ~~~ /______ o __/ / / __/ /____/______/ _ _ ____ _ _| |__ ___ ___ | |_|___ / __| | ___ ___| | _____ _ __| '_ / / _ / / _ /| __| __) / _` |/ _ / / __| |/ / _ / '__|| |_) | (_) | (_) | |_ / __/ (_| | (_) | (__| < __/ ||_.__/ /___/ /___/ /__|_____/__,_|/___/ /___|_|/_/___|_| boot2docker with VirtualBox guest additions version 4.3.14boot2docker: 1.2.0 master : e75396e - Fri Aug 22 06:03:48 UTC 2014docker@boot2docker:~$這樣我們就成功登錄virtualbox中的host環境，便可以進行docker操作了
安裝nginx，php，mysql，基于ubuntu14:04，以下我是通過Dockerfile安裝的
這里是DockFile
6.生成mysql鏡像
Dockerfile
# LEMP stack as a docker containerFROM ubuntu:14.04MAINTAINER Daniel Watrous <email>#ENV http_proxy http://proxy.example.com:8080#ENV https_proxy https://proxy.example.com:8080 RUN apt-get updateRUN apt-get -y upgrade# seed database passwordCOPY mysqlpwdseed /root/mysqlpwdseedRUN debconf-set-selections /root/mysqlpwdseed RUN apt-get -y install mysql-server RUN sed -i -e"s/^bind-address/s*=/s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf RUN /usr/sbin/mysqld & / sleep 10s &&/ echo "GRANT ALL ON *.* TO admin@'%' IDENTIFIED BY 'secret' WITH GRANT OPTION; FLUSH PRIVILEGES" | mysql -u root --password=secret &&/ echo "create database test" | mysql -u root --password=secret # persistence: http://txt.fliglio.com/2013/11/creating-a-mysql-docker-container/ EXPOSE 3306 CMD ["/usr/bin/mysqld_safe"]
mysqlpwdseed
mysql-server mysql-server/root_password password secretmysql-server mysql-server/root_password_again password secret
進入mysql的Dockefile然后生成一個mysql鏡像
docker build -t "local/mysql:v1" .
成功后用
docker images
查看已生成的鏡像
運行mysql鏡像，生成一個容器
docker run -d --name mysql local/mysql:v1
運行起來后，可以用
boot2docker:~$ docker 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
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 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)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }}wall.php 一個用來測試連接mysql的測試文件
<?php // database credentials (defined in group_vars/all)$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="Post to wall"></form>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 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
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 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 mysqldocker 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 mysqldbdocker 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
