    Each command line parameter is prefixed with <b>--</b>. If the command line
    parameter is prefixed with <b>++</b> then it's value will be appended to the
    existing option.
    If the environment variable with the same name as command line parameter but
    prefixed with <code>PR_</code> exists it will take precedence.
    For example:</p>
<source>set PR_CLASSPATH=xx.jar</source>

<p>is equivalent to providing</p>
<source>--Classpath=xx.jar</source>
<p> as command line parameter.</p>

<section name="Installing services">
<p>
The safest way to manually install the service is to use the provided
<b>service.bat</b> script. Administrator privileges are required to run this
script. If necessary, you can use the <code>/user</code> switch to specify
a user to use for the installation of the service.
</p>
<p>
<strong>NOTE:</strong> If User Account Control (UAC) is enabled you will be
asked for additional privileges when 'Tomcat<version-major/>.exe' is launched by
the script.<br/>
If you want to pass additional options to service installer as
<code>PR_*</code> environment variables, you have to either configure them
globally in OS, or launch the program that sets them with elevated privileges
(e.g. right-click on cmd.exe and select "Run as administrator"; on Windows 8
(or later) or Windows Server 2012 (or later), you can open an elevated command
prompt for the current directory from the Explorer
by clicking on the "File" menu bar). See issue <bug>56143</bug> for details.
</p>

<source>Install the service named 'Tomcat<version-major/>'
C:\> service.bat install</source>

<p>There is a 2nd optional parameter that lets you specify the name of the
service, as displayed in Windows services.</p>

<source>Install the service named 'MyService'
C:\> service.bat install MyService</source>

<p>When installing the service with a non-default name,
tomcat<version-major/>.exe and tomcat<version-major/>w.exe may be renamed to
match the chosen service name. To do this, use the <code>--rename</code>
option.</p>

<source>Install the service named 'MyService' with renaming
C:\> service.bat install MyService --rename</source>

<p>
If using tomcat<version-major/>.exe, you need to use the <b>//IS//</b> parameter.</p>

<source>Install the service named 'Tomcat<version-major/>'
C:\> tomcat<version-major/> //IS//Tomcat<version-major/> --DisplayName="Apache Tomcat <version-major/>" ^
     --Install="C:\Program Files\Tomcat\bin\tomcat<version-major/>.exe" --Jvm=auto ^
     --StartMode=jvm --StopMode=jvm ^
     --StartClass=org.apache.catalina.startup.Bootstrap --StartParams=start ^
     --StopClass=org.apache.catalina.startup.Bootstrap --StopParams=stop</source>

</section>
<section name="Updating services">
<p>
To update the service parameters, you need to use the <b>//US//</b> parameter.
</p>

<source>Update the service named 'Tomcat<version-major/>'
C:\> tomcat<version-major/> //US//Tomcat<version-major/> --Description="Apache Tomcat Server - https://tomcat.apache.org/ " ^
     --Startup=auto --Classpath=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar</source>

<p>If you gave the service an optional name, you need to specify it like this:
</p>

<source>Update the service named 'MyService'
C:\> tomcat<version-major/> //US//MyService --Description="Apache Tomcat Server - https://tomcat.apache.org/ " ^
     --Startup=auto --Classpath=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar</source>

</section>
<section name="Removing services">
<p>
To remove the service, you need to use the <b>//DS//</b> parameter.<br/>
If the service is running it will be stopped and then deleted.</p>

<source>Remove the service named 'Tomcat<version-major/>'
C:\> tomcat<version-major/> //DS//Tomcat<version-major/></source>

<p>If you gave the service an optional name, you need to specify it like this:
</p>

<source>Remove the service named 'MyService'
C:\> tomcat<version-major/> //DS//MyService</source>

</section>
<section name="Debugging services">
<p>
To run the service in console mode, you need to use the <b>//TS//</b> parameter.
The service shutdown can be initiated by pressing <b>CTRL+C</b> or
<b>CTRL+BREAK</b>.
If you rename the tomcat<version-major/>.exe to testservice.exe then you can just execute the
testservice.exe and this command mode will be executed by default.</p>

<source>Run the service named 'Tomcat<version-major/>' in console mode
C:\> tomcat<version-major/> //TS//Tomcat<version-major/> [additional arguments]
Or simply execute:
C:\> tomcat<version-major/></source>

</section>
<section name="Multiple Instances">
<p>
Tomcat supports installation of multiple instances. You can have a single
installation of Tomcat with multiple instances running on different IP/port
combinations, or multiple Tomcat versions, each running one or more instances on
different IP/ports.</p>
<p>
Each instance folder will need the following structure:
</p>
<ul>
<li>conf</li>
<li>logs</li>
<li>temp</li>
<li>webapps</li>
<li>work</li>
</ul>
<p>
At a minimum, conf should contain a copy of the following files from
CATALINA_HOME\conf\. Any files not copied and edited, will be picked up by
default from CATALINA_HOME\conf, i.e. CATALINA_BASE\conf files override defaults
from CATALINA_HOME\conf.</p>
<ul>
<li>server.xml</li>
<li>web.xml</li>
</ul>
<p>
You must edit CATALINA_BASE\conf\server.xml to specify a unique IP/port for the
instance to listen on. Find the line that contains
<code>&lt;Connector port="8080" ...</code> and add an address attribute and/or
update the port number so as to specify a unique IP/port combination.</p>
<p>
To install an instance, first set the CATALINA_HOME environment variable to the
name of the Tomcat installation directory. Then create a second environment
variable CATALINA_BASE and point this to the instance folder. Then run "service
install" command specifying a service name.</p>

<source>set CATALINA_HOME=c:\tomcat_<version-major/>
set CATALINA_BASE=c:\tomcat_<version-major/>\instances\instance1
service install instance1</source>

<p>
To modify the service settings, you can run <b>tomcat<version-major/>w //ES//instance1</b>.
</p>
<p>
For additional instances, create additional instance folder, update the
CATALINA_BASE environment variable, and run the service install again.</p>

<source>set CATALINA_BASE=c:\tomcat_<version-major/>\instances\instance2
service install instance2</source>
