nginx静态处理 优化Linux内核参数

vi /etc/sysctl.conf

# 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。
