MongoDB

Petio supports two ways of connecting to a Mongo Database instance, locally or remote. We recommend the locally hosted MongoDB option.

MongoDB Locally

  • Configure the package management system (yum)

  • Create a /etc/yum.repos.d/mongodb-org-4.4.repo file so that you can install MongoDB directly using yum:

sudo nano /etc/yum.repos.d/mongodb-org-4.4.repo

  • Paste in the nano / terminal window:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

  • Press: "CTRL + O" to save and "CTRL+X" to exit.

  • To install the latest stable version of MongoDB, issue the following command:

sudo yum install -y mongodb-org

  • Start MongoDB:

sudo systemctl start mongod

  • Verify that MongoDB has started successfully:

sudo systemctl status mongod

  • To make sure MongoDB starts after restart use:

sudo systemctl enable mongod

MongoDB Locally - On A Different Host

By default, MongoDB doesn’t allow remote connections.

  • Locate your mongod.conf and edit it with your favorite editor. Include any local IP addresses you want to allow to connect to your MongoDB instance.

vim /etc/mongod.conf
# /etc/mongod.conf
# Listen to local and LAN interfaces.
bind_ip = 127.0.0.1,192.168.161.100

  • Restart the mongod service after making these changes

sudo systemctl restart mongod

If there is a firewall, you might need to use iptables to allow access to MongoDB. Example below:

  • Any connections can connect to MongoDB on port 27017

iptables -A INPUT -p tcp --dport 27017 -j ACCEPT

  • Only certain IPs can connect to MongoDB on port 27017

iptables -A INPUT -s <ip-address> -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -d <ip-address> -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT

MongoDB Remotely

  • Register for Atlas here.

  • Create a free cluster.

  • Change the provider or region if you need to. It may take some time to create the cluster.

  • After the cluster is made, click on connect and select MongoDB Compass and follow the instructions on screen.

Installing Petio

  • Create a user for Petio:

sudo useradd -M --shell=/bin/false petio

  • Make a directory for Petio:

sudo mkdir /opt/Petio

  • Download the latest version of Petio:

sudo wget https://petio.tv/releases/latest -O petio-latest.zip

  • Extract Petio to the directory we just made:

sudo unzip petio-latest.zip -d /opt/Petio

  • Change ownership of the directory for Petio:

sudo chown -R petio:petio /opt/Petio

  • Create the petio service with systemd:

sudo vi /etc/systemd/system/petio.service

[Unit]
Description=Petio a content request system
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=on-failure
RestartSec=1
ExecStart=/opt/Petio/bin/petio-linux
User=petio

[Install]
WantedBy=multi-user.target

  • Reload systemd:

sudo systemctl daemon-reload

  • Start Petio:

sudo systemctl start petio

Once you've completed theses steps, you can navigate to http://<hostname>:7777 to start configuring Petio.
