    location ~ /issue([0-9]+) {
        return 301 http://example.com/shop/issues/custom_isse_name$1;
    }

Put this in your server directive:

    location /issue {
       rewrite ^/issue(.*) http://$server_name/shop/issues/custom_issue_name$1 permanent;
     }

Or duplicate it:

    location /issue1 {
       rewrite ^/.* http://$server_name/shop/issues/custom_issue_name1 permanent;
    }
    location /issue2 {
       rewrite ^.* http://$server_name/shop/issues/custom_issue_name2 permanent;
    }
     ...

If you need to duplicate more than a few redirects, you might consider using a map:

    # map is outside of server block
	map $uri $redirect_uri {
		~^/issue1/?$	http://example.com/shop/issues/custom_isse_name1;
		~^/issue2/?$	http://example.com/shop/issues/custom_isse_name2;
		~^/issue3/?$	http://example.com/shop/issues/custom_isse_name3;
		# ... or put these in an included file
	}

	location / {
		try_files $uri $uri/ @redirect-map;
	}

	location @redirect-map {
		if ($redirect_uri) {  # redirect if the variable is defined
			return 301 $redirect_uri;
		}
	}



I have an Apache server with a default configuration of Elasticsearch and everything works perfectly, except that the default configuration has a max size of 1GB.

I don&#39;t have such a large number of documents to store in Elasticsearch, so I want to reduce the memory.

I have seen that I have to change the `-Xmx` parameter in the Java configuration, but I don&#39;t know how.

I have seen I can execute this:

    bin/ElasticSearch -Xmx=2G -Xms=2G

But when I have to restart Elasticsearch this will be lost.

Is it possible to change max memory usage when Elasticsearch is installed as a service?

Is it possible to convert an `Uri` to `String` and vice versa?
Because I want to get the the `Uri` converted into `String` to pass into another activity via `intent.putextra()` and if it&#39;s not possible can anyone suggest me a way how to pass selected `Uri` into another activity?

I&#39;m in the process of reorganizing URL structure. 
I need to setup redirect rules for specific URLs - I&#39;m using Nginx. 

Basically Something like this:

    http://example.com/issue1 --&gt; http://example.com/shop/issues/custom_issue_name1
    http://example.com/issue2 --&gt; http://example.com/shop/issues/custom_issue_name2
    http://example.com/issue3 --&gt; http://example.com/shop/issues/custom_issue_name3

Thanks!

I&#39;ve tried adding the headers to the other location sections but the result is the same.

Any help appreciated!!


nginx add_header not working

I have a wildcard DNS set up so that all web requests to a custom domain (*.foo) map to the IP address of the Docker host.  If I have multiple containers running Apache (or Nginx) instances, each container maps the Apache port (80) to some external inbound port.

What I would like to do is make a request to container-1.foo, which is already mapped to the correct IP address (of the Docker host) via my custom DNS server, but proxy the default port 80 request to the correct Docker external port such that the correct Apache instance from the specified container is able to respond based on the custom domain.  Likewise, container-2.foo would proxy to a second container&#39;s apache, and so on.

Is there a pre-built solution for this, is my best bet to run an Nginx proxy on the Docker host, or should I write up a node.js proxy with the potential to manage Docker containers (start/stop/reuild via the web), or...?  What options do I have that would make using the Docker containers more like a natural event and not something with extraneous ports and container juggling?

Assigning vhosts to Docker ports

When I restart the nginx service on a command line on an Ubuntu server, the service crashes when a nginx configuration file has errors. On a multi-site server this puts down all the sites, even the ones without configuration errors.

To prevent this, I run the nginx configuration test first:

    nginx -t

After the test ran successful, I could restart the service:

    /etc/init.d/nginx restart

**Or** only reload the nignx site configs without a restart:

    nginx -s reload

Is there a way to combine those two commands where the restart command is conditional to the configuration test&#39;s result?

