4.1corosync的安装,两台都安装上

## yum install -y cluster-glue-1.0.6-1.6.el5.i386.rpm cluster-glue-libs-1.0.6-1.6.el5.i386.rpm corosynclib-1.2.7-1.1.el5.i386.rpm  corosync-1.2.7-1.1.el5.i386.rpm heartbeat-3.0.3-2.3.el5.i386.rpm heartbeat-libs-3.0.3-2.3.el5.i386.rpm libesmtp-1.0.4-5.el5.i386.rpm pacemaker-cts-1.1.5-1.1.el5.i386.rpm pacemaker-libs-1.1.5-1.1.el5.i386.rpm pacemaker-1.1.5-1.1.el5.i386.rpm perl-TimeDate-1.16-5.el5.noarch.rpm    resource-agents-1.0.4-1.1.el5.i386.rpm

4.2corosync的配置

#cd /etc/corosync

#cp corosync.conf.example corosync.conf

#vim corosync.conf

}

}

logging {

#corosync-keygen        创建authkeys

#scp authkeys corosync.conf node2:/etc/corosync

两台mysql上分别创建用于日志的目录

2)资源的配置

#crm

crm(live)#configure

crm(live)configure# primitive vip ocf:heartbeat:IPaddr params ip=172.16.99.1

crm(live)configure# primitive mysqld lsb:mysqld

crm(live)configure# primitive nfs ocf:heartbeat:Filesystem params device=172.16.98.3:/share directory=/data fstype=nfs op start timeout=60 op stop timeout=60

*定义nfs资源，默认的超时时间是20s，是小于建议的时间60s的，所以手动配置

crm(live)configure# colocation vip_mysqld_nfs inf: mysqld nfs vip

crm(live)configure# order mysqld_after_nfs inf: nfs mysqld

crm(live)configure# property stonith-enabled=false

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

crm(live)configure# verify

crm(live)configure# commit
