Installation of CheckMK 1.6 on CentOS 8 fails with dependencies

Troubleshooting
1

Trying to install the check-mk-raw-1.6.0p8-el8-38.x86_64.rpm file which is the installer for CentOS. We have a CentOS 8 here which is officially supported according to the download page. Going by the installation instructions there is no special handling necessary for CentOS 8 and CheckMK 1.6.

yum install check-mk-raw-1.6.0p8-el8-38.x86_64.rpm

gives:

Adding additional repositories remedies some of these dependencies, however, this unfilled dependency remains:

  • nothing provides libdbi needed by check-mk-raw-1.6.0p8-el8-38.x86_64

libdbi is not available for CentOS 8.

Usually i do this previous dependencies installations:

yum install epel-release

yum install time traceroute dialog fping graphviz graphviz-gd httpd libevent libdbi rpcbind net-snmp net-snmp-utils perl-Net-SNMP perl-Locale-Maketext-Simple perl-IO-Zlib php php-cli php-xml php-mbstring php-pdo php-gd rsync uuid xinetd freeradius-utils libpcap bind-utils poppler-utils libgsf rpm-build

Usually i don’t need any other deps.

Cheers,

Hi,
libdbi is in the EPEL-Repository. If you plan to use NagVis, then install the php-json-package also.

Thanks for the suggestion. After installing epel-release, it doesn’t fare much better:

I’m new to the CentOS/Redhat sphere, so I might miss something obvious.

Hi,

yum repolist all | grep "AppStream"

I think the AppStream-Repository is deactivated. That’s the problem.
Do you have the file /etc/yum.repos.d/CentOS-AppStream.repo?
You can change the setting from enabled=0 to enabled=1

After that test with the command:

yum search httpd

Karl

You were right, that repo was deactivated. After enabling it, the

dnf localinstall check-mk-raw-1.6.0p8-el8-38.x86_64.rpm

works. What I am taking away from this is that CentOS 8 is supported, but the documentation is out of date, as it says that this extra work that went into that now is only listed for previous CentOS versions.

Thank you!

Hi,
install php-json if you want to use NagVis. This package is missing in the dependency list of CMK.
