Installing Bazel on Fedora and CentOS

The Bazel team does not provide official packages for Fedora and CentOS. Vincent Batts (@vbatts) generously maintains unofficial packages on Fedora COPR.

The commands below must be run either via sudo or while logged in as root.

Add --allowerasing when installing an upgrade from a previous major version of the Bazel package.

Installing on Fedora 25+

The DNF package manager can install Bazel from the COPR repository. Install the copr plugin for DNF if you have not already done so.
```
 dnf install dnf-plugins-core
```
Run the following commands to add the Bazel repository and install the package:
```
 dnf copr enable vbatts/bazel
 dnf install bazel3
```

Installing on CentOS 7

Download the corresponding .repo file from Fedora COPR and copy it to /etc/yum.repos.d/.
Run the following command:
```
 yum install bazel3
```
