you can search and replace text from within the vi text editor using the following command

:%s/0.0.0.0/localhost/

Beware, untested!

sed -ri .bak '/server.host:/s/: *"[^"]*"/: "localhost"/' /opt/kibana/config/kibana.yml

To test it run it without -i .bak and the change is output on stdout instead of changing the file. -i .bak causes in-place editing and the creation of a backup file.

it had worked this way: sudo sed -i -e '/server.host:/s/: *"[^"]*"/: "localhost"/' /opt/kibana/config/kibana.yml – Andrew Ramnikov Mar 16 '16 at 11:16
I picked the arguments for GNU sed. Apparently you're using a different one. – kamikaze Mar 16 '16 at 12:37
