== Project Description ==
The Fedora-ARM koji system uese HongKongIRAQ,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)

'''First stage'''
* '''Koji Authentication Selection'''
Setting Up a 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.Build System
The Kerberos credentials of the initial admin user will be necessary Koji components may live on separate resources as long as all resources are able to bootstrap the user databasecommunicate.To understand koji configuration is an important in project.
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'''KOJI Configuration'''

Bootstrapping the initial * Install 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.

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; So,Release 0.2-1 results here [http://ycshon.blogspot.com/2010/11/sbr-600-project-release-02-1.html in my blog] So,Release 0.3-1 results here [http://ycshon.blogspot.com/2010/11/sbr-600-project-release-02-1.html in my blog] '''Last stage''' '''Setup Koji Web and web''' * 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 [http://zenit.senecac.on.ca/wiki/index.php/Fedora_Arm_Secondary_Architecture/Koji_Certificates 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 LinuxIn 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 accountsThe final step is the addition of the user and builder accounts'''release 0.3-1'''
First add the kojira account and grant repo privileges with the following command( this should be done before running kojira for the first time) :'''1. kojiweb '''
su * Install Koji- kojiadminWeb koji add-user kojira* Required Configuration koji grant-permission repo kojira* Optional Configuration
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):'''2. Koji Builder'''
* Install kojid* Required Configuration* Optional Configuration (SSL certificates)* Add the host entry for the koji add-builder to the database* Add the host arm-001-001 armto the createrepo channel koji add-host arm-001-002 arm* A note on capacity koji add-host arm-001-003 arm* Start Kojid

1.Introduction
Koji-web is a set of scripts that run in mod_python and use the Cheetah templating engine to provide an web interface to Koji.
koji-web exposes a lot of information and also provides a means for certain operations, such as cancelling builds.
Run the following command as root:
root@localhost$ yum install koji'''release 0.3-web mod_ssl2'''
'''2. Edit the file /etc/httpd/conf.d/Test kojiweb.conf:'''
PythonOption KojiHubURL http://hub.example.com/kojihub* User account PythonOption KojiWebURL http://www.example.com/koji PythonOption KojiPackagesURL http://server.example.com/mnt/koji/* Build packages PythonOption WebCert /etc/pki/koji/kojiweb.pem PythonOption ClientCA /etc/pki/koji/koji_ca_cert.crt PythonOption KojiHubCA /etc/pki/koji/koji_ca_cert.crt PythonOption LoginTimeout 72 PythonOption Secret CHANGE_ME
3. Optional Configuration
/etc/httpd/conf.d/kojiweb.conf:
If using Kerberos, these settings need to be valid and inline with other services configurations.
<pre><Location /koji/login>
AuthType Kerberos
AuthName "Koji Web UI"
KrbMethodNegotiate on
KrbMethodK5Passwd off
KrbServiceName HTTP
KrbAuthRealm EXAMPLE.COM
Krb5Keytab /etc/httpd.keytab
KrbSaveCredentials off
Require valid-user
ErrorDocument 401 /koji-static/errors/unauthorized.html
</Location></pre>
/etc/httpd/conf.d/kojiweb.conf:
If using SSL auth, these settings need to be valid and inline with other services configurations.
<pre><Location /koji/login>
SSLOptions +StdEnvVars
</Location></pre>
/etc/httpd/conf.d/ssl.conf: Add the needed SSL options for apache.
<pre>SSLVerifyClient require
SSLVerifyDepth 10</pre>
If you are using SSL authentication, the "PythonOption WebCert" file above must contain both the public and private key.
Web interface now operational
At this point you should be able to point your web browser at the kojiweb URL and be presented with the koji interface. Many operations should work in read only mode at this point, and any configured users should be able to log in.

* 0.2 - '''Koji Database with PostgreSQL'''
To insert user permision to SQL server
To setup PostgreSQL for use with Koji
* 0.3 - '''Koji Web'''
To setup Koji web and Hub
