Server software prerequisites

InfoPrint Manager for Linux requires the 64-bit Linux (x86_64) operating system to be installed at one of these distributions:

  • CentOS Linux 7 x86_64
  • CentOS Linux 8 x86_64 (up to version 8.4)
  • Oracle Linux 7 x86_64 (version 7.5 or later)
  • Red Hat Enterprise Linux Server 7 x86_64
  • Red Hat Enterprise Linux Server 8 x86_64
  • SUSE Linux Enterprise Server 12 x86_64
  • SUSE Linux Enterprise Server 15 x86_64
    Important:
  • If tuned daemon is running on an RHEL 7, it must not be allowed to modify the kernel parameter kernel.sched_min_granularity_ns.
  • If you run InfoPrint Manager as root, you must set: ROOT_USES_LANG variable from /etc/sysconfig/language file is set to yes.
  • The authorized user must be able to run the ping command. The package that provides this command is iputils. If the ping command is restricted to a certain group for security reasons, the authorized user must be a member of that certain group.

  • If you run InfoPrint Manager on CentOS Linux, RHEL, or SLES 12, before you run the installation, if the SystemGroup directive in the /etc/cups/cups-files.conf CUPS file does not contain the group of the InfoPrint Manager user, you must add it.
  • If the user does not exist and there is no group specified by the person installing (that is, ipm1), check if the sys group exists and create it if it does not exist. When you create the sys group, specify -r (system group). If the user does not exist and the group is specified (that is, ipm1:ipm1group), check if the ipm1group exists and create it if it does not exist without specifying system group. Then, create the user using the ipm1group group.
  • InfoPrint Manager needs /var/pd, /var/pddir, /var/psf, /var/psm, /tmp, and /var/tmp to be on a partition that permits execution of binaries. If any of those partitions is mounted with noexec mount option, it is impossible to install or run InfoPrint Manager.
