* '''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 database.communicate
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'''

* '''To make configuration Postgresql'''
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 edit /var/lib/pgsql/data/pg_hba.conf
<code># TYPE DATABASE USER CIDR-ADDRESS METHOD
host koji koji 127.0.0.1/32 trust
host koji apache 127.0.0.1/32 trust
host koji koji ::1/128 trust
host koji apache ::1/128 trust
local koji apache trust
local koji koji trust</code>
* '''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;

'''Last stage'''
'''Setup Koji Hub and Koji web'''
* Koji Hub Configuration
[http://fedoraproject.org/wiki/Koji/ServerHowTo#Koji_Hub Setting up 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 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

* Kojiweb configuration
[http://fedoraproject.org/wiki/Koji/ServerHowTo#Koji_Web_-_Interface_for_the_Masses setting up Koji web configuration]
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-web mod_ssl
2. Edit the file /etc/httpd/conf.d/kojiweb.conf:
PythonOption KojiHubURL http://hub.example.com/kojihub
PythonOption KojiWebURL http://www.example.com/koji
PythonOption KojiPackagesURL http://server.example.com/mnt/koji/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.
