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
  • python-clearsilver-0.10.1-1.2.el4.rf.i386.rpm
  • python-sqlite-1.0.1-12.el4.rf.i386.rpm
  • subversion-1.4.3-0.1.el4.rf.i386.rpm
  • mod_dav_svn-1.4.3-0.1.el4.rf.i386.rpm

Not specific to Red Hat EL 4 rpms installed manually

  • MySQL-zrm-1.1.2-1.noarch.rpm

Source Install

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

Paths to services directories

Apache root directory 

   /var/www/html/

Subversion parent directory 

   /var/www/svn/repos/

Trac parent directory 

  /var/www/trac/

IP tables custom

All iptables rules must be written in /etc/sysconfig/iptables-custom

Current custom rules are:

/etc/sysconfig/iptables-custom/SSH 

  *filter
  -A OUTPUT -p tcp --dport 22 -j ACCEPT
  COMMIT

/etc/sysconfig/iptables-custom/VERITAS

note: this file was placed here by PEER1 

  *filter
  -A INPUT -s 10.0.48.0/24 -d 0/0 -p tcp -j ACCEPT
  -A OUTPUT -s 0/0 -d 10.0.48.0/24 -p tcp -j ACCEPT
  COMMIT

System login and maintenance procedures

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

Subversion maintanence

Subversion Book

Creating a repository

  $ sudo mkdir /var/www/svn/repos/<repo_name>
  $ sudo svnadmin /var/www/svn/repos/<repo_name>
  $ sudo chown -R apache:apache /var/www/svn/repos/<repo_name>

Loading a repository from a dumpfile

  $ sudo svnadmin load /var/www/svn/repos/<repo_name> < /path/to/dumpfile
  $ sudo chown -R apache:apache /var/www/svn/repos/<repo_name>

Dumping a repository

  $ sudo svnadmin dump /var/www/svn/repos/<repo_name> > dumpfile

Recovering / unlocking repository

  • 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)

Subversion was upgraded to version 1.4.3 (30 Jan. 2007) to reduce the repository locking problem if ctl-c used to end a checkout.

If the repository locks the following command should be used to recover the repository: 

  $ sudo svnadmin --wait recover /var/www/svn/repos/<repo_name>
  $ sudo chown -R apache:apache /var/www/svn/repos/<repo_name>

In most cases this will work in the odd case that you are waiting a very long time for the command to run then apache may have to be restarted to drop anything accessing the repository and preventing the repository from being recovered 

  $ sudo /sbin/service httpd restart
  $ sudo svnadmin --wait recover /var/www/svn/repos/<repo_name>
  $ sudo chown -R apache:apache /var/www/svn/repos/<repo_name>

TRAC Maintenance

Trac Guide

Creating a trac instance

  $ sudo trac-admin /var/www/trac/<proj_name> initenv
  $ sudo chown -R apache:apache /var/www/trac/<proj_name>

Hotcopy a trac instance

  $ sudo trac-admin /var/www/html/trac/<proj_name> hotcopy /path/to/copy/trac/to

Mailman Maintenance

create a new mailing list

  $sudo /usr/lib/mailman/bin/newlist listname admins@email lists_passwd

renaming a list

  • create new list
  $sudo /usr/lib/mailman/bin/newlist listname admins@email lists_passwd
  • move original lists archive to newlists archive location
  $ sudo cp /var/lib/mailman/oldlist/oldlist.mbox/oldlist.mbox \
    /var/lib/mailman/newlist/newlist.mbox/
  • create archive
  $ sudo /usr/lib/mailman/bin/arch --wipe newlist
  • export subscribers from old list regular and digest members
  $ sudo /usr/lib/mailman/bin/list_members -r listname > listname-regular.txt
  $ sudo /usr/lib/mailman/bin/list_members -d listname > listname-digest.txt
  • import subscribers into new list
  $ sudo /usr/lib/mailman/bin/add_members --regular-members=listname-regular.txt --welcome-msg=y listname
  $ sudo /usr/lib/mailman/bin/add_members --digest-members=listname-digest.txt --welcome-msg=y listname
  • remove old list
  $ sudo /usr/lib/mailman/bin/rmlist listname
  • update aliases and check that proper permissions are set
  $ sudo /usr/lib/mailman/bin/genaliases
  $ sudo /usr/lib/mailman/bin/check_perms -f

Backups

Daily tape backup

  • PEER1 is doing daily tape backup of entire system

Other backups

Mysql

MySQL is being backed up using MySQL-zrm

current cron jobs for backups

/etc/cron.d/backup.cron 

  #### Backup cron jobs 
  # min hour day month dayofweek user command
  #
  # Daily rsync to /home/back
  # /etc
  05 10 * * * root /usr/bin/rsync -a --delete /etc/ /home/back/etc/
  # /var/www/html

  # once a day rsync /home/back to osgeo2.osgeo.net
  0 22 * * * root /root/scripts/rsync_back.pl

backup script are in /root/scripts

backup_trac_svn.sh calls separate scripts to backup trac and svn repositories and place tgz files of the backups in /home/back/svn_backup and /home/back/trac_backup which are held for 14 days. rsync_back rsyncs www.osgeo.org/home/back with test.osgeo.net/home/back (the second PEER1 server)

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

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