Swap Memory

To top

I found the solution,
seems that our droplets doesnt have enogh memory some times and mysql cant allocate what it needs and crash, so we need to create a swap space to help this.
this is what I did:
On the command line

root@myserver:~# dd if=/dev/zero of=/swap.dat bs=1024 count=512k
root@myserver:~# mkswap /swap.dat
root@myserver:~# swapon /swap.dat
root@myserver:~# vim /etc/fstab

vim is started to edit, add the following to the end of /etc/fstab file

/swap.dat      none    swap    sw      0       0

Then, edit the mysql config file

root@myserver:~# vim /etc/mysql/my.cnf

And add this under [mysqld]

innodb_buffer_pool_size=64M

Finally reload mysql

root@myserver:~#  service mysqld reload

How do I install the Firefox Developer Edition?

To top

Download from Mozilla Firefox Developer Edition webpage. Extract it with file-roller and move the folder to its final location. A good practice is to install it in /opt/ or /usr/local/.

Once you moved the files to their final location (say /opt/firefox_dev/), you can create the following file ~/.local/share/applications/firefox_dev.desktop to get a launcher with an icon distinct from normal Firefox.

[Desktop Entry]
Name=Firefox Developer 
GenericName=Firefox Developer Edition
Exec=/opt/firefox_dev/firefox %u
Terminal=false
Icon=/opt/firefox_dev/browser/chrome/icons/default/default128.png
Type=Application
Categories=Application;Network;X-Developer;
Comment=Firefox Developer Edition Web Browser.

To mark the launcher as trusted, make it executable:

chmod +x ~/.local/share/applications/firefox_dev.desktop

To launch it, navigate to ~/.local/share/applications/ using your “Files” application (ensure you turn on hidden folders), then double-click firefox_dev.desktop. Alternatively, search for Firefox Developer, and simply run the firefox binary, and voilà.

Note that, when you install manually, the F.D.E. does not have the unity global menu by default.

Set Up the SSL Certificate

To top

Run the certbot command like so, where example.com is your domain:

sudo certbot --apache -d example.com

If you want to install a single certificate that is valid for multiple domains pass the bare top-level domain name as first in the list, followed by any additional subdomains or aliases:

sudo certbot --apache -d example.com -d www.example.com

Install certificate in subdomain

sudo certbot --apache -d sub.sub2.domain.LTD
