Docker部署Nginx-反向代理

需求说明

两台Tomcat服务通过Nginx反向代理

• Nginx 服务器：192.168.75.145:80
• Tomcat1 服务器：192.168.75.145:9090
• Tomcat2 服务器：192.168.75.145:9091

Tomcat部署

启动 Tomcat 容器

version: '3'
services:
  tomcat1:
    image: tomcat
    container_name: tomcat1
    ports:
      - 9090:8080
  tomcat2:
    image: tomcat
    container_name: tomcat2
    ports:
      - 9091:8080

Nginx部署

准备存储卷

mkdir data conf

准备Nginx配置文件

创建Nginx配置文件: /usr/local/nginx/conf/nginx.conf, 内容如下:

user  nginx;
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
	# 配置一个代理即 tomcat1 服务器
	upstream tomcatServer1 {
		server 192.168.75.145:9090;
	}
	# 配置一个代理即 tomcat2 服务器
	upstream tomcatServer2 {
		server 192.168.75.145:9091;
	}
	# 配置一个虚拟主机
	server {
		listen 81;
		server_name admin.service.itoken.funtl.com;
		location / {
				# 域名 admin.service.itoken.funtl.com 的请求全部转发到 tomcat_server1 即 tomcat1 服务上
				proxy_pass http://tomcatServer1;
				# 欢迎页面，按照从左到右的顺序查找页面
				index index.jsp index.html index.htm;
		}
	}
	server {
		listen 82;
		server_name admin.web.itoken.funtl.com;
		location / {
			# 域名 admin.web.itoken.funtl.com 的请求全部转发到 tomcat_server2 即 tomcat2 服务上
			proxy_pass http://tomcatServer2;
			index index.jsp index.html index.htm;
		}
	}
}

创建docker-compose.yml

创建文件: /usr/local/nginx/docker-compose.yml, 内容如下:

version: '3.1'
services:
  nginx:
    restart: always
    image: nginx
    container_name: nginx
    ports:
      - 81:9090
      - 82:9091
    volumes:
      - ./conf/nginx.conf:/etc/nginx/nginx.conf
      - ./data:/usr/share/nginx/wwwroot
