Creating a Linux server and log in to it using SSH

One of the benefits of the cloud is fast and easy creation of new severs on demand. This is how you quickly create a server and login to it.
First click on "Servers" in the menu to the left and then on "Create server".
When creating a new server we will first of all have to name it and chose a zone to create the server in. To reduce latency you want a zone that is close to the location where you the data to be served to.
For example if you have a website with mostly visitors from Sweden you don`t want to create a server in LA.
When the location is chosen we have to decide which operating system we want to use. For this example I will create an Ubuntu 16.04 server. Chose the Ubuntu 16.04 image in the list. If you have a snapshot or uploaded your own
image you can select it by changing the "Select boot source" option, for simplicity we will chose a public image.
If you want any specific packages installed to the server you can chose them from the packages in the next section. Since I want to create a web-server I will install a LAMP on it.
When choosing the size for the server you want a size that does not cost you to much but it will have to be able to run all the applications on the server. I know that my website is quite small with as far as no visitors so 1 GB of RAM and 1 Core will work great for me.
Im also happy with the volume size of 20 GB. The root partition can only be changed by stopping the server, creating a snapshot, and creating a new server. For this reason it is important to create a large enough root partition at start, unless you can plan for maintenance while increasing the partition at a later stage. A root partition can never be decreased in size.
Since I don`t have set up an own network or security group I will leave these as Default. I will however click the checkbox to Create an external IP for me, allowing me to ssh to the server when it`s created.
The last thing we will have to do is to chose a username and password to be able to login. If you have an SSH-key you want to use it`s possible to add that one as a Login keypair (See other guides on how to create it). I have one and will use it.
Be sure to use a strong password with at least 8 signs with small and capital letters, numbers and special signs.
When all this done click the "Create server" in the bottom right corner. After a short while your server will be created and you will see an IP adress you can connect to. Simply ssh to the machine as the user you chose.
