...

  • --home
    • Specifies the directory in which the Agent should be installed.
  • --data
    • Specifies the directory in which Agent data such as configuration files should be stored.
    • By default the <home>/var_<http-port> directory is used, see options --home and --http-port.
  • --config
    • Specifies the directory from which the Agent reads configuration files.
    • By default the <data>/config directory is used, see option --data.
  • --logs
    • Specifies the directory to which the Agent stores log files.
    • By default the <data>/logs directory is used, see option --data.
  • --work
    • Specifies the working directory of the Agent.
    • By default the <data> directory is used, see option --data.
  • --user
    • Specifies the user account for the Agent daemon.
    • By default the account of the user running the Agent Installation Script is used.
  • --release
    • Specifies a release number such as 2.3.1 for download from the SOS web site if the --tarball option is not used.
  • --tarball
    • Optionally specifies the path to a .tar.gz file that holds the Agent installation or patch files. If this option is not used the installation or patch tarball will be downloaded from the SOS web site for the release indicated with the --release option.
    • Download is performed with curl that considers http_proxy and https_proxy environment variables and respective settings from a .curlrc file.
  • --patch
    • A patch is identified by an issue key in the Change Management System, for example JS-1984.
    • Patches are downloaded from the SOS web site if the --tarball option is not used.
    • Patches are added to the Agent's <home>/lib/patches directory. Note that the patches sub-directory will be emptied when updating an Agent installation later on.
    • If a backup directory is specified then an Agent's existing installation directory will be added to a .tar.gz backup file in this directory.
  • --jar
    • Optionally specifies the path to a .jar file that holds the patch.
  • --http-port
    • Specifies the HTTP port that the Agent is operated for. The default value is 4445. The Agent by default makes use of a configuration directory ./var_<http-port> that will be excluded from a backup taken with the --backup-dir option. In addition the HTTP port is used to identify the Agent Instance Start Script typically available from the ./bin/agent_<http-port>.sh script and to specify the value of the JS7_AGENT_HTTP_PORT environment variable in the script.
    • The port can be prefixed by the network interface, for example localhost:4445.
    • When used with the --restart switch the HTTP port is used to identify if the Agent is running.
  • --https-port
    • Specifies the HTTPS port that the Agent is operated for. The HTTPS port is specified in the Agent Instance Start Script typically available from the ./bin/agent_<http-port>.sh script with the environment variable JS7_AGENT_HTTPS_PORT. Use of HTTPS requires a keystore and truststore to be present, see --keystore and --truststore options.
    • The port can be prefixed by the network interface, for example batch.example.com:4445.
  • --pid-file-dir
    • Specifies the directory to which the Agent stores its PID file. By default the <data>/logs directory is used.
    • When using SELinux then it is recommended to specify the /var/run directory, see JS7 - How to install for SELinux.
  • --pid-file-name
    • Specifies the name of the PID file. By default the file name agent.pid is used.
    • The PID file is created in the directory specified by the --pid-file-dir option.
  • --instance-script
    • Specifies the path to an Instance Start Script that acts as a template and that is copied to the bin directory. Typically the name agent_<http-port>.sh. is used. Users are free to choose any name for the Instance Start Script. The script has to be executable for the Agent daemon, see --user option. Permissions of the script are not changed by the Agent Installation Script.
    • The Agent Installation Script will perform replacements in the Instance Start Script template for known placeholders such as <JS7_AGENT_USER>, for details see ./bin/agent_instance.sh-example.
  • --backup-dir
    • If a backup directory is specified then an Agent's existing installation directory will be added to a .tar.gz file in this directory.
    • File names are created according to the pattern: backup_js7_agent.<hostname>.<release>.<yyyy>-<MM>-<dd>T<hh>-<mm>-<ss>.tar.gz
    • For example: backup_js7_agent.centostest_primary.2.3.1.2022-03-19T20-50-45.tar.gz
  • --log-dir
    • If a log directory is specified then the Agent Installation Script will log information about processing steps in a log file in this directory.
    • File names are created according to the pattern: install_js7_agent.<hostname>.<yyyy>-<MM>-<dd>T<hh>-<mm>-<ss>.log
    • For example: install_js7_agent.centostest_primary.2022-03-19T20-50-45.log
  • --exec-start
    • This option can be used should the Agent be started after installation. For example, when using systemd then the option --exec-start="StartService" will start the Agent service provided that the related systemd service has been created manually or by use of the --make-service switch. Alternatively users can specify individual commands, for example --exec-start="sudo systemctl start js7_agent_4445".
    • For systemd service files see the JS7 - systemd Service Files for automated Startup and Shutdown with Unix Systems article.
    • This option is an alternative to the use of the --restart switch which will start the Agent from its Instance Start Script. If specified this option overrules the --restart switch.
  • --exec-stop
    • This option can be used should the Agent be stopped before installation. For example, when using systemd then the option --exec-stop="StopService" will stop the Agent service provided that the related systemd service has been created manually or by use of the --make-service switch. Alternatively users can specify individual commands, for example --exec-stop="sudo systemctl stop js7_agent_4445".
    • For systemd service files see the JS7 - systemd Service Files for automated Startup and Shutdown with Unix Systems article.
    • This option is an alternative to the use of the --restart switch which stops the Agent from its Instance Start Script. If specified this option overrules the --restart switch.
  • --return-values
    • Optionally specifies the path to a file to which return values will be added in the format <name>=<key>. For example:
      • log_file=install_js7_agent.centostest_primary.2022-03-20T04-54-31.log
      • backup_file=backup_js7_agent.centostest_primary.2.3.1.2022-03-20T04-54-31.tar.gz
    • An existing file will be overwritten. It is recommended to use a unique file name such as /tmp/return.$$.$RANDOM.properties.
    • A value from the file can be retrieved like this:
      • backup=$(cat /tmp/return.$$.$RANDOM.properties | grep "backup_file" | cut -d'=' -f2)
