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
So,Release 0.2-1 results here in my blog
- 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
2. 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
3. Using SSL for authentication
Add this line.
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>
4.Using the Koji certificates
,and 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
5. SE Linux
In the IRAQ. 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
6.A skeleton filesystem
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://iraq.proximity.on.ca/kojihub ;url of web interface weburl = http://iraq.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
7. Build accounts 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
So,Release 0.2-2 results here in my blog
Last stage
Authorize Koji-web and Koji-hub resources: In this example, Koji-web and Koji-hub are running on localhost.
/var/lib/pgsql/data/pg_hba.conf: These settings need to be valid and inline with other services configurations.
Please note, the first matching auth line is used so this line must be above any other potential matches. Add:
host koji koji 127.0.0.1/32 trust local koji apache trust local koji koji trust
TO enable auth changes live:
root@localhost$ su - postgres postgres@localhost$ pg_ctl reload postgres@localhost$ exit
Bootstrapping the initial koji admin user into the PostgreSQL database: The initial admin user must be manually added to the user database using sql commands. Once they are added and given admin privilege, they may add additional users and change privileges of those users via the koji command line tool's administrative commands. However, if you choose to use the simple user/pass method of authentication, then any password setting/changing must be done manually via sql commands as there is no password manipulation support exposed through the koji tools.
The sql commands you need to use vary by authentication mechanism.
SSL Certificate authentication: there is no need for either a password or a Kerberos principal, so this will suffice:
koji=> insert into users (name, status, usertype) values ('admin-user-name', 0, 0);
Give yourself admin permissions
koji=> insert into user_perms (user_id, perm_id, creator_id) values (<id of user inserted above>, 1, <id of user inserted above>);
you can get the ID of the new user by running the query:
koji=> select * from users;
