Nginx服务器配置反向代理详细说明

Nginx的安装

1、安装pcre库
unzip pcre-8.12.zip
cd pcre-8.12
./configure
make % make install

2、安装 nginx
useradd nginx
tar xf nginx-0.8.53.tar.gz
cd nginx-0.8.53
./configure ?prefix=/home/nginx/nginx --with-http_stub_status_module --with-http_ssl_module
make & make install

3、注意事项
如果使用非root用户启动，会提示警告，可以将该用户赋予sudo权限。
修改配置文件
cd /home/nginx/nginx/conf

vim nginx.conf
输入如下内容
user  nginx nginx;
worker_processes  8;
error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
pid        logs/nginx.pid;
worker_rlimit_nofile 51200;
events {
    use epoll;
    worker_connections  51200;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    tcp_nodelay on;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    fastcgi_buffer_size 64k;
    fastcgi_buffers 4 64k;
    fastcgi_busy_buffers_size 128k;
    fastcgi_temp_file_write_size 128k;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 64k;
    gzip_http_version 1.1;
    gzip_comp_level 2;
    gzip_types  text/plain application/x-Javascript text/css application/xml;
    gzip_vary on;
    client_max_body_size 300m;
client_body_buffer_size 128k;
    proxy_connect_timeout 600;
    proxy_read_timeout 600;
    proxy_send_timeout 600;
    proxy_buffer_size 16k;
    proxy_buffers 4 32k;
    proxy_busy_buffers_size 64k;
    proxy_temp_file_write_size 64k;
    upstream media_pool {
      server 10.2.1.117:8080 weight=1 max_fails=2 fail_timeout=30s;
      server 10.2.1.118:8080 weight=1 max_fails=2 fail_timeout=30s;
    }

以上红色部分为反向代理池，定义后端被代理的服务器地址及端口。
    server {
        listen       8085;#代理服务器监听端口
        server_name  www.server110.com;#代理服务器的名称可以是域名也可以是IP
        #charset koi8-r;
        access_log  logs/media.access.log  main;#定义日志
        location /inteSvr/ { #定义规则，目录
            proxy_pass http://media_pool/inteSvr/; #转发规则
            proxy_set_header Host $host:8085; #跳转头信息
            proxy_set_header X-Forwarded-For $remote_addr;#将真实IP传到后面代理服务器
        }
        }
以上红色部分为定义转发服务器规则。
}

启动、停止、重启
启动 /home/nginx/nginx/bin/nginx.start
#!/bin/bash
/home/nginx/nginx/sbin/nginx -c /home/nginx/nginx/conf/nginx.conf

停止
/home/nginx/nginx/bin/nginx.stop
#!/bin/bash
killall nginx

重启
/home/nginx/nginx/bin/nginx.restart
#!/bin/bash
kill -HUP `cat /home/nginx/nginx/logs/nginx.pid`
