大纲
一、环境准备
二、拓扑准备
三、安装与配置heartbrat
四、配置NFS服务
五、安装与配置MySQL
六、crm配置资源
一、环境准备
1.操作系统
CentOS 5.5 X86_64 位系统
2.软件环境
heartbeat-2.1.4-11.el5
heartbeat-gui-2.1.4-11.el5
mysql-5.5.33(注：这里用的mysql版本是通用二进制包，直接解压就能用的，若有博友对mysql安装有问题，请参考： )
3.高可用集群使用条件
(1).节点名称必须跟 uname -n 命令的执行结果一致
node1:
[root@node1 src]# uname -n
node1.test.com
[root@node1 src]# vim /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.18.201 node1.test.com node1
192.168.18.202 node2.test.com node2
node2:
[root@node2 ~]# uname -n
node2.test.com
[root@node2 ~]# vim /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.18.201 node1.test.com node1
192.168.18.202 node2.test.com node2
(2).各节点之间ssh互信
node1:
ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''
ssh-copy-id -i .ssh/id_rsa.pub root@node2.test.com
node2:
ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''
ssh-copy-id -i .ssh/id_rsa.pub root@node2.test.com
(3).各节点之间时间同步
node1:
[root@node1 ~]# ntpdate 202.120.2.101
node2:
[root@node2 ~]# ntpdate 202.120.2.101
4.增加EPEL yum源
node1,node2:
[root@node src]# wget Fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
[root@node src]# rpm -ivh epel-release-5-4.noarch.rpm
warning: epel-release-5-4.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
Preparing... ########################################### [100%]
1:epel-release ########################################### [100%]
[root@node src]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
[root@node src]# yum list
5.关闭防火墙与SELinux
node1,node2:
[root@node ~]# service iptables stop
[root@node ~]# vim /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
二、拓扑准备
说明：拓扑与前面几篇（见下面链接）一致，这里就不详细说明了。
