nginx反向代理优化配置

主模块配置:

　　http模块

user nginx;
worker_processes 1;#配置进程数

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

worker_rlimit_nofile 204800;

events {
use epoll;
worker_connections 20480;#允许客户端最大连接数
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
server_tokens off; #隐藏版本号

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

log_format access_log_json '{"user_ip":"$http_x_real_ip","lan_ip":"$remote_addr","log_time":"$time_iso8601","user_req":"$request","http_code":"$status","body_bytes_sent":"$body_bytes_sent","req_time":"$request_time","user_ua":"$http_user_agent"}';#日志以json格式输出
access_log /var/log/nginx/access.log access_log_json;

sendfile on;
tcp_nopush on;

keepalive_timeout 65;
autoindex off;
client_header_timeout 15s;
client_body_timeout 60s;
send_timeout 60s;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 2;

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

虚拟主机配置

server
    {
    listen   80;
    server_name  localhost;



    location / {
        proxy_pass http://172.17.0.9:3000;
                proxy_cache_valid    200 301 302 30m;
                expires 10d;
        include proxy.conf;
        }
    location /socket.io/ {
        proxy_pass http://172.17.0.9:8081/socket.io/;
        include proxy.conf;
        }
    location ~* ^/(video|game|music) {
        root /usr/share/nginx/html;
        include proxy.conf;

                expires 10d;
        }

}
