Deployment Guide

Save the file and restart SSH daemon:
# service sshd restart
Consider using SSH keys instead of password login
Generally, an SSH public key login is more secure than password logins.
4.1.4 Operating system limits
The default number of allowed OS threads may not be sufficient for larger Sapphire installations. It is
suggested to double the allowed “carat7” process threads from 1024 to 2048.
Open the file /etc/security/limits.d/90-nproc.conf in an editor. Add the line in red to the file and save the file.
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 1024
carat7 soft nproc 4096
root soft nproc unlimited
If you are modifying the file after installing the Carat server, restart the server in order to get the new limits
into use:
# 7carat restart
