nginx静态处理 优化Linux内核参数

vi /etc/sysctl.conf
02 # Add
03 net.ipv4.tcp_max_syn_backlog = 65536
04 net.core.netdev_max_backlog =  32768
05 net.core.somaxconn = 32768
06
07 net.core.wmem_default = 8388608
08 net.core.rmem_default = 8388608
09 net.core.rmem_max = 16777216
10 net.core.wmem_max = 16777216
11
12 net.ipv4.tcp_timestamps = 1
13 net.ipv4.tcp_synack_retries = 2
14 net.ipv4.tcp_syn_retries = 2
15
16 net.ipv4.tcp_tw_recycle = 1
17 #net.ipv4.tcp_tw_len = 1
18 net.ipv4.tcp_tw_reuse = 1
19
20 net.ipv4.tcp_mem = 94500000 915000000 927000000
21 net.ipv4.tcp_max_orphans = 3276800
22
23 #net.ipv4.tcp_fin_timeout = 30
24 #net.ipv4.tcp_keepalive_time = 120
25 net.ipv4.ip_local_port_range = 1024  65535
26 net.ipv4.ip_conntrack_max = 655360
27 net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 180
28 使配置立即生效：
29 /sbin/sysctl -p
30 如果出现error: "net.ipv4.ip_conntrack_max" is an unknown key
31 error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_established" is an unknown key
32 解决：
33
34 modprobe ip_conntrack
35
36 echo "modprobe ip_conntrack" >> /etc/rc.local
37
38 modprobe(module probe)
39
40 功能说明：自动处理可载入模块。
