### Steps to install OpenProject on CentOS 7 All steps are run with `sudo` to execute as the root user. **1. Import the packager.io repository signing key** Import the PGP key used to sign our packages. Since we're using the _packager.io_ platform to distribute our packages, both package source and signing key are tied to their service. ```bash sudo rpm --import https://rpm.packager.io/key ``` **2. Add the OpenProject package source** Create the file `/etc/yum.repos.d/openproject.repo` with the following contents ``` [openproject] name=Repository for opf/openproject-ce application. baseurl=https://rpm.packager.io/gh/opf/openproject-ce/centos7/stable/6 enabled=1 ``` **3. Install the OpenProject Community Edition package** Using the following command, yum will install the package and all required dependencies. ```bash sudo yum install openproject ```
