What does the %i mean here, and why is it blank? (systemctl Centos7)

abefroman · 08-06-2017, 02:25 PM

Code:

# cat /usr/lib/systemd/system/clamd.service 
[Unit]
Description = clamd scanner (%i) daemon
After = syslog.target nss-lookup.target network.target

[Service]
Type = simple
ExecStart = /usr/sbin/clamd -c /etc/clamd.d/%i.conf --foreground=yes
Restart = on-failure
PrivateTmp = true

And in /var/log/messages I'm getting:

Code:

clamd: ERROR: Can't open/parse the config file /etc/clamd.d/.conf

The actual files is called /etc/clamd.d/scan.conf, although I could rename that if needed. If I rename it to just ".conf" it works, but clearly its suppose to be putting the %i variable there.

Code:

# mv scan.conf .conf
# service clamd start
Redirecting to /bin/systemctl start  clamd.service
# netstat -lntp |grep clamd
tcp        0      0 127.0.0.1:3310          0.0.0.0:*               LISTEN      28159/clamd

Thanks in advance!!!!

%i can be a denote for a data type to spit out info if valid.

as you see it again in

Code:

%i.config
// where it cound be like a wildcard but it is suppose to have a value to it. Because

where we look down here we see what for a filename ?

you will have to go find where %i is assinging the value to it and how it is getting same said value.

Code:

i = value

I'd read this and see if that is closer to what you need to know.

Likes a integer data type?

Is systemctl wanting a parameter?

Ex.

Code:

systemctl start clamd scan

%i is a specifier representing the instance name:

For instantiated units: this is the string between the "@" character and the suffix of the unit name.

See Specifiers section here:

Are you saying it should be:
/usr/lib/systemd/system/clamd@.service
instead of:
/usr/lib/systemd/system/clamd.service
?

And the config file clamd.conf instead of scan.conf ?

I'm no expert, I just came up with that info after a quick web search.

However I would have thought that the "between" would imply "and not including".
