最近在爬的数据直接丢进nginx后台拿，拉的速度慢。。。
于是开始简单优化一下。
nginx version: nginx/1.13.6
- 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
- 修改 /etc/security/limits.conf 文件
soft nofile 4096 hard nofile 4096 - 修改 /etc/nginx/nginx.conf 文件
