I used nodejs before, but I switched to go recently, I have no idea about managing the go process, is there anything like PM2 ?

Development Environment

For development, you'd probably need process manager that also monitor the file changes and live-reload your server binary.

I'm used to Godegansta's gin for such job for web server / api server development. There is also fresh, reflex and perhaps some others.

Production Environment

I'm using systemd to manage my Golang application process on Linux in production environment.

Define the Unit

This is my Unit File looks like this:

[Unit]
StopWhenUnneeded=true

[Install]
WantedBy=multi-user.target

[Service]
ExecStart=/usr/local/bin/<MY_GO_APP>
WorkingDirectory=/home/user/<MY_GO_APP_HOME_DIR>
User=<MY_GO_APP_USER>
Restart=always
RestartSec=5
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=%n

Create this file as /usr/lib/systemd/system/my_app.service (for Ubuntu), then run:

systemctl start my_app.service

would automatically start the service. As configured, systemd will always restart your process if it stopped.

Usual Operations

To have it always on when the machine starts:

systemctl enable my_app.service

If you change your unit file after the first start or enable, you need to run:

systemctl daemon-reload

To see the status of the process, run:

systemctl status my_app.service

To see the STDOUT of the process, run:

journalctl -f -u my_app.service
