Activate/deactivate modules¶
Rescuing a dysfunctional site from the Zotonic shell.
Why¶
Sometimes it happens that disabled or enabled a module by accident and your whole site is now dysfunctional. You can easily rescue your site, from the Erlang command line.
How¶
First launch the Zotonic EShell:
~/zotonic/bin/zotonic shell
On the Zotonic EShell: Deactivate a module:
z_module_manager:deactivate(mod_modulename, z:c(yoursitename)).
On the Zotonic EShell: Activate a module:
z_module_manager:activate(mod_modulename, z:c(yoursitename)).
On the Zotonic EShell: Restart a module:
z_module_manager:restart(mod_modulename, z:c(yoursitename)).
Where mod_modulename is the name of your module and yoursitename is the name of your site.
Check Your Hostname¶
If you can’t launch the shell chances are that your hostname is not a
fully-qualified domain name (FQDN). This complicates things since
Erlang is picky about allowing connections to unqualified nodes. For
example, the hostname should be myprimarysite.example.com
rather than
something random and local like coolserver
.
