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

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 bash root@32de01dbee49:/# cd /var/www/html/&&ls index.php mysql.php testmysql.php webview
