It is perfect for creating a course reference base for an educational organisation, for making a QnA list in the IT, for exchanging knowledge within social work teams, for making a thematic list of personal quotes and notes.

Running Sidekiq in production using Systemd

To setup a Sidekiq Systemd service, you need a service configuration file. An example file can be found in the Sidekiq github repo.

• Copy this file to your server and place it in /lib/systemd/system There are two lines here that require adjustment to your settings;

  1. The working directory path, change this to you application path, for example:
     WorkingDirectory=/home/deploy/my_app/current
  2. The ExecStart path. This specifies the path and command to start Sidekiq. Now this could be different depending on your settings and ruby version managers (if you use one). For example:
     ExecStart=/home/deploy/.rbenv/shims/bundle exec sidekiq -e production

• After setting up configuration, enable the Sidekiq service with:
  sudo systemctl enable

• Other commands:

  systemctl stop sidekiq  
  systemctl start sidekiq
  systemctl restart sidekiq
  systemctl kill -s TSTP sidekiq # quiet
  

Change swap size in Ubuntu 18.04

To generate OGImages, recommended to increase size of the swap file
In the following example, we’ll extend the swap space available in the /swapfile to 8 GB

• Turn off all swap processes
  • sudo swapoff -a
• Resize the swap
  • sudo dd if=/dev/zero of=/swapfile bs=1G count=8
    if = input file
    of = output file
    bs = block size
    count = multiplier of blocks
• Make the file usable as swap
  • sudo mkswap /swapfile
• Activate the swap file
  • sudo swapon /swapfile
• Check the amount of swap available
  • grep SwapTotal /proc/meminf
