When downloading Couchbase Server 2.1.1 Community Edition (the latest release at this time) for RHEL and CentOS from couchbase.com, the installation instructions simply state to "download the RPM and run rpm -i couchbase-server-enterprise_x86_64_2.1.1.rpm". However, this resulted in an error about missing libcrypto and other libraries on my off-the-shelf CentOS 6.4 server.

[Tapamishra](https://tapasmishra.wordpress.com/2013/05/03/how-to-install-couchbase-2-0-1-enterprise-server-on-centos-with-php-ext-couchbase/) provided some helpful hints:

1. First install the Development Tools group meta-package:  

   ```shell
   sudo yum -y groupinstall "Development Tools"
   ```

2. Second, install this older version of OpenSSL:  

   ```shell
   sudo yum -y install openssl098e
   ```

3. At this point, the RPM installation should succeed:  

   ```shell
   sudo rpm --install couchbase-server-community_x86_64_2.1.1.rpm
   ```

Remember to open port 8091 (if required) to continue setup using a web browser from another machine.
