&lt;h1&gt;Installation/Uninstallation&lt;/h1&gt;

&lt;h2&gt;Minimum system requirements&lt;/h2&gt;
&lt;ul&gt;
  &lt;li&gt;
    &lt;strong&gt;Operating System:&lt;/strong&gt;
	&lt;ul&gt;
      &lt;li&gt;Linux: kernel 2.4 and up, glibc-2.2 and up&lt;/li&gt;
      &lt;li&gt;CentOS: 5 and up&lt;/li&gt;
      &lt;li&gt;Ubuntu: 8.04 and up&lt;/li&gt;
      &lt;li&gt;Debian: 4 and up&lt;/li&gt;
      &lt;li&gt;AlmaLinux: 8 and up&lt;/li&gt;
      &lt;li&gt;Solaris: Sun0S 5.8 and up&lt;/li&gt;
      &lt;li&gt;FreeBSD: 4.5 and up&lt;/li&gt;
      &lt;li&gt;MacOSX: 10.3 and up&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;
    &lt;strong&gt;CPU:&lt;/strong&gt;
    &lt;ul&gt;
      &lt;li&gt;Intel: 80486 and up&lt;/li&gt;
      &lt;li&gt;PowerPC: PowerPC G4&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;&lt;strong&gt;Memory:&lt;/strong&gt; 32MB and up&lt;/li&gt;
  &lt;li&gt;
    &lt;strong&gt;Disk:&lt;/strong&gt;
    &lt;ul&gt;
      &lt;li&gt;Installation: 200MB&lt;/li&gt;
      &lt;li&gt;Runtime: 300MB and up, swapping space depends on usage.&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;Installation&lt;/h2&gt;

&lt;p&gt;
  Installation must be performed in a command line terminal. For testing
  purposes, LiteSpeed Web Server can be installed into a home directory by a
  non-privileged user. For production use, it should be installed into a system
  directory.
&lt;/p&gt;

&lt;p&gt;
  In Mac OS X, root user is disabled by default. It can be enabled using a
  series of actions detailed on the
  &lt;a href=&quot;https://support.apple.com/en-us/HT204012&quot;&gt;Apple&lt;/a&gt; website. You can
  also use the sudo command to install LSWS into a system directory without
  enabling the root user, but system folders will still only be manipulable by
  the root user. This means that every time you want to control LSWS from the
  command line terminal (like when you want to start or stop LSWS), you will
  have to use the sudo command.
&lt;/p&gt;

