Background
SLAC install has some differences
- all files kept in AFS
- centralised configuration
- mount of disk partition for data
- move of mysql database storage to separate partition
- use of apache redirect for calls
AFS
- symlinked
/opt/perfsonar
to/afs/slac.stanford.edu/package/perfSONAR-PS/dist/
- config files kept in
/afs/slac.stanford.edu/package/perfSONAR-PS/etc/
- each file is named to appropriate service
- customisations on init.d files to reflect above
- install file located at
/afs/slac.stanford.edu/package/perfSONAR-PS/etc/init.d/
- will delete services from install and put in new ones with pointers to new config files
- add's chkconfig stuff
- install file located at
Partitions
- largest disk partition mounted at
/var/lib/perfsonar
for data - mysql
mv /var/lib/mysql /var/lib/perfsonar/
sudo ln -sf /var/lib/perfsonar/mysql/ mysql

To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h psnr-bw01 password 'new-password' Alternatively you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script!
