不知道 什么问题

licess

按这个日志有经常运行时间很长的程序，可以开慢日志看看是哪个程序文件

jinjin

军哥我遇到的问题跟他一样，总是502  最后我把php-fpm的设置为static，然后重新设置了
pm = static
pm.max_requests = 500
pm.max_children = 100
pm.start_servers = 90
pm.min_spare_servers = 30
pm.max_spare_servers = 150
rlimit_files = 65535

502倒是不会出现了，但是php-fpm占用的cup很大，请问是怎么回事：机器是8核8G10M带宽，


网站访问量如下
        浏览次数(PV)         独立访客(UV)         IP         新独立访客         访问次数
今日         9003         2608         2733         633         5138
昨日         40069         7728         8765         3986         23226

licess

用static肯定占用资源要多

看日志都是到/home/wwwroot/www.xxxxx.com/ThinkPHP/Common/runtime.php:237
[0x00007fbe0c6e28a8] +++ dump failed
这个地方可能与这个相关的有关

jinjin

恩恩谢谢军哥，我还想问一下服务器现在是4核32G100M带宽，在韩国那边，目标用户群主要在国内（额，服务器在韩国其中原因我也不想说了）。核心业务逻辑就是一些数据计算的东西，每天的pv大概在4万。有些客户反应说有时候快的像飞一样，有时候慢的像蜗牛一样，如果排除用户那边网络的原因还有什么其他可能吗？

我从top里看到php-fpm占用的cpu时不时的就飙到100%   我安装了phptrace 查看占用内存多进程号得到下面的结果。

有一个朋友建议说是让安装一个xcache，因为现在用的人挺多的，我还没有敢试，请问有什么大的提升作用吗？或者针对我这样时快时慢的问题您有没有什么解决的方法？

licess

cpu几个核心都100%的话即使带宽充足也会影响访问

xcache会进行缓存，应该能起到一些作用

jinjin

恩恩好的哥  我夜里给他装上xcache试试，这个安装xcache了之后使用php -v就会报502您那边有什么解决方法吗？附件里是我的cpu使用情况，有时候正常有时候就很高，配置还是之前的那个
pm = static
pm.max_requests = 500
pm.max_children = 100
pm.start_servers = 90
pm.min_spare_servers = 30
pm.max_spare_servers = 150
rlimit_files = 65535
我看其他地方介绍的是如果内存足够大的话pm使用static的，您说我有必要换成静态的吗？

licess

php -v后502好像是xcache与php 5.4版本的兼容性问题
static要好些吧

jinjin

军哥你好，我安装了xcache速度提升了一些，但是诊断的时候出现了
“PHP 编译时错误         警告         至少在编译一个或多个您的 PHP 代码时发生编译错误         编译失败的 PHP 代码是无法缓存的. 这通常意味着您的 PHP 代码有语法错误. 请启用 error_log 调查具体错误原因并修复您的代码. 重启 PHP 前这个警告不会消失”

我在php.ini里配置了
log_errors = On
error_log = "/usr/local/php/var/log/php-error.log"  配置之后php-error.log 里啥也没有记进去     service php-fpm reload重新载入了的，请问这个怎么回事

licess

按他这里面的提示可能是php代码语法错误

jinjin

恩恩对  是语法错误  编译的有问题  但是我开启了php的错误日志怎么什么也没有记录进去呢？之前代码也不是我写的 所以还是比较困惑 不知道从哪里找问题

licess

这个错误日志需要在php-fpm.conf里设置，加上catch_workers_output = yes，错误信息就会记录到php-fpm里error_log设置的文件里

或php-fpm.conf里加上
php_admin_value[error_log] = /usr/local/php/var/log/php-error.log
php_admin_flag[log_errors] = on

上述两种方法都行，重启php-fpm生效

jinjin

恩恩好的  我试试  谢谢军哥

jinjin

军哥我们的问题还是没有解决，网站有时候打开很快，有时候打开很慢，我们能不能找您有偿的解决一下，今天客户那边刚开完会，明天说是访问量会更大，您看看能行吗？我的qq是983735268
