一、pacemaker 是什么
1.pacemaker 简单说明
  pacemaker(直译:心脏起搏器),是一个群集资源管理器。它实现最大可用性群集服务(亦称资源管理)的节点和资源级故障检测和恢复使用您的首选集群基础设施(OpenAIS的或Heaerbeat)提供的消息和成员能力。
  它可以做乎任何规模的集群,并配备了一个强大的依赖模型,使管理员能够准确地表达群集资源之间的关系(包括顺序和位置)。几乎任何可以编写脚本,可以管理作为心脏起搏器集群的一部分。
  我再次说明一下,pacemaker是个资源管理器,不是提供心跳信息的,因为它似乎是一个普遍的误解,也是值得的。pacemaker是一个延续的CRM(亦称Heartbeat V2资源管理器),最初是为心跳,但已经成为独立的项目。
2.pacemaker 由来
  大家都知道,Heartbeat 到了V3版本后,拆分为多个项目,其中pacemaker就是拆分出来的资源管理器。

[*]  Heartbeat 3.0拆分之后的组成部分:
[*]  Heartbeat:将原来的消息通信层独立为heartbeat项目,新的heartbeat只负责维护集群各节点的信息以及它们之前通信;
[*]  Cluster Glue:相当于一个中间层,它用来将heartbeat和pacemaker关联起来,主要包含2个部分,即为LRM和STONITH。
[*]  Resource Agent:用来控制服务启停,监控服务状态的脚本集合,这些脚本将被LRM调用从而实现各种资源启动、停止、监控等等。
[*]  Pacemaker : 也就是Cluster Resource Manager (简称CRM),用来管理整个HA的控制中心,客户端通过pacemaker来配置管理监控整个集群。
二、pacemaker 特点

[*]  主机和应用程序级别的故障检测和恢复
[*]  几乎支持任何冗余配置
[*]  同时支持多种集群配置模式
[*]  配置策略处理法定人数损失(多台机器失败时)
[*]  支持应用启动/关机顺序
[*]  支持,必须/必须在同一台机器上运行的应用程序
[*]  支持多种模式的应用程序(如主/从)
[*]  可以测试任何故障或群集的群集状态
三、pacemaker 内部结构

1.群集组件说明:

[*]  stonithd:心跳系统。
[*]  lrmd:本地资源管理守护进程。它提供了一个通用的接口支持的资源类型。直接调用资源代理(脚本)。
[*]  pengine:政策引擎。根据当前状态和配置集群计算的下一个状态。产生一个过渡图,包含行动和依赖关系的列表。
[*]  CIB:群集信息库。包含所有群集选项,节点,资源,他们彼此之间的关系和现状的定义。同步更新到所有群集节点。
[*]  CRMD:集群资源管理守护进程。主要是消息代理的PEngine和LRM,还选举一个领导者(DC)统筹活动(包括启动/停止资源)的集群。
[*]  OpenAIS:OpenAIS的消息和成员层。
[*]  Heartbeat:心跳消息层,OpenAIS的一种替代。
[*]  CCM:共识群集成员,心跳成员层。
[*]  CMAN是红帽RHCS套件的核心部分,CCS是CMAN集群配置系统,配置cluster.conf,而cluster.conf其实就是openais的配置文件,通过CCS映射到openais。
2.功能概述   
  CIB使用XML表示集群的集群中的所有资源的配置和当前状态。CIB的内容会被自动在整个集群中同步,使用PEngine计算集群的理想状态,生成指令列表,然后输送到DC(指定协调员)。Pacemaker 集群中所有节点选举的DC节点作为主决策节点。如果当选DC节点宕机,它会在所有的节点上, 迅速建立一个新的DC。DC将PEngine生成的策略,传递给其他节点上的LRMd(本地资源管理守护程序)或CRMD通过集群消息传递基础结构。当集群中有节点宕机,PEngine重新计算的理想策略。在某些情况下,可能有必要关闭节点,以保护共享数据或完整的资源回收。为此,Pacemaker配备了stonithd设备。STONITH可以将其它节点“爆头”,通常是实现与远程电源开关。Pacemaker会将STONITH设备,配置为资源保存在CIB中,使他们可以更容易地监测资源失败或宕机。
四、centos6.x+pacemaker+corosync实现zabbix高可用
1、环境说明
  OS:Centos 6.7 x86_64mini
  APP:Pacemaker 1.1.15
  LNMP+Zabbix 3.4.1
  corosync+pcs+cman
  IP ADDR:vip-192.168.8.47/20
  zabbix01-192.168.8.61/20
  zabbix02-192.168.8.63/20
  zabbixdb-192.168.8.120/20
  PS:IP地址需要根据个人具体环境配置,VIP和zabbix要在同一网段。
  拓扑结构

