Bugzilla is Free/Libre and Open Source (FLOSS) bug tracker software developed by the Mozilla project. In this 20th article in the DevOps series, we will learn how to set up and configure Bugzilla.

Bugzilla is Web based and written using the Perl programming language. Released on August 26, 1998, it is used by a number of other FLOSS projects such as the Linux kernel, GNOME, Red Hat, Apache and KDE. It requires a database, Web server and at least Perl 5 to run. You can also configure it to use an SMTP mail server to send emails. It has been released under the Mozilla Public License.

Setup

A CentOS 7 (x86_64) guest virtual machine (VM) using KVM/QEMU will be used to install and configure Bugzilla. The host system is a Parabola GNU/Linux-libre x86_64 system, and Ansible is installed using the distribution package manager. The version of Ansible used is 2.6.0 as indicated below:

Advertisement
$ ansible --version

ansible 2.6.0

config file = /etc/ansible/ansible.cfg

configured module search path = [‘/home/guest/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’]

ansible python module location = /usr/lib/python3.6/site-packages/ansible

executable location = /usr/bin/ansible

python version = 3.6.5 (default, May 11 2018, 04:00:52) [GCC 8.1.0]

The Ansible inventory, playbook and configuration files are created on the host system as follows:

ansible/inventory/kvm/

/playbooks/configuration/

/files/

The inventory/kvm/inventory file contains the following:

bugzilla ansible_host=192.168.122.87 ansible_connection=ssh ansible_user=centos ansible_password=password

A ‘centos’ user is created in the guest VM, and sudo access is provided for this user using the visudo command. SELinux needs to allow access for port 80. You should also add an entry in the /etc/hosts file for the CentOS VM, as shown below:

192.168.122.87 bugzilla

You can now test connectivity from Ansible to the CentOS 7 VM using the following command:

$ ansible -i inventory/kvm/inventory bugzilla -m ping

sensu | SUCCESS => {

“changed”: false,

“ping”: “pong”

}

Repository

The installation of Bugzilla requires additional repositories — deltarpm and epel-release. These need to be installed first, and then ‘yum update’ is required to update the cache. The Ansible playbook for installing the repositories is given below:

---

- name: Repository setup

hosts: bugzilla

become: yes

become_method: sudo

gather_facts: yes

tags: [repo]

tasks:

- name: Install additional repositories

yum:

name: “{{ item }}”

state: present

with_items:

- “deltarpm”

- “epel-release”

- name: Yum update

yum: name=* update_cache=yes state=present

The above playbook can be invoked using the following command:

$ ansible-playbook -i inventory/kvm/inventory playbooks/configuration/bugzilla.yml --tags repo -vv -K

The ‘-vv’ represents the verbosity in the Ansible output. You can use up to four v’s for a more detailed output. The ‘-K’ option prompts for the sudo password for the ‘centos’ user account.

HTTPD

Bugzilla does require a Web server and the Apache HTTP (httpd) server package, and its dependencies need to be installed. The firewall needs to allow port 80. After installing the packages, the httpd service is started, and we wait for the server to listen on port 80. The Ansible playbook for the above tasks is as follows:

- name: Install httpd

hosts: bugzilla

become: yes

become_method: sudo

gather_facts: true

tags: [httpd]

tasks:

- name: Install httpd and dependency packages

yum:

name: “{{ item }}”

state: present

with_items:

- “httpd”

- “httpd-devel”

- “mod_ssl”

- “mod_perl”

- “mod_perl-devel”

- firewalld:

port: 80/tcp

state: enabled

- name: Start httpd

service:

name: httpd

state: started

- wait_for:

port: 80

The above playbook can be invoked using the following command:

$ ansible-playbook -i inventory/kvm/inventory playbooks/configuration/bugzilla.yml --tags httpd -vv -K

You can now open the following URL http://192.168.122.87 on your host system, and you should see the default httpd home page, as shown in Figure 1.

