阿里云服务器 LNMPA CPU100%求救

shjowhut

阿里云服务器用的是LNMPA，每天都报CPU100%，有半年了，实在是没办法，列出几条错误日志，请军哥帮忙 。感激不尽，每天重启，实在是太痛苦了
一、IP-error_log 里全是这种错误，每秒20条左右，换着IP来，这是有人在攻击我吗,有什么办法可以禁掉？也有不少IP是10.159.63.35这样的局域网IP。

二、error_log 里面，APACHE每次启动会提示以下，这个有没有影响，有什么办法解决吗？我在httpd.conf里也没找到与SSL相关的内容。
[Tue Mar 11 15:25:57 2014] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
[Tue Mar 11 15:25:57 2014] [notice] suEXEC mechanism enabled (wrapper: /usr/local/apache/bin/suexec)

error_log 里面还会不停地出现sh: -t: command not found，没有显示时间，一出现就是几千条，请问有办法找出原因吗？

前面的日志都是些类似访问日志的，文件不存在的 这些没什么用处
要排查的话比较麻烦，简单的话ps aux 看哪个进程占用cpu多，再看情况慢慢分析