&lt;h3&gt;Installation Steps:&lt;/h3&gt;
&lt;ol&gt;
  &lt;li&gt; Decompress the package into a convenient location:&lt;br&gt;
    &lt;span class=&quot;cmd&quot;&gt;tar xvfz lsws-xxxx.tar.gz&lt;/span&gt; or
    &lt;span class=&quot;cmd&quot;&gt;gunzip -c lsws-xxxx.tar.gz | tar xvf -&lt;/span&gt;
    &lt;br /&gt;
  &lt;/li&gt;
  &lt;li&gt;
    &lt;span class=&quot;tag&quot;&gt;[Enterprise Edition Only]&lt;/span&gt; Install trial license
    key or serial number:
    &lt;ul&gt;
      &lt;li&gt;
        Trial License:
        &lt;p&gt;
          A trial license is for evaluation purposes and is only good for 15
          days after download. A trial license can be requested from download
          page.
        &lt;/p&gt;
        &lt;p&gt;
          A trial license key will be sent to you as an attachment in a
          confirmation email. Please save the attachment as
          &lt;span class=&quot;val&quot;&gt;trial.key&lt;/span&gt; and copy it to the installation
          directory.
        &lt;/p&gt;
        &lt;p&gt;
          When you switch from a trial license to a production license, you can
          simply run the install script again after following the steps below
          to update your license.
        &lt;/p&gt;
      &lt;/li&gt;
      &lt;li&gt;
        Production license:
        &lt;ol&gt;
          &lt;li&gt;
            Licenses can be leased or purchased at the LiteSpeed
            &lt;a href=&quot;https://store.litespeedtech.com/store/cart.php&quot;&gt;store&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            A serial number will be sent to you in the confirmation email after
            you order has been successfully processed. Each serial number
            allows for one server installation.
          &lt;/li&gt;
          &lt;li&gt;
            Save the serial number as &quot;serial.no&quot;; in the installation
            directory (where install.sh is located). The LiteSpeed products
            registration server will use this file to retrieve your license key
            during the installation process.
          &lt;/li&gt;
        &lt;/ol&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;
    &lt;p&gt;
      Go to the installation directory &lt;span class=&quot;cmd&quot;&gt;cd lsws-xxxx&lt;/span&gt;
      and run command &lt;span class=&quot;cmd&quot;&gt;./install.sh&lt;/span&gt; This will start
      LiteSpeed's Installer.
    &lt;/p&gt;
    &lt;p&gt;
      Note that only by running this command as the &amp;quot;root&amp;quot; user can
      you install the server into a system directory. Other users should
      install it to somewhere under their home directory.
    &lt;/p&gt;
    &lt;p&gt;
      Mac OS X users can install the server into a system directory with
      command &lt;span class=&quot;cmd&quot;&gt;sudo ./install.sh&lt;/span&gt;
    &lt;/p&gt;
  &lt;/li&gt;
  &lt;li&gt;
    Read the End User License Agreement and type &quot;Yes&quot; to confirm your
    agreement.
  &lt;/li&gt;
  &lt;li&gt;
    Specify the directory where you would like to install LiteSpeed Web Server.
    For the root user, the default is /usr/local/lsws. For non-privileged users,
    the default is their home directory. Remember, non-privileged users will
    not be able to install the server into a system directory.
  &lt;/li&gt;
  &lt;li&gt;
    &lt;span class=&quot;tag&quot;&gt;[Enterprise Edition Only]&lt;/span&gt;
    &lt;strong&gt;Generate license request.&lt;/strong&gt;
    &lt;p&gt;
      If the Installer only finds serial number but no valid license key, it
      will prompt to generate a license request. The installer will talk to
      LiteSpeed products registration server and obtain a valid license key
      automatically. Upon getting the license key, it will go to next step. If
      failed, the installer will exit and leave a license request file.
    &lt;/p&gt;
    &lt;p&gt;
      If the automatic process failed, you can create a ticket with license
      department from online store client area.
    &lt;/p&gt;
    &lt;p&gt;
      Note: Installation will continue only if there is a valid trial license
      or valid Enterprise license.
    &lt;/p&gt;
  &lt;/li&gt;
  &lt;li&gt;
    Follow the instructions on the screen. The Installer will ask you to set
    the following:
    &lt;ol&gt;
      &lt;li&gt;
        If a previously installed copy exists, the Installer will ask you to
        choose either upgrade, reinstall, or change directory. Upgrading will
        keep your current configurations.
      &lt;/li&gt;
      &lt;li&gt;
        Administrator's username and password for the WebAdmin interface.
      &lt;/li&gt;
      &lt;li&gt;What control panel, if any, you will use with LSWS.&lt;/li&gt;
      &lt;li&gt;User and group that the server process will run on behalf of.&lt;/li&gt;
      &lt;li&gt;TCP port for normal web service.&lt;/li&gt;
      &lt;li&gt;TCP port for WebAdmin interface. &lt;/li&gt;
      &lt;li&gt;Whether to set up LiteSpeed PHP.&lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;tag&quot;&gt;[Enterprise Edition Only]&lt;/span&gt; Root user has the
        option to enable chroot. The installer will setup the initial chroot
        environment automatically. Chroot is an advanced feature and your CGI
        may fail without configuration tuning. We strongly recommend not
        enabling chroot unless you are familiar with it. You can always enable
        it later by performing an upgrade installation.
      &lt;/li&gt;
    &lt;/ol&gt;
    &lt;p&gt;
      Finally, the Installer will ask you if you want to install the AWStats
      add-on module to keep track of your web statistics. Root user can also
      choose to run LiteSpeed Web Server automatically at system startup as a
      service. Then you're done! The installer can start up the server.
    &lt;/p&gt;
  &lt;/li&gt;
&lt;/ol&gt;

