Chapter 4

Using Silent Installation

Silent installation is intended for use at sites where many server instances must be created. For Directory Server, it is especially useful for heavily replicated sites that will create a large number of consumer servers.

To use silent installation, you create a silent installation file, supply values for the appropriate installation directives, and run the program with the setup -s and -f command-line options.

The procedure below explains how to use silent installation:

On Windows machines, log in with Administrator privileges. On UNIX machines, log in as root.
Create a new directory:

# mkdir ds
# cd ds
If you have not already done so, download the product binaries file to the installation directory.
On Windows machines, unzip the product binaries. On UNIX, unpack the product binaries file using the following command:

# gunzip -dc filename .tar.gz | tar -xvof-

where filename corresponds to the product binaries file that you want to unpack.
Prepare the file that will contain your installation directives.

See Preparing Silent Installation Files for instructions and for some examples of the silent-install files.
Fill in appropriate values for the installation directives.

See Specifying Silent Installation Directives, for the complete list of silent installation directives that you can use when installing Directory Server.
Run the setup program with the -s and -f command-line options:

setup -s -f filename

where filename is the name of the file that contains your installation directives.

Preparing Silent Installation Files

The best way to create a file for use with silent installation is to use the setup program to interactively create a server instance of the type that you want to duplicate. To do this, run setup with the -k flag. The setup program will create the following file:

serverRoot/setup/install.inf

This file contains all the directives that you would use with silent installation to create the server instance. You can then use this file to create other server instances of that type.

You will have to make some modifications to this file before you use it. Specifically, ensure that you have done the following:

FullMachineName -- Set this directive to a value that is appropriate for the machine on which Directory Server will be installed if it's not to be the local machine. In most circumstances, it is best not to use this directive because FullMachineName will then default to the local host name. However, if you use custom installation to generate your initial server instance, then this directive will appear in the install.inf file.
ServerIpAddress -- Set this directive appropriate for the local machine. The same usage rules apply for ServerIpAddress as for FullMachineName. Specifically, try not to include ServerIpAddress in your install.inf file unless you absolutely have to (as may be necessary for multi-homed systems).
ServerRoot -- Verify the installation path on this directive. If you are installing on both Windows and UNIX machines, make sure the appropriate path delimiter is used. Add or remove the Windows drive letter designation as is appropriate for the host you are installing on. Also, the name of the file-system directory where you install files must not contain any space characters.
ServerIdentifier -- If you are installing more than one Directory Server on the same host, make sure that this directive contains a unique value for each server instance.
SuiteSpotUserID and SuiteSpotGroup -- If you create your install.inf file on a Windows machine, then the SuiteSpotUserID and SuiteSpotGroup directives are both set to nobody. If you subsequently use this file on a UNIX machine, ensure the user and group specified by these directives are appropriate for the machine. The SuiteSpotUserID and SuiteSpotGroup directives determine what user and group a server will run under when installed on a UNIX system.

Note

Be sure to protect your install.inf files because they contain passwords in clear. Also ensure that any DNs in these files are in the UTF-8 character set encoding.

The sections that follow provide examples of using silent installation to support the following installation scenarios:

You can find a definition of the individual installation directives in Specifying Silent Installation Directives.

Note

The silent.inf file provided with the Directory Server is merely a template, an example of how to write your own. For the file to work, many of the parameters (host name, ports, paths, and so on) in the file must be replaced with appropriate values.

It is also easy to generate your own silent installation file using the setup -k option and modify the resulting install.inf file as needed.

Specifying Silent Installation Directives

This section describes the basic format of the file used for silent installation. It then describes the directives that are available for each area of the silent installation file.

Silent Installation File Format

When you use silent installation, you provide all the installation information in a file. This file is formatted as follows:

       [General] 
    

       directive=value
      
    

       directive=value
      
    

       directive=value
      
    

...

       
[slapd]

       directive=value
      
    

       directive=value
      
    

       directive=value
      
    

...

       
[admin]

       directive=value
      
    

       directive=value
      
    

       directive=value
      
    

...

       
[Base]

       directive=value
      
    

       directive=value
      
    

       directive=value
      
    

...

The keywords [General], [slapd], and [admin] are required. They indicate that the directives that follow are meant for a specific aspect of the installation. They must be provided in the file in the order indicated above.

[General] Installation Directives

[General] installation directives specify information of global interest to the Netscape servers installed at your site. That is, the information you provide here will be common to all your Netscape servers.

The [General] installation directives are listed in Table 4-1.

Table 4-1 [General] Installation Directives


Directive	Description
Components	Specifies components to be installed. The list of available components will differ depending on the Netscape servers available on your installation media. For standalone directory installation, the list of components is: svrcore -- Uninstallation binaries base -- The base installation package admin -- The Administration Server binaries slapd -- The Directory Server binaries This directive is required. At a minimum, you should always provide: components= svrcore,base,admin
ServerRoot	Specifies the full path to the directory where the Netscape server binaries are installed. This directive is required.
FullMachineName	Specifies the fully qualified domain name of the machine on which you are installing the server. The default is the local host name.
SuiteSpotUserID	UNIX only. Specifies the user name as which Netscape servers will run. This parameter does not apply to the user as which the Administration Server runs. See the SysUser directive in Table 4-3 for more information. The default is user nobody, but this should be changed for most deployments.
SuiteSpotGroup	UNIX only. Specifies the group as which Netscape servers will run. The default is group nobody, but this should be changed for most deployments.
ConfigDirectoryLdapURL	Specifies the LDAP URL that is used to connect to your configuration directory. LDAP URLs are described in the Netscape Directory Server Administrator's Guide. This directive is required.
AdminDomain	Specifies the administration domain under which this server will be registered. See Determining the Administration Domain for more information about administration domains.
ConfigDirectoryAdminID	Specifies the user ID of the entry that has administration privileges to the configuration directory. This directive is required.
ConfigDirectoryAdminPwd	Specifies the password for the ConfigDirectoryAdminID. This directive is required.
UserDirectoryLdapURL	Specifies the LDAP URL that is used to connect to the directory where your user and group data are stored. If this directive is not supplied, the configuration directory is used for this purpose. LDAP URLs are described in the Netscape Directory Server Administrator's Guide.
UserDirectoryAdminID	Specifies the user ID of the entry that has administration privileges to the user directory.
UserDirectoryAdminPwd	Specifies the password for the UserDirectoryAdminID.

