Nginx常用配置

代理设置ip限制

location / {
    #放开某个主机
    allow 127.0.0.2;
    allow 127.0.0.3;
    #限制所有主机
    deny  all;
    proxy_http_version 1.1;
    proxy_set_header Connection "keep-alive";
    proxy_set_header X-Real-IP $remote_addr;
    if (!-f $request_filename) {
        proxy_pass http://127.0.0.1:9999;
    }
}

负载均衡

upstream xxxxxxx {
    # weight权重
    server  127.0.0.1:9911 weight=1;
    server  127.0.0.1:9912 weight=2;
    server  127.0.0.1:9913 weight=7;
}
server
{
    listen 80;
    server_name test.xxx.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/xxx/xxx;
    location / {
        proxy_pass         http://xxxxxxx;
        proxy_set_header   Host             $host;
        proxy_http_version 1.1;
        proxy_set_header Connection "keep-alive";
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

代理到php-fpm

server
{
    listen 80;
    server_name test.xxx.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/xxx/xxx;
    location / {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

代理指定路由

# /xx/xx url的后缀
location = /xx/xx {
  proxy_http_version 1.1;
  proxy_set_header Connection "keep-alive";
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_pass http://api.xxx.com/xx/xx/xx;
  break;
}

重写路由

# 重写到其他服务会导致post请求方式变get 可以使用如上代理方式
location / {
    rewrite ^/xxx?(.*) /index.php?c=speech&m=index&$1 last;
    rewrite ^/xxx http://xxx.com/xxx/xx/index last;   
}

代理静态文件

location ^~/dist/{
	alias /www/xxx/static/;
}

location ^~/xxx/dist/{
    alias /www/xxx/static/;
}

代理指定服务API、websocket

location /api/ {
    # 将客户端的 Host 和 IP 信息一并转发到对应节点
    proxy_http_version 1.1;
    proxy_set_header Connection "keep-alive";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    if (!-f $request_filename) {
         proxy_pass http://127.0.0.1:8801;
    }
}

location /ws/ {
    proxy_redirect off;
    proxy_pass http://127.0.0.1:8802/;
    proxy_set_header Host $host;
    proxy_set_header X-Real_IP $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr:$remote_port;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;   # 升级协议头
    proxy_set_header Connection upgrade;
}

不同前缀 代理到同一个服务

location ~ (/api|/admin) {
    # 将客户端的 Host 和 IP 信息一并转发到对应节点
    proxy_http_version 1.1;
    proxy_set_header Connection "keep-alive";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    if (!-f $request_filename) {
         proxy_pass http://127.0.0.1:8801;
    }
}

处理跨域

location ~ (/api|/admin) {
   if ($request_method = 'OPTIONS') {
       add_header Access-Control-Allow-Origin *;
       add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS, DELETE';
       add_header Access-Control-Allow-Headers 'DNT,Keep-Alive,User-Agent,Cache-Control,Content-Type,Authorization,X-Token';
       return 204;
    }
    # 将客户端的 Host 和 IP 信息一并转发到对应节点
    proxy_http_version 1.1;
    proxy_set_header Connection "keep-alive";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    if (!-f $request_filename) {
         proxy_pass http://127.0.0.1:8801;
    }
}

设置https证书

server
{
    listen 80;
    listen 443 ssl http2;
    server_name xxx.putyy.com;
    .....
    ssl_certificate    /www/cert/fullchain.pem;
    ssl_certificate_key    /www/cert/privkey.pem;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;
    add_header Strict-Transport-Security "max-age=31536000";
    error_page 497  https://$host$request_uri;
    ......
}

替换内容

# 比如替换掉响应中指定url
 sub_filter 'https://s.xxx.cn/assets/' 'https://s-xxx-cdn.xxx.cn/assets/';
        sub_filter_once off;
