主要是修改内核参数进行限制：

在sysctl.conf文件中加入些参数：
' G) O5 k/ Y  I8 M
net.ipv4.ip_nonlocal_bind = 1
' g' y! k& ?$ b6 hnet.nf_conntrack_max=1048576
net.ipv4.tcp_keepalive_intvl = 3
net.ipv4.tcp_keepalive_time = 60
net.ipv4.tcp_keepalive_probes = 8
# F3 C6 M2 j2 h* `
1 h" G3 W: {. F. j$ |: @

执行下
0 C2 a( f# x4 fsysctl -p
/ u7 Z; N  W; {8 e9 ~$ D# i. l' E
. `4 Q+ W" b& k0 J6 i$ j' h7 z$ ~: j
重启haproxy服务即可
