HTTPD with two different services in the same computer

I have a CentOS 6.9 server that is running a DokuWiki under HTTPD 2.2. This wiki is installed in /var/www/html/dokuwiki. Therefore, when you type myserver.com/dokuwiki, it enters the wiki. If you type myserver.com, a simple index.html file (/var/www/html/index.html) is shown with links to the Wiki and GitLab.

Now I have installed GitLab and configured it to also use HTTPD (by default it comes with NGINX integrated). Both GitLab and DokuWiki are working correctly if I launch them by themselves, but I cannot find the way to make them visible at the same time.

What I would like is: if the user types myserver.com, show the index.html with two links: one to the wiki (myserver.com/dokuwiki) and the other link to the GitLab server (myserver.com/gitlab). By clicking on each, the user can access the desired service.

What happens is that if put the configuration of gitlab with precedence over the other (by changing the name to 00-gitlab.conf, for example), the configuration of the wiki doesn't work and when you type either myserver.com or myserver.com/dokuwiki, it doesn't find anything ( Not found "/" is shown) because it uses the other rules and there is no match (due to the Location directive of GitLab, I guess). GitLab works OK in this case.

If I put the configuration of the Wiki with precedence, I get a 404 error when I try to access myserver.com/gitlab because this rule is more general and therefore it ignores the other with the Location directive. The Index and the Wiki work OK in this case.

Here are the Virtual Hosts configurations for both, stored in /etc/httpd/conf.d. Everything is SSL and it is working OK. The configuration for HTTP (port 80) is virtually the same but I did not include it here. I also have NameVirtualHost *:443 in httpd.conf.

Thanks.

Solution

  • I found the solution. I only need one VirtualHost and to correctly define my proxypass.

    Here's the working file:

    <VirtualHost *:443>
    ServerName myserver.com
    DocumentRoot /var/www/html
    SSLEngine on

    SSLProtocol all -SSLv2
    SSLHonorCipherOrder on
    SSLCipherSuite "ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS"
    Header add Strict-Transport-Security: "max-age=15768000;includeSubdomains"
    ServerSignature Off
    ProxyPreserveHost On
    AllowEncodedSlashes NoDecode

    SSLCertificateFile /etc/httpd/ssl/myserver.com.crt
    SSLCertificateKeyFile /etc/httpd/ssl/myserver.com.key

    Alias /gitlab  /opt/gitlab/embedded/service/gitlab-rails/public
    <Location /gitlab>
        Order deny,allow
        Allow from all

        ProxyPass http://127.0.0.1:8181
        ProxyPassReverse http://127.0.0.1:8181
        ProxyPassReverse http://myserver.com/gitlab
        RewriteEngine on

        RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f [OR]
        RewriteCond %{REQUEST_URI} ^/uploads/.*
        RewriteRule .* http://127.0.0.1:8181%{REQUEST_URI} [P,QSA,NE]

        ErrorDocument 503 /503.html
  </Location>
