Nginx：性能优化

1.limit配置

如果想了解更多请查看linux limit

在/etc/security/limits.conf末尾添加如下内容

*               soft    nofile            65535
*               hard    nofile            65535
*               soft    nproc             65535
*               soft    nproc             65535

2.最大文件打开数&IO模型&单进程最大连接数

修改/etc/nginx/nginx.conf文件


user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

# 工作进程最大打开文件数
worker_rlimit_nofile 65535;

events {
    # 使用epoll模型
    use epoll;
    # 单个进程最大连接数
    worker_connections  20480;
}

...

3.CPU亲和

将Nginx工作进程与逻辑CPU绑定，减少Nginx工作进程在逻辑CPU中切换的性能损耗。

3.1.查看逻辑CPU数量

htop

htop

3.2.绑定逻辑CPU

修改/etc/nginx/nginx.conf文件


user  nginx;
# 工作进程数量
worker_processes  2;
# 绑定工作进程与逻辑CPU
worker_cpu_affinity 01 10;

...

4.gzip

修改/etc/nginx/nginx.conf文件

...

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    # gzip配置
    gzip  on;
    # IE6及以下浏览器不使用gzip
    gzip_disable "MSIE [1-6]\.";
    gzip_min_length  1k;
    gzip_buffers     4 16k;
    gzip_http_version 1.1;
    gzip_types       text/plain application/json text/javascript application/x-javascript text/css application/xml;
    gzip_vary on;

    include /etc/nginx/conf.d/*.conf;
}
