  • nginx之配置文件公用抽取

    nginx之配置文件公用抽取

    因为某些原因，需要同时部署同一应用两个不同分支的代码，而配置文件存在较大重复，因此有此篇。

    最近构建的过程中遇到了一些跟nginx配置相关的问题，记录下。

    简单说下构建的状况：前后端分离，jenkins + jar包+nginx部署前端。

}

    刚开始的时候只监听了8888端口（后端端口8081,8082），用来构建dev分支代码。后来，需要构建出一个新的分支，又不能影响dev分支。因此新增一个7777端口进行监听（后端对应端口8087），两个server除了端口不同外就只有proxy_pass对应的地址不同，html的地址不同，因此，考虑将相同部分抽出来。

    在conf同级新建conf.d文件夹，新建dev.conf和performance.conf

    server {
        listen       8888;
        server_name  localhost;
        # 上传文件大小限制100M
        client_max_body_size 100m;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
            add_header BackendIP "$upstream_addr;" always;

        set $ROOT_HTML /opt/soft/applicationName/backend/ui/html;
        set $SERVER_URL applicationName_server;
        include common-route.conf;


    }


    server {
        listen       7777;
        server_name  localhost;
        # 上传文件大小限制100M
        client_max_body_size 100m;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
            add_header BackendIP "$upstream_addr;" always;

        set $ROOT_HTML /opt/soft/applicationName/backend/ui/otherhtml;
        set $SERVER_URL 127.0.0.1:8087;
        include common-route.conf;



    }

    这里将原本两个不同点通过设置ROOT_HTML和SERVER_URL来解决。其余的内容放到conf文件夹下的common-router.conf中

        server 127.0.0.1:8082;
    }


    include /usr/local/nginx/conf.d/*.conf;



}

    虽然上面的配置平平无奇，不过走向正确配置的道路还是遇到了些波折。

    • conf.d文件夹下的两个conf文件的include文件的路径问题，..啥的用不了，反倒是看起来不正确的 include common-route.conf;能够正确引用。另一点是，common-route.conf不能放到conf.d下面，报的错忘了什么了。

    • 原先conf.dconf文件的SERVER_URL是这样的http://applicationName_server，后来报了invalid port，把http://去掉放到具体的server里面了。

    • 单值代码加载，在未做改造前这样

      location /applicationName/artery/code {
		   proxy_pass http://applicationName_server/applicationName/code/;
		   add_header 'Cache-Control' 'no-cache';
		   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;
		}

      第一次改造

      location /applicationName/artery/code {
                  
                  
	proxy_pass http://$SERVER_URL/applicationName/code/;

    add_header 'Cache-Control' 'no-cache';
    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;
}

      这种直接404，而如果把$SERVER_URL改成具体的后端地址，则7777和8888端口中有一个可以正常访问单值代码。谷歌的几个方案都说是什么resolver的问题，但照着改还是不工作

      再后来改造使用rewrite来改写path

         location /applicationName/artery/code {
                   
                rewrite  ^/(.*)/code/(.*)$ /applicationName/code/$2  permanent;
                   
                   add_header 'Cache-Control' 'no-cache';
                   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;
                }

      路径倒是改了（忽略上面的$2，去掉第一个括号可以改成$1），可applicationName/code又404了。然后又加上了/applicationName/code的location配置

      location /applicationName/artery/code {
                   #return 200 http://$SERVER_URL/applicationName/code;
                rewrite  ^/(.*)/code/(.*)$ /applicationName/code/$2  permanent;
                   #proxy_pass $CODE_URL;
                   #proxy_pass http://$SERVER_URL/applicationName/code/;
                   #proxy_pass http://127.0.0.1:8087/applicationName/code/;
                   add_header 'Cache-Control' 'no-cache';
                   proxy_set_header Host             $http_host;
                   proxy_set_header X-Real-IP        $remote_addr;
                   proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
                }
                location /applicationName/code {
                   proxy_pass http://$SERVER_URL;
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;
                }

    最后，附个conf的目录结构

    当你准备好了，机会来临的时候，你才能抓住
