This service is responsible for Cart Service in RobotShop e-commerce portal.
This service is written in NodeJS, Hence need to install NodeJS in the system.
# yum install nodejs make gcc-c++ -y
Let's now set up the cart application.
As part of operating system standards, we run all the applications and databases as a normal user but not with root user.
So to run the cart service we choose to run as a normal user and that user name should be more relevant to the project. Hence we will use roboshop as the username to run the service.
# useradd roboshop
So let's switch to the roboshop user and run the following commands.
$ curl -s -L -o /tmp/cart.zip "https://github.com/roboshop-devops-project/cart/archive/main.zip"
$ cd /home/roboshop
$ unzip /tmp/cart.zip
$ mv cart-main cart
$ cd cart
$ npm install
Now, lets set up the service with systemctl.
# mv /home/roboshop/cart/systemd.service /etc/systemd/system/cart.service
# systemctl daemon-reload
# systemctl start cart
# systemctl enable cart
