How to make a service start in SUSE Enterprise linux

By OK -
You have to add this file into desired runlevel. For example:
sudo update-rc.d my-service default
Will add it into default runlevel in Debian-based distros. Also, be sure that the file has such structure:
#!/bin/bash
case "$1" in
    start)
        #do startup commands
        ;;
    stop)
        #do stop commands
        ;;
 esac
However, in SUSE Linux there is /etc/init.d/skeleton that should be edited to create new scripts. This skeleton contains special comments (they are comments for the shell, but used by YaST) to describe on which runlevels the start/stop must be.
Once done, the script will show in YaST → System → System Services (runlevel) and can be switched on/off from there (making the links, etc).
To enable a service you can also use chkconfig, as in:
chkconfig --set someservice on
or
chkconfig --set someservice off
and the appropriate links will be created/deleted. For finer control over levels, you can use
chkconfig --level 35 someservice on

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availability ssh   ports:   protocols:   masquera
