$ sudo /sbin/service ldap start|stop|restart|
 
 
 
The main ldap config file is,
 
/etc/openldap/slapd.conf
 
 
 
Currently ldap structure is pretty basic.  The purpose for keeping this structure simple is to allow for a more complex structure to be evolved as ldap becomes increasingly integrated into the full osgeo systems structure.

backup-svn_full.sh runs once a day at 1 am and does a 'svnadmin hotcopy' of the repository in /home/back/svn_backup/project/full.  14 copies of the repository are kept. 
 
 
 
When adding a new svn repository, make sure to edit both the _full and _incremental scripts to add backups for your projects.  You will also have to create the /home/back/svn_backup/project/{full,incremental} directories or the scripts will not work. 
 
'''rsync_back''' rsyncs www.osgeo.org/home/back with test.osgeo.net/home/back (the second PEER1 server)

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.

Apache

As the system is Red Hat use /sbin/services httpd start|stop|restart|configtest|reload instead of /usr/sbin/apchectl

the main Config file for apache is, /etc/httpd/conf/httpd.conf

additional config files are at /etc/httpd/conf.d/

Postfix

Postfix documentation

The postfix daemon can be be stared|stopped|restarted|reloaded with,

$ sudo /sbin/service postfix start|stop|restart|reload|abort|flush|check|status|condrestart

The main postfix config file is,

/etc/postfix/main.cfg

The aliases file is,

/etc/aliases

If aliases file is edited remember to run newaliases

 $ sudo /usr/bin/newaliases
 $ sudo /sbin/service postfix reload

LDAP

See SAC:LDAP

Subversion

See Subversion for details on subversion configuration.

Trac

Trac Instances

Mailman Maintenance

See SAC:Mailing Lists.

Backups

See SAC:Backups.

DNS

See SAC DNS Registry.

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
