安裝Cluster Stack依賴(lài):

# yum -y install clusterlib-devel corosynclib-devel

安裝Pacemaker可選依賴(lài):

# yum -y install ncurses-devel openssl-devel cluster-glue-libs-devel docbook-style-xsl

Pacemaker安裝:

# yum -y install pacemaker

crmsh安裝:

# wget -P /etc/yum.repos.d/ http://download./repositories/network:/ha-clustering/RedHat_RHEL-6/network:ha-clustering.repo
# yum -y install crmsh

時(shí)間同步配置

同步時(shí)間:

# ntpdate cn.pool.ntp.org

ntpd的配置添加時(shí)間服務(wù)器:

# vi /etc/ntp.conf
...
server cn.pool.ntp.org
...

修改:

# vi /etc/sysconfig/ntpd
...
OPTIONS="-u ntp:ntp -x -p /var/run/ntpd.pid -g"
...

啟動(dòng)ntpd:

# /etc/init.d/ntpd start
Starting ntpd:                                             [  OK  ]

添加自動(dòng)啟動(dòng)服務(wù):

# chkconfig --level 35 ntpd on

創(chuàng)建集群用的Authkey

運(yùn)行corosync-keygen生成authkey:

[root@P243 corosync]# cd /etc/corosync/
[root@P243 corosync]# corosync-keygen

開(kāi)另外一個(gè)Session窗口,運(yùn)行如下命令,加速key生成:

[root@P243 ~]# tar cvj / | md5sum > /dev/null

將生成的authkey拷貝到集群的其它主機(jī):

[root@P243 corosync]# scp authkey root@192.168.1.241:/etc/corosync/
[root@P243 corosync]# scp authkey root@192.168.1.242:/etc/corosync/

創(chuàng)建配置文件/etc/corosync/corosync.conf

               debug: off

將配置文件拷貝到其它主機(jī):

[root@P243 corosync]# scp corosync.conf root@192.168.1.241:/etc/corosync/
[root@P243 corosync]# scp corosync.conf root@192.168.1.242:/etc/corosync/

創(chuàng)建/etc/corosync/service.d/pacemaker

[root@P243 ~]# vi /etc/corosync/service.d/pacemaker
[root@P243 ~]# cat /etc/corosync/service.d/pacemaker

service {
      name: pacemaker
      ver: 1
}

將Pacemaker配置文件拷貝到其它主機(jī):

[root@P243 service.d]# cd /etc/corosync/service.d/
[root@P243 service.d]# scp pacemaker root@192.168.1.241:/etc/corosync/service.d/
[root@P243 service.d]# scp pacemaker root@192.168.1.242:/etc/corosync/service.d/

添加開(kāi)機(jī)自動(dòng)啟動(dòng)服務(wù)

# chkconfig --level 35 pacemaker on
# chkconfig --level 35 corosync on

啟動(dòng)Corosync

# service corosync start
Starting Corosync Cluster Engine (corosync):               [  OK  ]

檢查CoroSync是否運(yùn)行正確:

[root@P243 corosync]# corosync-objctl | grep members | grep ip
runtime.totem.pg.mrp.srp.members.-251549504.ip=r(0) ip(192.168.1.241) 
runtime.totem.pg.mrp.srp.members.-234772288.ip=r(0) ip(192.168.1.242) 
runtime.totem.pg.mrp.srp.members.-217995072.ip=r(0) ip(192.168.1.243) 

如果看不到上面類(lèi)似的結(jié)果,請(qǐng)確認(rèn)iptables規(guī)則設(shè)置正確.可以通過(guò)日志文件/var/log/cluster/corosync.log查看更多信息.

啟動(dòng)Pacemaker

三臺(tái)主機(jī)分別啟動(dòng)Pacemaker:

# service pacemaker start
Starting Pacemaker Cluster Manager:                        [  OK  ]
