Note for mysql:
==> To run Zoneminder, you must install the database running mysql service (as root):
==> "systemctl start mysqld.service"
==> and add Zoneminder database typing (with passsword):
==> "mysqladmin --defaults-file=/etc/mysql/my.cnf -p -f reload"
==> "cat /usr/share/zoneminder/db/zm_create.sql | mysql --defaults-file=/etc/mysql/my.cnf -p"
==> "echo 'grant lock tables, alter,select,insert,update,delete on zm.* to 'zmuser'@localhost identified by "zmpass";' | mysql --defaults-file=/etc/mysql/my.cnf -p mysql"

==> "mysqladmin --defaults-file=/etc/mysql/my.cnf -f reload"

==> "echo 'grant lock tables, alter,select,insert,update,delete on zm.* to 'zmuser'@localhost identified by "zmpass";' | mysql --defaults-file=/etc/mysql/my.cnf mysql"

Note for php:

==> "extension=mysqli.so"
==> "extension=session.so"
==> "extension=sockets.so"
==> "extension=openssl.so"
==> "extension=ftp.so"

==> check and add to open_basedir "/etc" and
==> "/srv/http/zoneminder" like so
==> "open_basedir = /home:/tmp:/usr/share/pear:/etc:/srv/http/zoneminder"
==> and set your timezone in php.ini:
==> "date.timezone = <your_country>/<your_city>"

Note for apache:
==> You must edit /etc/httpd/conf/httpd.conf and add the line:
==> "LoadModule php5_module modules/libphp5.so"