&lt;h3&gt;Testing Installation&lt;/h3&gt;
&lt;ol&gt;
  &lt;li&gt;
    For detailed information on controlling the server processes, please see
    the &lt;a href=&quot;admin.html&quot;&gt;Administration Guide&lt;/a&gt;. To start the server,
    simply run &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/bin/lswsctrl start&lt;/span&gt;.
  &lt;/li&gt;

  &lt;li&gt;
    To access your site, point your browser to
    &lt;span class=&quot;val&quot;&gt;http://[address]:8088/&lt;/span&gt;, [address] being the IP
    address or domain name of your web server machine. Use &quot;localhost&quot; if the
    server is on the machine you are using. &quot;8088&quot; is the default port. If you
    changed the port during installation, write the port you designated. A
    congratulations page should load into the browser. If not, try the WebAdmin
    interface.
  &lt;/li&gt;

  &lt;li&gt;
    The default port for the WebAdmin interface is 7080. Plug
    &lt;span class=&quot;val&quot;&gt;http://[address]:7080/&lt;/span&gt;, into your browser to go to
    the WebAdmin interface. (If you changed the port for WebAdmin during
    installation, use that port instead.) Remember that for [address] you can
    use &quot;localhost&quot; if you're using the machine the server is on. The
    administration interface welcome page should load. Click the &quot;Log on&quot; link
    and use the administrator's username and password specified during
    installation to log on. For detailed information regarding configuration,
    please refer to our &lt;a href=&quot;config.html&quot;&gt;Configuration Guide&lt;/a&gt;, or click
    the &quot;help&quot; link on top of each page.
  &lt;/li&gt;

  &lt;li&gt;
    If your server uses firewall, please make sure that localhost is trusted.
    For instance, Linux with IPTables should include a rule
    &lt;span class=&quot;cmd&quot;&gt;ALLOW INPUT from LO&lt;/span&gt;.
    &lt;br /&gt;
  &lt;/li&gt;

  &lt;li&gt;
    If your web site and the WebAdmin interface are inaccessible, please take a
    look at the error log -
    &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/logs/error.log&lt;/span&gt;
    &lt;ul&gt;
      &lt;li&gt;
        If there is a TCP port conflict with other server applications, the web
        server should be reinstalled with an available port.
        &lt;br /&gt;
        The following command can be used to find an available port:
        &lt;br /&gt;
        &lt;span class=&quot;cmd&quot;&gt;netstat -an | grep XXXX&lt;/span&gt;
        &lt;br /&gt;
        XXXX is a port number. If the port is available, the command will
        produce no output.
      &lt;/li&gt;

      &lt;li&gt;
        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 manually. The swapping
        directory is configured in the server's XML configuration file located
        at &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/conf/httpd_config.xml&lt;/span&gt;,
        default value is &lt;span class=&quot;cmd&quot;&gt;/tmp/lshttpd/swap&lt;/span&gt;. Search for
        &lt;span class=&quot;cmd&quot;&gt;&amp;lt;swappingDir&amp;gt;&lt;/span&gt;.
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
&lt;/ol&gt;

&lt;h2&gt;Upgrading&lt;/h2&gt;
&lt;p&gt;
  There are a few scenarios where you would need to update or upgrade the
  server:
&lt;/p&gt;

&lt;ul&gt;
  &lt;li&gt;A new release is available&lt;/li&gt;
  &lt;li&gt;Upgrade from a trial license to production license&lt;/li&gt;
  &lt;li&gt;Upgrade/downgrade to a different production license.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;
  There are a number of ways to upgrade. One way is to just run install.sh
  again and select &amp;quot;Upgrade&amp;quot; when prompted. Your current
  configurations will be kept.
&lt;/p&gt;

&lt;p&gt;
  Starting with release 2.0, version management can also be done from the
  WebAdmin Console interface, under Actions - Version Management. All your
  installed versions and the available new releases are listed here. You can
  install a new release or switch between different versions by clicking the
  appropriate link. Since release 2.0, LSWS also features a built-in update
  agent that will check for new releases periodically and send email
  notifications.
&lt;/p&gt;

&lt;p&gt;
  Starting with release 4.1, you can upgrade to the latest release, force
  reinstall, or downgrade to an old version using the command line tool
  lsup.sh. See detailed usage information in
  &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/admin/misc/lsup.sh --help&lt;/span&gt;
&lt;/p&gt;

