问题背景：
一台主机上面部署了N个SpringCloud应用，使用的注册中心是Nacos，长时间运行后会出现
java.lang.IllegalStateException: failed to req API:/nacos/v1/ns/instance after all servers([178.50.10.132:8848]) tried: failed to req API:http://178.50.10.132:8848/nacos/v1/ns/instance. code:500 msg: java.net.ConnectException: Cannot assign requested address (connect failed)
网上找了下原因，大致上是由于客户端频繁的连服务器，由于每次连接都在很短的时间内结束，导致很多的TIME_WAIT，以至于用光了可用的端 口号，所以新的连接没办法绑定端口，即“Cannot assign requested address”。是客户端的问题不是服务器端的问题。通过netstat，的确看到很多TIME_WAIT状态的连接。
client端频繁建立连接，而端口释放较慢，导致建立新连接时无可用端口。

解决办法
执行命令修改如下内核参数 （需要root权限）
调低端口释放后的等待时间，默认为60s，修改为15~30s：
sysctl -w net.ipv4.tcp_fin_timeout=30修改tcp/ip协议配置， 通过配置/proc/sys/net/ipv4/tcp_tw_resue, 默认为0，修改为1，释放TIME_WAIT端口给新连接使用：
sysctl -w net.ipv4.tcp_timestamps=1修改tcp/ip协议配置，快速回收socket资源，默认为0，修改为1：
sysctl -w net.ipv4.tcp_tw_recycle=1允许端口重用：
sysctl -w net.ipv4.tcp_tw_reuse = 1
