Configure CentOS7

Configure Serial over LAN (SOL)

  • Edit grub settings /etc/default/grub
    ## Serial console settings
    GRUB_TERMINAL="serial console"
    GRUB_TERMINAL_OUTPUT="serial console"
    GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=1 --word=8 --parity=no --stop=1"
    
    GRUB_CMDLINE_LINUX:
    ## Remove: "rhgb quiet"
    ## Add: console=tty0 console=ttyS1,115200n8 vga=normal nomodeset 3
  • Rebuild the grub.cfg file with following command:
    grub2-mkconfig -o /boot/grub2/grub.cfg
  • Reboot.

Test SOL connection

  • SSH to iLO address.
  • Open SOL:
    textcons
  • To exit, press: <esc> <(>.

Configure networking (bonding, VLANs and bridges)

  • Set hostname:
    hostnamectl set-hostname <enter fqdn>
  • At the time of writing, there are some bugs in NetworkManager (nmcli) when enslaving VLAN devices into a bridge. So this configuration will not use NM.
  • Disable NM, enable network service:
    systemctl stop NetworkManager.service
    systemctl disable NetworkManager.service
    systemctl enable network.service
    systemctl start network.service
  • Create bond0 device:
    vi /etc/sysconfig/network-scripts/ifcfg-bond0
    DEVICE=bond0
    BOOTPROTO=none
    ONBOOT=yes
    USERCTL=no
    BONDING_OPTS="mode=4 miimon=100"
    NM_CONTROLLED=no
  • Add bond slaves:
    vi /etc/sysconfig/network-scripts/ifcfg-eno1
    DEVICE=eno1
    MASTER=bond0
    SLAVE=yes
    USERCTL=no
    ONBOOT=yes
    BOOTPROTO=none
    NM_CONTROLLED=no
    
    vi /etc/sysconfig/network-scripts/ifcfg-enp2s0f0
    DEVICE=enp2s0f0
    MASTER=bond0
    SLAVE=yes
    USERCTL=no
    ONBOOT=yes
    BOOTPROTO=none
    NM_CONTROLLED=no
    
    vi /etc/sysconfig/network-scripts/ifcfg-enp2s0f1
    DEVICE=enp2s0f1
    MASTER=bond0
    SLAVE=yes
    USERCTL=no
    ONBOOT=yes
    BOOTPROTO=none
    NM_CONTROLLED=no
    
    vi /etc/sysconfig/network-scripts/ifcfg-enp4s0
    DEVICE=enp4s0
    MASTER=bond0
    SLAVE=yes
    USERCTL=no
    ONBOOT=yes
    BOOTPROTO=none
    NM_CONTROLLED=no
  • Create VLAN and bridge devices, do this for every VLAN you have:
    vi /etc/sysconfig/network-scripts/ifcfg-br50
    DEVICE=br50
    ONBOOT=yes
    SLAVE=bond0.50
    TYPE=Bridge
    VLAN=yes
    NM_CONTROLLED=no
    
    vi /etc/sysconfig/network-scripts/ifcfg-bond0.50
    DEVICE=bond0.50
    VLAN=yes
    ONBOOT=yes
    USERCTL=no
    NM_CONTROLLED=no
    BRIDGE=br50
  • If needed, configure IP-addresses on bridge devices.
  • Restart networking:
    service network restart
  • Install tools:
    yum install bridge-utils tcpdump
  • Test:
    brctl show
    cat /proc/net/bonding/bond0
  • Configure DNS, edit networkscripts (DNS1, DNS2)

Configure firewall

  • If virbr0 isn't in zone internal, configure it so:
    firewall-cmd --permanent --zone=internal --change-interface=virbr0
  • Add local (sources) subnets to trusted zone:
    firewall-cmd --permanent --zone=trusted --add-source=192.168.2.0/24
  • Reload firewall:
    firewall-cmd --reload

Configure OS

  • Install and configure chrony
  • Install and configure apcupsd
  • Set tuned profile:
    tuned-adm profile virtual-host
  • Configure postfix

Install HP repository

  • Download add_repo script:
    curl -O http://downloads.linux.hp.com/add_repo.sh
  • Install wget:
    yum install wget
  • Run the script as root:
    sh ./add_repo.sh spp -d RHEL -r 7 -a x86_64
  • Install tools you need, e.g.:
    yum install hpssacli hp-health

Install virtualization tools

  • Install libvirt etc:
    yum groupinstall "Virtualization Host"
  • Enable guest service so that guests are suspended before reboot/shutdown and auto started after boot:
    systemctl enable libvirt-guests.service
