docker-compose部署nginx

1、配置文件和挂载目录

mkdir -p /home/volumes/nginx/conf
docker run -itd --name nginx -p 80:80  nginx
docker cp nginx:/etc/nginx/nginx.conf /home/volumes/nginx/conf/
docker cp nginx:/etc/nginx/conf.d /home/volumes/nginx/
docker cp nginx:/usr/share/nginx/html /home/volumes/nginx/
docker stop nginx && docker rm nginx

2、配置文件

这里将主配置文件和其他配置文件分开配置，如果要代理新的服务，只需要在conf.d文件目录下添加新的配置文件，然后重启nginx就可以了
nginx.conf 主配置文件所在目录：/home/volumes/nginx/conf/
加载conf.d文件夹下的配置文件：include /etc/nginx/conf.d/*.conf;
nginx.conf配置文件：

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;
    # 将分离的配置文件加载进来
    include /etc/nginx/conf.d/*.conf;
}

分离的配置文件目录：/home/volumes/nginx/conf.d/ 该目录下的文件都是以.conf结尾的配置项。
以pontainer为例：pontainer.conf

# nginx负载均衡  upstream 服务名
upstream pontainer{
   # 服务ip和端口
   server 192.168.1.5:9000;
}

server {
    
    listen 80;
    charset utf-8;
    # 访问域名
    server_name pontainer.db.com.cn;
    client_max_body_size 50m;
    

    location / {
        #反向代理地址
        proxy_pass   http://pontainer;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    #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;
    }
}

3、nginx部署文件

启动：docker-compose -f nginx-compose.yaml up -d
停止：docker-compose -f nginx-compose.yaml down

version: "3"
services:
  nginx:
    container_name: nginx
    image: nginx:latest
    restart: always
    ports:
      - "80:80"
    volumes:
      - "/home/volumes/nginx/conf/nginx.conf:/etc/nginx/nginx.conf"
      - "/home/volumes/nginx/conf.d:/etc/nginx/conf.d"
      - "/home/volumes/nginx/log:/var/log/nginx"
      - "/home/volumes/nginx/html:/usr/share/nginx/html"
