heartbeat 3.0.4-drbd 8.9-MySQL 5.6协同工作原理：首先，heartbeat作为高可用的控制角色，负责drbd存储服务目录的挂载（这里，drbd的启动个人理解是随主机启动自动启动的，其作用就是将主节点本地的一块盘与对端备节点的一块盘做数据同步、保证两端主机drbd相关的数据盘中数据完全一致），drbd的存储目录只在主节点挂载、接受读写，而备机保持不可用；当heartbeat完成drbd存储目录挂载后，启动mysql数据库，同时heartbeat负责检测drbd存储、mysql服务的状态，当服务异常，通过超时机制将资源在备机启动，从而达到mysql双机互备高可用的目的。 前提条件： 按照博文linux-ha heartbeat高可用的安装配置（http服务高可用）完成heartbeat的安装配置 按照博文MySQL 5.6 for REHL 6.4编译安装完成mysql的安装配置 heartbeat安装参考日志：linux-ha heartbeat高可用-基于http服务的安装配置 mysql的编译安装参考日志：MySQL安装方式-MySQL编译安装 一、DRBD软件的安装配置 主机名称 mymongo1 arbiter 管理IP eth0:192.168.199.131 eth0:192.168.199.134 DRBD管理名称 /data /data DRBD逻辑设备 /dev/drbd0 /dev/drbd0 DRBD对接IP eth2:192.168.144.132 eth2:192.168.144.111 DRBD存储设备 /dev/sdb1 /dev/sdb1 DRBD META设备 /dev/sdb2 [0] /dev/sdb2 [0] 虚拟IP eth2:192.168.144.122 eth2:192.168.144.122 1、两台vmware linux 虚拟机arbiter和mymongo1(两台主机需要新添加虚拟硬盘sdb)，基本信息 mymongo1 [root@mymongo1 ~]# hostname mymongo1 [root@mymongo1 ~]# uname -a Linux mymongo1 2.6.32-642.el6.x86_64 #1 SMP Tue May 10 17:27:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux [root@mymongo1 ~]# fdisk -l Disk /dev/sdb: 2147 MB, 2147483648 bytes 255 heads, 63 sectors/track, 261 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sda: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00061eae Device Boot Start End Blocks Id System /dev/sda1 * 1 39 307200 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 39 2350 18566144 83 Linux /dev/sda3 2350 2611 2097152 82 Linux swap / Solaris [root@mymongo1 ~]# cat /etc/redhat-release CentOS release 6.8 (Final) [root@mymongo1 ~]# arbiter [root@arbiter ~]# uname -a Linux arbiter 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux [root@arbiter ~]# hostname arbiter [root@arbiter ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.4 (Santiago) [root@arbiter ~]# fdisk -l Disk /dev/sda: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00078b06 Device Boot Start End Blocks Id System /dev/sda1 * 1 39 307200 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 39 549 4096000 82 Linux swap / Solaris Partition 2 does not end on cylinder boundary. /dev/sda3 549 2611 16567296 83 Linux Disk /dev/sdb: 2147 MB, 2147483648 bytes 255 heads, 63 sectors/track, 261 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 [root@arbiter ~]# 2、2台虚拟机sdb虚拟盘的分区表调整 [root@arbiter ~]# parted /dev/sdb mklabel gpt Information: You may need to update /etc/fstab.
