3.2. Linux

Some Linux distributions include Bugzilla and its dependencies in their package management systems. If you have root access, installing Bugzilla on any Linux system could be as simple as finding the Bugzilla package in the package management application and installing it. There may be a small bit of additional configuration required.

If you are installing your machine from scratch, Quick Start (Ubuntu Linux 22.04) may be the best instructions for you.

3.2.1. Install Packages

Use your distribution’s package manager to install Perl, your preferred database engine (MySQL or MariaDB if in doubt), and a webserver (Apache if in doubt). Some distributions even have a Bugzilla package, although that will vary in age.

The commands below will install those things and some of Bugzilla’s other prerequisites as well. If you find a package doesn’t install or the name is not found, just remove it from the list and reissue the command. If you want to use a different database or webserver, substitute the package names as appropriate. Fedora, CentOS Stream and RHEL

The following command will install Fedora’s packaged version of Bugzilla:

dnf install bugzilla httpd mariadb-server

Then, you can skip to configuring your database. It may be useful to know that Fedora stores the Bugzilla files in /usr/share/bugzilla, so that’s where you’ll run checksetup.pl.

If you want to install a version of Bugzilla from the Bugzilla project or have it on RHEL or CentOS, you will need to do the following instead:

On CentOS Stream and RHEl, add the Fedora EPEL repo, in the way described in the installation instructions.

Run the following to install the base Bugzilla dependencies:

dnf install git httpd httpd-devel mariadb-devel gcc mariadb-server mod_perl mod_perl-devel 'perl(autodie)' 'perl(CGI)' 'perl(Date::Format)' 'perl(DateTime)' 'perl(DateTime::TimeZone)' 'perl(DBI)' 'perl(DBD::mysql)' 'perl(DBIx::Connector)' 'perl(Digest::SHA)' 'perl(Email::MIME)' 'perl(Email::Sender)' 'perl(fields)' 'perl(JSON::XS)' 'perl(List::MoreUtils)' 'perl(Math::Random::ISAAC)' 'perl(Memoize)' 'perl(Safe)' 'perl(Template)' 'perl(URI)'

On Fedora, all the optional dependencies are available:

dnf install gd-devel graphviz patchutils 'perl(Apache2::SizeLimit)' 'perl(Authen::Radius)' 'perl(Authen::SASL)' 'perl(Cache::Memcached)' 'perl(Chart::Lines)' 'perl(Daemon::Generic)' 'perl(Email::Reply)' 'perl(Encode)' 'perl(Encode::Detect)' 'perl(File::Copy::Recursive)' 'perl(File::MimeInfo::Magic)' 'perl(File::Which)' 'perl(GD)' 'perl(GD::Graph)' 'perl(GD::Text)' 'perl(HTML::FormatText::WithLinks)' 'perl(HTML::Parser)' 'perl(HTML::Scrubber)' 'perl(IO::Scalar)' 'perl(JSON::RPC)' 'perl(LWP::UserAgent)' 'perl(MIME::Parser)' 'perl(mod_perl2)' 'perl(Net::LDAP)' 'perl(Net::SMTP::SSL)' 'perl(PatchReader)' 'perl(SOAP::Lite)' 'perl(Template::Plugin::GD::Image)' 'perl(Test::Taint)' 'perl(TheSchwartz)' 'perl(XMLRPC::Lite)' 'perl(XML::Twig)'

On CentOS Stream and RHEL with EPEL, some modules are missing in the repositories, so use the following instead:

dnf install gd-devel graphviz patchutils 'perl(Apache2::SizeLimit)' 'perl(Authen::Radius)' 'perl(Authen::SASL)' 'perl(Cache::Memcached)' 'perl(Encode)' 'perl(Encode::Detect)' 'perl(File::Copy::Recursive)' 'perl(File::MimeInfo::Magic)' 'perl(File::Which)' 'perl(GD)' 'perl(GD::Graph)' 'perl(GD::Text)' 'perl(HTML::Parser)' 'perl(HTML::Scrubber)' 'perl(IO::Scalar)' 'perl(JSON::RPC)' 'perl(LWP::UserAgent)' 'perl(MIME::Parser)' 'perl(mod_perl2)' 'perl(Net::LDAP)' 'perl(Net::SMTP::SSL)' 'perl(SOAP::Lite)' 'perl(Test::Taint)' 'perl(XMLRPC::Lite)' 'perl(XML::Twig)'

and install the missing optional modules with:

cd /var/www/html/bugzilla/ && ./install-module.pl Chart::Lines Daemon::Generic Email::Reply HTML::FormatText::WithLinks PatchReader Template::Plugin::GD::Image TheSchwartz

If you plan to use a database other than MariaDB, you will need to also install the appropriate packages for that. Ubuntu and Debian

You can install required packages with: apt install apache2 build-essential git libcgi-pm-perl libdatetime-perl libdatetime-timezone-perl libdbi-perl libdbix-connector-perl libdigest-sha-perl libemail-address-perl libemail-mime-perl libemail-sender-perl libjson-xs-perl liblist-moreutils-perl libmath-random-isaac-perl libtemplate-perl libtimedate-perl liburi-perl libmariadb-dev-compat libdbd-mysql-perl mariadb-server

If you plan to use a database other than MariaDB, you will need to also install the appropriate packages for that (in the command above, the packages required for MariaDB are libdbd-mysql-perl, libmariadb-dev-compat and mariadb-server).

