Background

I wrote this Inno Setup installer because I needed more functionality than was provided by the Apache Software Foundation (ASF) 32-bit/64-bit Windows service installer, which was built using NSIS. Specifically:

• The ASF installer doesn't provide an easy way to upgrade a Tomcat installation. Using the ASF installer, an upgrade consists of uninstall, click No when it asks if you want to delete all the files (a dangerous question), then install new version using the same options (hopefully you documented your settings). If you installed the service, you will need to reconfigure that as well. If you run the service using a specific account, you will need to specify it again and re-enter the credentials (because the uninstall deleted the service). Java runtime parameters (such as memory sizes, JVM options, etc.) must also be reconfigured.

• The installer-specific documentation is quite brief, and it doesn't mention some very peculiar command line parsing rules (e.g., the /D= command line option must be UPPER CASE and must not be quoted on the command line, even if the target directory name contains whitespace). The configuration options for a silent installation must sit in a text-based configuration file, and some notable Windows service configuration options are missing (service user account, etc.).

• The ASF installer doesn't set file system permissions for the service user account to actually be able to run any web applications because it doesn't have a way to specify the service user account name. This is a peculiar state of affairs when installing the Windows service: The service gets installed, but unless you run the service using the local system or an administrative account (not recommended), web applications won't work because the service user account doesn't have permission to write to the logs, temp, and work directories.

This custom Apache Tomcat Setup installer rectifies these limitations.

Reinstalling or Upgrading

Please note the following when using Setup to reinstall or upgrade Apache Tomcat:

• Setup won't overwrite files in the conf directory that are newer than the copies stored in Setup. This means that you can prevent accidental overwrites of customized files by updating them (open and save to update date and time, or use a "touch" utility) before reinstalling or upgrading.

• If the Windows service is installed, Setup can automatically stop the service, upgrade the binaries, and restart the service. All service installation details are retained when reinstalling or upgrading.

Setup Command Line Parameters

Common Command Line Parameters

/instancename="name"	Runs Setup to install a separate instance of Apache Tomcat. See Installing Separate Instances.
/dir="location"	Specifies the installation directory. The default location is d:\Program Files\Apache Tomcat (where d: is the Windows system partition).
/type=type	Specifies the installation type. See Setup Type and Components.
/components="componentlist"	Specifies the components Setup should install. See Setup Type and Components.
/group="name"	Specifies the Start Menu group name. The default group name is Apache Tomcat.
/noicons	Prevents creation of a Start Menu group.
/tasks="tasklist"	Specifies the tasks Setup should perform. See Setup Tasks.
/jvmpath="location"	Specifies the path and filename of the jvm.dll file. See Finding the jvm.dll File.
/silent	Runs Setup silently (i.e., without user interaction).
/log="filename"	Logs Setup activity to the specified file. The default is not to create a log file.

Windows Service Installation Command Line Parameters

The following command line parameters set the default values for the text boxes on the Select Service Configuration Options page and are applicable only when installing the Windows service:

Parameter	Description
/servicename=name	Specifies the Windows service name. This name cannot contain whitespace. The default is Tomcat.
/servicedisplayname="displayname"	Specifies the Windows service display name. The default is Apache Tomcat.
/serviceusername="username"	Specifies the name of the user account that will run the Windows service. The default is NT AUTHORITY\Local Service. For a local account, specify .\username. For a domain account, specify domainname\username.
/jvmoptions="options"	Specifies a semicolon-delimited list of additional JVM (Java Virtual Machine) options.
/jvmms=size	Specifies the initial memory pool size, in megabytes. The default size is 256.
/jvmmx=size	Specifies the maximum memory pool size, in megabytes. The default size is 256.

If the service user account requires a password, you must enter its password in the service configuration dialog after Setup completes.

IMPORTANT - It is not recommended to run the service using an administrative account or the LocalSystem account.

Instance Name Defaults

If you install a separate instance (see Installing Separate Instances), the default values of the /dir, /group, /servicename, and /servicedisplayname parameters will include the instance name. For example, if you specify /instancename="XWiki", the following will be defaults:

• /dir="d:\Program Files\Apache Tomcat - XWiki"
• /group="Apache Tomcat - XWiki"
• /servicename=Tomcat-XWiki
• /servicedisplayname="Apache Tomcat - XWiki"

Other Command Line Parameters

Setup is built using Inno Setup, so it supports the command line parameters common to all Inno Setup installers. Run Setup with the /? parameter for more details.

Administrative vs. Non-administrative Installation Mode

Setup supports both administrative and non-administrative installation modes:

• In administrative installation mode (the default), Setup installs Apache Tomcat for all users of the computer and allows installation of the Windows service.

• In non-administrative installation mode (not recommended), Setup installs Apache Tomcat in the current user's profile. To run Setup in non-administrative installation mode, you must specify the /currentuser parameter on Setup's command line. You cannot install the Windows service using non-administrative installation mode.

Installing Separate Instances

An instance is an independent installation of Apache Tomcat in a separate location. You can use the /instance command line parameter to install multiple Apache Tomcat services on the same computer, or if you need to run separate specific versions of Apache Tomcat.