  PS:接下来会直接介绍pacemaker和corosync的安装和配置,关于zabbix+LNMP环境的部分请参考之前发表的“zabbix3.2编译安装”或“zabbix高可用”两篇文章。
五、安装pacemaker和corosync(各个节点均要运行)
1、前提条件各个节点完成主机解析工作。
  vim /etc/hosts
  # cat /etc/hosts
  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  192.168.8.61 zabbix01.okooo.cn zabbix01
  192.168.8.63 zabbix02.okooo.cn zabbix02
  192.168.8.120 zbxdb.okooo.cn zbxdb
2、各个节点的时间同步
  ntpdate 210.72.145.44
3、各个节点完成互信工作
  ssh-keygen-t rsa -f ~/.ssh/id_rsa-P ''
  ssh-copy-id -i .ssh/id_rsa.pub root@zabbix01/02/db.okooo.cn
4、关闭防火墙与SELinux
  # cat /etc/selinux/config
  # This file controls the state of SELinux on the system.
  # SELINUX= can take one of these three values:
  #       enforcing - SELinux security policy is enforced.
  #       permissive - SELinux prints warnings instead of enforcing.
  #       disabled - SELinux is fully disabled.
  SELINUX=disabled
  # SELINUXTYPE= type of policy in use. Possible values are:
  #       targeted - Only targeted network daemons are protected.
  #       strict - Full SELinux protection.
  SELINUXTYPE=targeted
  # /etc/init.d/iptables status
  iptables: Firewall is not running.
5、安装pacemaker+corosync+pcs
  yum install -y pacemaker corosync pcs
六、配置corosync
1、设置变量
  export ais_port=4000
  export ais_mcast=226.94.1.1
  export ais_addr=192.168.15.0
  env|grep ais
2、更改corosync配置文件
  cp /etc/corosync/corosync.conf.example /etc/corosync/corosync.conf
  sed -i.bak“s /.* mcastaddr:。* / mcastaddr:\ $ ais_mcast / g”/etc/corosync/corosync.conf
  sed -i.bak“s /.* mcastport:。* / mcastport:\ $ ais_port / g”/etc/corosync/corosync.conf
  sed -i.bak“s /.* bindnetaddr:。* / bindnetaddr:\ $ ais_addr / g”/etc/corosync/corosync.confcat /etc/corosync/corosync.conf
# Please read the corosync.conf.5 manual pagecompatibility: whitetanktotem {   version: 2      secauth: on #启动认证      threads: 2      interface {          ringnumber: 0          bindnetaddr: 192.168.15.0 #修改心跳线网段          mcastaddr: 226.94.1.1 #组播传播心跳信息          mcastport: 4000          ttl: 1      }}logging {   fileline: off      to_stderr: no      to_logfile: yes      to_syslog: no      logfile: /var/log/cluster/corosync.log #日志位置      debug: off      timestamp: on      logger_subsys {          subsys: AMF          debug: off      }}amf {   mode: disabled}#启用pacemakerservice {   ver: 0      name: pacemaker}aisexec {   user: root      group: root}注:用 man corosync.conf 可以查看所有选项的意思。3.生成密钥文件
注:corosync生成key文件会默认调用/dev/random随机数设备,一旦系统中断的IRQS的随机数不够用,将会产生大量的等待时间,因此,为了节约时间,我们在生成key之前讲random替换成urandom,以便节约时间。mv /dev/{random,random.bak} ln -s /dev/urandom /dev/randomcorosync-keygenPS:以上步骤要在所有节点上运行。七、安装和配置cman
  yum install -y cman
  sed -i.sed "s/.*CMAN_QUORUM_TIMEOUT=.*/CMAN_QUORUM_TIMEOUT=0/g" /etc/sysconfig/cman
  # cat /etc/sysconfig/cman
  # CMAN_CLUSTER_TIMEOUT -- amount of time to wait to join a cluster
  # before giving up. If CMAN_CLUSTER_TIMEOUT is positive, then we will
  # wait CMAN_CLUSTER_TIMEOUT seconds before giving up and failing if
  # we can't join a cluster. If CMAN_CLUSTER_TIMEOUT is zero, then we
  # will wait indefinitely for a cluster join. If CMAN_CLUSTER_TIMEOUT is
  # negative, do not check to see if we have joined a cluster.
  #CMAN_CLUSTER_TIMEOUT=5# CMAN_QUORUM_TIMEOUT -- amount of time to wait for a quorate cluster on
  # startup. Quorum is needed by many other applications, so we may as
  # well wait here. If CMAN_QUORUM_TIMEOUT is zero, quorum will
  # be ignored.
  CMAN_QUORUM_TIMEOUT=0# CMAN_SHUTDOWN_TIMEOUT -- amount of time to wait for cman to become a
  # cluster member before calling 'cman_tool' leave during shutdown.
  # The default is 60 seconds
  #CMAN_SHUTDOWN_TIMEOUT=6# CMAN_NOTIFYD_START - control the startup behaviour for cmannotifyd,
  # the variable can take 3 values:
  # yes | will always start cmannotifyd
  # no | will never start cmannotifyd
  # conditional (default) | will start cmannotifyd only if scriptlets
  # are found in /etc/cluster/cman-notify.d
  #CMAN_NOTIFYD_START=conditional# CMAN_SSHD_START -- control sshd startup behaviour,
  # the variable can take 2 values:
  # yes | cman will start sshd as early as possible
  # no (default) | cman will not start sshd
  #CMAN_SSHD_START=no# DLM_CONTROLD_OPTS -- allow extra options to be passed to dlm_controld daemon.
  #DLM_CONTROLD_OPTS=""# Allow tuning of DLM kernel config.
  # do NOT change unless instructed to do so.
  #DLM_LKBTBL_SIZE=""
  #DLM_RSBTBL_SIZE=""
  #DLM_DIRTBL_SIZE=""
  #DLM_TCP_PORT=""# FENCE_JOIN_TIMEOUT -- seconds to wait for fence domain join to
