提升服務器的文件句柄打開打開
vi /etc/security/limits.conf
增加
* soft nofile 65536
* hard nofile 65536
vi /etc/sysctl.conf
在末尾增加以下內容：
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768

內核生效命令
sysctl -p
| error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key error: "net.bridge.bridge-nf-call-iptables" is an unknown key error: "net.bridge.bridge-nf-call-arptables" is an unknown key |
當我們執行sysctl -p時，報錯說key未知。這是因爲我們沒有加載bridge模塊，需要手工加載。解決過程如下：
lsmod|grep bridge
modprobe bridge
lsmod|grep bridge
運行以上命令再生效內核就不會報錯了
