4.1corosync的安裝,兩臺都安裝上

## 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

compatibility: whitetank

totem {

version: 2

secauth:on?????????? 開啟身份驗證

threads: 0

interface {

ringnumber: 0

bindnetaddr: 172.16.0.0

mcastaddr: 226.94.1.1

mcastport: 5405

}

}

logging {

fileline: off

to_stderr: on

to_logfile: yes

#?????? to_syslog: yes

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

debug: off

timestamp: on

logger_subsys {

subsys: AMF

debug: off

}

}

amf {

mode: disabled

}

service {

ver:0

name:pacemaker

}

#corosync-keygen??????? 創建authkeys

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

兩臺mysql上分別創建用于日志的目錄

#mkdir /var/log/cluster

4.3通過mysql1開啟corosync，配置資源

1)開啟

#service corosync start

#ssh node2 'service corosync start'

#crm_mon

2)資源的配置

#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

*定義nfs資源，默認的超時時間是20s，是小于建議的時間60s的，所以手動配置

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
