glideinWMS ini file based installer

Description

MAJOR DISCLAIMER: This method of installation has NOT been officially released as yet. While it has been tested with V2.4+, keep that in mind

This installer uses a configuration file (ini format) to perform the installation of the glideinWMS services in lieu of a question/answer (q/a) type installer. It requires knowledge and planning of the glideinWMS services just as the the q/a installer did. The major difference is that you essentially pre-answer all the questions previously asked and document them in the ini file. In addition to having them documented, this performs the actual installation faster and allows for re-installs more quickly when some of the attribute values are incorrect (an inevitable consequence of a complex set of services such as these).

Another major difference, with this installer, is that it does NOT modify any scripts that set a user environment upon log in, e.g., .bashrc file, /etc/profile.d files, et al. Instead, an environment script is created for each service in its respective "home" location. If inclusion of these scripts is required at a location, it will need to be performed manually. The only exception to this is when privilege separation is in effect, in which case, the /etc/condor/privsep_config file is created. This location is hard-coded in Condor and cannot be changed.

Service Script Example
wmscollector
usercollector
submit 		condor_location/condor.sh  
factory install_location/factory.sh  
vofrontend install_location/frontend.sh

Access via CVS

To access the branch for the ini-based installer: 
export CVSROOT=cvsuser@cdcvs.fnal.gov:/cvs/cd
cvs -d :pserver:anonymous@cdcvs.fnal.gov:/cvs/cd_read_only co -r branch_v2plus  glideinWMS

the installation process - general comments

There are several general comments about the installation process that are probably good to understand before getting started.

NOTE: There is no upgrade process available from V1.6 to a V2+ version of glideinWMS. You must install from V2+ from scratch.

Installation sequence

There are some dependencies between the various services. So the order of installation is critical. They must be installed in this order:
  1. WMS Collector
  2. Factory
  3. User Collector
  4. Schedd/submit
  5. VOFrontend

IMPORTANT - This dependency between services also dictates that if you get an error during the installation that requires a change to the ini file. You should go back and re-install ALL services.

OSG/VDT client software

The vdt_location attribute identifies where the OSG/VDT client software is installed. If the OSG/VDT client software is used for a node, the installer verifies its existence based on the presence of 2 files:
  1. The *vdt_location*/setup.sh script
  2. The existence of a voms-proxy-init executable in the installation. This also implies that grid-proxy-init is also available.
If they already exist, the installer will not attempt to reinstall that software.

Pacman is used to install the OSG/VDT client software and the CA certificates if they are not already installed

manage-glideins script

The script used to perform the installations is glideinWMS/install/manage-glideins .

Usage: ./manage-glideins -- --ini <--debug>

action: install, start, stop, status
services: wmscollector usercollector factory submit vofrontend
all - can only be used with start/stop/status actions
--debug: When used with start/stop/status actions, it will
display the series of commands used.

This process can be used to install, start, stop or check the status of
the glidein services based on the configuration in the specified ini file.

The start/stop/status actions can be performed remotely providing the user
has valid access to the other service's node via the .k5login of that user.
For these actions, this process ssh's into the services node thereby insuring
a clean environment.

The install/install-node/create-entries can only be used on the node for that
service.

./manage-glideins --install-node --ini

This option allows you to install all services for the node you are installing
on. There are some limitation to this.

./manage-glideins --create-entries --ini

This option can be used to select new glidein entry points after the
initial installation of a factory service. If will walk you through the same
question and answer process querying ReSS and BDII for resources. It will then
create a file containing the entry elements for those selected. This can then
be merged with the existing Factory configuration file.

  • cd glideinWMS/install
  • ./manage-glideins --install service_name --ini inifile_location

The script can also be used to "remotely" start and stop glidein services. However, this assumes you have remote access (via ssh) to the other node/account.

glideinWMS ini file

All ini file attributes are required. However, in several cases the value may be left empty. These should be noted in the comments column of the tables.

Default section

The attributes in this section apply to all subsequent sections in the ini file unless they are overridden specifically in that section.

The 2 pacman related attributes are used to bring down the OSG/VDT client software and CA certificates if they are not already installed on the node. These should not be changed.

attribute Example Description Comments
pacman_version pacman-3.28 Version of pacman to use.  
pacman_url http://physics.bu.edu/pacman/sample_cache/tarballs URL to retrieve pacman.

PARAG:
MAKE THIS THE URL TO THE TARBALL SO WE CAN GET RID OF pacman_version IF IT IS STILL REQUIRED. 		 

