/etc/sysctl.conf
net.ipv4.ip_local_port_range = 1024 65536
net.core.rmem_max=16777216
net.core.wmem_max=16777216
net.ipv4.tcp_rmem=4096 87380 16777216
net.ipv4.tcp_wmem=4096 65536 16777216
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_keepalive_time = 600
net.ipv4.tcp_tw_recycle = 1
net.core.netdev_max_backlog = 30000
net.ipv4.tcp_no_metrics_save=1
net.core.somaxconn = 262144
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_orphans = 8000
net.ipv4.tcp_max_syn_backlog = 8000
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
运行sysctl -p，使配置生效
