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 = 8192 4336600 873200
net.ipv4.tcp_rmem = 32768 4336600 873200
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 = 786432 1048576 1572864
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 = 1024 65000。
