Of course, besides the package manager (apt), there are some differences between RHEL and Centreon:

 

Packages management

  RHEL Debian
Get list of repositories yum repolist grep ^[^#] /etc/apt/sources.list /etc/apt/sources.list.d/*
Clean cache yum clean all apt clean all
Create cache yum makecache apt update
Install a package yum install centreon-web apt install centreon-web
Update a package yum update centreon-web apt upgrade centreon-web
Reinstall a package yum reinstall centreon-trap apt reinstall centreon-trap
Search for a package yum search centreon-web apt search centreon-web
Get information about a package yum info centreon-web apt info centreon-web
Know which package provide a binary yum provides */centreontrapd dpkg -S centreontrapd
Interrogate list of installed package rpm -qa apt list --installed
Know which dependencies will be installed with a package yum deplist centreon-tra apt depends centreon-trap

 

Define proxy for packages manager

RHEL Debian

cat <<EOF >> /etc/yum.conf

proxy=http://10.0.0.133:3128

EOF

cat <<EOF >> /etc/apt/apt.conf.d/80proxy

Acquire::http::proxy "http://10.0.0.133:3128/";

Acquire::https::proxy "http://10.0.0.133:3128/";

Acquire::ftp::proxy "ftp://10.0.0.133:3128/";

EOF
