Ubuntu 22.04+ (Jammy)
---------------------
These instructions are for a brand new ubuntu 22.04 LTS system or newer which does not have ZM installed.

**Step 1:** Update system

::

    sudo apt-get update && sudo apt upgrade -y

**Step 2:** Update repositories (Optional)

ZoneMinder is part of the current standard Ubuntu repository, but sometimes the official repository can lag behind.
To find out check our `releases page <https://github.com/ZoneMinder/zoneminder/releases>`_ for the latest release.
    
Alternatively, the ZoneMinder project team maintains a `PPA <https://askubuntu.com/questions/4983/what-are-ppas-and-how-do-i-use-them>`_, which is updated immediately following a new release of ZoneMinder.
To use this repository instead of the official Ubuntu repository, enter the following commands:

::

        sudo apt install -y software-properties-common
        sudo add-apt-repository ppa:iconnor/zoneminder-1.36
        sudo apt update

**Step 3:** Configuration MySQL/MariaDB

::

	apt-get install mysql-server

Alternatively

::

  apt-get install mariadb-server

**Step 4:** Configure the ZoneMinder Database

This step is not required if you are using our ppa packages as they will do it for you.  It is ok to do it yourself though.

::

	sudo mysql --defaults-file=/etc/mysql/debian.cnf -p < /usr/share/zoneminder/db/zm_create.sql
	sudo mysql --defaults-file=/etc/mysql/debian.cnf -p -e "grant lock tables,alter,drop,select,insert,update,delete,create,index,alter routine,create routine, trigger,execute,references on zm.* to 'zmuser'@localhost identified by 'zmpass';"

**Step 5:** Install Zoneminder

::

        sudo apt install -y zoneminder


**Step 6:** Set permissions

If you plan to use local USB or V4L2 cameras (``/dev/video*``), the web server
user must be in the ``video`` group. The package postinst script does this
automatically, but if you installed from source or the group was not added, run:

::

        sudo adduser www-data video

You will need to restart ZoneMinder (or reboot) for the group change to take effect.

**Step 7:** Configure Apache correctly:

::

        sudo a2enmod rewrite headers cgi
        sudo a2enconf zoneminder
        sudo systemctl restart apache2


**Step 8:** Enable and start zoneminder

::

        sudo systemctl enable zoneminder
        sudo systemctl start zoneminder

**Step 9:** Open Zoneminder

Open up a browser and go to ``http://hostname_or_ip/zm`` to open the ZoneMinder Console.

Ubuntu 18.04 (Bionic)
---------------------
These instructions are for a brand new ubuntu 18.04 system which does not have ZM
installed.


It is recommended that you use an Ubuntu Server install and select the LAMP option
during install to install Apache, MySQL and PHP. If you failed to do this you can
achieve the same result by running:

::

    sudo apt-get install tasksel
    sudo tasksel install lamp-server

Installing LAMP is not ZoneMinder specific so you will find plenty of resources to 
guide you with a quick search.

**Step 1:** Either run commands in this install using sudo or use the below to become root
::

    sudo -i

**Step 2:** Update Repos

.. topic :: Latest Release

    ZoneMinder is now part of the current standard Ubuntu repository, but
    sometimes the official repository can lag behind. To find out check our
    `releases page <https://github.com/ZoneMinder/zoneminder/releases>`_ for
    the latest release.
    
    Alternatively, the ZoneMinder project team maintains a `PPA <https://askubuntu.com/questions/4983/what-are-ppas-and-how-do-i-use-them>`_, which is updated immediately
    following a new release of ZoneMinder. To use this repository instead of the
    official Ubuntu repository, enter the following from the command line:

    ::

        add-apt-repository ppa:iconnor/zoneminder-1.36

Update repo and upgrade.

::

	      apt-get update
        apt-get dist-upgrade


**Step 3:** Configure MySQL

.. sidebar :: Note

    The MySQL default configuration file (/etc/mysql/mysql.cnf) is read through
    several symbolic links beginning with /etc/mysql/my.cnf as follows:

    | /etc/mysql/my.cnf -> /etc/alternatives/my.cnf
    | /etc/alternatives/my.cnf -> /etc/mysql/mysql.cnf
    | /etc/mysql/mysql.cnf is a basic file

Certain new defaults in MySQL 5.7 cause some issues with ZoneMinder < 1.32.0,
the workaround is to modify the sql_mode setting of MySQL. Please note that these 
changes are NOT required for ZoneMinder 1.32+ and some people have reported them 
causing problems in 1.32.0.

To better manage the MySQL server it is recommended to copy the sample config file and
replace the default my.cnf symbolic link.

::

        rm /etc/mysql/my.cnf  (this removes the current symbolic link)
        cp /etc/mysql/mysql.conf.d/mysqld.cnf /etc/mysql/my.cnf

To change MySQL settings:

::

        nano /etc/mysql/my.cnf

In the [mysqld] section add the following

::

        sql_mode = NO_ENGINE_SUBSTITUTION

CTRL+o then [Enter] to save

CTRL+x to exit

Restart MySQL

::

        systemctl restart mysql


**Step 4:** Install ZoneMinder

::

	apt-get install zoneminder

**Step 5:** Configure the ZoneMinder Database

This step should not be required on ZoneMinder 1.32.0.

