You’re running the WP-CLI and get that message, plus the following error:
Error: One or more database tables are unavailable. The database may need to be repaired.
Try running the wp command like this:
HTTP_HOST=yoursitehostname.dom wp
Set the HTTP_HOST environment variable to whatever domain name was used to create the network, before you went multisite. Normally, this is “localhost”, but it might be something different.
I changed mine to “localhost.lo”, because I use the .lo fake domain on my LAN.
To save yourself having to type that long command, add the following to your .bashrc:
[code]
HTTP_HOST=yoursitehostname.dom
export HTTP_HOST
[/code]
Then:
. ~/.bashrc
Now wp should work.
Why Does This Work?
When PHP is called from the command line, all the environment variables are copied into $_SERVER.
Make a file, test.php, with this code to dump the $_SERVER variable:
<?php print_r($_SERVER);
Then run it like this:
php test.php
Instead of the usual $_SERVER variables, you will see your shell’s environment variables!
The –url Global Option and Multisite
If you need to target a specific site for your wp command, use the --url global option. If you have two sites: a.foo.com and b.foo.com, you can run your commands like this:
wp --url=a.foo.com
wp --url=b.foo.com
HTTP_HOST and Multisite
You can also use HTTP_HOST to set which site you’re affecting in your network.
HTTP_HOST=a.foo.com wp
HTTP_HOST=b.foo.com wp
