已经试过 vi /etc/sysctl.conf # Decrease the time default value for tcp_fin_timeout connection net.ipv4.tcp_fin_timeout = 30 # Decrease the time default value for tcp_keepalive_time connection net.ipv4.tcp_keepalive_time = 1800 # 探测次数 net.ipv4.tcp_keepalive_probes=2 # 探测监控秒数 net.ipv4.tcp_keepalive_intvl=2 保存退出后执行:sysctl -p 没用。。。
