## Description¶

condor_configure and condor_install refer to a single script that installs and/or configures HTCondor on Unix machines. As the names imply, condor_install is intended to perform a HTCondor installation, and condor_configure is intended to configure (or reconfigure) an existing installation. Both will run with Perl 5.6.0 or more recent versions.

condor_configure (and condor_install) are designed to be run more than one time where required. It can install HTCondor when invoked with a correct configuration via

condor_install


or

condor_configure --install


or, it can change the configuration files when invoked via

condor_configure


Note that changes in the configuration files do not result in changes while HTCondor is running. To effect changes while HTCondor is running, it is necessary to further use the condor_reconfig or condor_restart command. condor_reconfig is required where the currently executing daemons need to be informed of configuration changes. condor_restart is required where the options –make-personal-condor or –type are used, since these affect which daemons are running.

Running condor_configure or condor_install with no options results in a usage screen being printed. The –help option can be used to display a full help screen.

Within the options given below, the phrase release directories is the list of directories that are released with HTCondor. This list includes: bin, etc, examples, include, lib, libexec, man, sbin, sql and src.

## Options¶

-help

Print help screen and exit

-usage

Print short usage and exit

-install

Perform installation, assuming that the current working directory contains the release directories. Without further options, the configuration is that of a Personal HTCondor, a complete one-machine pool. If used as an upgrade within an existing installation directory, existing configuration files and local directory are preserved. This is the default behavior of condor_install.

-install-dir=<path>

Specifies the path where HTCondor should be installed or the path where it already is installed. The default is the current working directory.

-prefix=<path>

This is an alias for -install-dir.

-local-dir=<path>

Specifies the location of the local directory, which is the directory that generally contains the local (machine-specific) configuration file as well as the directories where HTCondor daemons write their run-time information (spool, log, execute). This location is indicated by the LOCAL_DIR variable in the configuration file. When installing (that is, if -install is specified), condor_configure will properly create the local directory in the location specified. If none is specified, the default value is given by the evaluation of $(RELEASE_DIR)/local.$(HOSTNAME).

During subsequent invocations of condor_configure (that is, without the -install option), if the -local-dir option is specified, the new directory will be created and the log, spool and execute directories will be moved there from their current location.

-make-personal-condor

Installs and configures for Personal HTCondor, a fully-functional, one-machine pool.

-bosco

Installs and configures Bosco, a personal HTCondor that submits jobs to remote batch systems.

-type= < submit, execute, manager >

One or more of the types may be listed. This determines the roles that a machine may play in a pool. In general, any machine can be a submit and/or execute machine, and there is one central manager per pool. In the case of a Personal HTCondor, the machine fulfills all three of these roles.

-central-manager=<hostname>

Instructs the current HTCondor installation to use the specified machine as the central manager. This modifies the configuration variable COLLECTOR_HOST to point to the given host name. The central manager machine’s HTCondor configuration needs to be independently configured to act as a manager using the option -type=manager.

-owner=<ownername>

Set configuration such that HTCondor daemons will be executed as the given owner. This modifies the ownership on the log, spool and execute directories and sets the CONDOR_IDS value in the configuration file, to ensure that HTCondor daemons start up as the specified effective user. This is only applicable when condor_configure is run by root. If not run as root, the owner is the user running the condor_configure command.

-maybe-daemon-owner

If -owner is not specified and no appropriate user can be found to run Condor, then this option will allow the daemon user to be selected. This option is rarely needed by users but can be useful for scripts that invoke condor_configure to install Condor.

-install-log=<file>

Save information about the installation in the specified file. This is normally only needed when condor_configure is called by a higher-level script, not when invoked by a person.

-overwrite

Always overwrite the contents of the sbin directory in the installation directory. By default, condor_install will not install if it finds an existing sbin directory with HTCondor programs in it. In this case, condor_install will exit with an error message. Specify -overwrite or -backup to tell condor_install what to do.

This prevents condor_install from moving an sbin directory out of the way that it should not move. This is particularly useful when trying to install HTCondor in a location used by other things (/usr, /usr/local, etc.) For example: condor_install -prefix=/usr will not move /usr/sbin out of the way unless you specify the -backup option.

The -backup behavior is used to prevent condor_install from overwriting running daemons - Unix semantics will keep the existing binaries running, even if they have been moved to a new directory.

-backup

Always backup the sbin directory in the installation directory. By default, condor_install will not install if it finds an existing sbin directory with HTCondor programs in it. In this case, condor_install with exit with an error message. You must specify -overwrite or -backup to tell condor_install what to do.

This prevents condor_install from moving an sbin directory out of the way that it should not move. This is particularly useful if you’re trying to install HTCondor in a location used by other things (/usr, /usr/local, etc.) For example: condor_install -prefix=/usr will not move /usr/sbin out of the way unless you specify the -backup option.

The -backup behavior is used to prevent condor_install from overwriting running daemons - Unix semantics will keep the existing binaries running, even if they have been moved to a new directory.

-ignore-missing-libs

Ignore missing shared libraries that are detected by condor_install. By default, condor_install will detect missing shared libraries such as libstdc++.so.5 on Linux; it will print messages and exit if missing libraries are detected. The -ignore-missing-libs will cause condor_install to not exit, and to proceed with the installation if missing libraries are detected.

-force

This is equivalent to enabling both the -overwrite and -ignore-missing-libs command line options.

-no-env-scripts

By default, condor_configure writes simple sh and csh shell scripts which can be sourced by their respective shells to set the user’s PATH and CONDOR_CONFIG environment variables. This option prevents condor_configure from generating these scripts.

-env-scripts-dir=<directory>

By default, the simple sh and csh shell scripts (see -no-env-scripts for details) are created in the root directory of the HTCondor installation. This option causes condor_configure to generate these scripts in the specified directory.

-credd

Configure the the condor_credd daemon (credential manager daemon).

-verbose

Print information about changes to configuration variables as they occur.

## Exit Status¶

condor_configure will exit with a status value of 0 (zero) upon success, and it will exit with a nonzero value upon failure.

## Examples¶

Install HTCondor on the machine (machine1@cs.wisc.edu) to be the pool’s central manager. On machine1, within the directory that contains the unzipped HTCondor distribution directories:

% condor_install --type=submit,execute,manager


This will allow the machine to submit and execute HTCondor jobs, in addition to being the central manager of the pool.

To change the configuration such that machine2@cs.wisc.edu is an execute-only machine (that is, a dedicated computing node) within a pool with central manager on machine1@cs.wisc.edu, issue the command on that machine2@cs.wisc.edu from within the directory where HTCondor is installed:

% condor_configure --central-manager=machine1@cs.wisc.edu --type=execute


To change the location of the LOCAL_DIR directory in the configuration file, do (from the directory where HTCondor is installed):

% condor_configure --local-dir=/path/to/new/local/directory


This will move the log,spool,execute directories to /path/to/new/local/directory from the current local directory.
