event,linux优化,Register内外端口也都是通的

执行 php start.php status 看下172.31.18.200 这台服务器是不是没装event扩展，没装的话装下。
如果不是扩展的原因可能是因为linux内核没有按照手册 https://www.workerman.net/doc/workerman/appendices/kernel-optimization.html 优化
如果还有问题尝试关闭下 172.31.18.200 的iptables(有开启的话)，有时iptables跟踪表满了也会导致超时。
还有一种情况是172.31.18.200这台服务器负载高，导致什么都慢。