I couldn&#39;t find this online and [the official documentation][1] on this is rather basic. I don&#39;t know my way around Linux that well, so I don&#39;t know if what I&#39;m looking for is right in front of me or not possible at all.

I&#39;m using nginx v1.1.19.

How do I restart nginx only after the configuration test was successful on Ubuntu?

I am new to system administration. After installing nginx [via puppet][1] on Ubuntu I get the following output:

    [alert] could not open error log file: open() &quot;/var/log/nginx/error.log&quot; failed (13: Permission denied)
    
    [warn] 1898#0: the &quot;user&quot; directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
    
    [emerg] 1898#0: open() &quot;/var/log/nginx/access.log&quot; failed (13: Permission denied)

How do I get rid of all of these messages?

I don&#39;t want to use command line directly (chown / chmod) and repeat it every time I create a new server. Therefore, I am thinking of what has to be added to the puppet manifest.

What is the best sysadmin practice in this case: to change owner / permissions for /var/log/nginx or to store logs in different location? If chown / chmod is the way to go, which specific permissions would ensure the highest level of security?

I tried this, but it didn&#39;t help:

      file { &#39;/var/log/nginx&#39;:
        ensure  =&gt; directory,
        mode    =&gt; &#39;0755&#39;,
        owner   =&gt; &#39;www-data&#39;,
        group   =&gt; &#39;www-data&#39;,
        recurse =&gt; true
      }

Nginx: Permission denied for nginx on Ubuntu

I have Puma running as the upstream app server and Riak as my background db cluster. When I send a request that map-reduces a chunk of data for about 25K users and returns it from Riak to the app, I get an error in the Nginx log:

&gt;  upstream timed out (110: Connection timed out) while reading
&gt; response header from upstream

If I query my upstream directly without nginx proxy, with the same request, I get the required data. 

The Nginx timeout occurs once the proxy is put in. 

    **nginx.conf**
    
    http {
        keepalive_timeout 10m;
        proxy_connect_timeout  600s;
        proxy_send_timeout  600s;
        proxy_read_timeout  600s;
        fastcgi_send_timeout 600s;
        fastcgi_read_timeout 600s;
        include /etc/nginx/sites-enabled/*.conf;
    }
    
    **virtual host conf**
    
    upstream ss_api {
      server 127.0.0.1:3000 max_fails=0  fail_timeout=600;
    }
    
    server {
      listen 81;
      server_name xxxxx.com; # change to match your URL
    
      location / {
        # match the name of upstream directive which is defined above
        proxy_pass http://ss_api; 
        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;
        proxy_cache cloud;
        proxy_cache_valid  200 302  60m;
        proxy_cache_valid  404      1m;
        proxy_cache_bypass $http_authorization;
        proxy_cache_bypass http://ss_api/account/;
        add_header X-Cache-Status $upstream_cache_status;
      }
    }

Nginx has a bunch of timeout directives. I don&#39;t know if I&#39;m missing something important. Any help would be highly appreciated....



NGINX: upstream timed out (110: Connection timed out) while reading response header from upstream

So I know this may seem a little strange but I for sake of consistency, I would like all my urls to appear in this form: http://domain.com/page/ So far I have gotten the regular pages working but I cannot seem to get the error pages working properly.

If the user visits a page or directory that does not exist, I would like the browser to hard redirect to: http://domain.com/404/ This directory, however, will not actually exist. The real location of the error page will be under /pages/errors/404.php

Also, although I do not need an exact answer for all the various errors (400, 401, 403, 404, 500), I will be applying whatever method is given to redirect all of these to their &quot;proper&quot; URL&#39;s (eg. http://domain.com/400/ http://domain.com/500/ etc.)

Any ideas?

Rewrite URL after redirecting 404 error htaccess

I use [**NGINX**][1] in my dedicated server.

I&#39;ve a question about the **return** and **rewrite 301**.


