3 Agenda

4 Agenda Disclaimer Red Hat and Clustering Architecture Configure the Shared Storage (iscsi Target) Configure the Shared Storage (Raw Storage) Configure the Shared Storage (iscsi Initiator) Install web server software on both nodes

5 Agenda Install the clustering software on the nodes High Availability Resilient Storage Install the cluster management software on the management server High Availability Management Connect to the web management UI Define a Cluster Create Cluster Filesystem

6 Agenda Mount point clustered vs. persistent Define the fence device Assign hosts to fence device ports Define Failover Domains Define Resources For Clustered Web Service Define Clustered Web Service Test Clustered Web Service Test Failover

7 Disclaimer This presentation was developed on Red Hat Enterprise Linux 6.1 beta. You may see slight differences in the UI between now and 6.1 release. Then again, this presentation might burst into flames, too.

8 Red Hat and Clustering

9 Red Hat and Clustering Red Hat leads the way in Open Source clustering Acquired Sistina for $31 million in early 2004, including Global Filesystem and ClusterSuite. Made the code Open Source in mid Red Hat now offers Resilient Storage (clustered filesystem - GFS2) and High Availability (high availability application services) as layered products.

10 Architecture

11 Architecture Two node cluster neuromancer.tc.redhat.com and finn.tc.redhat.com each installed neuromancer finn

12 Architecture neuromancer and finn are managed by lady3jane.tc.redhat.com also installed neuromancer finn lady3jane (conga)

13 Architecture neuromancer and finn are iscsi initators connecting to molly.tc.redhat.com, an iscsi target neuromancer (initiator) finn (initiator) lady3jane (conga) molly (target)

14 Architecture Two examples will demonstrated today Apache web server cluster Cluster of virtual machines (time permitting)

15 Configure the Shared Storage (iscsi Target)

16 Configure the Shared Storage (iscsi Target) The machine which will be the target should be subscribed to the Red Hat Enterprise Linux Server (v. 6 for [arch]) on RHN or RHN Satellite

17

18 Configure the Shared Storage (iscsi Target) Install the Network Storage Server (storage-server) group using yum

19

20

21 Configure the Shared Storage (Raw Storage)

22 Configure the Shared Storage (Raw Storage) In this example, we'll use set up a logical volume on molly. fdisk pvcreate vgcreate lvcreate

23

24

25

26

27

28 Configure the Shared Storage (iscsi Target)

29 Configure the Shared Storage (iscsi Target) In this example, we'll set up molly as an iscsi target /etc/tgtd/targets.conf

30

31 Configure the Shared Storage (iscsi Target) chkconfig tgtd on service tgtd restart tgtadm --lld iscsi --mode target --op show

32

33

34 Configure the Shared Storage (iscsi Initiator)

35 Configure the Shared Storage (iscsi Initiator) Subscribe the server to the High Availability and Resilient Storage child channel for RHEL Server

36

37 Configure the Shared Storage (iscsi Initiator) Install the iscsi Storage Client group

38

39 Configure the Shared Storage (iscsi Initiator) chkconfig on and restart the iscsid (first) and iscsi services

40

41 Configure the Shared Storage (iscsi Initiator) Use iscsiadm to query the target (use the ip address, not the domain name)

42

43 Configure the Shared Storage (iscsi Initiator) Use iscsiadm to log in (use the ip address, not the domain name)

44

45 Configure the Shared Storage (iscsi Initiator) Verify there is a new block device available

46

47 Configure the Shared Storage (iscsi Initiator) Repeat these steps on the other node(s)

48

49 Configure the Shared Storage (iscsi Initiator) We'll create the filesystem later, after the cluster is defined

50 Install web server software on both nodes

51 Install web server software on both nodes yum groupinstall Web Server Verify httpd is chkconfig'd off (we'll let the cluster manage it), later Set the Listen address to the IP address we're going to run the clustered web server on (armitage.tc.redhat.com or )

52

53

54 Install the clustering software on the nodes

55 Install the clustering software on the nodes There are two components of the cluster High availability application service ( High Availability package group) Clustered filesystem (GFS2, or Resilient Storage package group)

56 Install the clustering software on the nodes Install the High Availability group first yum groupinstall High Availability

57

58 Install the clustering software on the nodes chkconfig ricci on passwd ricci service ricci start

59

60 Install the clustering software on the nodes Install the Resilient Storage package group next yum groupinstall Resilient Storage

61

62 Install the cluster management software on the management server

63 Install the cluster management software on the management server Install the High Availability Management package group yum groupinstall High Availability Management

64

65

66 Install the cluster management software on the management server chkconfig luci on service luci start Open the URL listed when luci starts (

67

68 Connect to the web management UI

69 Connect to the web management UI You will get an SSL warning, that's expected and normal

70

71

72

73 Define a Cluster

74 Define a Cluster In this case, two nodes neuromancer.tc.redhat.com finn.tc.redhat.com

75

76

77 Connect to the web management UI Note that when dealing with RHEL 6.1 clusters, the UI is asking for ricci's password, not root's!

78

79

80

81

82 Create Cluster Filesystem

83 Create Cluster Filesystem Now that the cluster is up, we can set up the shared storage from the hosts. Verify each node is using clustered logical volumes

84

85 Create Cluster Filesystem From a node: fdisk shared storage pvcreate vgcreate vgscan on all nodes vgdisplay to get extents lvcreate lvscan on all nodes mkfs.gfs2 make mount persistent (optional)

86 Create Cluster Filesystem Mount point clustered vs. persistent

87

88

89

90

91

92

93

94

95

96 Define the fence device

97 Define the fence device In this case, a WTI IPS-800 remote power switch

98

99

100

101 Assign hosts to fence device ports

102 Assign hosts to fence device ports Define the power port for each server

103

109 Define Failover Domains

110 Define Failover Domains prefer_neuromancer prefer_finn
