VerneMQ
I have created a script to install vernemq on a raspberrypi The script also installs some important packages including erlang which is used by vernemq.
Just run the following command in your raspberrypi home folder:
time sh -c "$(curl -sSL https://raw.githubusercontent.com/suiluj/pi-adhoc-mqtt-cluster/master/install_scripts/vernemqinstall.txt)"
This procedure takes a lot of time. Because of the time at the beginning of the command you get the execution time after it has finished.
On a RaspberryPi Zero W it took 98m38.243s (about 1.5 hours).
The RaspberryPi 3 B+ took XX minutes (a lot faster than the raspberrypi zero).
This also depends on your internet connection speed. But most of the time takes the compiling of erlang.
sudo nano /etc/security/limits.conf
Add the following lines:
* soft nofile 65536
* hard nofile 65536
echo "export PATH=$PATH:/home/pi/vernemq/_build/rpi32/rel/vernemq/bin" >> ~/.bashrc
You have to exit and ssh login again to let it take effect.
vernemq start - start broker
vernemq stop - stop broker
vernemq console - start broker in console mode
q(). - close console
vernemq ping - echos pong when broker is running
Create a systemd service to autstart and restart vernemq:
sudo nano /etc/systemd/system/vernemq.service
[Unit]
Description=Runner for VerneMQ
After=network.target
[Service]
WorkingDirectory=/home/pi/vernemq/_build/rpi32/rel/vernemq/bin/
ExecStart=/home/pi/vernemq/_build/rpi32/rel/vernemq/bin/vernemq start
ExecStop=/home/pi/vernemq/_build/rpi32/rel/vernemq/bin/vernemq stop
User=pi
Type=forking
Restart=always
TimeoutSec=240
RestartSec=30
LimitNOFILE=300000
[Install]
WantedBy=multi-user.target
Afterwards run the following commands:
sudo systemctl daemon-reload
sudo systemctl enable vernemq.service
sudo systemctl start vernemq.service
Starting the vernemq broker takes a little time (especially on a pi zero) but there should be no errors.
You can check the status with sudo systemctl status vernemq
or with vernemq ping
