This article introduces to you the actual steps of installing PHP environment with docker. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The following are the actual steps

//没有docker先安装
dockeryum -y install docker  
//启动
docker service docker start 
//拉取php+apache镜像 选择了fauria/lamp   
docker pull fauria/lamp 
//查看本地镜像
docker images
/**
   创建新容器
   -p 端口映射,格式为:主机(宿主)端口:容器端口
   -d 后台运行容器,并返回容器ID
   -v 主机的目录映射到容器的 格式为:主机目录:容器目录(多个可以一直往后加-v)
   使用privileged=true,容器内的root拥有真正的root权限
   最后一个参数使用的镜像名称
 */
 docker run -p 8081:80 -d -v /root/code/server:/var/www/project -v /root/data/apache2/:/etc/apache2/sites-available/ --privileged=true fauria/lamp
//查看运行中的容器
docker ps 
//进入id为2552开头的容器      
docker exec -it 2552 bash 

//配置nginx反向代理
docker pull nginx
//创建nginx容器
docker run -p 80:80 -d -v /root/data/nginx:/etc/nginx/conf.d --privileged=true nginx
//nginx配置文件
server {
    listen    80;
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://172.17.0.1:8081;
   }
}
//修改完重启这个容器,才会生效
//查看所有的容器包括未运行的
docker ps -a
//开启一个容器
docker start a9ad
//重启一个容器
docker restart s3ew
//停止一个容器
docker stop 5d5d
//删除一个容器
docker rm 3ef4
//docker-compose是用于方便管理docker容器的工具,用了会方便一点,不用也没错
//比如,容器已经创建了,但是需要修改挂载盘或开放更多端口,
//这些操作只要更改yml文件,然后重新更新就好
//默认情况下文件命名为docker-compose.yml,进入当前目录下执行docker-compose命令就可以了
curl -L https://github.com/docker/compose/releases/download/1.19.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --verison
touch docker-compose.yml
//docker-compose.yml中内容,注意格式
web1:
  image: 'nginx'
  restart: always
  ports:
      - '80:80'
  volumes:
      - '/root/data/nginx:/etc/nginx/conf.d'web2:
  image: 'fauria/lamp'
  restart: always
  ports:
      - '8081:80'
  volumes:
      - '/root/code/server:/var/www/project'
    - '/root/data/apache2/000-default.conf:/etc/apache2/sites-available/000-default.conf'
    //修改完文件执行这个更新操作  
    docker-compose up -d
