In order to be able to handle newer distros (fedora17+, ...) that uses
exclusively systemd, I need to fix how system services are handeled (start,
stop, restart, enable, disable, ...) (example: on fedora17+, /etc/init.d/gmond
doesn't exists. (it's /lib/systemd/system/gmond.service that is used)).
Instead of doing if else statement each time a service needs to be started or
enabled, I've seen that the base stuffs are already in place
(SystemService.pm). Unfortunately, it's not quite ready to support systemd, so
I need to fix things on the following components:
1/ OSCAR::OCA::OS_Detect (Added a service_mgt field: containing either systemd,
initscripts, manual).
Set it in the distro specific pm file. typically, debian is manual (start
scripts by calling /etc/init.d/service. redhat is initscripts (use the service
command), fedora15+ is "systemd" (systemctl used to enable, disable, start, ...)
2/ OSCAR::OCA::OS_Settings: will remove absolute path for the init script. will
keep only the name. Then we will read the os specific http_daemon and start it
using SystemService::
We should be able to avoid this in the future: (from ganglia opkg:
edit_ganglia_conf)
> # autoload apache in levels 345 and start it up
> my $HTTPD;
> for my $srv ("httpd", "apache2", "apache") {
> if (-x "/etc/init.d/$srv") {
> $HTTPD=$srv;
> last;
> }
> }
SystemServices.pm: Instead of gessing the right command to use based on sitro
packaging system, we use the os->{service_mgt} from OS_Detect::open. the we
clean up SystemServices.pm and now starting or restarting a service will be
usable.
Then use this code instead of checking -x /etc/init.d/daemon or blindly use
chkconfig wich fails on ubuntu as it's not mandatory for the system to have
/sbin/chkconfig installed.
Hopefully, it should be ok in a few days provided I don't find any code
elsewhere that can't be updated
