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> cp  -p corosync.conf.example corosync.conf

shell> vim corosync.conf

totem {

       version: 2

       secauth: off

       threads: 0

       interface {

               ringnumber: 0

               bindnetaddr: 192.168.2.0

               mcastaddr: 226.94.1.1

               mcastport: 5405

       }

}

logging {

       fileline: off

       to_stderr: no

       to_logfile: yes

       to_syslog: yes

       logfile: /var/log/cluster/corosync.log

       debug: off

       timestamp: on

       logger_subsys {

               subsys: AMF

               debug: off

       }

}

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

crm(live)configure# property no-quorum-policy=ignore


四：测试
