nginx proxy_pass配置及关于setcookie的一点说明

作者：zhanhailiang 日期：2015-02-01

nginx proxy_pass配置透传hd域的动态请求到wapi域下：

server {
    listen       80;
    server_name  hd.coalaawork.com;

    access_log  logs/hd.coalaawork.com.access.log;

    root    /usr/local/wwwroot/coalaawork/hd;

    location / {
        index   index.html index.htm index.php;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    location ~* ^.+/.(js|css|gif|png|jpg|bmp|jpeg|htm|xml|swf|json|ico)$ {
        expires off;
        break;
    }

    location /cgi/ {
        proxy_pass http://wapi.coalaawork.com/;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

server {
    listen       80;
    server_name  wapi.coalaawork.com;

    access_log  logs/wapi.coalaawork.com.access.log;

    root    /usr/local/wwwroot/coalaawork/wapi;

    location / {
        index   index.html index.htm index.php;
    }

    if (!-f $request_filename) {
        rewrite ^/(.*)$ /index.php?s=$1 last;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    location ~* ^.+/.(js|css|gif|png|jpg|bmp|jpeg|htm|xml|swf|json|ico)$ {
        expires off;
        break;
    }

    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

说明：

以上配置将匹配hd域下的/cgi/请求，转发到wapi域。注意proxy_pass http://wapi.coalaawork.com/最后的request_uri为/，详细测试用例请见nginx proxy_pass末尾神奇的/

转到时需要带上客户端的IP地址，需要配置：

proxy_set_header  X-Real-IP        $remote_addr;
proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;

使用nginx -t发现“host not found in upstream "wapi.coalaawork.com"”，需要在/etc/hosts添加“127.0.0.1 wapi.coalaawork.com”：

[root@/usr/local/nginx/conf/vhosts]# /usr/local/nginx/sbin/nginx -t
nginx: [emerg] host not found in upstream "wapi.coalaawork.com" in /usr/local/nginx/conf/vhosts/coalaawork.com:24
configuration file /usr/local/tengine-2.0.3/conf/nginx.conf test failed

测试如下：

[root@/usr/local/wwwroot/coalaawork]# find .
.
./wapi
./wapi/index.php
./hd

[root@/usr/local/wwwroot/coalaawork]# cat ./wapi/index.php 
<?php

echo json_encode($_SERVER);

setcookie设置$domain参数的三种区别

测试脚本如下：

[root@/usr/local/wwwroot/coalaawork/wapi]# cat index.php 
<?php

setcookie('test1', 1, 0);
setcookie('test2', 2, 0, 'wapi.coalaawork.com');
setcookie('test3', 3, 0, 'hd.coalaawork.com');
echo json_encode($_SERVER);

测试结果如下：

测试结果表明使用setcookie设置cookie时：
1. 默认不设置domain参数时，Set-Cookie时浏览器会在当前域下种下cookie；
2. 当设置domain参数时，Set-Cookie时浏览器在所有的domain子域名下都会带上该cookie(请见php setcookie函数domain参数说明)；
3. Set-Cookie不允许跨域；
