Set Up the Internet Repository: RHEL/CentOS

About this task

Before upgrading MapR, you need to set up or update a maprtech.repo file. Also, you need to install EPEL if you use the mapr-metrics server. The baseurl properties of the maprtech.repo specify the URLs of the packages you want to install. See the Release Notes for the URLs for all release packages.

Procedure

Change to the root user or use sudo.

Create a text file called maprtech.repo in the /etc/yum.repos.d/ directory with the following content, replacing <version> with the version of MapR that you want to install.

[maprtech]
name=MapR Technologies
baseurl=http://package.mapr.com/releases/v<version>/redhat/
enabled=1
gpgcheck=0
protect=1
                        
[maprecosystem]
name=MapR Technologies
baseurl=http://package.mapr.com/releases/ecosystem-5.x/redhat
enabled=1
gpgcheck=0
protect=1

If your connection to the Internet is through a proxy server, set the http_proxy environment variable before installation.
- Method 1:
```
http_proxy=http://<host>:<port>
export http_proxy
```
- Method 2: Set the value for the http_proxy environment variable by adding settings to the /etc/yum.conf file.
```
proxy=http://<host>:<port>
proxy_username=<username>
proxy_password=<password>
```

Download and install EPEL (Extra Packages for Enterprise Linux) if you use the mapr-metrics service; otherwise, skip this step.
