Software Locations

  • SRB installation: /export/srb/srb
  • SRB Unix account: mcat
  • SRB Vault location: /export/vault1/vault
  • SRB Postgres backups: /export/vault1/backups
  • SRB zone: nara-umiacs
  • SRB Domain: umiacs


SRB Installation

Software

Download the following into /export/srb/srb:

Configuration

In the install.pl edit the following variables and set to the values below: 

$SRB_FILE="SRB3.3.1.tar"
$SRB_FILE_ALREADY_DECRYPTED=1;
$POSTGRES_FILE="postgresql-7.4.8.tar.gz";
$YOUR_ADMIN_PW="adminpw";
$YOUR_DOMAIN="umiacs";
$YOUR_ZONE="nara-umiacs";
$RESOURCE_NAME="narasrb01-unix";
$RESOURCE_DIR="/export/vault1/vault";
$SRB_PORT="7618";
$IP_ADDRESS_LOCALHOST="narasrb01.umiacs.umd.edu";
$SRB_CONFIGURE_OPTIONS="--enable-installdir=$SRB_INSTALL_DIR --enable-psgmcat 
      --enable-psghome=$postgresInstallDir --enable-commports";

around line 1053, change the host allow statement to use localhost

runCmdNoLog(0,"echo host all all 128.8.120.179 255.255.255.255 trust | cat >> $postgresData/pg_hba.conf");

Installation

Now, do the actual installation. This is a bit of a mess since we have to apply patches and from that I can tell, install.pl doesn't let you apply patches prior to doing the install. (All this done from /export/srb/srb) 

[mcat@naraapp01 srb]$ openssl enc -d -bf-cbc -in SRB3.3.1rele_bf.tar -out SRB3.3.1.tar
enter bf-cbc decryption password:
[mcat@naraapp01 srb]$ perl install.pl 
This script is install.pl version 3.x, last updated June 28, 2005
This host is narasrb01.umiacs.umd.edu
This host full network name is narasrb01.umiacs.umd.edu
This host full network address is narasrb01.umiacs.umd.edu
...
...
Some examples for testing and learning about the SRB are at:
http://www.sdsc.edu/srb/Edinburgh-Tutorials-May-2004/scmds.txt .
If your MCAT becomes slow, see index and vacuum options (top of script)
To use the SRB Scommands set your path to include the binaries:
set path=(/export/srb/srb/SRB3_3_1/utilities/bin $path)
Then Sinit, Sls, Sput, Sexit, etc should work.
To stop the the postgres and srb servers, run 'install.pl stop'
To restart the postgres and srb servers, run 'install.pl start'
To show the postgres and srb server processes, run 'install.pl ps'
For man pages (csh): alias Sman 'man -M /export/srb/srb/SRB3_3_1/utilities/man'
All done

Patching

Install the p1 patches, and uuid generation.

[mcat@naraapp01 srb]$ chmod 750 pg_backup.sh

PostGreSQL Tuning

Now, we have to tune postgres a little bit.

In /etc/sysctl.conf, add: 

#
# increase max shared memory to 256MB
kernel.shmmax=268435456
kernel.shmall=268435456

You can make it take affect immediately by running: 

[root@naraapp01 vault1]# echo 268435456 > /proc/sys/kernel/shmmax 
[root@naraapp01 vault1]# echo 268435456 > /proc/sys/kernel/shmall

In /etc/fstab, add 'noatime' to the mount for /export/srb. In /export/srb/srb/pgsql/data/psotgresql.conf change the shared buffers to:

shared_buffers = 28672


IPTables Config

In the UMfiles iptables config, create a new iptables-naraapp01 config and add the following lines after the allow for port 22 

######
# tcp
[0:0] -A tcp_packets -p tcp -m tcp --dport 22 -j tcpallowed
[0:0] -A tcp_packets -p tcp -m tcp --dport 7618 -j tcpallowed
[0:0] -A tcp_packets -p tcp -m tcp --dport 20000:20200 -j tcpallowed


Database Backups

Config

The postgresql databases are dumped and vacuumed nightly. The pg_backup.sh in /export/srb/srb is the script used to do this. It dumps backups to /export/vault1/backups. You can restore using the following command (substitute current backup where appropriate)

In pg_backup.sh, edit the following lines: 

#
# Postgresql username to perform backups under.
postgresql_username="mcat"

# Postgresql password for the Postgresql username (if required).
postgresql_password="password"

# Postgresql hostname to connect to.
postgresql_hostname="localhost"

##################
# Locations      #
##################
#
# Location to place backups.
location_backup_dir="/export/vault1/backups"

# Location to place the pg_backup.sh logfile.
location_logfile="/export/vault1/backups/dump.log"

# Location of the psql binaries.
location_binaries="/export/srb/srb/pgsql/bin"

##################
# Permissions    #
##################
#
# Permissions for the backup location.
permissions_backup_dir="0750"

# Permissions for the backup files.
permissions_backup_file="0640"
...
...
# You must comment out the line below before using this script
#echo "You must set all values in the configuration section in this file then run ./pg_backup.sh configtest before using this script" && exit 1

Restoring files

gunzip /export/vault1/backups/July-2005/2005-07-01/10:38-postgresql_database-MCAT-backup.gz
pg_restore -d database -F c /export/vault1/backups/July-2005/2005-07-01/10:38-postgresql_database-MCAT-backup

Upgrade to 3.4.1

Compile and install the new software. 

[mcat@naraapp01 srb]$ tar -xf ~/SRB3.4.1.tar 
[mcat@naraapp01 srb]$ mv SRBInstall SRBInstall.old
[mcat@naraapp01 SRB3_4_1]$ ./configure --enable-installdir=/export/srb/srb/SRBInstall --enable-psgmcat --enable-psghome=/export/srb/srb/pgsql --enable-commports --enable-commstart=20000 --enable-commnum=200 --enable-srbport=7618

[mcat@naraapp01 SRB3_4_1]$ make
[mcat@naraapp01 SRB3_4_1]$ make install

Upgrade the database to 3.4.0 on the way to 3.4.1. The psg upgrade file will fail on the modify's so you will manually need to run the alter table items. 

[mcat@naraapp01 SRB3_4_1]$ cd MCAT/data/
[mcat@naraapp01 data]$ /export/srb/srb/pgsql/bin/psql -d MCAT < 331to340patch.psg 
ERROR:  adding columns with defaults is not implemented
