Yes. Most likely you don't even have to create the file
/etc/systemd/system/[email protected] at all, instead just symlink
it from /lib/systemd/system/[email protected], i.e. the common template.
Dan to give you an example which I used test to run multiple instances
of vsftpd of an template unit a while back with quick and dirty
directions I had noted down while doing it...
First here is a httpd template unit file for you to start fiddling with
and tailor to your needs since this is rather lengthy post but should
give you the general idea of what needs to be done and what Lennart is
referring to....
### Sample [email protected] template ###
[Unit]
Description=The Apache HTTP Server Instance %i
After=network.target
[Service]
Type=forking
PIDFile=/run/httpd/%i.pid
ExecStart=/usr/sbin/httpd -f /etc/httpd/conf.d/%i.conf -k start
ExecReload=/usr/sbin/httpd -t
ExecReload=/bin/kill -HUP $MAINPID
ExecStop=/usr/sbin/httpd -k stop
[Install]
WantedBy=multi-user.target
The VSFTPD template unit.
### [email protected] ###
[Unit]
Description=Vsftpd FTP Daemon Server Instance %i
After=network.target
[Service]
Type=forking
ExecStart=/usr/sbin/vsftpd /etc/vsftpd/%i.conf
[Install]
WantedBy=multi-user.target
Next create a multiple copy's of the vsftpd.conf file
for i in 1 2 3 4;do cp /etc/vsftpd/vsftpd.conf
/etc/vsftpd/vsftpd$i.conf; done
Set different log file for each of them...
for i in 1 2 3 4;do echo "xferlog_file=/var/log/vsftpd$i.log" >>
/etc/vsftpd/vsftpd$i.conf; done
Set different listening port in each configuration file on them...
for i in 1 2 3 4;do echo "listen_port=200$i" >>
/etc/vsftpd/vsftpd$i.conf; done
Then symbolic link that template to the name of the each configuration file
ln -s /lib/systemd/system/vsftpd\@.service
/etc/systemd/system/vsftpd\@vsftpd1.service
ln -s /lib/systemd/system/vsftpd\@.service
/etc/systemd/system/vsftpd\@vsftpd2.service
ln -s /lib/systemd/system/vsftpd\@.service
/etc/systemd/system/vsftpd\@vsftpd3.service
ln -s /lib/systemd/system/vsftpd\@.service
/etc/systemd/system/vsftpd\@vsftpd4.service
Reload the systemd daemon
systemctl daemon-reload
Start each instance
systemctl start [email protected] [email protected]
[email protected] [email protected]
Check to see if each instance is running and listening on different
ports...
[root@localhost system]# systemctl status [email protected]
