Fedora-ARM,Dogfood - koji Hub

Project Name

Fedora-ARM Dogfood -Koji Hub

Project Description

The Fedora-ARM koji system uese HongKong,an x86_64 system, as the Koji hub.

The Fedora-ARM project to use ARM system as the Koji hub(this is called "Eating own dogfood" in the industry)

The project involves configuring the OpenRD-Client system as koji hub.

The Fedora ARM Koji system is running. It is currently building F13 under the supervision of Whalen and Chris Tyler. Koji have 22 hardware ARM builders. I am in the progress of building Fedora 13 under IRAQ.

Project Details

First stage

• Koji Authentication Selection

    Koji primarily supports Kerberos and SSL Certificate authentication. For basic koji command line access,     
    plain user/pass combinations are possible.  However, kojiweb does not support plain user/pass authentication.
    Furthermore, once either Kerberos or SSL Certificate authentication is enabled so that kojiweb will work,
    the plain user/pass method will stop working entirely. 
    As such plain user/pass authentication is a stop gap measure at best unless you intend to never setup
    a fully functional kojiweb instance.

    The Kerberos credentials of the initial admin user will be necessary to bootstrap the user database.

    For SSL authentication, SSL certificates for the xmlrpc server, for the various koji components,
    and one for the admin user will need to be setup

    1.Setting up SSL Certificates for authentication

    2.Setting up Kerberos for authentication

So,Release 0.1 results here in my blog

Second stage

• Koji Database

1.Create Database

yum install postgresql-server

2. Once installed you will then need to initialize the Database with the following command:

service postgresql initdb

3.Start the Postgresql service with:

service postgresql start

4. At this point the Postgresql server is installed and operational provided no errors were reported with the database initialized.

The next steps is to create a user named “koji”, set up Postgresql and populate the schema:

useradd koji
passwd -d koji
su - postgres
createuser koji
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles?(y/n) n

createdb -O koji koji
logout
su - koji
psql koji koji < /usr/share/doc/koji*/docs/schema.sql
exit

• Koji Hub Configuration

1. introduction

It was agreed that all parts of our Koji build system would reside on IRAQ.

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 IRAQ 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://iraq.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

</Location>

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 IRAQ,

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://iraqong.proximity.on.ca/koji

;url of package download site

pkgurl = http://iraq.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

== Project Plan ==

Goals for each release:

* 0.1 - Koji Certificates

Koji Hub setup - Certificates/security

* 0.2 - Koji Hub setup and Koji Database

Koji Hub Setup- Configuration

To setup PostgreSQL for use with Koji

* 0.3 - Koji Web

Build software with koji hub
