今天小编跟大家讲解下有关科技常识：详解mac下通过docker搭建LEMP环境，相信小伙伴们对这个话题应该也很关注吧，小编也收集到了有关科技常识：详解mac下通过docker搭建LEMP环境的相关资料，希望小伙伴会喜欢也能够帮助大家。
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 boot2docker3.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 && nginxdefault 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="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
