标签:drbd   heartbeat   mysql   

配置信息:

Primary:
Name:zbdba1
OS:redhat 6.3
IP:192.168.56.220
drbd:8.4.0
heartbeat:3.0.4

Standby:
Name:zbdba2
OS:Redhat 6.3
IP:192.168.56.221
drbd:8.4.0
heartbeat:3.0.4

主要分为如下步骤:
1、安装DRBD
2、安装Mysql
3、测试DRBD
4、安装Heartbeat
5、测试Heartbeat


1、安装DRBD
下载drbd:
wget http://oss.linbit.com/drbd/8.4/drbd-8.4.0.tar.gz


在zbdba1、zbdba2:
添加磁盘

Disk /dev/sdb: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 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
安装依赖包:

yum install gcc flex rpm-build kernel-devel docbook-style-xsl -y
建立rpm目录:

rpmbuild ~
解压并生成rpm包:
tar xvf drbd-8.4.0.tar.gz  尝试了8.4.3,版本太新 linux内核不兼容
./configure
make rpm 
make km-rpm
此时已经生成drbd的rpm包
进入安装:
cd /root/rpmbuild/RPMS/x86_64
yum install * -y
查看drbd模块:
modprobe drbd
lsmod |grep drbd
配置DRBD:

[root@zbdba1 etc]# cat drbd.conf
include "drbd.d/drbd.conf.example";

[root@zbdba1 etc]# cat drbd.d/drbd.conf.example
resource zbdba {
        options {
                on-no-data-accessible suspend-io;
        }

        net {
                cram-hmac-alg "sha1";
                shared-secret "secret_string";
        }

        # The disk section is possible on resource level and in each
        # volume section
        disk {
                # If you have a resonable RAID controller
                # with non volatile write cache (BBWC, flash)
                disk-flushes no;
                disk-barrier no;
                md-flushes no;
        }

        # volume sections on resource level, are inherited to all node
        # sections. Place it here if the backing devices have the same
        # device names on all your nodes.
#       volume 1 {
#               device minor 1;
#               disk /dev/sdb;
#               meta-disk internal;
#
#               disk {
#                       resync-after example/0;
#               }
#       }

        on zbdba1 {
                address 192.168.56.220:7780;

                volume 0 {
                       device minor 0;
                       disk /dev/sdb;
                       meta-disk internal;
                }
        }
        on zbdba2 {
                address 192.168.56.221:7780;

                volume 0 {
                       device minor 0;
                       disk /dev/sdb;
                       meta-disk internal;
                }
        }
}


drbdadm create-md zbdba

[root@zbdba1 etc]# service drbd start
[root@zbdba2 etc]# service drbd start
在zbdba1:

drbdsetup /dev/drbd0  primary --force
监控传输速率:
[root@Dbrd1 etc]# watch cat /proc/drbd
Every 2.0s: cat /proc/drbd                                                                                                                     Mon Jan 19 07:27:45 2015

    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0

其中:ro是角色信息:Primary/Secondary(代表这个是主节点)
                    Secondary/Primary(代表这个是副节点)

      ds是磁盘状态:UpToDate/Inconsistent(正在同步,数据还没有一致)
                    UpToDate/UpToDate    (同步完成,数据一致)
      ns是网络传输的数据包:以K为字节
    
      dw是磁盘写操作
      dr是磁盘读操作


挂载mysql目录:
mkdir /mysql
mkfs.ext4 /dev/drbd0
mount /dev/drbd0 /mysql
查看DRBD状态:

[root@zbdba1 ~]# service drbd status
drbd driver loaded OK; device status:
version: 8.4.0 (api:1/proto:86-100)
GIT-hash: 28753f559ab51b549d16bcf487fe625d5919c49c build by root@Dbrd1, 2015-01-19 03:52:17
m:res    cs         ro                 ds                 p  mounted  fstype
0:zbdba  Connected  Primary/Secondary  UpToDate/UpToDate  C  /mysql   ext4

[root@zbdba2 ~]# service drbd status
drbd driver loaded OK; device status:
version: 8.4.0 (api:1/proto:86-100)
GIT-hash: 28753f559ab51b549d16bcf487fe625d5919c49c build by root@Dbrd1, 2015-01-19 03:52:17
m:res    cs         ro                 ds                 p  mounted  fstype
0:zbdba  Connected  Secondary/Primary  UpToDate/UpToDate  C


2、安装Mysql:
tar -zxvf mysql-5.6.12-linux-glibc2.5-x86_64
mv mysql-5.6.12-linux-glibc2.5-x86_64 /mysql
添加用户
groupadd mysql
useradd mysql -g mysql
chown -R mysql.mysql mysql/


cp support-files/my-default.cnf /etc/my.cnf

在my.cnf中制定数据库基本目录:
[mysqld]
basedir =/mysql
datadir = /mysql/data

初始化数据库:
scripts/mysql_install_db --user=mysql


cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start


修改环境变量:
vi /root/.bash_profile
PATH=$PATH:$HOME/bin:/mysql/bin
3、测试DRBD:

在zbdba1:
service mysql stop

umount /dev/drbd0

drbdadm secondary zbdba

scp /etc/my.cnf zbdba2:`pwd`
在zbdba2:
drbdadm primary zbdba
mount /dev/drbd0 /mysql

cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on

启动mysql:
service mysql start
测试成功
4、安装Heartbeat:

在zbdba1、zbdba2:
cluster-glue-1.0.5-6.el6.x86_64
cluster-glue-libs-1.0.5-6.el6.x86_64
heartbeat-3.0.4-1.el6.x86_64
heartbeat-libs-3.0.4-1.el6.x86_64
perl-TimeDate-1.16-11.1.el6.noarch
resource-agents-3.9.2-21.el6.x86_6

yum install * -y

cp /usr/share/doc/heartbeat-3.0.4/ha.cf /etc/ha.d/ha.cf
cp /usr/share/doc/heartbeat-3.0.4/authkeys /etc/ha.d/authkeys
cp /usr/share/doc/heartbeat-3.0.4/haresources /etc/ha.d/haresources
配置文件内容如下:

[root@zbdba1 ha.d]# cat ha.cf
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility     local0
keepalive 2
deadtime 30
warntime 10
bcast   eth0            # Linux
#bcast  eth1 eth2       # Linux
#bcast  le0             # Solaris
#bcast  le1 le2         # Solaris
auto_failback on
node    zbdba1
node    zbdba2

[root@zbdba1 ha.d]# cat authkeys
auth 1
1 crc

[root@zbdba1 ha.d]# cat haresources
zbdba1 192.168.56.225/24/eth0 drbddisk::zbdba Filesystem::/dev/drbd0::/mysql::ext4 mysql

service heartbeat start

查看vip是否启动:
eth0:0    Link encap:Ethernet  HWaddr 08:00:27:EB:CE:6F 
          inet addr:192.168.56.225  Bcast:192.168.56.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1



tail -100f  /var/log/ha-log

配置成功
5、测试Heartbeat:

1、直接关闭hearbeat

[root@zbdba1 ha.d]# service heartbeat stop

监控zbdba1上ha-log日志:

哈哈,终于测试成功,heartbeat不会监控mysql服务是否正常、所以需要自己写脚本监控mysql的服务状态