  # complete. If the join hasn't completed in this time, fence_tool join
  # exits with an error, and this script exits with an error. To wait
  # indefinitely set the value to -1.
  #FENCE_JOIN_TIMEOUT=20# FENCED_MEMBER_DELAY -- amount of time to delay fence_tool join to allow
  # all nodes in cluster.conf to become cluster members. In seconds.
  #FENCED_MEMBER_DELAY=45# FENCE_JOIN -- boolean value used to control whether or not this node
  # should join the fence domain. If FENCE_JOIN is set to "no", then
  # the script will not attempt to the fence domain. If FENCE_JOIN is
  # set to "yes", then the script will attempt to join the fence domain.
  # If FENCE_JOIN is set to any other value, the default behavior is
  # to join the fence domain (equivalent to "yes").
  # When setting FENCE_JOIN to "no", it is important to also set
  # DLM_CONTROLD_OPTS="-f0" (at least) for correct operation.
  # Please note that clusters without fencing are not
  # supported by Red Hat except for MRG installations.
  #FENCE_JOIN="yes"# FENCED_OPTS -- allow extra options to be passed to fence daemon.
  #FENCED_OPTS=""# NETWORK_BRIDGE_SCRIPT -- script to use for xen network bridging.
  # This script must exist in the /etc/xen/scripts directory.
  # The default script is "network-bridge".
  #NETWORK_BRIDGE_SCRIPT="network-bridge"# CLUSTERNAME -- override clustername as specified in cluster.conf
  #CLUSTERNAME=""# NODENAME -- specify the nodename of this node. Default autodetected.
  #NODENAME=""# CONFIG_LOADER -- select default config parser.
  # This can be:
  # xmlconfig - read directly from cluster.conf and use ricci as default
  # config propagation method. (default)
  #CONFIG_LOADER=xmlconfig# CONFIG_VALIDATION -- select default config validation behaviour.
  # This can be:
  # FAIL - Use a very strict checking. The config will not be loaded if there
  # are any kind of warnings/errors
  # WARN - Same as FAIL, but will allow the config to load (this is temporarily
  # the default behaviour)
  # NONE - Disable config validation. Highly discouraged
  #CONFIG_VALIDATION=WARN# CMAN_LEAVE_OPTS -- allows extra options to be passed to cman_tool when leave
  # operation is performed.
  #CMAN_LEAVE_OPTS=""# INITLOGLEVEL -- select how verbose the init script should be.
  # Possible values:
  # quiet - only one line notification for start/stop operations
  # terse (default) - show only required activity
  # full - show everything
  #INITLOGLEVEL=terse
八、编辑cluster.conf   
vim /etc/cluster/cluster.conf # cat /etc/cluster/cluster.conf  <?xml version="1.0"?>
  <cluster config_version="1" name="zabbixcluster">
  <logging debug="off"/>
  <clusternodes>
  <clusternode name="zabbix02" nodeid="1">
  <fence>
  <method name="pcmk-redirect">
  <device name="pcmk" port="zabbix02"/>
  </method>
  </fence>
  </clusternode>
  <clusternode name="zabbix01" nodeid="2">
  <fence>
  <method name="pcmk-redirect">
  <device name="pcmk" port="zabbix01"/>
  </method>
  </fence>
  </clusternode>
  </clusternodes>
  <fencedevices>
  <fencedevice name="pcmk" agent="fence_pcmk"/>
  </fencedevices>
  <cman> <multicast addr="226.94.1.1"/></cman> => when running more clusters in same network change multicast address
  </cluster>
九、检查配置文件并开机自启
  ccs_config_validate
  service cman start
  cman_tool nodes
  service pacemaker start
  chkconfig cman on
  chkconfig pacemaker on
十、资源配置
  pcs cluster auth zabbix01 zabbix02 #节点间认证
  pcs cluster start --all #启动集群中所有节点
  pcs resource create ClusterIP IPaddr2 ip=192.168.8.47 cidr_netmask=32 op monitor interval=2s #创建一个名为ClusterIP,类型是IPadd2,VIP是192.168.8.47/32 每隔2秒检测一次的资源
  pcs property set stonith-enabled=false #因我们没有STONITH设备,所以我们先关闭这个属性
  pcs resource create zabbix-server lsb:zabbix_server op monitor interval=5s #创建一个名为zabbix-server、标准是lsb、应用是zabbis_server,每隔5秒检测一次的资源。lsb指/etc/init.d/下的启动脚本
  pcs resource group add zabbix ClusterIP zabbix-server#将ClusterIPzabbix-server资源加入到zabbix资源组中
  pcs property set no-quorum-policy="ignore"#忽略法定人数不足时进行仲裁
  pcs property set default-resource-stickiness="100" #资源粘性为100
  pcs constraint colocation add zabbix-server ClusterIP #资源共置
  pcs constraint order ClusterIP then zabbix-server#资源限制,确保VIP和service在同一个节点上运行,而且VIP要在service之前完成。
  pcs constraint location ClusterIP prefers zabbix01 #ClusterIP更喜欢在zabbix01节点上,可用于节点故障恢复
  pcs constraint location zabbix-server prefers zabbix01 #zabbix-server更喜欢在zabbix01节点上,可用于故障恢复
十一、验证
  1、在zabbix01上操作停止zabbix_server 服务

