OpenSuse Notes
|
||||
===============
|
||||
|
||||
1. OpenSuse, along with other distros, now use systemd for task control.
|
||||
One of the capabilties of systemd is to use private space for /tmp to reduce
|
||||
the possibility of cross talk between applications. The default settings
|
||||
for zoneminder use /tmp for a number of files. When you start/stop
|
||||
zoneminder from a web page /tmp will be in private space but when the
|
||||
start/stop script zmpkg.pl is run from a shell it will be looking in the
|
||||
real /tmp. This can result in two instances of zoneminder running at
|
||||
the same time.
|
||||
|
||||
In order to remove this problem the OpenSuse rpm defaults the temporary
|
||||
directory to /var/run/zoneminder. For a new install this will not be a
|
||||
problem but if you use the rpm to upgrade you may have to make database
|
||||
changes.
|
||||
|
||||
Note: the location is held both within the database an explicitly within some
|
||||
scripts. It is therefore essential that the database conforms to the values
|
||||
used in the scripts. Please see information in the Upgrades section of this
|
||||
document.
|
||||
|
||||
2. OpenSuse prefers mariadb to mysql. mariadb is a direct replacement for mysql
|
||||
and all mysql functions work in the same way. These notes assumes that you
|
||||
are running mariadb.

1. Unless you are already using the MySQL server or you are running it

remotely you will need to ensure that the server is installed and secured:

|

NOTE: the default database for OpenSuse is mariadb, which is a direct
|
||||
replacement for mysql
|
||||
|
||||
IMPORTANT: mariadb defaults to strict mode of operation which will cause
|
||||
some zoneminder database writes to fail.
|
||||
In order to turn this off - which will be for the whole database you will
|
||||
need to edit /etc/my.cnf and comment out the record

*********** This needs checking for OpenSuse
|
||||
|
||||
The httpd.conf file included with this version of Fedora processes the conf.d
|
||||
folder after the default ScriptAlias directive in the httpd.conf file.
|
||||
Previously, the conf.d folder was processed before the default ScriptAlias
|
||||
directive. This causes a ScriptAlias overlap and breaks Zoneminder's
|
||||
streaming abilities.

|
||||
|
||||
WORKAROUND #1
|
||||
If you are running zoneminder on a dedicated server then the simplest
|
||||
solution may be to simply comment out the line in httpd.conf that reads:
|
||||
|
||||
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
|
||||
|
||||
WORKAROUND #2
|
||||
If you need both the default cgi-bin folder & the zoneminder cgi-bin folder
|
||||
then a solution might be to move the following line before the default
|
||||
ScriptAlias directive in the httpd.conf file:
|
||||
|
||||
IncludeOptional conf.d/*.conf
|
||||
|
||||
8. Now start the web server:

sudo systemctl start apache2.service

10. ************ Check for OpenSuse
|

10. You should be able to start zoneminder by issuing the commands (as root):
|
||||
|
||||
The zoneminder.service file fails at present but the zmpkg.pl script
|
||||
can be run as root to start zoneminder.
|
||||
systemctl enable zoneminder
|
||||
systemctl start zoneminder
|
||||
|
||||
sudo zmpkg.pl start
|
||||
If zoneminder fails to start using the service you may also start it
|
||||
with this command:
|
||||
|
||||
To start zoneminder automatically, create /etc/rc.d/rc.local and place the
|
||||
following inside it:
|
||||
#!/bin/sh
|
||||
/usr/bin/zmpkg.pl start
|
||||
/opt/zoneminder/bin/zmpkg.pl start
|
||||
|
||||
The rc.local file must be made executable.

2. Add the mysql ALTER permission to the zmuser account:

||||
|

mysql -u root -p

grant alter on zm.* to

'zmuser'@localhost identified by 'zmpass';
|
||||
use zm
|
||||
grant alter, lock tables on zm.* to 'zmuser'@localhost;
|
||||
|
||||
Since this is an upgrade, the assumption is that the zmuser account already
|
||||
has select, insert, update, and delete permission.
|
||||
|
||||
3. You will need to upgrade the ZoneMinder database as described in the
|
||||
manual. Only if the previous step was succesful, may you run zmupdate like
|
||||
so:

so (as root):
|
||||

sudo /opt/zoneminder/bin/zmupdate.pl --version=<from version>

/opt/zoneminder/bin/zmupdate.pl
|
||||
|
||||
|
||||
If unsure then run it this way:
|
||||
4. As mentioned in the OpenSuse notes you may need to change database values.
|
||||
These steps may be run at any time (as root):
|
||||
|
||||
sudo zmupdate.pl --user=root --pass=<mysql_root_pwd> --version=<from version>
|
||||
stop the current instance of zoneminder - systemctl stop zoneminder
|
||||
|
||||
4. To overcome a problem when applications my use private /tmp space when systemd is used
|
||||
the OpenSuse rpm has changed the default directory for temporary files from /tmp to
|
||||
/var/run/zoneminder. Whilst this change is directly inside the scripts, it does not,
|
||||
at present, change the values held in the database.
|
||||
You must therefore manually modify the database as follows:
|
||||
ensure that all zoneminder processes have terminated:
|
||||
|
||||
**** needs more information
|
||||
ps -ef|grep zm
|
||||
if you find any process still running issue a kill -9 for each
|
||||
|
||||
mysql -u root
|
||||
use zm
|
||||
update Config set DefaultValue = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_LOGS';
|
||||
update Config set Value = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_LOGS';
|
||||
update Config set DefaultValue = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_SOCKS';
|
||||
update Config set Value = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_SOCKS';
|
||||
update Config set DefaultValue = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_LOGS';
|
||||
update Config set Value = '/var/run/zoneminder'
|
||||
where name = 'ZM_PATH_SWAP';
|
||||
commit;
|
||||
exit
|
||||
|
||||
|
||||
You can then restart zoneminder - systemctl start zoneminder
