OpenNebula

Here is one systemd unit file I'm using for opennebula service:

[Unit]
Description=OpenNebula daemon
After=syslog.target network.target auditd.service

[Service]
Type=forking
User=oneadmin
Group=oneadmin
ExecStart=/usr/bin/one start
ExecStop=/usr/bin/one stop

[Install]
WantedBy=multi-user.target

Not sure if it fix the problem about oned starting before mysqld

I forgot, directories /var/run/one and /var/lock/one should be created by the rpm and owned by oneadmin.oneadmin, by specifing those directories in the %files section of the RPM spec file.
Without that the systemd unit I've provided should not work. CF http://fedoraproject.org/wiki/Packaging:Tmpfiles.d

best regards

here is my systemd unit files for opennebula with mysql/mariadb on CentOS 7 (fix problem with the opennebula sysvinit scripts where opennebula starts before mysql):

/lib/systemd/system/opennebula.service

[Unit]
Description=OpenNebula daemon
After=syslog.target network.target auditd.service mysqld.service

[Service]
Type=forking
User=oneadmin
Group=oneadmin
PermissionsStartOnly=true
ExecStartPre=-/usr/bin/mkdir /var/run/one
ExecStartPre=-/usr/bin/mkdir /var/lock/one
ExecStartPre=/usr/bin/chown -R oneadmin:oneadmin /var/run/one/
ExecStartPre=/usr/bin/chown -R oneadmin:oneadmin /var/lock/one/
ExecStart=/usr/bin/one start
ExecStop=/usr/bin/one stop

[Install]
WantedBy=multi-user.target

/lib/systemd/system/opennebula-sunstone.service

[Unit]
Description=OpenNebula daemon
After=syslog.target network.target auditd.service opennebula.service

[Service]
Type=forking
User=oneadmin
Group=oneadmin
ExecStart=/usr/bin/sunstone-server start-sunstone
ExecStop=/usr/bin/sunstone-server stop-sunstone

[Install]
WantedBy=multi-user.target

and /lib/systemd/system/opennebula-novnc.service

[Unit]
Description=OpenNebula daemon
After=syslog.target network.target auditd.service opennebula-sunstone.service

[Service]
Type=forking
User=oneadmin
Group=oneadmin
ExecStart=/usr/bin/novnc-server start
ExecStop=/usr/bin/novnc-server stop

[Install]
WantedBy=multi-user.target

Have to do oneflow and onegate service units but it's trivial.
