nginx优化总结,nginx通用优化配置文件
[root@nginx ~]# cat nginx.conf
user www; # nginx进程启动用户
worker_processes auto; #与cpu核心一致即可
worker_cpu_affinity auto; # cpu亲和
error_log /var/log/nginx/error.log warn; # 错误日志
pid /run/nginx.pid;
worker_rlimit_nofile 35535; #每个work能打开的文件描述符,调整至1w以上,负荷较高建议2-3w
events {
use epoll; # 使用epoll高效网络模型
worker_connections 10240; # 限制每个进程能处理多少个连接,10240x[cpu核心]
}
http {
include mime.types;
default_type application/octet-stream;
charset utf-8; # 统一使用utf-8字符集
# 定义日志格式
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
#定义json日志格式
log_format json_access '{"@timestamp":"$time_iso8601",'

access_log /var/log/nginx/access.log main; # 访问日志
server_tokens off; # 禁止浏览器显示nginx版本号
client_max_body_size 200m; # 文件上传大小限制调整
# 文件高效传输,静态资源服务器建议打开
sendfile on;
tcp_nopush on;
# 文件实时传输,动态资源服务建议打开,需要打开keepalive

keepalive_timeout 65; #开启tcp长连接,以及长连接超时时间keepalived
# Gzip 压缩
gzip on;
gzip_disable "MSIE [1-6]\."; #针对IE浏览器不进行压缩

gzip_comp_level 2; #压缩级别
gzip_buffers 16 8k; #压缩的缓冲区
