Installing the Index Search Server in Cloud Mode
This mode of installation is explained in this section using an example. The following example installs the index search server in cloud mode with three Zookeeper nodes and two Solr nodes.
It is important that you install and configure the Zookeeper nodes first and then proceed with installing the index search server in high availability mode.

If you are installing index search server on Solaris platform, then you do not have option to install Zookeeper nodes using PSI. You need to perform post-installation configuration steps manually to set up and start Zookeeper nodes. For more information, see Setup and Start Zookeeper Nodes.
