Koji Hub Configuration

This is an exert from Paul Whalen's http://paulfedora.wordpress.com/2010/04/12/koji-hub-configuration/

It was agreed that all parts of our Koji build system would reside on Hong Kong. After successfully installing and configuring Postgresql the next step is the Koji Hub. In order for the Koji Hub to work Apache should be installed as well as a few additional modules. Run the following command as root:

yum install koji-hub httpd mod_ssl mod_python

Then edit the Apache conf file – ‘/etc/httpd/conf/httpd.conf’ and change the “MaxRequestsPerChild” to 100. On Hong Kong these setting were already in place as Apache was running and configured.

Next edit the ‘/etc/koji-hub/hub.conf’ file and add the following lines:

 DBName = koji
 DBUser = koji
 DBHost = localhost
 KojiDir = /mnt/koji
 LoginCreatesUser = On
 KojiWebURL = http://hongkong.proximity.on.ca/koji

Since we are using SSL for authentication, also add:

DNUsernameComponent = CN
ProxyDNs = "/C=CA/ST=Ontario/O=Seneca CDOT/OU=/CN=kojiweb/emailAddress="

And in the ‘/etc/httpd/conf.d/kojihub.conf’ uncomment the following lines:

<Location /kojihub>
SSLOptions +StdEnvVars

Using the Koji certificates, we need to add the following lines to ‘/etc/httpd/conf.d/ssl.conf’, under the section ‘VirtualHost _default_:443′:

SSLCertificateFile      /etc/pki/koji/certs/kojihub.crt
SSLCertificateKeyFile   /etc/pki/koji/certs/kojihub.key
SSLCertificateChainFile /etc/pki/koji/koji_ca_cert.crt
SSLCACertificateFile    /etc/pki/koji/koji_ca_cert.crt
SSLVerifyClient         require
SSLVerifyDepth          10

Even though SE Linux is not currently in use on Hong Kong, it may be in the future. In order to allow Apache to connect to the Postgresql database run the following command as root:

setsebool -P httpd_can_network_connect_db 1

To allow Koji to work, a skeleton filesystem needs to be created and the ownership changed so Apache can write to it as required. The following commands were executed:

mkdir -p /mnt/koji/{packages,repos,work,scratch}
chown -R apache.apache /mnt/koji

Then edited the '/etc/koji.conf' file and changed the following lines:

 ;url of XMLRPC server
server = http://hongkong.proximity.on.ca/kojihub
;url of web interface
weburl = http://hongkong.proximity.on.ca/koji
;url of package download site
pkgurl = http://hongkong.proximity.on.ca/packages
;path to the koji top directory
topdir = /mnt/koji
;configuration for SSL athentication
;client certificate
cert = ~/.koji/client.crt
;certificate of the CA that issued the client certificate
ca = ~/.koji/clientca.crt
;certificate of the CA that issued the HTTP server certificate
serverca = ~/.koji/serverca.crt

After this is competed, the final step is the addition of the user and builder accounts. First add the kojira account and grant repo privileges with the following command( this should be done before running kojira for the first time) :

su - kojiadmin
koji add-user kojira
koji grant-permission repo kojira

Then add as many builders as required using the following commands editing where required (this should also be done prior to running kojid on each host):

koji add-host arm-001-001 arm
koji add-host arm-001-002 arm
koji add-host arm-001-003 arm

Next… Koji Web.
