Post subject:  Zoneminder and R7.00.03
Anyone installed this? My first attempt was concerning:
Code:
sudo pacman -S zoneminder
resolving dependencies...
looking for inter-conflicts...

Targets (15): jre-6u23-4  cambozola-0.92-1  apr-1.4.2-1  unixodbc-2.3.0-1
              apr-util-1.3.12-2  apache-2.2.17-1  perl-php-serialization-0.27-2

I already have lighttpd installed, is it going to be removed in favor of apache?

Install the package:
Code:
pacman -S zoneminder


Code:
sudoedit /etc/sysctl.conf

and append these two lines:
Quote:
kernel.shmall = 134217728
kernel.shmmax = 134217728

Code:
sudo /sbin/sysctl -p /etc/sysctl.conf

to make settings take effect

Fix the zm.conf so you can initialize the database:
Code:
 echo ZM_PATH_UPDATE=/usr/lib/zm/upgrade | sudo tee -a /etc/zm.conf


Initialize database:
Code:
sudo /usr/lib/zm/bin/zminit


Code:
sudoedit /etc/lighttpd/lighttpd.conf

and uncomment mod_alias and then append.

Code:
sudoedit /etc/lighttpd/conf.include

Quote:
alias.url = (
"/cgi-bin" => "/srv/zoneminder/cgi-bin/",
"/zm" => "/srv/zoneminder/www/"
)


restart lighttpd
Code:
sudo killall lighttpd


Fix log permissions
Code:
mkdir /var/log/zm
sudo chown -R http:http /var/log/zm


Fix data directory permissions
Code:
sudo chown -R http:http /var/lib/zm


Configure logrotate to notify zoneminder when log files have been rotated:
Code:
sudoedit /etc/logrotate.d/zm


and add
Quote:
postrotate
/usr/lib/zm/bin/zmpkg.pl logrot
endscript

below in the /var/log/zm/*log section

Have zm run at boot-up
Code:
sudo add_service.sh zm


Use you favorite web browser to configure zoneminder.

Excellent. I had used generic settings for shmmax and shmall unil I came across this script that will calculate recommended values.
