Web服務器Nginx常見的配置選項整理

　　Google上有豐富的 Nginx 的教程和樣本配置文件，但很多時候時候，配置這些是一些技巧，一直對大家很有幫助。

Include 文件

　　不要在您的主 nginx.conf 文件中配置所有的東西，你需要分成幾個較小的文件。您的同事會很感激你的。比如我的結構，我定義我的 upstream 的 pool 的為一個文件，和一個文件定義 location 處理服務器上其它的應用。

例子：

upstreams.conf

upstream cluster1 {
fair;
server app01:7060;
server app01:7061;
server app02:7060;
server app02:7061;
}

upstream cluster2 {
fair;
server app01:7071;
server app01:7072;
server app02:7071;
server app02:7072;
}

locations.conf

location / {
root /var/www;
include cache-control.conf;
index index.html index.htm;
}

location /services/service1 {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

add_header Pragma "no-cache";

proxy_pass http://cluster1/;
}

location /services/service2 {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

add_header Pragma "no-cache";

proxy_pass http://cluster2/service2;
}

servers.conf

server {
listen 80;
include locations.conf;
}

　　現在，你的 nginx.conf 看起來非常的干淨和簡單（仍然可以分開更多，來更包括文件，比如分離gzip的配置選項）

nginx.conf

worker_processes 4;
worker_rlimit_nofile 10240;

events {
worker_connections 10240;
use epoll;
}

http {
include upstreams.conf;

include mime.types;
default_type application/octet-stream;

log_format custom '$remote_addr - $remote_user [$time_local] '
'"$request" $status $bytes_sent '
'"$http_referer" "$http_user_agent" "$http_x_forwarded_for" $request_time';

access_log /usr/local/nginx/logs/access.log custom;

proxy_buffering off;
sendfile on;
tcp_nopush on;
tcp_nodelay on;

gzip on;
gzip_min_length 10240;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml application/xml+rss image/svg+xml application/x-font-ttf application/vnd.ms-fontobject;
gzip_disable "MSIE [1-6].";

# proxy cache config
proxy_cache_path /mnt/nginx_cache levels=1:2
keys_zone=one:10m
inactive=7d max_size=10g;
proxy_temp_path /var/tmp/nginx_temp;

proxy_next_upstream error;

include servers.conf;
}

　　這 nginx.conf 文件是使用了一些不太常見的配置選項，它值得指出其中一些重要的。