::

	mysql -uroot -p < /usr/share/zoneminder/db/zm_create.sql
	mysql -uroot -p -e "grant lock tables,alter,drop,select,insert,update,delete,create,index,alter routine,create routine, trigger,execute,references on zm.* to 'zmuser'@localhost identified by 'zmpass';"


**Step 6:** Set permissions

Set /etc/zm/zm.conf to root:www-data 740 and www-data access to content

::

        chmod 740 /etc/zm/zm.conf
        chown root:www-data /etc/zm/zm.conf

If you plan to use local USB or V4L2 cameras (``/dev/video*``), add the web server
user to the ``video`` group:

::

        sudo adduser www-data video

**Step 7:** Configure Apache correctly:

::

        a2enmod cgi
        a2enmod rewrite
        a2enconf zoneminder

You may also want to enable to following modules to improve caching performance

::

         a2enmod expires
         a2enmod headers

**Step 8:** Enable and start Zoneminder

::

        systemctl enable zoneminder
        systemctl start zoneminder

CTRL+o then [Enter] to save

CTRL+x to exit

**Step 10:** Reload Apache service

::

	systemctl reload apache2

**Step 11:** Making sure ZoneMinder works

1. Open up a browser and go to ``http://hostname_or_ip/zm`` - should bring up ZoneMinder Console

2. (Optional API Check)Open up a tab in the same browser and go to ``http://hostname_or_ip/zm/api/host/getVersion.json``

    If it is working correctly you should get version information similar to the example below:

    ::

            {
                "version": "1.34.0",
                "apiversion": "1.34.0.1"
            }

**Congratulations**  Your installation is complete

PPA install may need some tweaking of ZMS_PATH in ZoneMinder options. `Socket_sendto or no live streaming`_


Harder Way: Build Package From Source (Discouraged)
---------------------------------------------------
Historically, installing ZoneMinder onto your system required building from source code by issuing the traditional configure, make, make install commands. To get ZoneMinder to build, all of its dependencies had to be determined and installed beforehand. Init and logrotate scripts had to be manually copied into place following the build. Optional packages such as jscalendar and Cambozola had to be manually installed. Uninstalls could leave stale files around, which could cause problems during an upgrade. Speaking of upgrades, when it comes time to upgrade all these manual steps must be repeated again.

Better methods exist today that do much of this for you. The current development team, along with other volunteers, have taken great strides in providing the resources necessary to avoid building from source.

(These instructions assume installation from source on a ubuntu 15.x+ system)

**Step 1:** Grab the package installer script

::

	wget https://raw.githubusercontent.com/ZoneMinder/ZoneMinder/master/utils/do_debian_package.sh
	chmod a+x do_debian_package.sh


**Step 2:** Update the system

::

	sudo apt-get update


**Step 3** Create the package

To build the latest master snapshot:

::

	./do_debian_package.sh --snapshot=NOW --branch=master --type=local


To build the latest stable release:

::

	./do_debian_package.sh --snapshot=stable --type=local


Note that the distribution will be guessed using ``lsb_release -a 2>/dev/null | grep Codename | awk '{print $2}'``
which simply extracts your distribution name - like "bionic", "hirsute" etc. You
can always specify it using --distro=your distro name if you know it. As far as the script
goes, it checks if your distro is "trusty" in which case it pulls in pre-systemd
release configurations and if its not "trusty" it assumes its based on systemd
and pulls in systemd related config files.

(At the end the script will ask if you want to retain the checked out version of
ZoneMinder. If you are a developer and are making local changes, make sure you
select "y" so that the next time you do the build process mentioned here, it
keeps your changes. Selecting any other value than "y" or "Y" will delete the
checked out code and only retain the package)

This should now create a bunch of .deb files

**Step 4:** Install the package

::

	sudo gdebi zoneminder_<version>_<arch>.deb
	(example sudo gdebi zoneminder_1.34.0-bionic-2021020801_amd64.deb)


**This will report DB errors - ignore - you need to configure the DB and some other stuff**

**Step 5:** Post install configuration

Now that you have installed from your own package you can resume following the
standard install guide for your version, start at the step after Install Zoneminder.

Hints
-----
Make sure ZoneMinder and APIs work with security
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1. Enable OPT_AUTH in ZoneMinder
2. Log out of ZoneMinder in browser
3. Open a new tab in the *same browser* (important) and go to
   ``http://localhost/zm/api/host/getVersion.json`` - should give you "Unauthorized"
   along with a lot more of text
4. Go to another tab in the SAME BROWSER (important) and log into ZM
5. Repeat step 3 and it should give you the ZM and API version

Socket_sendto or no live streaming
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

After you have setup your camera make sure you can view Monitor streams, if not
check some of the common causes:

* Check Apache cgi module is enabled.
* Check Apache /etc/apache2/conf-enabled/zoneminder.conf ScriptAlias matches PATH_ZMS.

        ScriptAlias **/zm/cgi-bin** /usr/lib/zoneminder/cgi-bin

        From console go to ``Options->Path`` and make sure PATH_ZMS is set to **/zm/cgi-bin/**\ nph-zms.


Changed Default DB User
^^^^^^^^^^^^^^^^^^^^^^^

If you have changed your DB login/password from zmuser/zmpass, you need to
update these values in zm.conf.

1. Edit zm.conf to change ZM_DB_USER and ZM_DB_PASS to the values you used.
