#Linux内核参数优化
sysctl -w net.ipv4.tcp_syncookies=1 #表示开启SYN
Cookies。当出现SYN等待队列溢出时，启用cookies来处理，可防范少量SYN攻击，默认为0，表示关闭
sysctl -w net.ipv4.tcp_tw_reuse=1 #表示开启重用。允许将TIME-WAIT
sockets重新用于新的TCP连接，默认为0，表示关闭
sysctl -w net.ipv4.tcp_tw_recycle=1 # 表示开启TCP连接中TIME-WAIT sockets的快速回收，默认为0，表示关闭
sysctl -w net.ipv4.tcp_fin_timeout=30 #表示如果套接字由本端要求关闭，这个参数决定了它保持在FIN-WAIT-2状态的时间
sysctl -w net.ipv4.tcp_max_tw_buckets=6000 #系统同时保持TIME_WAIT套接字的最大数量
sysctl -w net.core.somaxconn=262144
#表示系统同时保持TIME_WAIT套接字的最大数量，如果超过这个数字，TIME_WAIT套接字将立刻被清除并打印警告信息。默认为180000，改为5000。对于Apache、Nginx等服务器，上几行的参数可以很好地减少TIME_WAIT套接字数量，但是对于Squid，效果却不大。此项参数可以控制TIME_WAIT套接字的最大数量，避免Squid服务器被大量的TIME_WAIT套接字拖死。
sysctl -w net.ipv4.tcp_keepalive_time = 1200
#表示当keepalive起用的时候，TCP发送keepalive消息的频度。缺省是2小时，改为20分钟。
sysctl -w net.ipv4.ip_local_port_range = 1024 65000
#表示用于向外连接的端口范围。缺省情况下很小：32768到61000，改为1024到65000。
sysctl -w net.ipv4.tcp_max_syn_backlog = 8192
#表示SYN队列的长度，默认为1024，加大队列长度为8192，可以容纳更多等待连接的网络连接数。