If you install multiple instances, each installation is considered as a separate application. Each instance will appear as a separate entry in the installed application list in Windows. Each instance must be upgraded, reinstalled, or uninstalled separately. (That is, a reinstall, upgrade, or uninstall of a specific instance affects only that instance.)

Setup Type and Components

Setup's Select Components page allows selection of the setup type and components.

The setup type corresponds to the drop-down list on the Select Components page. Changing the drop-down list selection changes the selected components. The types are as follows:

Type	Name	Components Selected
Default installation	default	core,webapps/docs,webapps/manager
Core only	core	core
Full installation	full	Selects all components
Custom installation	custom	Selects a custom list of components

The /type command line parameter specifies a default setup type; e.g. /type=core specifies that Core only should be the default type.

The default is /type=default.

The components correspond to the checkboxes that represent individual components. The components are as follows:

Component	Name	Notes
Apache Tomcat core	core	Always selected
Web applications	webapps	Can't be selected alone
Documentation bundle	webapps/docs
Manager application	webapps/manager
Host Manager application	webapps/hostmanager
Examples	webapps/examples

The core component consists of the Apache Tomcat binaries and jar files.

The /components command line parameter is a comma-delimited list of components that should be selected by default. For example, /components="core,webapps/docs" selects the core and webapps/docs components by default. (This is equivalent to /components="webapps/docs" because the core component is always selected.)

The default is /components="core,webapps/docs,webapps/manager".

Setup Tasks

Setup's Select Additional Tasks page provides a list of additional tasks that Setup should perform:

Task	Name	Notes
Install Windows service	installservice
Set file system permissions for service user account	installservice/setpermissions	See Setting File System Permissions
Automatically start service when computer starts	installservice/setautostart
Create shortcut to start the service monitor at logon	installservice/startmonitoratlogon
Back up conf directory before installation	backupconf	See Backing Up the conf Directory

The /tasks parameter specifies which tasks are selected by default. Specifying an installservice subtask implies the installservice task (that is, /tasks="installservice/setautostart" is equivalent to /tasks="installservice,installservice/setautostart").

The default is /tasks="installservice/setpermissions,installservice/setautostart,backupconf".

Setting File System Permissions

The installservice/setpermissions task grants file system permissions to the account used to run the service, as follows:

• Apache Tomcat installation directory and subdirectories: Read-only

• logs, temp, and work directories: Modify

Web applications can start successfully with these minimum permissions.

If the service user account is not found, the permission changes will fail silently. In this case, you will need to grant the permissions manually.

IMPORTANT - You may need to change the permissions on one or more of the directories and/or files to properly secure the Apache Tomcat application. (For example, if you use SSL, you will most likely want to restrict access to the certificate's private key file.)

Backing Up the conf Directory

The backupconf task makes a backup copy of the conf directory if it exists (i.e., when reinstalling or upgrading). The backup directory will be named conf-backup-time (where time is the date and time the backup was created).

Finding the jvm.dll File

Apache Tomcat requires a Java Virtual Machine (JVM), so Setup needs to know the location of the jvm.dll file. Setup attempts to find it automatically in the following ways:

1. Setup searches the JavaSoft registry subkeys, if they exist, to find the RuntimeLib value (this value should contain the path to the jvm.dll file).

2. Setup searches the directory named in the JAVA_HOME or JRE_HOME environment variable for the jvm.dll file.

If you have a Java runtime installed and Setup fails to find it, you must specify the path to the jvm.dll file on the Select Java Virtual Machine page or by using the /jvmpath command line parameter.

Setup installs the 64-bit Apache Tomcat binaries if the jvm.dll file is 64-bit; otherwise Setup installs the 32-bit Apache Tomcat binaries.

Uninstalling Apache Tomcat

You can uninstall Apache Tomcat installed using Setup by using the standard Windows application management list. The uninstall process does not remove the conf directory or any files Setup did not install.

The uninstall program is located in the uninstall directory in the installation directory and is named uninsnnn.exe (where nnn is three digits, usually 000). Some common uninstall command line parameters are the following:

Parameter	Description
/silent	Runs the install silently (i.e., without user interaction).
/log="filename"	Logs uninstall activity to the specified file. The default is not to create a log file.

See the Inno Setup documentation for more uninstaller command line parameters.

Setup Limitations

• Setup doesn't provide a way to configure server port (server.xml) or Manager web application (tomcat-users.xml) details.

• Setup does not provide the ability to uninstall an upgrade (i.e., downgrade). To downgrade, you must first uninstall the current version and then install the desired version. For this reason, it is recommended to keep the Setup programs of previous versions available just in case.

Sample Command Line Parameters

/type=core
/serviceusername="FABRIKAM\AppService"
/jvmoptions="-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT"
/silent
/log="C:\Users\KenDyer\Documents\setup.log"

(All on one line)

These options perform a silent installation of Apache Tomcat. The service will run using the account FABRIKAM\AppService and will trust the Windows certificate store. Setup will log its activity to the specified log file.