You can install optional packages with: apt install graphviz libapache2-mod-perl2 libapache2-mod-perl2-dev libauthen-radius-perl libauthen-sasl-perl libcache-memcached-perl libchart-perl libdaemon-generic-perl libemail-reply-perl libencode-detect-perl libencode-perl libfile-copy-recursive-perl libfile-mimeinfo-perl libfile-which-perl libgd-dev libgd-graph-perl libgd-perl libgd-text-perl libhtml-formattext-withlinks-perl libhtml-parser-perl libhtml-scrubber-perl libio-stringy-perl libjson-rpc-perl libmime-tools-perl libnet-ldap-perl libnet-smtp-ssl-perl libsoap-lite-perl libtemplate-plugin-gd-perl libtest-taint-perl libtheschwartz-perl libwww-perl libxmlrpc-lite-perl libxml-twig-perl

There is no Ubuntu package for PatchReader and so you will have to install that module outside the package manager if you want it. Gentoo

emerge -av bugzilla

will install Bugzilla and all its dependencies. If you don’t have the vhosts USE flag enabled, Bugzilla will end up in /var/www/localhost/bugzilla.

Then, you can skip to configuring your database. openSUSE

zypper in bugzilla

has been available in the openSUSE Leap repositories since 15.2 and is in the openSUSE Tumbleweed repositories, also comes with an optional bugzilla-apache package, that allows you to skip to configuring your database

3.2.2. Perl

Test which version of Perl you have installed with:

$ perl -v

Bugzilla requires at least Perl 5.14.0.

3.2.3. Bugzilla

The best way to get Bugzilla is to check it out from git:

git clone --branch release-X.X-stable https://github.com/bugzilla/bugzilla

Run the above command in your home directory, replacing “X.X” with the 2-digit version number of the stable release of Bugzilla that you want - e.g. “4.4”.

If that’s not possible, you can download a tarball of Bugzilla.

Place Bugzilla in a suitable directory, accessible by the default web server user (probably apache or www-data). Good locations are either directly in the web server’s document directory (often /var/www/html) or in /usr/local, either with a symbolic link to the web server’s document directory or an alias in the web server’s configuration.


The default Bugzilla distribution is NOT designed to be placed in a cgi-bin directory. This includes any directory which is configured using the ScriptAlias directive of Apache.

3.2.4. Perl Modules

Bugzilla requires a number of Perl modules. You can install these globally using your system’s package manager, or install Bugzilla-only copies. At times, Bugzilla may require a version of a Perl module newer than the one your distribution packages, in which case you will need to install a Bugzilla-only copy of the newer version.

At this point you probably need to become root, e.g. by using su. You should remain as root until the end of the install. This can be avoided in some circumstances if you are a member of your webserver’s group, but being root is easier and will always work.

To check whether you have all the required modules, run:

./checksetup.pl --check-modules

You can run this command as many times as necessary.

If you have not already installed the necessary modules, and want to do it system-wide, invoke your package manager appropriately at this point. Alternatively, you can install all missing modules locally (i.e. just for Bugzilla) like this:

./install-module.pl --all

Or, you can pass an individual module name:

./install-module.pl <modulename>

3.2.5. Web Server

Any web server that is capable of running CGI scripts can be made to work. We have specific configuration instructions for the following:

3.2.6. Database Engine

Bugzilla supports MySQL (or MariaDB, its compatible counterpart), PostgreSQL, Oracle and SQLite as database servers. You only require one of these systems to make use of Bugzilla. MySQL or MariaDB are most commonly used. SQLite is good for trial installations as it requires no setup. Configure your server according to the instructions below:

3.2.7. localconfig

You should now change into the Bugzilla directory and run checksetup.pl, without any parameters:


checksetup.pl will write out a file called localconfig. This file contains the default settings for a number of Bugzilla parameters, the most important of which are the group your web server runs as, and information on how to connect to your database.

Load this file in your editor. You will need to check/change $db_driver and $db_pass, which are respectively the type of the database you are using and the password for the bugs database user you have created. $db_driver can be either mysql, Pg (PostgreSQL), Oracle or Sqlite. All values are case sensitive.

Set the value of $webservergroup to the group your web server runs as.

  • Fedora/Red Hat: apache

  • Debian/Ubuntu: www-data

  • Mac OS X: _www

  • Windows: ignore this setting; it does nothing

The other options in the localconfig file are documented by their accompanying comments. If you have a non-standard database setup, you may need to change one or more of the other $db_* parameters.


If you are using Oracle, $db_name should be set to the SID name of your database (e.g. XE if you are using Oracle XE).

3.2.8. checksetup.pl

Next, run checksetup.pl an additional time:


It reconfirms that all the modules are present, and notices the altered localconfig file, which it assumes you have edited to your satisfaction. It compiles the UI templates, connects to the database using the bugs user you created and the password you defined, and creates the bugs database and the tables therein.

After that, it asks for details of an administrator account. Bugzilla can have multiple administrators - you can create more later - but it needs one to start off with. Enter the email address of an administrator, his or her full name, and a suitable Bugzilla password.

checksetup.pl will then finish. You may rerun checksetup.pl at any time if you wish.

3.2.9. Success

Your Bugzilla should now be working. Check by running:

./testserver.pl http://<your-bugzilla-server>/

If that passes, access http://<your-bugzilla-server>/ in your browser - you should see the Bugzilla front page. Of course, if you installed Bugzilla in a subdirectory, make sure that’s in the URL.

Next, do the Essential Post-Installation Configuration.
