在性能测试的是遇到以上报错的意思是,连接超时、地址已占用

原因:发起方,端口数量不足,导致请求失败

方法:

win10:

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

新建2个,DWORD 32值,值为十进制

MaxUserProt:65535,10进制

TcpTimedWaitDelay:30,10进制

重启

linux:

sysctl -w net.ipv4.ip_local_port_range="1024 65535" #大约有6.4w个端口

sysctl -w net.ipv4.tcp_tw_reuse = 1 # 表示开启重用,允许将TIME-WAITsockets重

sysctl -w net.ipv4.tcp_tw_recycle = 1 # 表示开启TCP连接中TIME-WAITsockets的快速

sysctl -w net.ipv4.tcp_fin_timeout = 5 # 修改系统默认的TIMEOUT时间为5秒;调小

sysctl -w net.ipv4.tcp_max_syn_backlog = 8192 # 进入syn包的最大请求队列;调大

sysctl -w net.ipv4.tcp_max_tw_buckets = 5000 # 表示系统同时保持TIME_WAIT套接字

sysctl -p # 配置生效
