name: unrecognized service under CentOS 6.5

[nifflin]

I use simplest example in README

https://github.com/takama/daemon#examples

After running the demo, I tried to stop this service with "service name stop", but returns error: "name: unrecognized service"

[takama]

Hi,
Did you use command service name start before?
service.Install() just create init.d script, nothing more.

[nifflin]

The same error info.

I compiled simplest demo, and run it. And I found the "name.conf" under /etc/init/. But "service name status" or "service name start" still not work.

[takama]

If your service has been installed in CentoOS 6, it has file /etc/init.d/<service name>.
Do you have that file?

[nifflin]

No. Only etc/init/ has name.conf file

[takama]

It means the service hasn't installed, possible cases:

1. Permission denied to installation of the service, please use sudo command to start this example.
2. Check file creation errors during execution of this example.

[nifflin]

"sudo" still the same. And, the example print error message if error happened, but the app only print service install success message.

[takama]

The call of service.Install() should create /etc/init.d/<service name> file or return error message. Please look at code snippets:

// Standard service path for systemV daemons
func (linux *systemVRecord) servicePath() string {
	return "/etc/init.d/" + linux.name
}

// Install the service
func (linux *systemVRecord) Install(args ...string) (string, error) {

	srvPath := linux.servicePath()

	file, err := os.Create(srvPath)
	if err != nil {
		return installAction + failed, err
	}
	defer file.Close()

[takama]

Some questions:

• Do you have /etc/init.d directory and some files into?
• Did you compile the binary on linux system?
• Could you send me result of the command strace -e trace=open <your executable file>?
  (If you don't have strace install it: yum install strace)

[nifflin]

1、YES
2、NO，on OS X with env GOOS=linux arch=amd64 go build main.go
3、Output of strace -e trace=open ./main

--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=28966, si_status=0, si_utime=0, si_stime=0} ---

Sorry, other command strace -e trace=stat,openat ./main or full output of strace ./main

[nifflin]

Should I move main file to "/usr/local/sbin/" before running it?

And, there is a /etc/init/ usage, is this right?

daemon/daemon_linux_upstart.go

Line 24 in 2d1aaa3

return "/etc/init/" + linux.name + ".conf"

Do you have upstart system installed on your VM?

[nifflin]

It's a physical machine. CentOS release 6.5 (Final). Text UI.
I am not sure whether upstart installed or not. Is initctl version the correct way to check it?
Output of initctl version
init (upstart 0.6.5)

[takama]

In this case you should use initctl start <job> or initctl stop <job> instead of service <name> start or service <name> stop.
Another advantage is using of second example with integrated commands install, start, stop, remove. You could use <your executable> install, <your executable> start, etc

[nifflin]

initctl start main works. But there are many .conf files under /etc/init.d, and almost all others services (like MySQL, iptables ...) can be managed by service start/stop/restart/status $SERVICE-NAME on this centos release. I think it's better to make service command working for my service.

If you need, I'd like to send you a temp CentOS 6.* vps account to check this issue.

[takama]

I see two solutions here:
Structural: adding possibility to prioritise of systems which installed from executable command line.
Quick: fork the daemon service, disable upstart module, recompile.

Can I close the ticket?

[nifflin]

OK, if I really need a library like this repo, I will fork a new version and try to fix it. Thank you.

I have created the new issue #50 with label enhancement
