1、安装docker

yum -y install docker systemctl start docker systemctl enable docker

安装docker-compose

git clone https://github.com/docker/compose.git chmod u+x compose ./compose or pip install docker-compose docker-compose -version

2、安装mysql

拉取镜像

docker pull mysql

运行MySQL

docker run -p 3306:3306 --name mysql_test -v $PWD/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=passwd -d --privileged=true mysql

命令说明

-p 3306:3306：将容器的3306端口映射到主机的3306端口-v PWD/mysql/data:/var/lib/mysql：将主机当前目录下的mysql/data文件夹挂载到容器的/var/lib/mysql 下，在mysql容器中产生的数据就会保存在本机mysql/data目录下-e MYSQL_ROOT_PASSWORD=passwd：初始化root用户的密码-d 后台运行容器--name 给容器指定别名--privileged=true centos7 可能会碰到权限问题，需要加参数

进入容器

docker exec -it mysql_test /bin/bash

进入数据库查看

root@39e0abed7609:/# mysql -u root -pEnter password: Welcome to the MySQL monitor.

3、安装PHP

vim Dockerfile FROM  php:5.6-fpm RUN apt-get update && apt-get install -y \ libfreetype6-dev \ libjpeg62-turbo-dev \ libpng12*-dev \ vim \ && docker-php-ext-install pdo_mysql \ && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \ && docker-php-ext-install gd \

构造镜像 docker build -t="php-fpm5.6/v2" .

使用该镜像启动容器

docker run -d -p 9000:9000 -v /var/www/html/:/var/www/html/ --name php-with-mysql --link mysql_test:mysql  --volumes-from mysql_test --privileged=true php-fpm5.6/v2

参数解析 －v 将本地磁盘上的php代码挂载到docker 环境中，对应docker的目录是 /var/www/html/ --name 新建的容器名称 php-with-mysql--link 链接的容器，链接的容器名称：在该容器中的别名，运行这个容器是，docker中会自动添加一个host识别被链接的容器ip--privileged=true 权限问题

进入容器

docker exec -it php-with-mysql /bin/bash cd /var/www/html/ && ls

4、安装nginx 镜像

vim default.conf

server {        listen       80;        server_name  localhost;            location / {            root   /var/www/html;            index  index.html index.htm index.php; # 增加index.php        }            #error_page  404              /404.html;            # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   /var/www/html;        }        location ~ \.php$ {            root           /var/www/html; # 代码目录            fastcgi_pass   phpfpm:9000;    # 修改为phpfpm容器            fastcgi_index  index.php;            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; # 修改为$document_root            include        fastcgi_params;        }    }

运行容器

docker run -d --link php-with-mysql:phpfpm --volumes-from php-with-mysql -p 80:80 -v /var/www/nginx/conf/default.conf:/etc/nginx/conf.d/default.conf --name nginx-php --privileged=true  nginx

参数解析

--link php-with-mysql:phpfpm 将php容器链接到nginx容器里来，phpfpm是nginx容器里的别名。--volumes-from php-with-mysql 将php-with-mysql 容器挂载的文件也同样挂载到nginx容器中-v /var/www/nginx/conf/default.conf:/etc/nginx/conf.d/default.conf  将nginx 的配置文件替换，挂载本地编写的配置文件docker exec -it nginx-php bashroot@32de01dbee49:/# cd /var/www/html/&&lsindex.php  mysql.php  testmysql.php  webview

docker-compose
