nginx性能优化调整

发表于 | 
worker_processes auto; #默认是1，通常设置为CPU 个数，如不清楚，可设为auto.
worker_connections 10240; #默认值是1024，单个worker进程处理最大连接数.
keepalive_requests 128; #单个持久连接最大发送请求数，默认100
keepalive_timeout 60; #空闲持久连接超时时间
keepalive 32; #upstream持久连接
proxy_http_version 1.1;
proxy_set_header Connection "";
sendfile on;

缓存：

location ~* \.(jpg|jpeg|png|gif|ico|js|htm|html)$ { 
     expires 10d;
}

开启压缩

gzip  on;
gzip_min_length 1k;
gzip_buffers   4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types    text/plain application/x-javascript text/css application/xml;
gzip_vary on;

关闭access日志打印

http {
    access_log off;
}

nofile and nproc 设置为合理的值, 修改/etc/security/limits.conf

myuser    -    nofile    10240
myuser    -    nproc    10240

修改kernel参数

net.ipv4.ip_local_port_range = 32768    60999
net.ipv4.tcp_fin_timeout = 60
net.ipv4.tcp_tw_reuse = 1 #TCP连接重用
net.core.somaxconn = 256 #该项设置等待被Nginx接受的连接的排队大小