&lt;p&gt;
  Since release 1.5.6, multiple versions of LiteSpeed Web Server can be
  installed. You can easily switch from one to another by using the version
  management utility:
  &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/admin/misc/mgr_ver.sh&lt;/span&gt;.
&lt;/p&gt;

&lt;ul&gt;
  &lt;li&gt;
    To switch to a version already installed, for example 1.5.6, just run
    &lt;span class=&quot;cmd&quot;&gt;
      [your_install_dir_current_version]/admin/misc/mgr_ver.sh 1.5.6
    &lt;/span&gt;
  &lt;/li&gt;

  &lt;li&gt;
    To remove previously installed files for a certain version, for example
    1.5.6, just run
    &lt;span class=&quot;cmd&quot;&gt;
      [your_install_dir_current_version]/admin/misc/mgr_ver.sh -d 1.5.6
    &lt;/span&gt;
  &lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;
  When upgrading your license (from trial to production license, for example),
  you can manually copy &quot;serial.no&quot; to the
  &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/conf/&lt;/span&gt; directory, then restart.
  Please backup your old serial number and license key before restart.
&lt;/p&gt;

&lt;h2&gt;License transfer procedure:&lt;/h2&gt;
&lt;p&gt;
  Please be aware that each license key is associated with a serial number and
  the server's hardware signature. A new key is required if a change in
  hardware signature is detected. So if you upgrade or change your hardware,
  you need to transfer your current production license in order to continue
  using the product.
&lt;/p&gt;

&lt;ol&gt;
  &lt;li&gt;
    To migrate your current license, you can simply run the server binary
    &lt;span class=&quot;cmd&quot;&gt;./lshttpd -m&lt;/span&gt;. It will talk to LiteSpeed' products
    registration server, unlock your serial number, and generate a temporary
    license key. This temporary key is good for 3 days. This allows you a
    smooth transition to the new server.
  &lt;/li&gt;

  &lt;li&gt;
    If you wish, you can take this chance to download the latest version of
    LiteSpeed Web Server to your new hardware. Then copy the serial number file
    &quot;serial.no&quot; to the installation directory and start up the Installer. You
    unlocked your serial number in the previous step, so running the Installer
    will get you a new license key.
  &lt;/li&gt;

  &lt;li&gt;
    If you wish to copy your old installation directory over to the new
    hardware, then you just need to activate your license. Run command
    &lt;span class=&quot;cmd&quot;&gt;./lshttpd -r&lt;/span&gt; to retrieve a new license key.
  &lt;/li&gt;

  &lt;li&gt;
    If the process fails, you can create a ticket with the license department
    in the &lt;a href=&quot;https://store.litespeedtech.com&quot;&gt;client area&lt;/a&gt; of the
    online store.
  &lt;/li&gt;
&lt;/ol&gt;

&lt;h2&gt;Uninstallation Steps&lt;/h2&gt;
&lt;ol&gt;
  &lt;li&gt;
    Simply run
    &lt;span class=&quot;cmd&quot;&gt;[your_install_dir]/admin/misc/uninstall.sh&lt;/span&gt; and
    follow the instructions on the screen.
  &lt;/li&gt;

  &lt;li&gt;
    The Uninstaller will ask the following questions:
    &lt;ul&gt;
      &lt;li&gt;whether to keep the log directory&lt;/li&gt;
      &lt;li&gt;whether to keep the configuration directory&lt;/li&gt;
    &lt;/ul&gt;
    &lt;br /&gt;
  &lt;/li&gt;

  &lt;li&gt;
    Directories that were not created by the Installer will not be touched,
    even if they are in [your_install_dir]. All the files created by the
    installer will be removed.
  &lt;/li&gt;
  &lt;li&gt;[your_install_dir] will be removed as well, if it is empty.&lt;/li&gt;
&lt;/ol&gt;&lt;/article&gt;&lt;div  class=&quot;ls-col-1-1&quot;&gt;&lt;footer class=&quot;copyright&quot;&gt;Copyright &amp;copy; 2003-2020. &lt;a href=&quot;https://www.litespeedtech.com&quot;&gt;LiteSpeed Technologies Inc.&lt;/a&gt; All rights reserved.&lt;/footer&gt;
