军哥请进，关于1.3版本在4核8G服务器上的nginx和PHP的性能优化建议

淡如水

如题，相关的性能优化，该怎么做合适？

默认都是自动优化了的

好的，谢谢，阿军哥！

阿军哥，漏问一问题。对于别人恶意用压测工具如loadruner,Jmeter之类的工具来刷网站，能通过配置文件过滤掉吗？

licess

如果是特定的useragent，可以屏蔽useragent

useragent可以日志里查看

nginx对应虚拟主机上设置

        if ($http_user_agent ~* abcde|fghijk|lmno) {
            return 444;
        }

军哥，咱们的脚本在腾讯云上不能运行吗？
安装log会报 Couldn't resolve host 'mirrors.tencentyun.com' ，找不到这个地址，相应的脚本改怎么改，让它不连这个地址？

我用的是lnmp1.3-full完整的安装包，安装上需要的东西应该已经齐全，不需要下载才是，腾讯云不知道搞什么飞机。

主要原因是腾讯云的dns问题，安装帖子中的方法目前能正常安装

腾讯云都是用内部dns才能用他们内网的源，不要就换成他们内部的dns，要不就换其他源
