nginx反向代理多个系统

1、思路：根据不同的URL去跳转到不同的系统中

2、分析：

$request_uri代表的是URL地址除去“http://域名”字符串以后剩下的字符串，例如：URL地址为：

http://192.154.222.191:8000/itoo-basic-majorchoosecourse-web/settingMajorCourse

，则$request_uri代表的是itoo-basic-majorchoosecourse-web/settingMajorCourse这个字符串。

根据if判断语句进入到不同系统。

$request_uri ~ "^\/itoo-basic"：开头是”/itoo-basic”的进入basic_server。

$request_uri ~"^\/itoo-authority"：开头是”/itoo- authority”的进入authority _server。

3、配置

如果再添加一个系统，只要在nginx.conf配置文件中再添加upstream和if语句，例如再添加一个新生，则可以写：

upstream freshmen _server {

server ip：端口

}

if ( $request_uri ~ "^\/ itoo-freshmen" )

{

proxy_pass http:// freshmen _server;

}

完整的反向代理的配置文件：

nginx.conf

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;     source_charset GB2312;     server_names_hash_bucket_size 256;     client_header_buffer_size 256k;     large_client_header_buffers 4 256k;     #size limits     client_max_body_size             50m;     client_body_buffer_size        256k;     client_header_timeout     3m;     client_body_timeout 3m;     send_timeout             3m;#参数都有所调整.目的是解决代理过程中出现的一些502 499错误          sendfile on;     tcp_nopush         on;     keepalive_timeout 120; #参数加大,以解决做代理时502错误     tcp_nodelay on;    #gzip  on;    include /etc/nginx/conf.d/*.conf;    include  /etc/nginx/upstream.conf;    include  /etc/nginx/server.conf; }

upstream.conf

    upstream tomcat_server {server IP地址:端口;    }        upstream authority_server {        server IP地址：端口;    }

upstream.conf

server     {            listen             8088;            server_name    192.168.22.160;            charset GB2312;            index index.html index.htm;            root    /date/wwwroot/linuxtone/;                location ~ ^/NginxStatus/ {                        stub_status on;                        access_log off;                 }         location / {             root    /date/wwwroot/linuxtone/;             proxy_redirect off ;             proxy_set_header Host $host;             proxy_set_header X-Real-IP $remote_addr;             proxy_set_header REMOTE-HOST $remote_addr;             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;             client_max_body_size 50m;             client_body_buffer_size 256k;             proxy_connect_timeout 30;             proxy_send_timeout 30;             proxy_read_timeout 60;             proxy_buffer_size 256k;             proxy_buffers 4 256k;             proxy_busy_buffers_size 256k;             proxy_temp_file_write_size 256k;             proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;             proxy_max_temp_file_size 128m;if ( $request_uri ~ "^\/itoo-basic" ){proxy_pass   http://tomcat_server;}if ( $request_uri ~ "^\/itoo-authority" ){proxy_pass   http://authority_server;}                         }#Add expires header for static content     location ~* \.(jpg|jpeg|gif|png|swf)$ {         if (-f $request_filename) {             root /date/wwwroot/linuxtone/;             expires            1d;             break;            }     }    }

其实这三个配置文件可以写在一个配置文件中，为了看着结构清晰，写在三个文件中。

4、其它办法

有一种思路，nginx的rewrite功能，感觉它能实现，正在研究中。
