RabbitMQ management plugin issue

Question

I'm trying to install RabbitMQ management plugin but get the following in the console:

Error: {cannot_write_enabled_plugins_file,"/etc/rabbitmq/enabled_plugins",
           eacces}

I use Ubuntu 12. On this page is told that The management plugin is included in the RabbitMQ distribution. To enable it, use rabbitmq-plugins:

rabbitmq-plugins enable rabbitmq_management

but the result you see above

Answer 1

sudo rabbitmq-plugins enable rabbitmq_management?

P.S.: looks like a question for https://serverfault.com/

Answer 2

If you have provided 777 permissions to the file and still you are not able to enable it, try changing umask to 0022 for user

sudo chfn -o umask=0022 <username>

worked for me!
