使用不同的配置文件与网页文件部署nginx容器

本文主要是介绍使用不同的配置文件与网页文件部署nginx容器，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

使用不同的配置文件与网页文件部署nginx容器，这样部署一个容器就能访问不同的网站。

//拉一个之前源码部署nginx的镜像

//创建一个目录来放提出来的文件
[root@localhost ~]# mkdir config
[root@localhost ~]# docker cp  nginx:/usr/local/nginx/conf config/
[root@localhost ~]# docker cp  nginx:/usr/local/nginx/html config/
[root@localhost ~]# ls config/
conf  html

[root@localhost ~]# mkdir config/html/test
[root@localhost ~]# echo "hello world" > html/test/index.html
-bash: html/test/index.html: 没有那个文件或目录
[root@localhost ~]# echo "hello world" > config/html/test/index.html
[root@localhost ~]# ls config/html/test/
index.html


[root@localhost ~]# vim config/conf/nginx.conf
//添加以下行
.....略
 84     server {
 85         listen       8080;
 86         server_name test.example.com;
 87 
 88         location / {
 89             root   html/test;
 90             index  index.html index.htm;
 91            }

启动容器

//映射端口和本地文件
[root@localhost ~]# docker run -itd --name web -v /root/config/html:/usr/local/nginx/html  -v /root/config/conf:/usr/local/nginx/conf -p 8080:8080 -p 80:80 luohengjie/nginx:v1.20.1

以后可以通过直接修改本地文件来创建容器达到快速部署的目的
