php没有编译安装成功。

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。

这个是修改后的日志文件，麻烦管理员看下是哪里出问题了
谢谢了

max_requests 多少值合适了？ 我这服务器。。一旦访问的人多了。。。就502

licess

可以5个5个的往上加着试试

terryc007

max_request 我设置为30124 max_children = 500

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！！！

错误信息如下：

Starting php_fpm /etc/init.d/php-fpm: line 61: /usr/local/php/bin/php-cgi: No such file or directoryfailed

可能php是没有编译安装成功
