基于Dockerfile搭建LNMP环境

准备工作

#关闭防火墙和防护机制
systemctl stop firewalld 
systemctl disable firewalld
setenforce 0

docker network create --subnet=172.18.0.0/16 
--opt "com.docker.network.bridge.name"="docker1"  mynetwork

#设置自定义网络模式，模式为bridge模式，
docker1的ip地址为172.18.0.1，显示的网络名称mynetwork。

docker network ls
#查看使用的网络模式

ifconfig

部署nginx

（容器IP 为 172.18.0.10）

编写Dockerfile文件

mkdir /opt/nginx
cd /opt/nginx/

上传 nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中


#解压wordpress
mkdir /opt/nginx/html
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

vim Dockerfile

FROM centos:7

#ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html/
#上传论坛的包

RUN chmod 777 -R /usr/local/nginx/html/
#给html文件所有权限

EXPOSE 80
EXPOSE 443
#开放80 443 端口

VOLUME ["/usr/local/nginx/html/"]
#挂载目录(相当于将/usr/local/nginx/html目录共享，
会在宿主机上自动生成共享目录，主要目的是为了让容器之间共享这个文件)(视情况可不需要)

ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]
#执行启动nginx命令,并且关闭nginx的后台启动，因为需要它占用前台，让docker不关闭

 配置nginx.conf文件