----------


**Rewrite 301:**

    rewrite ^ http://xxx.xxxxx.net/xx-xxx/$request_uri? permanent;

**Return 301:**

    location ~ redirect-this/?$ {
        return 301 http://xxx.xxxxx.net/xx-xxx/redirect-this$1;
    }


----------


All redirects work correctly. But..

**Which is the most effective method to make a 301 redirect?**

I&#39;ve more than 200 url to redirect. So, what you recommend?


  [1]: http://nginx.org/

NGINX - Return 301 vs Rewrite

We have several rails apps under common domain in Docker, and we use nginx to direct requests to specific apps.

    our_dev_server.com/foo # proxies to foo app
    our_dev_server.com/bar # proxies to bar

Config looks like this:

    upstream foo {
      server foo:3000;
    }

    upstream bar {
      server bar:3000;
    }

    # and about 10 more...

    server {
      listen *:80 default_server;

      server_name our_dev_server.com;

      location /foo {
          # this is specific to asset management in rails dev
          rewrite ^/foo/assets(/.*)$ /assets/$1 break;
          rewrite ^/foo(/.*)$ /foo/$1 break;
          proxy_pass http://foo;
      }

      location /bar {
          rewrite ^/bar/assets(/.*)$ /assets/$1 break;
          rewrite ^/bar(/.*)$ /bar/$1 break;
          proxy_pass http://bar;
      }

      # and about 10 more...
    }

If one of these apps is not started then nginx fails and stops:

    host not found in upstream &quot;bar:3000&quot; in /etc/nginx/conf.d/nginx.conf:6

We don&#39;t need them all to be up but nginx fails otherwise.

Setup nginx not to crash if host in upstream is not found

In Magento CE, I&#39;d like to install an add-on to Extendware Page Cache called Lightening Cache.

It requires editing the Apache configuration inside the virtual host definition for the site, by adding:

    RewriteEngine On
    RewriteMap ewpchash prg:/home/.../shell/extendware/ewpagecache/apache/md5.php
    
    RewriteCond %{REQUEST_METHOD} !POST
    RewriteCond %{REQUEST_URI} !\.(js|css|png|jpg|jpeg|ico|gif)$ [NC]
    RewriteCond %{DOCUMENT_ROOT}%{SCRIPT_FILENAME} !-f
    RewriteCond ${ewpchash:%{HTTPS};~;%{HTTP_HOST};~;%{REQUEST_URI};~;%{QUERY_STRING};~;%{HTTP:Cookie};~;%{SCRIPT_FILENAME};~;%{REMOTE_ADDR};~;%{HTTP_USER_AGENT}} -f
    RewriteRule ^(.*)$ ${ewpchash:%{HTTPS};~;%{HTTP_HOST};~;%{REQUEST_URI};~;%{QUERY_STRING};~;%{HTTP:Cookie};~;%{SCRIPT_FILENAME};~;%{REMOTE_ADDR};~;%{HTTP_USER_AGENT}} [NC,L]
    &lt;FilesMatch &quot;\.(html)$&quot;&gt;
         Header unset Cache-Control
         Header unset Expires
         Header append Expires &quot;Thu, 19 Nov 1981 08:52:00 GMT&quot;
         Header append Cache-Control &quot;must-revalidate&quot;
    &lt;/FilesMatch&gt;

I have added this to the bottom of `/etc/apache2/sites-enabled/site.conf`.

When I run the command `apachectl graceful`, I receive the error:

&gt; AH00526: Syntax error on line 53 of
&gt; /etc/apache2/sites-enabled/site.conf: Invalid command &#39;Header&#39;,
&gt; perhaps misspelled or defined by a module not included in the server
&gt; configuration Action &#39;graceful&#39; failed. The Apache error log may have
&gt; more information.

Site is running Apache 2.4

Have I done something wrong?

Apache: edit to .conf file produces &quot;Invalid command &#39;Header&#39;&quot;

I need the Url Rewrite module on my IIS But it does not install and says that I need at least IIS7
