DESCRIPTION:

== Overview ==

This script initializes an SDP instance on a single machine.

This script is intended to support two scenarios:

* First time SDP installation on a given machine.
* Adding new SDP instances (separate Helix Core data sets) to an existing
  SDP installation on a given machine.

And SDP instance is a single Helix Core data set, with its own unique
set of one set of users, changelist numbers, jobs, labels, versioned
files, etc. An organization may run a single instance or multiple
instances.

This is intended to be run either as root or as the operating system
user account (OSUSER) that p4d is configured to run as, typically
'perforce'.  It should be run as root for the initial install.
Subsequent additions of new instances do not require root.

== Directory Structure ==

If an initial install as done by a user other than root, various
directories must exist and be writable and owned by 'perforce' before starting:

* /p4
* /hxdepots
* /hxlogs
* /hxmetadata

The directories starting with '/hx' are configurable.

This script creates an init script in the /p4/N/bin directory.

== Crontab ==

Crontabs are generated for all server types except p4broker.

After running this script, set up the crontab based on templates
generated as /p4/common/etc/cron.d.  For convenience, a sample crontab
is generated for the current machine as /p4/p4.crontab.<SDPInstance> 
(or /p4/p4.crontab.<SDPInstance>.new if the former name exists).

These files should be copied or merged into any existing files named
with this convention:

/p4/common/etc/cron.d/crontab.<osuser>.<host>

where <osuser> is the user that services run as (typically 'perforce'),
and <host> is the short hostname (as returned by a 'hostname -s' command).

REQUIRED PARAMETERS:
 <instance>
	Specify the SDP instance name to add.  This is a reference to the Perforce
	Helix Core data set.

OPTIONS:
 -s <ServerID>
	Specify the ServerID, overriding the REPLICA_ID setting in the configuration
	file.

 -S <TargetServerID>
	Specify the ServerID of the P4TARGET of the server being installed.
	Use this only when setting up an HA replica of an edge server.

 -t <ServerType>
	Specify the server type, overriding the SERVER_TYPE setting in the config
	file.  Valid values are:
	* p4d_master - A master/commit server.
	* p4d_replica - A replica with all metadata from the master (not
	  filtered in any way).
	* p4d_filtered_replica - A filtered replica or filtered forwarding
	  replica.
	* p4d_edge - An edge server.
	* p4d_edge_replica - Replica of an edge server. If used,
	  '-S <TargetServerID>' is required.
	* p4broker - An SDP host running only a broker, with no p4d.
	* p4proxy - An SDP host running a proxy with no p4d.

 -tp <TargetPort>
	Specify the target port. Use only if ServerType is p4proxy and p4broker.

 -lp <ListenPort>
	Specify the listen port. Use only if ServerType is p4proxy and p4broker.

 -I [<svc>[,<svc2>]]
	Specify additional init scripts to be added to /p4/<instance>/bin
	for the instance.

	By default, the p4p service is installed only if '-t p4proxy' is
	specified, and p4dtg is never installed by default.  Valid values
	to specify are 'p4p' and 'dtg' (for the P4DTG init script).

	If services are not installed by default, they can be added later
	using templates in /p4/common/etc/init.d. Also, templates for
	systemd service files are supplied in /p4/common/etc/systemd/system.

 -MDD /bigdisk
 -MLG /jnl
 -MDB1 /db1
 -MDB2 /db2
	Specify the '-M*' to specify mount points, overriding DD/LG/DB1/DB2
	settings in the config file.  Sample:

	-MDD /bigdisk -MLG /jnl -MDB1 /fast

	If -MDB2 is not specified, it is set the the same value as -MDB1 if
	that is set, or else it defaults to the same default value as DB1.

 -f	Specify -f 'fast mode' to skip chown/chmod commands on depot files.
	This should only be used when you are certain the ownership and
	permissions are correct, and if you have large amounts of existing
	data for which the chown/chmod of the directory tree would be
	slow.

 -p	Specify '-p' to halt processing after preflight checks are complete,
	and before actual processing starts. By default, processing starts
	immediately upon successful completion of preflight checks.

 -L <log>
	Specify the path to a log file, or the special value 'off' to disable
	logging.  By default, all output (stdout and stderr) goes to this file
	in the current directory:

	mkdirs.<instance>.<datestamp>.log

	NOTE: This script is self-logging.  That is, output displayed on the
	screen is simultaneously captured in the log file.  Do not run this
	script with redirection operators like '> log' or '2>&1', and do not
	use 'tee'.

DEBUGGING OPTIONS:
 -test
 	Specify '-test' to execute a simulated install to /tmp/p4 as the install
	root (rather than /p4), and with the mount point directories specified in
	the configuration file prefixed with /tmp/hxmounts, defaulting to:
	* /tmp/hxmounts/hxdepots
	* /tmp/hxmounts/hxlogs
	* /tmp/hxmounts/hxmetadata
 
 -clean
	Specify '-clean' with '-test' to clean up from prior test installs,
	which will result in removal of files/folders installed under /tmp/hxmounts
	and /tmp/p4.

 	Do not specify '-clean' if you want to test a series of installs.

 -n	No-Op.  In No-Op mode, no actions that affect data or structures are
 	taken.  Instead, commands that would be run are displayed.  This is
	an alternative to -test. Unlike '-p' which stops after the preflight
	checks, with '-n' more processing logic can be exercised, with greater
	detail about what commands that would be executed without '-n'.

 -d     Increase verbosity for debugging.

 -D     Set extreme debugging verbosity, using bash '-x' mode. Also implies -d.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message

FILES:
	The mkdirs.sh script uses a configuration file for many settings.  A
	sample file, mkdirs.cfg, is included with the SDP.  After determining
	your SDP instance name (e.g. '1' or 'abc'), create a configuration
	file for it named mkdirs.<N>.cfg, replacing 'N' with your instance.

	Running 'mkdirs.sh N' will load configuration settings from mkdirs.N.cfg.

UPGRADING SDP:
	This script can be useful in testing and upgrading to new versions of
	the SDP, when the '-test' flag is used.

EXAMPLES:
	Example 1: Setup of first instance

	Setup of the first instance on a machine using the default instance name,
	'1', executed after using sudo to become root:
	$ sudo su -
	$ cd /hxdepots/sdp/Server/Unix/setup
	$ vi mkdirs.cfg

	# Adjust settings as desired, e.g P4PORT, P4BROKERPORT, etc.

	$ ./mkdirs.sh 1

	A log will be generated, mkdirs.1.<timestamp>.log

	Example 2: Setup of additional instance named 'abc'.

	Setup a second instance on the machine, which will be a separate Helix
	Core instance with its own P4ROOT, its own set of users and
	changelists, and its own license file (copied from the master instance).

	Note that while the first run of mkdirs.sh on a given machine should be
	done as root, but subsequent instance additions should be done as the
	'perforce' user (or whatever operating system user accounts Perforce
	Helix services run as).

	$ sudo su - perforce
	$ cd /hxdepots/sdp/Server/Unix/setup
	$ cp -p mkdirs.cfg mkdirs.abc.cfg
	$ vi mkdirs.abc.cfg

	# Adjust settings in mkdirs.abc.cfg as desired, e.g P4PORT, P4BROKERPORT, etc.

	$ ./mkdirs.sh abc

	A log will be generated, mkdirs.abc.<timestamp>.log

	Example 3: Setup of additional instance named 'alpha' to run a p4p:

	$ ./mkdirs.sh alpha -t p4proxy
