Step 1: On an Existing Production Server in the Cluster

1. Login as root.
2. Stop all services.

   shell> systemctl stop glassfishd
   shell> systemctl stop mysqld
   shell> systemctl stop openldap

3. Create a folder in which to store all of the backup files.

   shell> mkdir /usr/local/backups

4. Make a backup of /etc/hosts.

   shell> cp /etc/hosts /usr/local/backups

5. Make a backup of all ifcfg network configuration files, except for ifcfg-lo.

   shell> cp /etc/sysconfig/network-scripts/ifcfg-* /usr/local/backups

6. If using firewalld, make a backup of the firewall configuration.

   shell> cp -r /etc/firewalld/zones/public.xml /usr/local/backups

7. Make a backup of the firewall rules.

   shell> firewall-cmd --list-all >> firewallrules

8. Make a backup of bashrc as well as all of the rc files it references at the bottom of the file, such as sakarc.

   shell> cp /etc/bashrc /usr/local/backups
   shell> cat /etc/bashrc
   shell> cp /etc/sakarc /usr/local/backups

9. Make a backup of the ssh config files.

   shell> cp /etc/ssh/ssh_config /etc/ssh/sshd_config /usr/local/backups

10. Make a backup of the service daemons.

    shell> cp /etc/init.d/glassfishd /etc/init.d/mysqld /usr/local/backups

    If using opendj, make a backup of opendjd.

    shell> cp -r /etc/init.d/opendjd /usr/local/backups

    If using openldap, make a backup of slapd.

    shell> cp -r /etc/systemd/system/multi-user.target.wants/slapd.service /usr/local/backups

11. Make a backup of my.cnf.

    shell> cp /etc/my.cnf /usr/local/backups

12. Make a backup of ldap configuration and database.

    shell> slapcat -n 0 -l /usr/local/strongauth/dbdumps/slapdbackup-<DATE>.conf
    
    shell> slapcat -n 2 -l /usr/local/strongauth/dbdumps/databackup-<DATE>.ldif

13. Make a backup of the strongauth folder in a zip file.

    shell> zip -r /usr/local/backups/strongauth.zip /usr/local/strongauth 

14. Make a backup of the saka folder in /usr/local/software in a zip file.

    shell> zip -r /usr/local/backups/saka.zip /usr/local/software/saka

15. Put the entire /usr/local/backups folder onto an external storage device (USB) to hold it.
