折腾一晚vps，给nginx做域名反向代理失败，请教如何正确设置？

502 Bad Gateway

nginx/0.7.61

@momou 因为我刚删掉了vps的hosts中这段：

203.208.45.206 geekiwi.appspot.com

然后就502了。。

自检没有报错？

@momou 刚才代码里没有}闭合，但是加上}闭合之后，还是不行

[root@vps www]# /usr/local/nginx/sbin/nginx -t
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful

依然跳转到探针页面。

贴出我的nginx.conf文件:

@lowstz 端口设置为每个server_name都不同？

不是，我只是测试，80也可以


自己vps上测试了可以

jiyin.it 现在代理设置是OK的~~，不过点用户链接是404，还未完成的站点么？
先许个愿：妹子~~~~~

本地测试，jiyin.it指向127.0.0.1，反代成功：

vps上jiyin.it应指向vps的IP
只是在http {} 两括号之间加上了：
http://gist.github.com/2132139.js

@lowstz 我改动了一下conf文件，然后新加上了你的。结果访问jiyin.it变成一个nginx的欢迎页面了。。。悲催。。。

}

现在变成 Welcome to nginx!了

@lemonda “vps上jiyin.it应指向vps的IP ”
——
请问你是说的hosts？还是nginx.conf里的proxy_pass项?

@paloalto listen 81; 换成 80，我刚才想改81，但是不小心就提交了，
修改之前你现在访问 jiyin.it:81是没有问题的

server {
listen 80;
server_name jiyin.it;
location / {
proxy_redirect off;
proxy_pass http://geekiwi.appspot.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
这样就OK了，
如果listen 81就得用 http://jiyin.it:81/ 来访问了

@paloalto nginx.conf里就是gist的代码那样了，我是本地测试才把127.0.0.1 jiyin.it写到hosts里的，你把jiyin.it指向199.15.116.122已经可以了。

server {
listen 80;
server_name www.jiyin.it;

access_log /var/log/nginx/localhost.access.log;

location / {
proxy_pass http://ghs.google.com;
proxy_set_header Host $host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarder-For $proxy_add_x_forwarded_for;
# root /var/www/nginx-default;
# index index.html index.htm;
}
}

把listen 81改成了listen 80后还是欢迎页面，会不会是nginx.conf里第一个server对第二个server有干扰？

重新帖一遍现在的nginx.conf的内容：

}

现在OK的，CTRL+F5看看？

@paloalto 可以看到基因了，你浏览器多刷新几次，或者关掉重开，或者换一个

@ccdjh 新加的access_log是干嘛的？

[emerg]: open() "/var/log/nginx/localhost.access.log" failed (2: No such file or directory)

@lowstz @aggron 你们那边都可以直接用jiyin.it访问吗？我这边怎么还不行。。。。纠结。。

是的，能直接访问
CTRL+F5，
或者清空你本地的DNS缓存看看

@lemonda @ccdjh @aggron @lowstz 多谢大家的帮忙，我刚换了台电脑能访问了。

应该是我自己那台电脑的hosts文件有问题，以前加过google的hosts。

再次感谢！

提交表单后的跳转貌似有点问题:
点“说出来”后，chrome左下角显示”正在向geekiwi.appspot.com提交数据“，然后chrome地址栏就变成了geekiwi.appspot.com，于是显示被墙。再进入jiyin.it可以看到刚发布的内容

^_^ 要不要上个LUManager试试呀 http://www.v2ex.com/t/29571

@aggron 我也遇到这问题，但是不知道什么原因。。。

@guoquan 我用的是Cyberduck，还挺好用的。

@paloalto LUManager在vps管理上很全面，web服务器就是apache+nginx+tengine，1.1.9免费版就已经很强悍了，设置个反向代理什么的不在话下。
最近开始走商业化的2.0.x版更加面面俱到，都可以拿出来直接做idc了，个人使用更加游刃有余，欢迎了解哦。

不用那么多吧～～～
server
{
listen 80;
server_name www.aaa.com;

location / {
proxy_pass http://www.bbbb.com/;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

访问了一下，可以正常访问啊

@guoquan 麻烦您不要在技术讨论帖里面发这种广告了，好好的讨论串里面突然给你插一个这样的帖子
