CentOS 8 how to run Peernet as service: Step-by-step

PeernetUser1

This step-by-step assumes that you already have a complied Peernet binary in the /root folder of your CentOS 8 installation.

Create custom systemd service

Navigate to /etc/systemd/system

[root@ ~] # cd /etc/systemd/system
[root@ system]#

Use editor of choice to create a new file called "peernet.service" (without quotes). In the following example, we are using nano.

[root@ system] # nano peernet.service

Copy/paste the following code in the newly created file.

[Unit]
Description=Peernet binary service
After=network.target

[Service]
WorkingDirectory=/root
ExecStart=/root/Peernet
Restart=always
RestartSec=5
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=%n

[Install]
WantedBy=multi-user.target

Exit nano, saving changes.

Ctrl + Z
Y

Check directory for file

[root@ system] # ls

Reload systemctl to make new file visible

[root@ system] # sudo systemctl daemon-reload

Enable peernet.service (you should see second line if successful).

[root@ system] # sudo systemctl enable peernet.service 
Created symlink /etc/systemd/multi-user.target.wants/peernet.service -> /etc/systemd/system/peernet.service

Start peernet.service

[root@ system] # sudo systemctl start peernet.service

Check status of peernet.service

[root@ system] # sudo systemctl status peernet.service

Invoking ./Peernet while peernet.service is running

In order to start a working instance of ./Peernet, first stop the peernet.service. Otherwise the system will try to run two instances concurrently. From /root:

[root@ ~] # sudo systemctl stop Peernet
[root@ ~] # ./Peernet
