一:IP地址hosts文件以及主机名配置
修改主机名和hosts文件
server1：
shell>hostname server1.gz.com
shell>vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server1.gz.com
shell>vim /etc/hosts
192.168.2.10 server1.gz.com
192.168.2.20 server2.gz.com
server2:
shell>hostname server2.gz.com
shell>vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server2.gz.com
shell>vim /etc/hosts
192.168.2.10 server1.gz.com
192.168.2.20 server2.gz.com
二:软件安装
在根目录下新建一个corosync文件夹，将软件包全部上传到此文件夹下。
shell>cd /corosync
shell>yum localinstall *rpm --nogpgcheck
三：配置corosync
shell>cd /etc/corsync

shell> mkdir /var/log/cluster/ #新建群集日志目录
shell> corosync-keygen
shell> service corosync start
检查错误以及查看启动过程
shell>grep -i -e "corosync cluster engine" -e "configuration file" /var/log/messages
shell>grep -i totem /var/log/messages
shell>grep -i error /var/log/messages
shell>grep -i pcmk_startup /var/log/messages
安装服务
shell>yum install httpd
定义资源服务
shell>crm
crm(live)configure# primitive webip ocf:heartbeat:IPaddr params ip=192.168.2.100
crm(live)configure# property stonith-enabled=false
crm(live)configure# group webgroup webip webserver
