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

OpenLDAP

OpenLDAP Admin Guide

The ldap daemon can manipulated with, 

$ 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.

Loading an ldif file into an ldap directory 

  $ ldapadd -a -W -x -D "cn=Manager,dc=osgeo,dc=org" -f fileName.ldif

Accessing the ldap directory through phpldapadmin

access an ldapadmin interface at https://www.osgeo.org/ldapadmin

Access to this interface is restricted to the admin group

users can be added to the ou=people,dc=osgeo,dc=org once users are added they can then be added to cn=project,ou=svn,dc=osgeo,dc=org

login as cn=Manager,dc=osgeo,dc=org

  • expand dc=osgeo,dc=org tree
  • expand the ou=people tree
  • click on 'create new entry here'
  • choose 'custom' and then 'proceed'
    • RDN is in the form of uid=username
    • ObjectClass is InetOrgPerson
    • click proceed
      • cn is common name in form of firstname lastname
      • sn is surname - lastname
      • no optionals are required
    • click 'create object'
      • on this page click 'add new attribute'
        • choose mail
          • enter email address
          • click add
        • on this page click 'add new attribute'
          • choose userPassord
          • enter password as an md5
          • click add

this adds the new user to ou=people

to add users to the cn=project,ou=svn group

  • expand the ou=svn tree
  • click on cn=project
    • under member click 'add value'
    • add user to this in same form as you and howard are listed
    • or can click on the 'folder with magnifying glasss' to select a user

that's it.

LDAP Tools

Some public notes on OSGeo userids available at: 

 http://www.osgeo.org/osgeo_userid

Administrators can login to this special ldap search tool, and will see email address, and will have a link to edit the LDAP entries. You need to be in the cn=admin,ou=projects listing. 

 https://www.osgeo.org/cgi-bin/auth/ldap_web_search.py

SVN and other groups can be administered with the group editor. You need to either be in the group being viewed/modified or in the cn=admin,ou=projects group in order to edit a group.

Edit GDAL commit list: 

 https://www.osgeo.org/cgi-bin/auth/ldap_group.py?group=gdal

Edit Admins list: 

 https://www.osgeo.org/cgi-bin/auth/ldap_group.py?group=admin&ou=projects

To edit an individual userid use ldap_user_edit.py. If you add ?userid=osgeo_userid you can edit someone elses ldap entry as long as you are in the admins group.

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
