本文主要是Nginx做一个简单的反向服务器代理和静态文件缓存。
反向代理(Reverse Proxy)方式是指以代理服务器来接受internet上的连接请求,然后将请求转发给内部网络上的服务器,并将从服务器上得到的结果返回给internet上请求连接的客户端,此时代理服务器对外就表现为一个服务器
我们就开始动手吧。
1. Vistudio 创建两个简单的 WebApplication (Web Forms),一个叫WebApplication1,一个叫 WebApplication2. 为了区别两个应用程序,把default页面做一些修改,用来识别。
比如添加 Application One, Application Two等。
2. 发布两个工程,然后IIS添加两个站点,端口分别用 8050,8060.
3. 测试站点, 输入 http://localhost:8050,http://localhost:8060,均能正常访问
4. 下载安装 Nginx,参考上一篇文章,我这里监听的是 2016端口
5. 找到 c:\nginx-1.9.9\conf\nginx.conf 文件,修改如下
#user nobody; worker_processes 1; error_log logs/error.log; error_log logs/error.log notice; error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include 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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; upstream windowsapp.com{ server 127.0.0.1:8050 weight=1; server 127.0.0.1:8060 weight=1; } server { listen 2016; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; #location / { # root html; # index index.html index.htm; #} #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} location / { proxy_pass http://windowsapp.com; } location ~ \.(css)$ { root /nginx-1.9.9/staticfiles/; expires 7d; } location ~ \.(js)$ { root /nginx-1.9.9/staticfiles/; expires 7d; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
关注点:
1. http 下 server listen 配置为 2016,表示监听 2016端口
2. upstream集群 ,这个需要配置在http里面的server外面,也就是和 server同级别
upstream windowsapp.com{ server 127.0.0.1:8050 weight=1; server 127.0.0.1:8060 weight=1; }
3. location 配置 proxy
location / { proxy_pass http://windowsapp.com; }
这时候,你访问 http://localhost:2016,有时候会访问的是 8050,有时候是 8060的网站了。
你修改完毕 conf文件后可能要重启,打开cmd
cd c:\nginx-1.9.9
nginx -s reload
执行完毕就Ok了。
静态文件缓存配置
1. 把 CSS 和 js以及图片拷贝到 c:\nginx-1.9.9\staticfiles
2. 在sever里面添加如下配置,重启 nginx,请注意下面是 root,
也就是说, scripts/jquery.js 会请求 /nginx-1.9.9/staticfiles/scripts/jquery.js,亲,小心哦。
你可以随便修改,配置一个错误的,你就会发现 js和css就请求不到了。
location ~ \.(css)$ { root /nginx-1.9.9/staticfiles/; expires 7d; } location ~ \.(js)$ { root /nginx-1.9.9/staticfiles/; expires 7d; }
这时候,你就已经缓存 js和css文件了,时间是7d。
