[Koha] ElasticSearch Shuts Down on Server Reboot [Was: Installing ElasticSearch]

Hello, all!

    It looks like my exuberance was premature. I spent much of yesterday
updating records. Towards the end of the day, I exported the entire
database -- both bibliographic and item records. Then I rebooted the
server. While the Koha interface came up, none of the titles I searched was
found. Instead, I got this error from the either Koha or the Linux box, to
wit:

*Software error:*

    I didn't lose my work from yesterday because I had a backup copy of the
authority and bibliographic files, and I had a backup copy of the previous
day's installation of Koha. I was prepared to upload the files into the
previous day's installation if I had to.

    However, by rebooting ElasticSearch manually, we could search again.
Must I reboot ElasticSearch everytime we reboot the server? How does one
get ElasticSearch to come up when the server is rebooted besides through
manual intervention? Surely, there must be an automatic way.

    Many thanks for everyone's help in this.
