13-51 nginx优化-内核参数调整

网络参数调优

[root@localhost 1.com]# sysctl -a |grep tw_buckets

sysctl: reading key "net.ipv6.conf.all.stable_secret"
sysctl: reading key "net.ipv6.conf.default.stable_secret"
sysctl: reading key "net.ipv6.conf.ens33.stable_secret"
sysctl: reading key "net.ipv6.conf.lo.stable_secret"
net.ipv4.tcp_max_tw_buckets = 4096
设置

[root@localhost 1.com]# vi  /etc/sysctl.conf

添加

net.ipv4.tcp_fin_timeout =6
net.ipv4.tcp_keepalive_time =30
net.ipv4.tcp_max_tw_buckets =8000
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_syncookies = 2
net.ipv4.tcp_max_syn_backlog = 30000
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_synack_retries = 2
net.ipv4.ip_local_port_range =1025 61000
net.ipv4.tcp_keepalive_intvl  = 3
net.ipv4.tcp_keepalive_probes  = 2

生效命令

[root@localhost ipv4]# sysctl -p

net.ipv4.tcp_fin_timeout = 6
net.ipv4.tcp_keepalive_time = 30
net.ipv4.tcp_max_tw_buckets = 8000
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_syncookies = 2
net.ipv4.tcp_max_syn_backlog = 30000
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_synack_retries = 2
net.ipv4.ip_local_port_range = 1025 61000
net.ipv4.tcp_keepalive_intvl = 3
net.ipv4.tcp_keepalive_probes = 2
