502错误，并且swap内存一直占满状态

604542720

军哥，求助，网站是小站，基本没人访问，但是今天报502错误，并且swap内存一直占满状态，我重启了下php-fpm，好了点，但是马上内存又开始占满了。。。。

我看置顶教程里面有这么介绍的  "可能因为phpcgi进程不够用而造成502，需要修改/usr/local/php/etc/php-fpm.conf 将其中的max_children值适当增加",  我设置大一些以后好像是正常了。

但是我的网站目前只有我一个人在测试使用，怎么会出现进程不够。。。

licess

swap都用完那就内存不够用了

不是说你一个人访问他内存就不占用了，你vps什么配置？

1G 物理内存，2G swap，跑了个wordpress
pm = dynamic
pm.max_children = 20
pm.start_servers = 6
pm.min_spare_servers = 3
pm.max_spare_servers = 20
我修改成这种配置了

licess

按这个设置的话应该不会，top看一下

而且我感觉改了php-fpm 的这些参数后，网站变的很慢了，经常需要重启php-fpm才能瞬间打开网站，但是过了一会后，又变慢了。。。php-fpm日志是这样的

这个是慢日志，已经到了刷新探针页面都卡的地步了。。。。。网站目前是测试阶段，基本上就我一个人访问。。。

解决了，是被人攻击了xmlrpc文件，重命名这个文件就可以了，一般来说这个文件作用不大
