利用docker安装Nginx以及Nginx常用配置

2019-08-17 本文已影响41人卑微幻想家

首先安装docker-compose，我觉得用起来比较方便。

curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

然后可以在一个你喜欢的目录下，创建docker-compose.yml文件。我是在/use/local/docker/nginx/下创建的。

docker-compose.yml

version: '3.1'
services:
  nginx:
    restart: always
    image: nginx
    container_name: nginx
    ports:
      - 81:80
    volumes:
      - ./conf/nginx.conf:/etc/nginx/nginx.conf
      - ./wwwroot:/usr/share/nginx/wwwroot

注：在创建./conf 目录下创建nginx.conf文件，在./wwwroot下创建 html80文件夹

nginx.conf配置内容

a. 基于端口的虚拟主机

worker_processes  1;

events {
    worker_connections  1024;
}

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

    sendfile        on;
    
    keepalive_timeout  65;
    # 配置虚拟主机 192.168.75.145
    server {
 # 监听的ip和端口，配置 192.168.75.145:80
        listen       80;
 # 虚拟主机名称这里配置ip地址
        server_name  192.168.75.145;
 # 所有的请求都以 / 开始，所有的请求都可以匹配此 location
        location / {
     # 使用 root 指令指定虚拟主机目录即网页存放目录
     # 比如访问 http://ip/index.html 将找到 /usr/local/docker/nginx/wwwroot/html80/index.html
     # 比如访问 http://ip/item/index.html 将找到 /usr/local/docker/nginx/wwwroot/html80/item/index.html

            root   /usr/share/nginx/wwwroot/html80;
     # 指定欢迎页面，按从左到右顺序查找
            index  index.html index.htm;
        }

    }
    # 配置虚拟主机 192.168.75.245
    server {
        listen       8080;
        server_name  192.168.75.145;

        location / {
            root   /usr/share/nginx/wwwroot/html8080;
            index  index.html index.htm;
        }
    }
}

b. 基于域名的虚拟主机

user  nginx;
worker_processes  1;

events {
    worker_connections  1024;
}

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

    sendfile        on;

    keepalive_timeout  65;
    server {
        listen       80;
        server_name  admin.service.itoken.funtl.com;
        location / {
            root   /usr/share/nginx/wwwroot/htmlservice;
            index  index.html index.htm;
        }

    }

    server {
        listen       80;
        server_name  admin.web.itoken.funtl.com;

        location / {
            root   /usr/share/nginx/wwwroot/htmlweb;
            index  index.html index.htm;
        }
    }
}

c. 反向代理

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 80;
     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 80;
     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;
     }
 }
}

注意：新版 Nginx 的 upstream 配置中的名称不可以有下划线("_")，否则会报 400 错误

d.负载均衡

user  nginx;
worker_processes  1;

events {
    worker_connections  1024;
}

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

    sendfile        on;

    keepalive_timeout  65;
 
 upstream myapp1 {
     server 192.168.75.145:9090 weight=10;
     server 192.168.75.145:9091 weight=10;
 }

 server {
     listen 80;
     server_name nginx.funtl.com;
     location / {
         proxy_pass http://myapp1;
         index index.jsp index.html index.htm;
     }
 }
}