[slapd] Installation Directives

[slapd] installation directives specify information of interest only to the Directory Server instance that you are currently installing. These directives are classified as follows:

Required [slapd] Installation Directives -- You must provide these directives when you use silent installation with Directory Server.
Optional [slapd] Installation Directives -- You may provide these directives when you use silent installation with Directory Server.

Table 4-2 lists the directives.

Table 4-2 Required and Optional [slapd] Installation Directives


Required Directive	Description
Components	Specifies the slapd components to be installed. The components are: slapd -- Install Directory Server. slapd-client -- Install Directory Server Console. This directive is required. It is recommended that you always install both components any time you install the Directory Server.
ServerPort	Specifies the port the server will use for LDAP connections. For information on selecting server port numbers, see Choosing Unique Port Numbers. This directive is required.
ServerIdentifier	Specifies the server identifier. This directive is required. This value is used as part of the name of the directory in which the Directory Server instance is installed. For example, if your machine's host name is phonebook, then this name is the default and selecting it will cause the Directory Server instance to be installed into a directory labeled slapd-phonebook.
Suffix	Specifies the suffix under which you will store your directory data. For information on suffixes, see Determining Your Directory Suffix. This directive is required.
RootDN	Specifies the distinguished name used by the directory manager. For information on the directory manager, see Defining Authentication Entities. This directive is required.
RootDNPwd	Specifies the directory manager's password. This directive is required.
Optional Directive	Description
AddSampleEntries	If set to yes, this directive causes the example.ldif sample directory to be loaded. Use this directive if you are installing the Directory Server for evaluation purposes and you do not already have an LDIF file to populate your directory with. Default is no.
AddOrgEntries	If set to yes, this directive causes the new Directory Server instance to be created with a suggested directory structure and access control. If this directive is used and InstallLdifFile is also used, then this directive has no effect. Default is no.
InstallLdifFile	Causes the contents of the LDIF file to be used to populate your directory.

[admin] Installation Directives

[admin] installation directives specify information of interest only to your Directory Server's Administration Server. That is, this is the installation information required for the Administration Server that is used to manage the Directory Server instance that you are currently installing.

The [admin] installation directives are listed in Table 4-3.

Table 4-3 [admin] Installation Directives


Directive	Description
Components	Specifies the admin components to be installed. The base components are: admin -- Install Administration Server. You must install the Administration Server if you are also installing some other Netscape server. admin-client -- Install Netscape Console. Specify just this component if you are installing Netscape Console as stand-alone. Do not install this component if you will remotely manage your servers and Netscape Console will be installed somewhere else on your network.
SysUser	UNIX only. Specifies the user that the Administration Server will run as. For default installations that use the default Netscape port numbers, this user must be root. root is the default. For information on what users your servers should run as, see Deciding the User and Group for Your Netscape Servers (UNIX only)
Port	Specifies the port that the Administration Server will use. Note that the Administration Server's host name is given by the FullMachineName directive. For more information on FullMachineName, see Table 4-1.
ServerAdminID	Specifies the administration ID that can be used to access this Administration Server if the configuration directory is not responding. The default is to use the value specified by the ConfigDirectoryAdminID directive. See Defining Authentication Entities for information on this directive.
ServerAdminPwd	Specifies the password for ServerAdminID.
ServerIpAddress	Specifies the IP address that the Administration Server will listen to. Use this directive if you are installing on a multi-homed system and you do not want to use the first IP address for your Administration Server.

[Base] Installation Directives

There is only one [Base] installation directive, and it allows you to determine whether Netscape Console is installed. Table 4-4 lists the directive.

Table 4-4 [Base] Installation Directive


Directive	Description
Components	Specifies the base components to be installed. The base components are: base -- Install the shared libraries used by all Server Consoles. You must install this package if you are also installing some other Netscape server. base-client -- Install the Java run time environment used by the Server Consoles. base-jre -- Causes the Java run time environment to be installed. This directive is required if you are installing a Netscape server (versus just Netscape Console). You must install both packages when you are installing a Netscape server.

[nsperl] Installation Directives

There is only one [nsperl] installation directive and it allows you to determine whether nsPerl is to be installed. Table 4-5 lists the directive.

Table 4-5 [nsperl] Installation Directive


Directive	Description
Components	Specifies whether nsperl that is bundled with Directory Server is to be installed. This nsPerl is CPAN perl, built and maintained for use by Netscape server products. nsperl561 -- Install nsPerl version 5.6.1. This directive is required if you are installing a Netscape server (versus just Netscape Console).

[perldap] Installation Directives

There is only one [perldap] installation directive, and it allows you to determine whether PerLDAP is to be installed. Table 4-6 lists the directive.

Table 4-6 [perldap] Installation Directive


Directive	Description
