== Installing dCache 1.9.5 on machine with extended Quattor template ==

*This page describes the steps needed to get dCache up and running on a machine that was deployed with a quattor template that was extended for dCache

*The dCache 1.9.5 manual http://www.dcache.org/manuals/Book-1.9.5/
**The steps below follow basically what is described in the manual

*Start postgresql, Quattor will take care of this after reboot
<pre>
/etc/init.d/postgresql start
</pre>
*In /var/lib/pgsql/data/pg_hba.conf add
<pre>
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust
</pre>
*and restart
<pre>
/etc/init.d/postgresql restart
</pre>

*Create db and user
<pre>
createuser -U postgres --no-superuser --no-createrole --createdb --pwprompt srmdcache
createdb -U srmdcache dcache
</pre>
*Generate keys
<pre>
ssh-keygen -b 768 -t rsa1 -f /opt/d-cache//etc/server_key -N ""
ssh-keygen -b 1024 -t rsa1 -f /opt/d-cache//etc/host_key -N ""
</pre>

*Import pnfs database:
**go to jefke.wn and in /storage/userbackup/Maite_Db_backup/ find the last files and copy to the machine
<pre>
scp jefke.wn:/storage/userbackup/Maite_Db_backup/full_1334628123-pnfsdb.tar /var
scp jefke.wn:/storage/userbackup/Maite_Db_backup/full_1334628123.gz /var
</pre>
**Untar it in the correct location. ''Hint:'' tar -tf to see where the tree structure of the tarball.
**This configures contains the metadata for the pnfs database
<pre>
cd /opt
tar -xvf /var/full_1334628123-pnfsdb.tar
mv opt/pnfsdb/ .
rm -rf opt/
</pre>
**Populate the pnfs database
<pre>
su – postgres
zcat /var/full_1334628123.gz | psql postgres
</pre>

*A whole set of config files need to be adapted [[InstallDcache195ExtConfigFiles]]

*Run install script of dcache.
**Before you do this you have to remove /pnfs, it is put there by quattor to make all /store/user/username directories.
<pre>
rm -rf /pnfs/
</pre>
**Make sure pnfs is running
<pre>
/opt/pnfs/bin/pnfs start
</pre>
**Needed a little hack in the script to mount fs from localhost (really needed, I don't think so)
<pre>
/opt/d-cache/install/install.sh
</pre>
**with line 260 replace ''RET=${RET:-localhost}'' by ''RET="localhost"''

*The poolmanager.conf can be found here [[InstallDcache_PoolManagerConf]]

*In case the machine name is not anymore maite.iihe.ac.be some additional changes need to be performed:
**/pnfs/fs/admin/etc/config/serverName
**/pnfs/fs/admin/etc/config/dCache/dcache.conf
**vi "/pnfs/iihe/cms/store/user/odevroed/.(config)(dCache)/dcache.conf"
**more info in the dcache book in the section Global Configuration with Wormholes
**Run this
<pre>
touch /pnfs/fs/admin/etc/config/dCache/'.(fset)(dcache.conf)(io)(on)'
</pre>

*To be able to use the admin interface:
<pre>
cd /root/.ssh
scp ccq:/root/dCache_essential_config/keys/dcache_admin_key .
scp ccq:/root/dCache_essential_config/keys/dcache_admin_key.pub .
scp ccq:/root/dCache_essential_config/keys/dcache_admin_config .
cat ~/.ssh/dcache_admin_key.pub >> /opt/d-cache/config/authorized_keys
</pre>
**Go to the admin interface
<pre>
ssh -F /root/.ssh/dcache_admin_config admin@localhost
</pre>
