We offer repositories for CentOS 5, 6, and 7. A user has also created a repository for Debian Wheezy.

CentOS 5, 6 & 7

Add the Repository

Use the following commands to add our CentOS repositories:

CentOS 5: rpm -ivh

CentOS 6: rpm -ivh

CentOS 7: rpm -ivh

Install OpenLiteSpeed

yum install openlitespeed

The above command installs the latest version of OpenLiteSpeed.

Using version numbers, for example yum install openlitespeed-1.2.1, will install older versions. 1.2.1 is the oldest version in the repository.

Note: The OpenLiteSpeed packages in our repositories have SPDY enabled. The binary also includes the OpenSSL library needed to run SPDY. You do not have to install OpenSSL 1.0.1 to use SPDY if you download the package from the repositories.

Note: To prevent users from mistakenly upgrading to a beta version, OpenLiteSpeed 1.4 has not yet been added to our repository. It will be added when it is no longer beta.

Getting Started

  • The default installation directory is /usr/local/lsws.
To start the server, simply run /usr/local/lsws/bin/lswsctrl start. (To stop it, run /usr/local/lsws/bin/lswsctrl stop.)
  • A sample site should be running on the server.
To access your site, point your browser to http://[address]:8088/, [address] being the IP address or domain name of your web server machine. Use "localhost" if the server is on the machine you are using. By default, OpenLiteSpeed runs on port "8088".
A congratulations page linked to other testing pages should load into the browser when pointed to the above address. If not, try testing the WebAdmin interface.
  • The default port for the WebAdmin console is 7080.
Plug https://[address]:7080/, into your browser to go to the WebAdmin interface.
Remember the "https://" and that for [address] you can use "localhost" if you're currently using the machine the server is on.
A login page should load. The defaults for the administrator's user name and password are "admin" and "123456".
For detailed information regarding configuration, please refer to our Configuration Guide, or click the "Help" link at the top of each page.
  • If your server uses a firewall, please make sure that localhost is trusted.
For instance, Linux with IPTables should include a rule ALLOW INPUT from LO.
  • If your website and the WebAdmin console are inaccessible, please take a look at the error log /usr/local/lsws/logs/error.log.
If there is a TCP port conflict with other server applications, you will need to stop the application currently running on port 7080. The following command can be used to check port 7080: netstat -an | grep 7080. If the port is available, the command will produce no output.
If the swapping directory is not writable, you can either grant writing permission for the swapping directory to the user whom the web server is running as, or change the swapping directory's configurations manually. The swapping directory is configured in the server's XML configuration file: /usr/local/lsws/conf/httpd_config.xml. Search the XML file for "swappingDir". The default location for the swapping directory is /tmp/lshttpd/swap.
If you still have problems with installation, please check the OpenLiteSpeed Development Group.


  • OpenLiteSpeed supports both native LiteSpeed XML configuration files and plain text configuration files (for those used to editing Apache's httpd.conf). Run /usr/local/lsws/conf/ to switch between these formats.

Debian Wheezy

Stefano Balocco has created a Debian Wheezy package of OpenLiteSpeed in his repository. (Thanks, Stefano!) You are welcome to try it out, though we make no guarantees about its efficacy or safety.
