• Check of pre-requisites

When accessing http://localhost/zabbix/queue.php, we have to pass all the checking as follows:
vi /etc/php.ini to change:
timezone = Australia/Sydney
post_max_size = 32M
upload_max_filesize = 2M
max_execution_time = 600  
max_input_time = 600 

yum install php-mbstring
yum install php-gd

• PHP and PHP53

When you use yum to install php* , you can exclude php53* as follows:

vi /etc/yum.conf to add
exclude=php53*

or yum install php* --exclude=php53*
