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:
- net.ipv4.ip_forward=0
- net.ipv4.conf.default.rp_filter=1
- net.ipv4.conf.default.accept_source_route=0
- kernel.sysrq=0
- kernel.core_uses_pid=1
- net.ipv4.tcp_syncookies=1
- kernel.msgmnb=65536
- kernel.msgmax=65536
- kernel.shmmax=68719476736
- kernel.shmall=4294967296
- net.ipv4.tcp_max_tw_buckets=6000
- net.ipv4.tcp_sack=1
- net.ipv4.tcp_window_scaling=1
- net.ipv4.tcp_wmem=81924336600873200
- net.ipv4.tcp_rmem=327684336600873200
- net.core.wmem_default=8388608
- net.core.rmem_default=8388608
- net.core.rmem_max=16777216
- net.core.wmem_max=16777216
- net.core.netdev_max_backlog=262144
- net.core.somaxconn=262144
- net.ipv4.tcp_max_orphans=3276800
- net.ipv4.tcp_max_syn_backlog=262144
- net.ipv4.tcp_timestamps=1
- net.ipv4.tcp_synack_retries=1
- net.ipv4.tcp_syn_retries=1
- net.ipv4.tcp_tw_recycle=1
- net.ipv4.tcp_tw_reuse=1
- net.ipv4.tcp_mem=78643210485761572864
- net.ipv4.tcp_fin_timeout=30//phpfensi.com
- #net.ipv4.tcp_keepalive_time=30
- net.ipv4.tcp_keepalive_time=300
- net.ipv4.ip_local_port_range=102465000
使用sysctl -p使其生效,有需要的同学可以去试试.
