Set of configurations to perform on the first run of your Raspbian Stretch Lite
After you had setup Raspbian Stretch Lite with SSH server enabled on your microSD card or setup Raspbian Stretch Lite with remote configuration over WiFi on first boot, there are a couple of configurations that you should perform for your Raspbian Stretch Lite.
This post walks through some of the configurations that you may want to perform on the first run of your Raspbian Stretch Lite.
Finding the IP address of the Raspberry Pi 3
When Raspbian Stretch Lite boots up, it will request an IP address from your router. This IP address is needed for you to SSH into the Raspberry Pi 3. Go to your router's address allocation table and find an entry with the name raspberrypi.
Alternatively, you can also use the ping command on your work computer to find the IP address of your Raspberry Pi 3:
Getting into the Raspbian Stretch Lite operating system via SSH
Let's suppose that the router allocated 192.168.1.109 to your Raspbian Stretch Lite.
In addition, the default credentials to log into Raspberry Pi Stretch Lite is as follows:
With the default credentials and the IP address that the router had given to Raspbian Stretch Lite, run the following command to SSH into the Raspbian Stretch Lite operating system:
Enter raspberry when Raspbian Stretch Lite prompts for password. This will result in Raspbian Stretch Lite greeting you with output similar to the following:
Linux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright. Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law. SSH is enabled and the default password for the 'pi' user has not been changed. This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.
Changing the default password
Since Raspbian Stretch Lite suggests that using the default password for the 'pi' user is a security risk, the next thing that you should do is to change the default password. To do so, enter the following command:
For the three prompts that follow the command, enter raspberry and your favourite password twice.
Configuring the locale settings
The next thing that you will want to do is to configure the locale settings for your Raspbian Stretch Lite. To do so, open up the Raspberry Pi Software Configuration Tool:
Once the Raspberry Pi Software Configuration tool had started, follow through the following screens to generate the "en_US.UTF-8" locale and set it as the default locale for the system environment:
After doing so, open up
sudo nano /etc/default/locale
And update the contents to look like the following:
LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 LANGUAGE=en_US.UTF-8
This will ensure that the locale settings for Raspbian Stretch Lite persist through system reboots.
The default timezone of Raspbian Stretch Lite is "Etc/UTC". However, if your Raspberry Pi 3 is not residing in that Timezone, you may want to change it.
For example, to change the Timezone on Raspbian Stretch Lite to Singapore's Timezone, you can use the Raspberry Pi Software Configuration Tool mentioned earlier and go through the following steps:
Once you had configured the Timezone, restart Raspbian Stretch Lite with the following command:
sudo shutdown -r now
Get back into Raspbian Stretch Lite with the following command once it had restarted successfully:
If you had arrived to this page without an idea on what to do with your Raspberry Pi, you may want to look at some of the projects that you can build on top of a Raspbian Stretch Lite operating system.
