Re开启负载均衡SLB后ECS存在大量TIMEWAIT的内网80端口连接 我也遇到这个问题了，不知道如何解决 开启负载均衡SLB后ECS会存在大量TIMEWAIT的内网80端口连接(几秒内升到2W预设值)，不知道如何解决，不走SLB通过另一个ECS压力测试时，仅会出现极少量(低于500)的TIMEWAIT ECS的sysctl.conf配置如下： net.ipv4.ip_forward = 0 net.ipv4.conf.all.rp_filter = 0 net.ipv4.conf.default.rp_filter = 0 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.ipv4.neigh.default.gc_stale_time = 120 net.ipv4.conf.default.arp_announce = 2 net.ipv4.conf.all.arp_announce = 2 net.ipv4.conf.lo.arp_announce = 2 net.ipv4.tcp_fin_timeout = 30 net.ipv4.tcp_keepalive_time = 300 net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_timestamps = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_tw_recycle = 1 net.ipv4.ip_local_port_range = 1024 65000 net.ipv4.tcp_max_tw_buckets = 20000 net.core.somaxconn = 81920 net.core.netdev_max_backlog = 81920 net.ipv4.tcp_max_syn_backlog = 81920 net.ipv4.tcp_synack_retries = 3 net.ipv4.tcp_max_orphans = 3276800 net.ipv4.tcp_no_metrics_save = 1 net.ipv4.tcp_sack = 1 net.ipv4.tcp_window_scaling = 1 压力测试命令为： ab -k -c10000 -n400000 url ------------------------- Re开启负载均衡SLB后ECS存在大量TIMEWAIT的内网80端口连接 目前SLB服务器的机器访问ECS全部采用的是http 1.0短链接协议，而真实用户访问SLB时采用的是http 1.1，经过SLB服务器中转之后变为了http 1.0，我猜这是导致大量TIME_WAIT的一个主要原因！
