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/
- ssl.conf
- subversion.conf
- trac.conf
- virtual_host.conf
- rewrite.conf
- mailman.conf
- trac.gdal.conf
- php.conf
- python.conf
- perl.conf
- phpldapadmin.conf - http auth and ssl directives for access to https://www.osgeo.org/ldapadmin
- working.conf - http auth and ssl directives for access to https://www.osgeo.org/_ldap/ldap.php
- webalizer.conf - http auth and ssl directives for access to https://www.osgeo.org/usage.php
Postfix
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

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
