CLOSEWAIT隔那么三到五小时就往上飙很高

我之前也是参考这个解决了TIME_WAIT的问题。但是这里没有CLOSE_WAIT的问题

-------------------------

这个也搞过了的。还是有。给你看看我的sysctl.conf


vm.swappiness = 0
net.ipv4.neigh.default.gc_stale_time=120
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.default.arp_announce = 2
net.ipv4.conf.all.arp_announce=2
net.ipv4.tcp_max_tw_buckets = 5000
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 1024
net.ipv4.tcp_synack_retries = 2
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv4.conf.lo.arp_announce=2
net.ipv4.icmp_echo_ignore_all = 1
net.ipv4.ip_local_port_range = 1024 65000

net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 1200
net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_max_tw_buckets = 1000
net.ipv4.tcp_keepalive_probes = 3
net.ipv4.tcp_keepalive_intvl = 15

net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait = 6
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 180
