系统是Ubuntu server 11.10的
总是出现502错误,纠结了很长时间,发现把PHP编译的代码修改下居然好了,就是去掉php编译的 一个选项 --with-openssl ,不知道是什么原因,麻烦管理员看下日志。

说明php-cgi没有运行。。。请求量一旦在一个时间很多,php-cgi难道就挂了。。。

留个记号。我也遇到了。
不过重启一下就OK了。
我发现这个和硬盘和内存有关系。
我的自动备份设置为凌晨3点。
每次都是在凌晨3点多就出现了这个问题。
或许是我的硬盘满了。自动备份时无法完成压缩出现了这个问题。
又或者是我的内存太小。
我试了一下。
我在凌晨3点当VPS执行自动压缩备份时。
打开网站的速度非常慢。
我的网站数据2G。一键lnmp。linode512

我必须顶一下这个帖子。

以前是  lnmp的升级为 lnmpa的兄弟  和上面所有的问题都没有关系, 使用/root/vhost.sh 将所有的虚拟主机重新添加一遍即可。我折腾了6个小时!!!
