nginx安装及优化

6、优化Linux内核参数

# vi /etc/sysctl.conf 
在末尾增加以下内容： 
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000    65000
使配置立即生效：# /sbin/sysctl -p。

防止过多的socket处于time_wait状态
