022--Docker使用nginx负载场景

2、nginx使用

1、简单使用nginx进行页面访问

2、nginx对网址进行概率性负载

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
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;

    include /etc/nginx/conf.d/*.conf;


    upstream myweb {
        server 192.168.221.128:8090 weight=1;
        server 192.168.221.128:8091 weight=1;
    }

}

3、根据域名进行负载

user  root;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
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;
    include /etc/nginx/conf.d/*.conf;

    #对域名进行负载
    server
      {
        listen 80;
        server_name www.enzo1.com;
        location / {
          proxy_redirect off;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_pass http://192.168.221.133:8081;
        }
      }
    
    server
      {
        listen 80;
        server_name www.enzo2.com;
        location / {
          proxy_redirect off;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_pass http://192.168.221.133:8082;
        }
      }
    #对网址进行权重负载
    upstream myweb {
        server 192.168.221.133:8081 weight=1;
        server 192.168.221.133:8082 weight=1;
    }
}
