Installing MON box for LCG 2.2.0 on RH 7.3

Note that by fluke the box I was installing when making these notes DID
have a host certificate. In principle, the R-GMA services don't need
certificates, and so you don't need a host certificate for your MON box;
however it looks like having a certificate avoids lots of confusing
warnings from the install scripts. There are plans to move to secure,
https, transfers for R-GMA, so you may well end up needing a certificate
anyway.
 
In short, a manual MON box install is easier if you do have a valid host 
certificate installed on the target machine.


Get guide from
http://grid-deployment.web.cern.ch/grid-deployment/gis/release-docs/LCG-2_2_0/RGMA/RGMA.html

I used guide v1.2 


Install a "standard" RedHat 7.3 box. Make sure you include GCC and CPP, 
(open)Jade and tetex/latex.
Avoid MySQL and Tomcat - will replace these.

Setup NTP client.


Get and run RGMA_manual_install_wget - this will give a load of RPMs.

Go to
	http://markusw.home.cern.ch/markusw/lcg2CAlist.html
get and upgrade the CAs.

Install the downloaded RPMs:
	Do MySQL and Tomcat RPMs by themselves first, then the rest.
	This stops their specific instructions scrolling past!
	Create MySQL root password, and check Tomcat config as requested.

	Make sure mysql is set to start automatically on reboot.

Now can install remaining RPMs.

Follow guide, section 5 on.
	After editing ld.so.conf, run  /sbin/ldconfig -v

	The environment variables and path just refer to the current shell 
	during the install process.

MON: dgc-grid-36.brunel.ac.uk
RGY: lcgic01.gridpp.rl.ac.uk

Can run config script without the q to see what's happening.
Must login as root for script to work - su not enough!

Run
	edg-java-security-tomcat-configure --insecure
	/opt/edg/sbin/edg-java-security-post-install.sh
Then
/opt/edg/etc/init.d/edg-tomcat4 start


Do crontab, as in guide.

/* Apparently, it's all done! */


Missing performance tweaks:
In /etc/tomcat4/tomcat4.conf add

	ulimit -n 16384
	# Java VM options for memory control
	JAVA_OPTS="-Xms64m -Xmx1024m"

In  /opt/edg/share/webapps/R-GMA/WEB-INF/web.xml
change maxTupleMemory for all servlets to 358.
(restart Tomcat)
