最近在爬的數(shù)據(jù)直接丟進(jìn)nginx后臺(tái)拿，拉的速度慢。。。
于是開始簡(jiǎn)單優(yōu)化一下。
nginx version: nginx/1.13.6

1. 修改 /etc/sysctl.conf文件

net.core.somaxconn = 65536
net.ipv4.tcp_max_tw_buckets = 1440000
net.ipv4.ip_local_port_range = 1024 65000
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_max_syn_backlog = 3240000

2. 修改 /etc/security/limits.conf 文件
   soft nofile 4096 hard nofile 4096
3. 修改 /etc/nginx/nginx.conf 文件
