Guide to Creating and Managing Server in Linode (New Interface) – Part 2

In the previous post, you learned how to register an account and create server in Linode. Today we will continue to learn how to manage servers in Linode.

3. Server management in Linode

3.1. Dashboard – General Manager

Dashboard helps you manage the server overview. Here, you can see general parameters like IP Address, Plan, Region, OS and Backups.

By default, the server is created in the off state. To enable the server, click the top right icon and select Power On.

  • To access VPS via SSH Client, you use Bitvise, ZOC Terminal or PuTTy
  • To access directly using the Browser Console, click Launch

The Graph below shows a statistical graph of the status of VPS throught CPU, IO, IPv4 Network, and IPv6 Network parameters (within the past 24 hours).

3.2. Networking – IP, Network Manager

Networking tab is used to manage IPv4, IPv6, IP, DNS Resolver and Reverse DNS.

General information will appear in the Summary tab, including the current IPv4 and IPv6 lists of the server.

To add new IPv4 you click the Add an IP Address button, the price of the Linode is pretty cheap for only $1/month. To add IPv6 you need to contact support.

The IP in Linode allows you to configure Reverse DNS automatically, click the beside arrow and select Edit RDNS. After creating a new server you need to do this operation.

If you want to transfer IP from server A to server B and vice versa, please click on the IP Transfer tab.

IP Sharing helps you keep your IP address after deleting the server.

Finally, DNS Resolvers displays IPv4 Resolvers and IPv6 Resolvers server list.

3.3. Rebuild – Reinstall Server

To restore the server to its original state, you can reinstall the OS so that the server returns to its original state with the Rebuild tab.

Just re-select the OS operating system or leave it unchanged, then enter the password for the “root” account, press Rebuild to wait a few minutes.

Note: All data on the server will be deleted after rebuild, you should backup carefully before using this feature.

3.4. Resize

This is a great utility when using cloud server. In just a few clicks, you can upgrade your server to a higher plan for more RAM/CPU/bandwidth or choose a lower plan to lower the cost of ownership.

Select the desired plan, click the Resize button. Done!

3.5. Rescue

You use the Rescue tab to boot the server to Rescue mode or change the “root” account password.

3.6. Backups – Automatic backups

This is a paid feature of Linode, which automatically backs up daily data. Price will correspond to different plans.

The Linode backup method is the same as Ghost Windows, which will back up the entire server, including the operating system and data on it.

If you are not technically skilled, you can use this feature of Linode. Otherwise, use Rclone, automatically back up to the cloud completely free, more economical.

3.7. Settings – Resize hard drive and Swap, Alerts

This is the last tab in the server management page, which contains some general settings such as server name, alert when using Alerts resources. In particular, there is an important Advanced tab you need to know.

By default, the newly created server is set up with 512MB Swap, quite a few. You can completely increase the capacity of Swap in Linode, however this function is to be in the hard to see so not everyone knows.

To increase the capacity of the Swap, you need to reduce the hard drive space first to take space. For example, with the original 20GB VPS, you have 19.968MB of hard drive space and 512MB of Swap. You modify the hard drive space to 19.456MB to set up 1024MB Swap.

Add and subtract the corresponding numbers if you want to add more capacity for Swap.

4. Other tools

4.1. LongView – System monitoring tool

LongView is a great server monitoring tool dedicated to Limode VPSs. The tool helps to keep track of all important system data such as CPU, Memory, Network, as well as aggregate and detail statistics for each process. In addition, the tool provides real-time statistical graph that helps you quickly identify problems of system.

LongView works consistently on Linux operating systems:

  • CentOS 5, 6, and 7
  • Ubuntu 10.04, 12.04, 14.04 and 16.04
  • Fedora 17, 18, and 19
  • Debian 6, 7, and 8

The installation of LongView is quite simple. You can also install LongView on other Linux VPS besides Linode VPS.

You only need to access the menu LongView (not in the new interface so I used the old interface link), select Add Client.

The wizard screen appears with the Longview Agent installation command. Copy and run the command on the SSH Terminal window. Example:

Thus, you have successfully installed. Minutes later, the parameters will be statistically displayed.

Note: To display Real-time parameters, you need to configure stub_status for Nginx.

5. Summary
