• Storage setup for a standard file and print server:
  • Need two logical drives, RAID 1, 5 or 10
  • First logical drive is for /boot, swap and / partitions (recommend 50GB)
  • Second logical drive is for NSS pool (size accordingly)
• Installation options:
  • Local DVD install: Boot SLES 10 SP1 DVD and start a new install
  • Network install: Boot SLES 10 SP1 CD1 and use the following options:
    • hostip=xx.xx.xx.xx/24
    • gateway=xx.xx.xx.xx
    • nameserver=xx.xx.xx.xx
      
    • nfs://servername/install/SLES-10-SP2-DVD-x86_64-GM-DVD1.iso
  • To perform install remotely with VNC (DVD or network), add these options:
    • vnc=1
    • vncpassword=password
• Select Language, Accept License, select New Installation
• Set Clock and Time Zone info:
  • Set Hardware Clock Set To UTC
  • Region: USA, Time Zone: Pacific
  • Set Time and Date to current at your location (look at your watch)
• Click Partitioning:
  • Create Custom Partition Setup, Custom Partitioning (for experts)
  • You should have two logical drives available, sda and sdb:
    • Create 1GB primary partition on sda, format as ext2, mount as /boot
    • Create 2GB primary partition on sda, format as swap
    • Create a primary partition on sda, use remaining space, format as ext3, mount as /
    • sdb will hold the NSS pool, which will be configured after OES installation
• You can leave the defaults for software selection.
• Click Accept to start installation – Server will format partitions, install software, and reboot.

Staging Step 2 – Final Setup After Reboot:

• Enter password for root
• Enter hostname and domain (use lower case)
  • Uncheck Change Hostname via DHCP
• Network Configuration:
  • Click to Enable Firewall for SSH
    
  • Make sure VNC Remote Administration is enabled
  • Click Network Interfaces, Edit:
    • Add Name Servers
    • Add search domains
• Don’t check for Internet connectivity
• Accept defaults on CA Management and click Next
• Leave Authentication Method on Local, click Next
• Don’t create a local user, just click Next, and Yes that it’s OK
• Next on Release Notes
• Next on Hardware Configuration
• Uncheck Clone This System for Autoyast
• Base install is finished at this point. If you’re doing a VNC install, your installation session will die here. You can reconnect to the new server at this point if needed.

Staging Step 3 – Other Settings:

• If it is a normal file server, copy SLES and OES source ISO’s to server:
  • Create /install
  • Copy the following ISO’s to /install:
    • SLES-10-SP2-DVD-x86_64-GM-DVD1.iso
    • OES2-SP1-x86_64-CD1.iso
• Delete CD/DVD or network install source and add local source for SLES:
  • YaST: Software, Installation Source

• YaST: Network Services, NTP Configuration:
  • Change Automatically Start NTP Daemon to start During Boot
  • Go to Advanced Configuration
  • Add server ntp.doc.nv.gov and Enable for initial sync
• Configure and start SNMP:
  • Copy /etc/snmp/snmpd.conf from another server
  • Enter chkconfig snmpd on to set daemon to auto-start
  • Enter rcsnmpd start to start the daemon

• Enable Systat:

Setup for Backup Server:

• Configure forwarding of root’s email to GroupWise System Admin resource:
  echo user@test.com > /root/.forward
• Create/modify /etc/rsyncd.conf. See example Backup Server rsyncd.conf.
• Enable rsync daemon: chkconfig rsyncd on
• Start rsyncd: rcrsyncd start
• Change into the backup volume/directory:
  • For a NSS BACKUP volume: cd /media/nss/BACKUP
  • For a XFS /backup directory: cd /backup
• Create the backup folders for the primary server:
  mkdir primaryservername
  mkdir primaryservername/APPS
  mkdir primaryservername/backup
  mkdir primaryservername/boot
  mkdir primaryservername/etc
  mkdir primaryservername/GW
  mkdir primaryservername/mbr
  mkdir primaryservername/SHARED
  mkdir primaryservername/USERS
• Create the backup folders for the backup server:
  mkdir backupservername
  mkdir backupservername/backup
  mkdir backupservername/boot
  mkdir backupservername/etc
  mkdir backupservername/mbr
• Modify /etc/exports to export the BACKUP volume and /install directory:
  • /install *(ro,sync,root_squash) 10.1.1.0/255.255.255.0(rw,no_root_squash,sync) 10.1.2.0/255.255.255.0(rw,no_root_squash,sync)
  • For NSS BACKUP Volume:
    /media/nss/BACKUP primaryservername(rw,no_root_squash,sync,fsid=20) backup1(rw,no_root_squash,sync,fsid=20)
  • For XFS /backup directory:
    /backup primaryservername(rw,no_root_squash,sync) backup1(rw,no_root_squash,sync)
• Enable nfsserver: chkconfig nfsserver on
• Start nfsserver: rcnfsserver start
• Create backup script bkp_backupservername.sh. See example Backup Server Backup Script.
• Set executable permission: chmod +x bkp_backupservername.sh
• Create lst file. See example exclude.lst.
• Use crontab -e to edit the cron jobs and add the backup script:
  • For a NSS BACKUP volume: @daily /media/nss/BACKUP/bkp_backupservername.sh
  • For a XFS /backup directory: @daily /backup/bkp_backupservername.sh

Backup Setup for Primary Server:

• Configure forwarding of root’s email to GroupWise System Admin resource:
  echo user@test.com > /root/.forward
• Create the backup folder: mkdir /backup
• Change into backup folder: cd /backup
• Create the mount folder: mkdir primaryservername
• Modify /etc/fstab to auto-mount the backup volume:
  • NSS BACKUP volume:
    backupservername:/media/nss/BACKUP/primaryservername /backup/primaryservername nfs rw,intr,proto=tcp,rsize=32768,wsize=32768 0 0
  • XFS /backup directory:
    backupservername:/backup/primaryservername /backup/primaryservername nfs rw,intr,proto=tcp,rsize=32768,wsize=32768 0 0
• Mount the backup volume: mount -a
• Create backup script bkp_primaryservername.sh. See example Primary Server Backup Script.
• Set executable permission: chmod +x bkp_primaryservername.sh
• Create lst file. See example exclude.lst.
• Use crontab -e to edit the cron jobs and add:
  @daily /backup/bkp_primaryservername.sh

Example: Backup Server rsyncd.conf (NSS BACKUP volume):

uid = root
gid = root
read only = false
use chroot = true
transfer logging = false
log format = %h %o %f %l %b
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = primaryservername.test.com backup.test.com
slp refresh = 300

[primaryservername_APPS]

[primaryservername_boot]
path = /media/nss/BACKUP/primaryservername/boot

[primaryservername_etc]
path = /media/nss/BACKUP/primaryservername/etc

[primaryservername_GW]
path = /media/nss/BACKUP/primaryservername/GW

[primaryservername_USERS]
path = /media/nss/BACKUP/primaryservername/USERS

[primaryservername_SHARED]

uid = root
gid = root

use chroot = true
transfer logging = false
log format = %h %o %f %l %b
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = primaryservername.test.com backup1.test.com
slp refresh = 300

[primaryservername_APPS]
path = /backup/primaryservername/APPS

[primaryservername_boot]
path = /backup/primaryservername/boot

[primaryservername_etc]
path = /backup/primaryservername/etc

[primaryservername_GW]
path = /backup/primaryservername/GW

[primaryservername_USERS]
