Hi, sathiya !

Please specify what kind of installation you are trying to perform - from repo, packages or you are trying to build from source ?

If you are new with linux/Zabbix - better choose an option to install from repo. Installing from repo will also install the components, which are necessary to run Zabbix.

From now it looks like you are trying to build from sources, so you need to specify which database engine you want to use and also install additional PHP elements.

Please, go through the Zabbix documentation to get more info about the installation process:

Alex!

PHP extension missing

Thanks Alex,

We have RHEL 6 version
And we are trying to install from repo but getting error while installing the php components.
we tried the below command:
php -i | grep extension_dir ---------->>Unable to load dynamic library '/usr/lib64/php/modules/php_mbstring.so',php_gd2.so , pgsql.so

but it didnt work hence we tried yum command:
sudo yum install php-mbstring -------------->>No package php-mbstring available
still not working, could you please advice how to install these PHP modules or can we download php extnsion ( *.so files ) ?

Hi sathiya,
First thing you need to check is your PHP version. The PHP version required for 3.2 is 5.4 or newer. I believe that you have older one.

Also, in any case, use yum search <string> to find the right package name.

P.S. - By the way, is it mandatory to use REHL v6 or you can upgrade to newer and use REHL v7 ? https://www.zabbix.com/documentation...y_installation

Hi Allex,

Yes you are correct, the PHP version which we have is 5.3 and obviously it will not work in this case.

we started the installation since we had RHEL 6 server in ready state, but it is not mandatory to use the same version.

we can have RHEL 7 as well, so you mean to say RHEL 7 version will have all the required PHP components by default (for 3.2 installation)? and we can avoid this issue?
