Devstack服务

Question

I have installed ceilometer services in a devstack environnement by enabling them in local.conf"

enable_service ceilometer-acompute ceilometer-acentral ceilometer-anotification$
enable_service ceilometer-alarm-evaluator,ceilometer-alarm-notifier
enable_service ceilometer-api
enable_service ceilometer-aipmi

but I can not list the services when I do a rejoin-stack.sh and type Ctrl + a + " .

How I should resolve this problem, because I need to restart the ceilometer services as I am installing kwapi ?

Thank you in advance .

Answer 1

Ceilometer is middleware that is used by the other services. To "restart ceilometer" you should restart the entire stack with ./unstack.sh followed by ./stack.sh. If you want to uninstall and re-install, you could run ./clean.sh followed by ./stack.sh.

Answer 2

When you wanna restart services with devstack, have 2 main ways:

1. Run ./rejoin-stack.sh and press ctrl C + ctrl D to kill all services. Then re-run ./rejoin_stack.sh and press ctrl A + ctrl D for detaching. Then, all services were restarted.

2. Run "ps -ef | grep your_service_name" to find and kill the service that you need to restart. When you run above command, you will find the exact command to start that service. :D

But, I recommend you use the first way when restart any service with devstack. It is the best way to make your system run smoothy.

• First cd to folder devstack

  • You can find the file ./rejoin_stack.sh

  • Execute the same.

  • It will be executed and screen will be opened for access.

  • press ctrl + a + shift + "

  • Then it will be listing the running services

  • can move to service which needs to be stopped by scrolling towards it.

  • on the service which is needs to be stopped press enter

  • then press ctrl + c , it will stop the service

  • then press up arrow key to run the service again

  • service will be restarted successfully.
