[2] | Stop and turn OFF auto-start setting for a service if you don'd need it. (it's iscsi as an example below) |
dlp:~ # systemctl stop iscsi dlp:~ # systemctl disable iscsi |
[3] | There are some SysV services yet. Those are controled by chkconfig like follows. |
dlp:~ # chkconfig --list Note: This output shows SysV services only and does not include native systemd services. SysV configuration data might be overridden by native systemd configuration. If you want to list systemd services use 'systemctl list-unit-files'. To see services enabled on particular target use 'systemctl list-dependencies [target]'. after.local 0:off 1:off 2:off 3:off 4:off 5:off 6:off cifs 0:off 1:off 2:off 3:off 4:off 5:off 6:off dbus 0:off 1:off 2:on 3:on 4:off 5:on 6:off inputattach 0:off 1:off 2:off 3:off 4:off 5:off 6:off ipmi 0:off 1:off 2:off 3:off 4:off 5:off 6:off nfs 0:off 1:off 2:off 3:off 4:off 5:off 6:off ..... ..... # for exmaple, turn OFF auto-start setting for snmpd dlp:~ # chkconfig snmpd off |
