resin 出现大量CLOSE_WAIT 状态

优化linux 内核参数。

修改命令：vi /etc/sysctl

net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_fin_timeout = 3
net.ipv4.tcp_keepalive_time = 30
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 1024    65000
net.ipv4.tcp_max_syn_backlog = 8192

net.ipv4.tcp_max_tw_buckets = 5000

生效参数：/sbin/sysctl -p
