  2. Create a directory for .
    su - <username> -c "mkdir /home/<username>/<directory_name>"
  3. Create a file called /etc/security/limits.d/25-phantom-limits.conf. This file sets resource limits for the user that will run .
    touch /etc/security/limits.d/25-phantom-limits.conf
  4. Edit the file /etc/security/limits.d/25-phantom-limits.conf to add these settings:
    <username>          hard    nofile          64000
    <username>          soft    nofile          64000
    <username>          hard    nproc           64000
    <username>          soft    nproc           64000

    sysctl --system

Install from the tar file

  1. Log in as the user that will run . Do not perform these steps as the root user.
