优化得很好的sysctl.conf配置
时间:2014-12-12 00:24来源:linux.it.net.cn 作者:IT
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 |
|
05 |
kernel.core_uses_pid = 1 |
|
06 |
net.ipv4.tcp_syncookies = 1 |
|
09 |
kernel.shmmax = 68719476736 |
|
10 |
kernel.shmall = 4294967296 |
|
11 |
net.ipv4.tcp_max_tw_buckets = 6000 |
|
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 |
|
23 |
net.ipv4.tcp_max_syn_backlog = 262144 |
|
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.
