These are some very very brief instructions on how to install Motion on a CentOS 6 system.
Install Prerequisites
yum -y install gcc make
yum -y install libjpeg-turbo libjpeg-turbo-devel
Install Motion
Download Motion, e.g. as a .tgz from SourceForge:
cd /root/
wget http://downloads.sourceforge.net/project/motion/motion%20-%203.2/3.2.12/motion-3.2.12.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fmotion%2Ffiles%2Fmotion%2520-%25203.2%2F3.2.12%2F&ts=1385393313&use_mirror=garr
Untar:
tar zxvf motion-3.2.12.tar.gz
Install:
cd /root/motion-3.2.12/
./configure
make
make install
This will install motion in its default location, in subdirectories of
/usr/local/, e.g:
/usr/local/bin/for executables,/usr/local/man/for man pages,/usr/local/etc/for configuration files,/usr/local/docs/for documentation,/usr/local/share/for configuration examples, etc.
Finally, before starting motion you need to copy the default
configuration file motion-dist.conf to motion.conf (by default in
/usr/local/etc/.
