Description of current layout and installed software

Notes from Shawn on our PEER1 system:

• OS Version: Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
• For most elements of system i tried to stay with the default redhat locations and red hat el 4 rpms installed from peer 1's up2date repository. Reasoning, the servers are updated automatically against this repository and supported by PEER1 - reduce sysadmin load on keeping packages updated by using packages not available through PEER1 repository

Installed software using up2date

• apache - httpd-2.0.52-28.ent.i386
• postfix - postfix-2.2.10-1.RHEL4.2.i386
• php - php-4.3.9-3.22PIDH.i386
• python - python-2.3.4-14.3.i386
• mailman - mailman-2.1.5.1-34.rhel4.5.i386

Red Hat EL 4 rpms installed manually (rpm -i)

• MySQL-client-standard-5.0.27-0.rhel4.i386.rpm
• MySQL-server-standard-5.0.27-0.rhel4.i386.rpm
• MySQL-devel-standard-5.0.27-0.rhel4.i386.rpm
• MySQL-shared-compat-5.0.27-0.rhel4.i386.rpm
• clearsilver-0.10.1-1.2.el4.rf.i386.rpm
• sqlite-2.8.16-1.2.el4.rf.i386.rpm

Source Install

• drupal-4.7.4.tar.gz
• phpldapadmin-0.9.8.3.tar.gz
• trac-0.10.3.tar.gz

Apache

   /var/www/html/

Subversion

   /var/www/svn/repos/

Trac

  /var/www/trac/

IP tables custom

rules must be written here or won't exist when system updated

  /etc/sysconfig/iptables-custom/

System login and maintenance procedures

-- Note: if change root password must let PEER1 know the new password for backup/restore and tickets. i would prefer no root ssh login but, PEER1 needs root access.

Subversion maintanence

• subversion may lock if user ctl-c during checkout or checkout is interupted with an apache restart
• Need policy on who to contact and who can run 'svnadmin recover' as

priviledged access is needed (may need to stop/start apache to drop requests to repository before recover)

Backups (offsite, live, and otherwise)

• PEER1 is doing daily tape backup of entire system

Other backups

• MySQL being backed up every 2 hours with MySQL-zrm

* rsync backups, to /home/back then rsynced daily to other server (osgeo.net) /etc/ (daily) /var/www/html (daily) /var/lib/mailman (every 3 hours)

         /var/lib/msql-zrm (every 3 hours)

• subversion backups

-via svnadmin dump to /home/back/svn_dump/ (every 3 hours)

• trac backups

-via trac-admin hotcopy to /home/back/trac_copy/ (every 3 hours)

FDO Repository Merge

To merge repositories you need to parse through the dumpfiles.

In the fdo merge all subprojects had the same directory strucuture, /trunk/Providers/ All dumpfiles had to be 'filtered' to just pull the /trunk/Providers/* and drop branches and tags.

SVNDUMPFILTER

$ svndumpfilter include --help

Filter out nodes without given prefixes from dumpstream

Usage: svndumpfilter include PATH_PREFIX Options: --drop-empty-revs Remove revisions emptied by filtering --renumber-revs Renumbe revisions left after filtering --preserve-revprops Don't filter revision properties --quiet Do not display filtering statistics

$ svndumpfilter exclude --help Filter out nodes with given prefixes from dumpstream Usage: svndumpfilter exclude PATH_PREFIX Options: --drop-empty-revs Remove revisions emptied by filtering --renumber-revs Renumbe revisions left after filtering --preserve-revprops Don't filter revision properties --quiet Do not display filtering statistics

This process followed for all repositories

merge fdogdal trunk

 $ cat fdogdal.dmp | svndumpfilter include trunk/www/ > fdogdal-merge-trunk.www.dmp
 $ cat fdogdal.dmp | svndumpfilter include trunk/Providers/ > fdogdal-merge-trunk.Providers.GDAL.dmp

edit file and remove lines,

  Node-path: trunk/
  ....
  Node-action: add
  ....
  PROPS-END

  Node-path: trunk/www/
  ....
  Node-action: add
  ....
  PROPS-END

  Node-path: trunk/Providers/
  ....
  Node-action: add
  ....
  PROPS-END

Rename index.html to fdogdal-index.html

 $ perl -pi.bak -e 's/^Node-path:\ trunk\/www\/index.html/Node-path:\ trunk\/www\/fdogdal-index.html/g' fdo-merge.trunk.dmp

 $ svnadmin load /var/www/svn/repos/fdocore < fdogdal-merge.trunk.dmp
