  昨日,有朋友问我,他将Web服务器换成Nginx 0.6.31  + PHP 4.4.7(FastCGI)后,有时候访问会出现“502 Bad Gateway”错误,如何解决。

  我让按照以下两个步骤去解决,最后在第2步中将FastCGI的timeout时间增加为300,问题解决:

  PS:比较羡慕迅雷的Web服务器,16G内存。



  1、查看当前的PHP FastCGI进程数是否够用:
netstat -anpo | grep "php-cgi" | wc -l

  如果实际使用的“FastCGI进程数”接近预设的“FastCGI进程数”,那么,说明“FastCGI进程数”不够用,需要增大。



  2、部分PHP程序的执行时间超过了Nginx的等待时间,可以适当增加nginx.conf配置文件中FastCGI的timeout时间,例如:
......
http
{
......
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
......
}
......

似乎php模块丢失,wget也会出现502错误,reload一下可以解决?

貌似按照楼主给出的步骤全做完就会出现502,之前只做了php-fpm和nginx反而可以。

成功架设Nginx+Php Web服务器之后的一个总结,成功设置Nginx开启多域名多站点,并且不会出现502 Bad Gateway错误!

接近预设的“FastCGI进程数”这个在那里查看。
如何知道预设的是多少

宴哥,我最近使用你的nginx+php文档,来跑我的php论坛,首页是在测试,环境是VM和rhel5.4
   但是自从第一次安装好后,后来重新编译就不行,很多时候都是php不能正常显示,测试页也不能打开,
502 bad gateway这个提示。。。

嘿嘿  我也发现这样的问题了  结果是nginx的日志文件太大   现在已经好了     每天定时替换日志文件,    不过还在想有其他的方式没。    不晓得我是特例还是日志文件大了也会导致502   如果张老师验证会导致还希望加上,
