Solve a large number of TIME_WAIT problems in Linux

In Linux, a large amount of TIME_WAIT-Linux Enterprise Application-Linux server application information is solved. The following is a detailed description. [Root @ web02 ~] # Vi/etc/sysctl. conf
Add the following content:
Net. ipv4.tcp _ tw_reuse = 1
Net. ipv4.tcp _ tw_recycle = 1
Net. ipv4.tcp _ syncookies = 1
Make kernel parameters take effect:
[Root @ web02 ~] # Sysctl-p
Readme:
Net. ipv4.tcp _ syncookies = 1 enable the TIME-WAIT socket reuse function, which is very effective for Web servers with a large number of connections.
Net. ipv4.tcp _ tw_recyle = 1
Net. ipv4.tcp _ tw_reuse = 1 reduce the time in the FIN-WAIT-2 connection state, so that the system can process more connections.
Net. ipv4.tcp _ fin_timeout = 30 reduces the time for TCP KeepAlive connection detection, enabling the system to process more connections.
Net. ipv4.tcp _ keepalive_time = 1800 increase the length of the tcp syn queue so that the system can process more concurrent connections.
Net. ipv4.tcp _ max_syn_backlog = 8192
