What's New
==========
1. The Apache ScriptAlias has been changed from "/cgi-bin/zm/zms" to
"/cgi-bin-zm/zms". This has been to done to avoid this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=973067
IMPORTANT: ZoneMinder will not update this value on an upgrade. You must
manually update ZM_PATH_ZMS yourself under Options. This does not affect
new installs.
2. ZoneMinder no longer uses PHP short tags.
3. During an rpm package upgrade, zmupdate.pl will now auto-update the database
and the zonemidner service will restart automatically.
4. The ZoneMinder config file, zm.conf, has been moved under /etc/zm.
5. Systemd. CentOS 7 uses Systemd instead of the legacy Sys V Init. Under the
hood, Systemd does things quite a bit differently. Prepare to go through a
learning curve if you have not done so already.
New installs
============
1. Unless you are already using MariaDB server, you need to ensure that
the server is configured to start during boot and properly secured
by running:
sudo systemctl enable mariadb
sudo systemctl start mariadb
sudo mysql_secure_installation
2. Using the password for the root account set during the previous step, you
will need to create the ZoneMinder database and configure a database
account for ZoneMinder to use:
mysql -u root -p < /usr/share/zoneminder/db/zm_create.sql
mysql -u root -p
mysql> grant select,insert,update,delete,lock tables,alter on zm.* to
'zmuser'@localhost identified by 'zmpass';
mysql> exit;
mysqladmin -u root -p reload
The database account credentials, zmuser/zmpass, are arbitrary. Set them to
anything that suits your envinroment.
3. If you have chosen to change the zoneminder database account credentials to
something other than zmuser/zmpass, you must now edit /etc/zm/zm.conf.
Change ZM_DB_USER and ZM_DB_PASS to the values you created in the previous
step.
4. Edit /etc/php.ini, uncomment the date.timezone line, and add your local
timezone. For whatever reason, PHP will complain loudly if this is not set,
or if it is set incorrectly, and these complaints will show up in the
zoneminder logging system as errors.
If you are not sure of the proper timezone specification to use, look at
http://php.net/date.timezone
5. This package will automatically configure and install an SELinux policy
called local_zoneminder. A copy of this policy is in the documentation
folder.
Maintaining an accurate SELinux policy file that does not create issues has
been a struggle. If SELinux blocks nortmal ZoneMinder acitivity, or you
feel you just don't need it, SELinux can be disabled for the current running
session with the following command:
sudo setenforce 0
To permanently disable SELinux, edit /etc/selinux/conf and change the
SELINUX line from "enforcing" to "disabled". This change will take
effect after a reboot.
8. Now start the web server:
sudo systemctl enable httpd
sudo systemctl start httpd
9. Now start zoneminder:
sudo systemctl enable zoneminder
sudo systemctl start zoneminder
Upgrades
========
1. Verify /etc/zm/zm.conf.
If zm.conf was manually edited before running the upgrade, the installation
may not overwrite it. In this case, it will create the file
/etc/zm/zm.conf.rpmnew.
For example, this will happen if you are using database account credentials
other than zmuser/zmpass.
Compare /etc/zm/zm.conf to /etc/zm/zm.conf.rpmnew. Verify that zm.conf
contains any new config settings that may be in zm.conf.rpmnew.
2. Verify permissions of the zmuser account.
Overtime, the database account permissions required for normal operation
have changed. Verify the zmuser database account has been granted select,
insert, update, delete, lock tables, and alter permission to the ZoneMinder
database:
mysql -u root -p
mysql> show grants for zmuser@localhost;
mysql> exit;
3. Verify the database was upgraded automatically.
From the web console, ZoneMinder should show a status of "Running", and the
version number should have incremented.
If it is not running, then try to start it. The web console will indicate
if there is a database version conflict. If this is the case, then you may
need to manually update the database from the command line:
sudo zmupdate.pl
Modern versions of ZoneMinder don't require any parameters added to the
zmupdate command. However, if ZoneMinder complains, you may need to call
zmupdate in the following manner:
sudo zmupdate.pl --user=root --pass=<mysql_root_pwd> --version=<from version>
