RHCS创建高可用性群集Apache服务器

–>

系统版本：RHEL5.4

关闭SELinux，配置yum仓库，并配置各个服务器的环境

192.168.2.30 target.a.com 目标服务器

192.168.2.10 node1.a.com 节点1

192.168.2.20 node2.a.com 节点2

1> target server的配置

[[email protected] ~]# vim /etc/sysconfig/network

HOSTNAME=target.a.com

[[email protected] ~]# hostname target.a.com

[[email protected] ~]# vim /etc/hosts

[[email protected] ~]# yum install -y iscsi-initiator-utils ricci httpd

[[email protected] ~]# vim /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2011-10.com.a.node1

[[email protected] ~]# service iscsi start

[[email protected] ~]# chkconfig iscsi on

[[email protected] ~]# iscsiadm –mode discovery –type sendtargets –portal 192.168.2.30

[[email protected] ~]# iscsiadm –mode node –targetname iqn.2011-10.com.a.target:disk –portal 192.168.2.30 –login

[[email protected] ~]# echo“iscsiadm –mode discovery –type sendtargets –portal 192.168.2.30” >> /etc/rc.d/rc.local

[[email protected] ~]# echo “iscsiadm –mode node –targetname

iqn.2011-10.com.a.target:disk –portal 192.168.2.30 –login” >> /etc/rc.d/rc.local

[[email protected] ~]# service ricci start

[[email protected] ~]# chkconfig ricci on

3> initiator2的配置

[[email protected] ~]# vim /etc/sysconfig/network

HOSTNAME=node2.a.com

[[email protected] ~]# hostname node2.a.com

[[email protected] ~]# vim /etc/hosts

可以看到两个节点都成功接入target server，接下来开始做群集文件系统

1> 登录luci管理页，https://192.168.2.30:8084

在节点上创建群集文件系统GFS

[[email protected] ~]# mkdir /mnt/1

[[email protected] ~]# fdisk /dev/sdb

[[email protected] ~]# partprobe /dev/sdb //在两个initiator上都做该步骤

[[email protected] ~]# pvcreate /dev/sdb1

[[email protected] ~]# vgcreate vg01 /dev/sdb1

[[email protected] ~]# vgdisplay

[[email protected] ~]# service clvmd restart

[[email protected] ~]# lvcreate -L 3000M -n lv01 vg01

[[email protected] ~]# lvscan

[[email protected] ~]# lvdisplay

[[email protected] ~]# gfs_mkfs -p lock_dlm -t mycluster:lv01 -j 4 /dev/vg01/lv01

[[email protected] ~]# mount /dev/vg01/lv01 /mnt/1

在两个initiator上做完群集文件系统后，接着做以下步骤.

3> 点击“Submit”，点击“Fence”，创建Fence

在节点上添加fence

6> 创建Resources，点击“Add a Resource”

IP资源

服务脚本资源

节点1上监控日志
