用 Docker 运行 Nginx 容器做域名反向代理

1首先pull下载nginx镜像包

docker pull nginx 

2（关键）查看nginx镜像里面配置文件、日志等文件的具体位置，只有找到镜像配置文件的路径，后面挂载文件和文件夹才能覆盖这些路径

3  以终端的方式打开镜像容器

docker run -i -t nginx /bin/bash

3 创建目录

mkdir   root/nginx/conf

mkdir   root/nginx/logs

mkdir   root/nginx/conf.d

mkdir   root/nginx/www

4 copy nginx.conf，  default.conf，  html文件夹  到服务器上

① 修改服务器上的/root/ngnx/conf.d/default.conf ,把首页改为1.html

 

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  1.html;
    }

    #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   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

②  1.html 注意中文乱码  我的是在本地改为ansi 编码后  再上传到服务器上

h1>反向代理 哇咔咔1.html!
Welcome to nginx!

working. Further configuration is required.

Thank you for using nginx.

 ③  在服务器上的/root/ngnx/conf.d/ 目录下创建  www.ygksfp.com.conf   宿主机IP改为自己的服务器IP

[root@iz2zeanknh3pufmfwttc47z conf.d]# vi www.ygksfp.com.conf
[root@iz2zeanknh3pufmfwttc47z conf.d]# cat www.ygksfp.com.conf 
server {
    listen  80;
    server_name  www.if404.com;
    access_log /var/log/nginx/if404.access.log main;
    error_log /var/log/nginx/if404.error.log error;
    location / {
        proxy_set_header  Host  $http_host;
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass  http://宿主机IP:8080;
    }
}

 6  现在创建容器并挂载文件

docker run  -d -p 80:80 --name mynginx  
-v /root/nginx/www:/usr/share/nginx/html 
-v /root/nginx/conf/nginx.conf:/etc/nginx/nginx.conf 
-v /root/nginx/conf.d:/etc/nginx/conf.d  
-v /root/nginx/logs:/var/log/nginx 
nginx

注意  服务器上的文件或者文件夹必须要存在  不然就会报错

如果没有启动成功要先用docker ps -a查看失败的容器，并且用docker rm CONTAILNER ID删除容器ID，再查找问题，然后docker run再启动容器，如果在确保挂载的目录和文件没有问题还是不能启动的话，那么就是权限问题了，网上说的就是在docker run后面加个 --privileged=true参数

7  使用IP ：访问首页

如何在本地配置域名：

使用域名访问首页

 我的域名还没备案打开暂时是这个效果，反向代理是成功了的
