Apache HTTP Server is an open source HTTP web server for UNIX-like systems (BSD, Linux, and UNIX), Microsoft Windows, and other platforms.
DreamHost customers have only limited access to Apache settings on shared servers (via the panel). For example, certain options can be changed through the Remap Sub-directories page at Remap Sub-Dir and .htaccess files.
DreamHost Apache version
DreamHost runs the following versions:
- 2.2.31 on servers running Ubuntu 14 (Trusty)
- 2.4.29 on servers running Ubuntu 18 (Bionic)
- 2.4.25 on servers running Debian (Stretch)
In the past, one could determine information about the web server from the HTTP response headers through the "Server" header. However for security reasons, it was decided to set ServerTokens to "Prod" and as a result, the value of this header only returns "Apache". It cannot be modified through per-directory configuration files (.htaccess).
For example, in the past, running curl -Is to your site gives you the following response:
[server]$ curl -Is http://websitehelp.support | grep Server Server: Apache/1.3.37 (Unix) mod_throttle/3.1.2 DAV/1.0.3 mod_fastcgi/2.4.2 mod_gzip/126.96.36.199a PHP/4.4.7 mod_ssl/2.8.22 OpenSSL/0.9.7e
If you run this same command now, the only response is ‘Apache’:
[server]$ curl -Is http://websitehelp.support |grep Server Server: Apache
To find the version of Apache currently running on a Trusty machine, run the following:
[server]$ dpkg -l ndn-apache22
For Bionic and Debian machines, run the following:
[server]$ /usr/sbin/apache2 -v
Apache modules for DreamHost
If you need the xsendfile module enabled, you must contact support on the Contact Support page. Please be sure to mention on which domain you would like it enabled. Also, if you need the proxy module, that can only be enabled on a VPS or Dedicated server.
