You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

what is the problem?? TT

[Atsushi]

Zabbix's official repository is made up of OS standard packages.
If the environment of PHP 7.2 which is not OS standard is installed, dependency of package can not be resolved, and installation with yum command may be impossible.

It is the easiest way to return to the OS standard PHP 5.4 environment.
If you are installing PHP 7.2 as it is, you can give up installing with the yum command and install the package of the Web front end by rpm command ignoring the dependency.

[ingus.vilnis]

If I remember correctly PHP packages from Webtatic repository replace CentOS PHP 5.4 packages without any additional woodoo magic. Remi packages don't.

[nameuser]

I have the same issue but with PHP7 from remi repo.

Any chance to fix it?

[nameuser]

I dont know why but removing IUS repository from repolist is solution.

So I did this:
1. yum remove php*
2. yum clean all
3. rm /etc/yum.repos.d/ius*
4. yum install zabbix-web-mysql

Hope you will solve this issue the same way.
Anyway, I don't know why removing 3rd party repo (ius) fix that for me

[steeladept]

Zabbix's official repository is made up of OS standard packages.
If the environment of PHP 7.2 which is not OS standard is installed, dependency of package can not be resolved, and installation with yum command may be impossible.

My experience is this isn't strictly correct. I have been using PHP 7.2 (remi) since the beginning without issue. The main difference between this build and mine (and the reason I required 7.2) was MySQL 8.0 was used.

I did have issues with the Webtatic repo, personally, but as Ingus mentioned, that may work better for the user. The key for me seemed to be to install and configure the PHP modules before starting the server. For some reason, when I installed and started the server, it seemed to set variables that I couldn't unset. Once I restarted from scratch, I did it in this order and it worked fine: 1) Install all Repos, 2) Install PHP 7.2 and then Zabbix components, 3) Configure PHP, 4) Start the server.

Honestly, it doesn't make sense to me why this works and the other way didn't. And perhaps there is a lot to be said about the variance of MySQL 8 components instead of MySQL 14.14 distrib 5.7.24 (whatever that is in the MySQL numbering equivalent); but I will say that sticking to the OS default 5.4 PHP is not a requirement.

It depends on the repository and version they use.
If they can not solve the problem themselves, I think they should use the default repository.

If they set up properly and they are using the latest packages, they can install without worrying about the order. The question of the first questioner is irrelevant whether it is MySQL 8.0 or not. It is a problem of php-mysql and php-mysqlnd dependency.

If they are using PHP 7.2 on remi to install Zabbix 4.0 in the CentOS 7 environment, just follow the steps below.

# yum update
# reboot
# yum install http://repo.zabbix.com/zabbix/4.0/rh...el7.noarch.rpm
# yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
# yum --enablerepo=remi-php72 install zabbix-get zabbix-server-mysql zabbix-web-mysql zabbix-agent

I actually tried creating the environment, but it seems to fail if PHP 7.2 is installed first.
If they want to reinstall PHP, they can install it by the following procedure.

# yum remove php-common
# yum --enablerepo=remi-php72 install zabbix-get zabbix-server-mysql zabbix-web-mysql zabbix-agent

PHP version specification in /etc/httpd/conf.d/zabbix.conf file is required.
(mod_php5.c -> mod_php7.c)

Just fixed it by installing php-pecl-mysql.x86_64 (remi package) and then zabbix-web-mysql.
Centos 7.6.1810, PHP 7.1 remi

If you are installing PHP 7.2 as it is, you can give up installing with the yum command and install the package of the Web front end by rpm command ignoring the dependency
