If you plan to install Domino V11 on CentOS 8.1 you have to do some steps before because there are some requirements:

Install CentOS 8.1.x ( without any graphical interface – you won´t need it )

• Install perl
  • To run the Domino console installation you need perl to run it
  • yum install perl
• I don´t exactly know if the libXp library is also needed ( it was in the last releases ) but I installed it
  • yum install libXp

Afterwards I created the default user und group for the Domino Server:

• sudo groupadd notes
• sudo adduser notes
  • To add the user “notes” to the group
    • sudo usermod -g notes notes
• Set up the notes user to use DOMINO_LINUX_SET_PARMS:
  • # vi /home/notes/.bashrc
  • Add to the end of the file: export DOMINO_LINUX_SET_PARMS=1
• Update the Security/Limits File:
  • Edit /etc/security/limits.conf using root and add or modify the lines:
    • notes soft nofile 65535
    • notes hard nofile 65535
  • (Use 65535 for 64 bit Linux for both soft and hard limits, per HCL 2019/12.
• Update SELINUX:
  • $ vi /etc/selinux/config
    Change to SELINUX=disabled and save.

Then you have to check if the firewall is active – you can do this with the following command:

• firewall-cmd –state
• If it´s running you can stop and disable it with
  • systemctl firewalld stop
  • systemctl disable firewalld
• or you have to add the rules for running your Domino V11 server for the required ports
  • 1352
  • 80/443
  • 25
  • 389
  • …

Afterwards you just have to install your Domino V11 server, implement the perfect start/stop scripts of Daniel Nashed ( which are extremely well documentated ), configure your Domino server and run a great collaboration tool !!
