Installing on RHEL

Install Couchbase Server on RHEL using the rpm command-line tool with the downloaded RPM package.

Important: RHEL6 and other newer Linux distributions running on physical hardware are known to have transparent hugepages feature enabled. While this can provide a measurable performance boost, under some conditions that Couchbase Server is known to trigger, this option may cause severe delays in page allocations. Therefore, it is strongly recommended to disable the transparent hugepages feature when installing Couchbase Server.


root-> rpm --install couchbase-server version.rpm

where version is the version number of the downloaded package.

After the rpm command completes, Couchbase Server starts automatically. It is configured to automatically start during boot under the 2, 3, 4, and 5 runlevels. Refer to the Red Hat RPM documentation for more information about installing packages using RPM.

After installation is completed, the installation process displays a message similar to the following:


Minimum RAM required : 4 GB 
    System RAM configured : 8174464 KB
    Minimum number of processors required :  4 cores 
    Number of processors on the system : 4 cores
