军哥，麻烦看看这个问题咋解决。
网站打开正常，ocp.php看了也正常，有击中，这个问题跟opcache有关的。看了 php-fpm.log 日志。而且是刚刚重启好 php-fpm ，日志提示准备握手马上就会出下面的这些警告。NOTICE: using inherited socket fd=8, "/tmp/php-cgi.sock"

全是这样的，不断的在刷新。然后我如果在 php.ini 里面将 opcache 关闭，重启php后，就不会有上面的这些错误了。确定是因opcache引发的问题。
首先我查了slow.log，无内容。
然后我将 php-fpm 工作进程设置成一个。
执行
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
ps -aux | grep php-fpm
获得进程数时，
strace -p 4250 当时因为php-fpm工作进程在开启，进程数都不断的在刷新。获得下面数据，麻烦军哥看看到底哪里出问题了。

[ 本帖最后由 ldlbf 于 2014-6-1 23:31 编辑 ] 军哥，SORRY，我错了，我开了N个窗口，其中有一个探针的窗口忘记关了，开太多了，看不到了，也不记得了。探针一直在刷新，所以一直都出现上述错误，晕死了。现在回过头来看 strace 才明白过来。:lol 晕死，现在 vi 用多了，在论坛进到页面里来想退到外面去，都不用鼠标了，习惯性的：q :L slowlog是设置的php-fpm.log里面的那个after后的时间吗 原帖由 licess 于 2014-6-2 10:25 发表 https://bbs.vpser.net/images/common/back.gif
slowlog是设置的php-fpm.log里面的那个after后的时间吗
嗯。我的slow.log设置的是1s，不是默认的10s，也没有记录。
因为设置10s，slow.log 里面无记录，所以设置成1s想看看slow.log里面有没有东西，也都是啥都没有。
[ 本帖最后由 ldlbf 于 2014-6-2 15:28 编辑 ] php-fpm.log里面有而slow.log里面没有可以看一下slow.log的权限 原帖由 licess 于 2014-6-2 21:08 发表 https://bbs.vpser.net/images/common/back.gif
php-fpm.log里面有而slow.log里面没有可以看一下slow.log的权限
有的呀。和 php-fpm.log 一样的呢。
-rw------- 1 root root115 Jun2 00:41 php-fpm.log
-rw------- 1 root root 0 Jun2 00:16 slow.log
难不成要改成 666 ？我之前也是担心没权限，还将 slow.log 和 php-fpm.log 都删除了。然后重启 php 后，两个文件都是可以自动创建，但仅仅php-fpm.log会马上记录，slow.php 里无记录。按道理来说，只要开启了 slow ，php-fpm.log 有记录的话，slow.log 应该有东西才是。而且我已经设的1s了。
开虚拟主机下面的网站就正常，php-fpm.log 里无记录，开探针就报这些错误，php-fpm.log里有记录，slow.log 里无记录。关了 opcache ，重启 php 开探针 php-fpm.log 里无记录，slow.log 里无记录。
[ 本帖最后由 ldlbf 于 2014-6-2 23:03 编辑 ] 哪应该就与opcache有关，就先别用这个了
