Installing Echo Storm on RHEL Systems: A Step-by-Step Guide

Echo Storm instaling 'Echo Storm instaling' is a crucial process that requires attention to detail, especially when it comes to setting up repositories on Red Hat Enterprise Linux (RHEL) systems. In this article, we will walk you through the necessary steps to install Echo Storm on RHEL 7.x systems.

Before we begin, it's essential to note that these steps are only applicable to RHEL 7.x systems and can be ignored on CentOS 7.x distributions. On CentOS systems, the relevant repository is typically enabled by default, whereas on RHEL systems, you need to enable the `rhel-7-server-optional-rpms` repository.

To start with, you need to ensure that the necessary packages are installed. Specifically, you require the `python3-devel` package, which will be automatically installed during the installation of the `st2` package if it's available in an enabled repository. However, as StackStorm uses Python 3 and requires the `python3-devel` package, you need to make sure that the default Python version on your system is Python 3.

Once you've confirmed that your system meets these requirements, proceed with enabling the necessary services using the following commands:

```

sudo systemctl enable mongod rabbitmq-server redis

sudo systemctl start mongod rabbitmq-server redis

```

Next, you need to create a repository for MongoDB. To do this, run the following command:

```

sudo sh -c 'cat /etc/yum.repos.d/mongodb-org-4.repo' \

name=MongoDB Repository \

baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/ \

gpgcheck=1 \

enabled=1 \

gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc EOT

```

This command will add the key and repository for the latest stable MongoDB version (4.0).

Finally, you're ready to install WebUI and set up SSL termination. This is a crucial step in securing your Echo Storm installation.

In conclusion, installing Echo Storm on RHEL systems requires careful attention to detail, especially when it comes to setting up repositories. By following these steps, you'll be able to successfully install Echo Storm and ensure that your system meets the necessary requirements for optimal performance.
