1.安装集群组件

配置主从机yum源

[rhel-source]

name=Red Hat Enterprise Linux $releasever - $basearch - Source

baseurl=http://172.25.50.250/rhel6.5

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

 

[HighAvailability]

name=HighAvailability

baseurl=http://172.25.50.250/rhel6.5/HighAvailability

gpgcheck=0

[LoadBalancer]

name=LoadBalancer

baseurl=http://172.25.50.250/rhel6.5/LoadBalancer

gpgcheck=0

[ResilientStorage]

name=ResilientStorage

baseurl=http://172.25.50.250/rhel6.5/ResilientStorage

gpgcheck=0

[ScalableFileSystem]

name=ScalableFileSystem

baseurl=http://172.25.50.250/rhel6.5/ScalableFileSystem

gpgcheck=0

 

 

 

 

yum install luci ricci -y  ##在master机中安装组件

Yum install ricci -y ##在从机中安装ricci

Passwd ricci ##给ricci添加密码

 

 

2.管理集群

访问网页 https://172.25.50.1:8084

 

 

3.Fence

物理主机中

Yum install fence-virtd.x86_64 fence-virtd-libvirt.x86_64 -y

Yum install fence-virtd-multicast.x86_64 -y

 

fence_virtd -c

 

dd if=/dev/urandom of=/etc/cluster/fence_xvm.key bs=128 count=1

systemctl restart fence_virtd.service

scp /etc/cluster/fence_xvm.key root@172.25.50.1:/etc/cluster/

scp /etc/cluster/fence_xvm.key root@172.25.50.2:/etc/cluster/

访问 https://172.25.50.1:8084 添加fence

 

 

 

 

测试：

Fence_node server1 ##server立即跳电重启

 

4.Webfail

5.Resources

 

6.共享存储

Server3：

Yum isntall scsi-* -y

Vim /etc/tgt/targets.conf

<target iqn.2017-07.com.example:server.target1>

    backing-store /dev/vdb

    initiator-address 172.25.50.1

    initiator-address 172.25.50.2

</target>

     Tgt-admin -s ##查看状态

 /etc/init.d/tgtd start

Fdisk -l /dev/vdb

 

 

Server1 server2:

  安装iscsi

Yum install iscsi-* -y

  连接服务端硬盘

Iscsiadm -m discovery -t st -p 172.25.50.3

Iscsiadm -m node -l

  分区

Fdisk -cu /dev/sda

将sda分为lvm分区

Pvcreate /dev/sda1

Vgcreate clustervg /dev/sda1

Lvcreate -L +2G -n demo clustervg

Mkfs.gfs2 -j 3 -p dlm_lock -t MMM:mygfs2 /dev/clustervg/demo

Vim /etc/fstab

UUID="e959fbcd-563a-46ca-8e90-6ce7c72a2d74" /var/www/html gfs2  _netdev,defaults 0 0

gfs2_tool sb /dev/clustervg/demo all

Gfs2扩容

Lvextend -L +4G /dev/cluster/dome

Gfs2_grow /dev/cluster/dome
