CentOS setup for Subversion Edge

http://www.hitechsavvy.com/?p=292#more-292 is really useful!

To get network going edit ifcfg-eth0 in /etc/sysconfig/network-scripts/

Need to use vi for this - minimal install doesn't have anything else.

ifcfg-eth0

DEVICE="eth0"
NM_CONTROLLED=no
ONBOOT=yes
HWADDR=6E:89:F7:F2:8B:47
TYPE=Ethernet
BOOTPROTO=none
IPADDR=130.209.45.49
NETMASK=255.255.255.0
GATEWAY=130.209.45.1
DNS1=130.209.4.16
DNS2=130.209.4.18
DNS3=130.209.16.6
DOMAIN=physics.gla.ac.uk
IPV6INIT=no
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03

The UUID here was put in by the GUI network setup, as was some of the other stuff. The Minimum required is IPADDR, BOOTPROTO (maybe?), NETMASK, GATEWAY, DNS1(2,3,etc).

To edit file with vi:

vi filename
i (insert mode)
ESC (command mode)
:x (Exit, saving changes)
:q! (Exit and ignore any changes)

vi cheat sheet at http://www.lagmonster.org/docs/vi.html

Enable network with service network start

Edit /etc/yum/conf to include the line

proxy=http://wwwcache.gla.ac.uk:8080/

then yum update to update system. Then use yum install packagename to install other stuff, like nano, ntp etc.

Install sudo. seems to want it.

Install system-config-firewall-tui using yum and run it.

yum install java-1.6.0-openjdk

Set environment variable by creating a file in /etc/profile.d/

java.sh

export JAVA_HOME=/usr/lib/jvm/jre

(if the install worked properly /usr/lib/jvm/jre should be a symlink to /etc/alternatives/jre which in turn should link to the actual jre, e.g. /usr/lib/jvm-exports/jre-1.6.0-openjdk.x86_64)

Python should be installed. Apparently need to install python-ldap though.

Create user with:

useradd username -p password

Create directory, e.g.

mkdir /export0/subversion_edge
chown subversion:subversion /export0/subversion_edge/

Put the downloaded file in subversion user's directory, switch to the user and extract the file

tar -zxvf CollabNetSubversionEdge-3.1.0_linux-x86_64.tar

change back to root (su -) and:

[root@unst ~]# /export0/subversion_edge/csvn/bin/csvn install
Detected RHEL or Fedora:
 Installing the CSVN Console daemon..
Setting RUN_AS_USER to: 'root'. Please edit '../data/conf/csvn.conf' if this needs to be adjusted
Setting JAVA_HOME to: '/usr/lib/jvm/jre'. Please edit '../data/conf/csvn.conf' if this needs to be adjusted.

Edit the csvn.conf file to change the RUN_AS_USER. Can also set the proxy here.

Change back to the subversion user and start the system

/export0/subversion_edge/csvn/bin/csvn start

After a minute or so should be able to access the console at http://servername:3343/csvn or https://servername:4434/csvn/

For troubleshooting this gives you the startup messages:

csvn console

To allow the non-privileged user to bind to ports < 1024 there are some tweaks required. Either:

1. Give root ownership of the httpd_bind utility to allow it to start the server from init.d, or
2. edit sudoers to give allow subversion user to start apache

When you set a port < 1024 in the web interface for the svn server it will complain and show the commands required to make it work, for both options. I chose the httpd_bind route.

 chown root:subversion /export0/subversion_edge/csvn/lib/httpd_bind/httpd_bind
 chmod u+s /export0/subversion_edge/csvn/lib/httpd_bind/httpd_bind

To start the console and the svn/httpd services on boot:

csvn/bin/csvn install
csvn/bin/csvn-httpd install
