lnmp1.5包安装的 lnmpa环境架构 出现CPU 占用过高的情况 求帮助
本帖最后由 Sandy 于 2019-5-24 10:58 编辑使用的是lnmp1.5安装包，安装的环境是lnmpa php5.6 MariaDB10.2 Jemalloc apache2.4.33
服务器 12核 8G 10M
同时网络并发最高20
服务器启动72小时后
top指令查看 12核CPU 基本全部核心都是 100% 占用
有多个httpd进程
服务器明显出现卡顿问题
重起apache CPU恢复 一段时间 （超72小时） 后 CPU 又被全部占满
服务器有多个WEB 站点 部分开启了https
有高手指点下 怎么优化吗？？？
这个不好确定原因
建议strace追踪占cpu较高的pid看看 top - 16:16:52 up 2 days, 23:05,2 users,load average: 45.34, 45.31, 44.88

https.conf 启用了LoadModule mpm_event_module modules/mod_mpm_event.so
发现配置里面好像 缺少 mpm_event_module的配置信息找了资料添加配置信息如下 不知道能不能解决这个问题
<IfModule mpm_event_module>
StartServers 3

</IfModule>
果然没有用，就没有愿意指点下的大神吗？哎。。。。
