How To Uninstall / Remove Synology Cloud Station On Ubuntu

There isn’t a clear way to uninstall the Synology Cloud Station client on Ubuntu from the GUI. The only ways seems to be from the command line and it took me a while to find it.

Cloud Station is installed in your home directory in a hidden folder called ./Cloudstation. There is an uninstall script buried in a few folders down.

Open a terminal and run:


Job done.

WordPress / MySQL keeps crashing on Ubuntu / Digital Ocean

I host a couple of WordPress sites on Ubuntu hosted on Digital Ocean droplets. I use their standard WordPress application (pre built WordPress on Ubuntu) with the smallest size Droplet possible. It has just 512MB Ram and 20GB SSD Disk and 1 logical core – i.e. it isn’t very quick.

Anyhow, I started to have a few problems with MySQL crash. I manifested itself by WordPress complaining that it could not connect to the database. I could fix the problem by restarting MySQL – ‘sudo service mysql restart’.

The longterm fix is to give MySQL more memory but I didn’t really want to do that. So, I opted to provide the server with more swap space. Given that Digital Ocean server are SSD’s this would be quite quick.

Here is how you add swap to an Ubuntu server:

1 – Check you what swap you have.

sudo swapon -s

If you get blank response then you don’t have any swap. Digital Ocean doesn’t seem to provide swap by default.

2 – Check how much disk space you have.

df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            234M     0  234M   0% /dev
tmpfs            49M  528K   49M   2% /run
/dev/vda1        20G  2.3G   17G  12% /
tmpfs           245M     0  245M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           245M     0  245M   0% /sys/fs/cgroup
tmpfs            49M     0   49M   0% /run/user/1000

I had 17G and so could easily give the server 1g swap.

3 – Use fallocate to reserve space on the file system. Fallocate is used because it doesn’t bother to write anything to the file system. It just allocates the space on the disk.

sudo fallocate -l 4G /swapfile

4 – Set file permissions

sudo chmod 600 /swapfile

5 – Convert it to a swap file

sudo mkswap /swapfile

6 – Add the swap

sudo swapon /swapfile

7 – Check that the swap is there

sudo swapon -s

8 – Add it to the fstab
so that it is mounted when the server reboots

sudo nano /etc/fstab

and put this line at the bottom:

/swapfile   none    swap    sw    0   0

Finally, you can check it has all worked…

sudo swapon -s
Filename				Type		Size	Used	Priority
/swapfile                              	file    	1194300	103160	-1