  3、查看资源
  # pcs resource
  Resource Group: zabbix
  ClusterIP (ocf::heartbeat:IPaddr2): Started zabbix01
  zabbix-server (lsb:zabbix_server): Started zabbix01
  4、查看资源组
  #pcs resource group list
  zabbix: ClusterIP zabbix-server
十三、zabbix启动脚本
  # cat /etc/init.d/zabbix_server
  #!/bin/bash
  #Location of zabbix binary. Change path as neccessary
  DAEMON=/usr/local/zabbix/sbin/zabbix_server
  NAME=`basename $DAEMON`
  #Pid file of zabbix, should be matched with pid directive in nginx config file.
  PIDFILE=/tmp/$NAME.pid
  #this file location
  SCRIPTNAME=/etc/init.d/$NAME
  #only run if binary can be found
  test -x $DAEMON || exit 0
  RETVAL=0
  start() {
  echo $"Starting $NAME"
  $DAEMON
  RETVAL=0
  }
  stop() {
  echo $"Graceful stopping $NAME"
[ -s "$PIDFILE" ] && kill -QUIT `cat $PIDFILE`
  RETVAL=0
  }
  forcestop() {
  echo $"Quick stopping $NAME"

  RETVAL=$?
  }
  reload() {

  echo $"Graceful>[ -s "$PIDFILE" ] && kill -HUP `cat $PIDFILE`
  RETVAL=$?
  }
  status() {
  if [ -s $PIDFILE ]; then
  echo $"$NAME is running."
  RETVAL=0
  else
  echo $"$NAME stopped."
  RETVAL=3
  fi
  }
  # See how we were called.
  case "$1" in
  start)
  start
  ;;
  stop)
  stop
  ;;
  force-stop)
  forcestop
  ;;
  restart)
  stop
  start
  ;;
  reload)
  reload
  ;;
  status)
  status
  ;;
  *)
  echo $"Usage: $0 {start|stop|force-stop|restart|reload|status}"
  exit 1
  esac
  exit $RETVAL