WMSCollector section

attribute Example Description Comments
node / hostname cms-xen21.fnal.gov hostname for WMS Collector. The WMS collector and Factory must be collocated at this time.
unix_acct / username condor (or whatever non-root user you decide on) UNIX user account that this services will run under. DO NOT use "root". Since this is a condor installation, for security purpose this should be installed as root user (although it is not required).

However, if privilege separation is being used, you MUST install as root user as the condor switchboard requires it.
service_name condor-wms Used in naming the condor startup script (condor_).
Example - condor-wms 		This allows multiple glidein condor services to be used in init.d services with unique names.

This is also used in the condor_mapfile of the other glidein services as the 'nickname' to more easily identify the DNs in that file.
condor_location /home/weigand/glidein/condor-wms Directory in which the condor software will be installed.  
collector_port 9618 (condor default) Defines the Condor Collector port. Condor default is 9618. If multiple glidein services are installed on the same node, this should be unique of each service.

* y - privilege separation is used
* n - privilege separation is not used 		SHOULD BE A LINK IN HERE EXPLAINING THIS
frontend_users cms_jgw : vo_cms A comma separated list mapping the vofrontend's service name to the UNIX account that has been created for it.

The format for each frontend is:
service_name : unix account 		Only used if privilege separation is used.

The UNIX account for each frontend MUST be created in advance.

The service name MUST be the value for the VOFrontend section's service_name attribute.
certificates/x509_cert_dir /home/weigand/glidein/vdt The parent directory where the CA certificates are maintained.

PARAG:
THIS SHOULD NOT BE PARENT DIR BUT DIRECTLY POINT TO THE CERTIFICATE DIR

x509_key = /etc/grid-security/cmssrv97condorkey.pem
; x509_proxy = /tmp/user_proxy
If a certificate, all that is need needed is the cert file name, not the key.pem file (full path required)
eg. hostcert.pem
gsi_dn /DC=org/DC=doegrids/OU=Services/CN=glidein/cms-xen21.fnal.gov If the gsi_authentication is:
* cert, the subject of the certificate
* proxy, the issuer of the proxy 		openssl x509 -issuer -subject -noout -in [cert_proxy_location]

This is used to populate the condor_config file GSI_DAEMON_NAME and condor_mapfile entries of this and the other glidein services.
condor_tarball /home/weigand/tarballs/condor-7.5.0-linux-x86-rhel3-dynamic.tar.gz Location of the condor tarball. It must be a zipped tarball. The installation script will perform the installation of condor.

vdt_location /home/weigand/glidein/vdt The location of the OSG/VDT client software. The installer looks for the existence of 2 files to verify it this is an OSG/VDT client installation:
1. setup.sh
2. existence of a voms-proxy-init executable.
pacman_location /home/weigand/glidein Parent directory for the pacman software.

PARAG:
CLARIFY IN DOCS THAT THIS WILL CREATE a pacman-xxx in this directory 		The installer looks for the existence of 2 files to verify it this is an OSG/VDT client installation:
1. setup.sh
2. existence of a voms-proxy-init executable.
Pacman is used to install the OSG/VDT client software and the CA certificates if they are not already installed
glidein_install_dir / glideinwms_location /home/weigand/glideinWMS Directory of the glideinWMS software. Since this is a Condor service only, this software is only used during the installation process.

Factory section

attribute Example Description Comments

install_location /home/weigand/glidein/factory HOME directory for the factory software.  
client_files / client_log_dir + client_proxy_dir /var/spool/factory-jgw This identifies the location of the client log and proxy files.

PARAG
; Validation: client_files
; Dir exists and/or we can create and write to it.
; Contains subdirs for clientlogs and clientproxies
; General comment: It's confusing when you name the variable as client_files.
; Prefer name change but don't have good name right now.
If privilege separation is used, then the entire path (inclusive of this directory) must be root-writable-only (0755 and owned by root).

If privilege separation is not used, then the directory will be created by the install script assuming the factory user has write permissions to the parent directory.
instance_name v2_2 Used in naming files and directories.  
gsi_authentication cert Used to identify the Factory to the other glidein services.
Valid values:
* cert - certificate used
* proxy - proxy used 		Valid values: cert proxy

* y - uses CCB
* n - does not use CCB 		 
gcb_list ????? PARAG:

WE MAYBE ABLE TO GET RID OF IT 		OBSOLETE????

* osg-ress-4.fnal.gov - OSG ITB
bdii_host exp-bdii.cern.ch Identifies the ReSS server to be used to select Entry points (CEs) to submit glidein pilot jobs to.
The only validation performed is to verify if that server exists. 		exp-bdii.cern.ch is the only one I am aware of.
