最近找了个不错的sysctl.conf的优化参数,在网站响应上已经算不错了的,time超时连接据说几乎为0了.
系统:centos 5.x
sysctl.conf配置参数:
01
net.ipv4.ip_forward = 0
02
net.ipv4.conf.default.rp_filter = 1
03
net.ipv4.conf.default.accept_source_route = 0

09
kernel.shmmax = 68719476736
10

11
net.ipv4.tcp_max_tw_buckets = 6000
12
net.ipv4.tcp_sack = 1
13
net.ipv4.tcp_window_scaling = 1
14
net.ipv4.tcp_wmem = 8192 4336600 873200
15
net.ipv4.tcp_rmem = 32768 4336600 873200
16
net.core.wmem_default = 8388608
17
net.core.rmem_default = 8388608
18
net.core.rmem_max = 16777216
19
net.core.wmem_max = 16777216
20
net.core.netdev_max_backlog = 262144
21
net.core.somaxconn = 262144
22
net.ipv4.tcp_max_orphans = 3276800

24
net.ipv4.tcp_timestamps = 1
25
net.ipv4.tcp_synack_retries = 1
26
net.ipv4.tcp_syn_retries = 1
27
net.ipv4.tcp_tw_recycle = 1
28
net.ipv4.tcp_tw_reuse = 1
29
net.ipv4.tcp_mem = 786432 1048576 1572864
30
net.ipv4.tcp_fin_timeout = 30
31
#net.ipv4.tcp_keepalive_time = 30
32
net.ipv4.tcp_keepalive_time = 300
33
net.ipv4.ip_local_port_range = 1024 65000
使用sysctl -p使其生效,有需要的同学可以去试试.
