Installation of OpenLiteSpeed

The quick and easy way to install OpenLiteSpeed is through our OpenLiteSpeed repository. OpenLiteSpeed Installation can also be performed in a command line terminal as detailed below.

For testing purposes, OpenLiteSpeed can be installed into a home directory by a non-privileged user. For production use, it should be installed into a system directory which requires root access or using sudo).


OpenLiteSpeed requires pcre, expat, openssl, geoip, and zlib to be installed before you run the configure command. Our dependencies article gives steps for installing these packages in a number of different OSs.

Installation Steps

  • Download the package into a convenient location and decompress it.
  • Go to the installation directory, compile, and install the package as the root user (for production use):
cd openlitespeed-1.x.x
make && make install

Note1: A number of options and settings can be configured pre-installation. Use ./configure --help to see the configurable options.

  • By default, the Installer will install a sample site on port 8088 and set the WebAdmin console (the LiteSpeed GUI) to port 7080. (user: admin password: 123456)

Note2: On newer versions of OS X, you may have to use ./configure CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib --with-openssl=/opt/local as recent versions of OS X have deprecated usage of the OpenSSL library.

Note3: Check here on how to enable HTTP2 support during the configure.


If you run into errors or problems during installation, please consult our errors article for common problems.

Install PHP

OpenLiteSpeed use php build with LSAPI. For CentOS/Ubuntu/Debian, LSPHP can be installed through RPMS. If RPMS are not available for your system, such as FreeBSD and Mac OS, you may compile PHP by yourself.

Installing LSPHP via RPM

Installing LSPHP via APT

Compile PHP for LSWS

  • On CentOS, the shipped php binary /usr/local/lsws/fcgi-bin/lsphp can be run but it is only for testing purpose. On FreeBSD, Mac OS X, and Ubuntu the shipped PHP (for CentOS) will not run any all. On any case, you need to follow the above steps to setup PHP properyly.

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.


Uninstallation Steps

  • Stop OpenLiteSpeed if it is running: /usr/local/lsws/bin/lswsctrl stop
  • Remove the install directory: rm -rf /usr/local/lsws


You can change your OpenLiteSpeed version by simply installing a different version of OpenLiteSpeed. Re-installing will not affect your configuration files.
