Hello, in this tutorial, you will learn how to increase the memory of your VPS (Linux virtual machine) or your WordPress site. You can add a swap file for VM instance to increase memory. If you want to know to get free VPS, check the VPS and Mining Playlist of the channel.
Open the terminal of your VPS or WordPress VM instances using an SSH connection.
To see available Memory and swap file size, use this command. You can see there is no swap file.
Create a swap file and allocate space. I’ve used 1024 MB but you can take more.
sudo dd if=/dev/zero of=/mnt/swap.0 bs=1024 count=1048576
Next use this line to mount it.
sudo mkswap /mnt/swap.0
Switch to root account to activate the swap.
Use this to activate it.
echo "/mnt/swap.0 swap swap defaults 0 0" >> /etc/fstab
Next use this command.
check if it’s created successfully.
sudo swapon -s
Check again the created main and swap size for memory. The swap file is created successfully.