MariaDB

Bugzilla requires a database and we shall use MariaDB, the community-developed fork of the MySQL database. MariaDB and a few dependency packages need to be installed. The /etc/my.cnf configuration file needs to be updated with ‘max_allowed_packet=4M’ as required by Bugzilla. The database server is then started, and we wait for the server to listen on port 3306. A ‘bugs’ user account is created in MariaDB for use with Bugzilla along with a password. A ‘bugs’ database is also created. The Ansible playbook for setting up MariaDB is as follows:

- name: Install and configure MariaDB

hosts: bugzilla

become: yes

become_method: sudo

gather_facts: true

tags: [mariadb]

tasks:

- name: Install MariaDB and dependency packages

yum:

name: “{{ item }}”

state: present

with_items:

- “mariadb-server”

- “mariadb”

- “mariadb-devel”

- “MySQL-python”

- name: Allow maximum allowed packet

lineinfile:

path: /etc/my.cnf

line: ‘max_allowed_packet=4M’

- name: Start mariadb

service:

name: mariadb

state: started

- wait_for:

port: 3306

- name: Create bugs database user

mysql_user:

name: bugs

password: bugs123

priv: ‘*.*:ALL,GRANT’

state: present

- name: Create a database

mysql_db:

name: bugs

state: present

The above playbook can be invoked using the following command:

$ ansible-playbook -i inventory/kvm/inventory playbooks/configuration/bugzilla.yml --tags mariadb -vv -K

Bugzilla

Perl is required for Bugzilla, and we need to install the same and a few other Comprehensive Perl Archive Network (CPAN) dependencies. The Bugzilla-5.0 tarball is downloaded and copied to /var/www/html/bugzilla. The sources come with a checksetup.pl script that you can invoke to see if the minimum installation requirements are met. The first time you invoke the script, it will exit with errors stating that the Perl modules are missing. You can then use the install-module.pl script to install the Perl dependencies. You should then rerun the checksetup.pl script to check against the installed Perl modules. The /var/www/html/bugzilla/localconfig file needs to be updated with the database password. A bugzilla.conf for the Web server is created at /etc/httpd/conf.d/bugzilla, for which the file contents are shown below:

<VirtualHost *:80>

DocumentRoot /var/www/html/bugzilla/

</VirtualHost>

<Directory /var/www/html/bugzilla>

AddHandler cgi-script .cgi

Options +Indexes +ExecCGI

DirectoryIndex index.cgi

AllowOverride Limit FileInfo Indexes

</Directory>

The Ansible playbook to set up Bugzilla is as follows:

- name: Install and configure Bugzilla

hosts: bugzilla

become: yes

become_method: sudo

gather_facts: true

tags: [bugzilla]

tasks:

- name: Install Bugzilla dependency packages

yum:

name: “{{ item }}”

state: present

exclude: “perl-homedir”

with_items:

- “gcc”

- “gcc-c++”

- “graphviz”

- “graphviz-devel”

- “patchutils”

- “gd”

- “gd-devel”

- “wget”

- “perl*”

- “perl-CPAN”

- name: Download Bugzilla

unarchive:

src: https://ftp.mozilla.org/pub/mozilla.org/webtools/bugzilla-5.0.tar.gz

dest: /var/www/html

remote_src: yes

- name: Rename bugzilla-5.0 to bugzilla

command: mv /var/www/html/bugzilla-5.0 /var/www/html/bugzilla

- name: Install Perl modules

command: ./checksetup.pl

args:

chdir: /var/www/html/bugzilla

ignore_errors: true

- name: Install Perl modules

command: /usr/bin/perl install-module.pl --all

args:

chdir: /var/www/html/bugzilla

- name: Install Perl modules

command: ./checksetup.pl

args:

chdir: /var/www/html/bugzilla

ignore_errors: true

- name: Update localconfig

lineinfile:

path: /var/www/html/bugzilla/localconfig

regexp: ‘^$db_pass’

line: “$db_pass=’bugs123’;”

- name: Update htaccess

lineinfile:

path: /var/www/html/bugzilla/.htaccess

regexp: ‘^Options -’

line: “# Options - Indexes”

- name: Create /etc/httpd/conf.d/bugzilla.conf

copy:

src: ../../files/bugzilla.conf

dest: /etc/httpd/conf.d/bugzilla.conf

mode: 0644

The above playbook can be invoked using the following command:

$ ansible-playbook -i inventory/kvm/inventory playbooks/configuration/bugzilla.yml --tags bugzilla -vv -K

Final configuration

A final configuration step is to run checksetup.pl manually, as it prompts for user credentials. You can change to the /var/www/html/bugzilla directory, and execute the sudo ./checksetup.pl script, which will again check the installed Perl modules, create tables in the database, and prompt for the Administrator user account name and password. This has to be entered manually. A sample execution output is shown below for reference:

[centos@localhost bugzilla]$ sudo ./checksetup.pl

* Running on Linux 3.10.0-862.el7.x86_64 #1 SMP Fri Apr 20 16:44:24 UTC 2018
