1、系统版本:
[root@www-slave ha.d]# uname -r 3.10.0-862.9.1.el7.x86_64
2、主机
主机 | ip |
www-master | 10.10.10.109 |
www-slave | 10.10.10.108 |
3、基础准备
systemctl stop firewalld.service #关闭防火墙 sed -i ‘s/Enforcing/disabled/g‘ /etc/sysconfig/selinux #关闭selinux ntpdate 0.cn.pool.ntp.org #同步时间
4、host解析
10.10.10.109 www-master 10.10.10.108 www-slave
二、安装DRBD
1、添加附加库(两台都操作)
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
2、安装drbd(两台都操作)
yum install drbd84 kmod-drbd84 -y
3、磁盘分区(两台都操作)
Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): n Partition type: p primary (1 primary, 0 extended, 3 free) e extended Select (default p): p
不做磁盘初始化
4、开始配置drbd
modprobe drbd
提示:centos7没有这个模块,需要升级内核,yum install kenel* -y
5、修改配置文件/etc/drbd.d/global_common.conf(两台相同配置)
global { usage-count yes; } common { protocol C; disk { on-io-error detach; } syncer { rate 100M; #100M传输速度 } } resource nginx { on www-master{ device /dev/drbd0; disk /dev/sdb; address 10.10.10.109:7788; meta-disk internal; } on www-slave{ device /dev/drbd0; disk /dev/sdb; address 10.10.10.108:7788; meta-disk internal; } }
6、激活前面配置的DRBD资源nginx(两个节点都要执行)
drbdadm create-md nfs
7、启动drbd(两个节点都要执行)
systemctl start drbd
按提示输入 yes
8、一下几个步骤都在主上执行
drbdadm primary nginx #设置主 drbdadm -- --overwrite-data-of-peer primary nfs
watch -n1 ‘cat /proc/drbd‘
version: 8.4.11-1 (api:1/proto:86-101)

等状态同步完成之后,在主上执行一下
mkfs.ext4 /dev/drbd1
三、Heartbeat环境搭建
1、安装heartbeat依赖包
yum install -y bzip2 autoconf automake libtool glib2-devel libxml2-devel bzip2-devel libtool-ltdl-devel asciidoc libuuid-devel psmisc
2、安装glue
wget http://hg.linux-ha.org/glue/archive/0a7add1d9996.tar.bz2 tar jxvf 0a7add1d9996.tar.bz2 cd Reusable-Cluster-Components-glue--0a7add1d9996/ groupadd haclient useradd -g haclient hacluster ./autogen.sh ./configure --prefix=/usr/local/heartbeat/ make make install
3、安装Resource Agents
wget https://github.com/ClusterLabs/resource-agents/archive/v3.9.6.tar.gz tar zxvf v3.9.6.tar.gz cd resource-agents-3.9.6/ ./autogen.sh export CFLAGS="$CFLAGS -I/usr/local/heartbeat/include -L/usr/local/heartbeat/lib" ./configure --prefix=/usr/local/heartbeat/ vi /etc/ld.so.conf.d/heartbeat.conf #计入下边内容
/usr/local/heartbeat/lib
ldconfig make make install
4、安装HeartBeat
wget http://hg.linux-ha.org/heartbeat-STABLE_3_0/archive/958e11be8686.tar.bz2 tar jxvf 958e11be8686.tar.bz2 cd Heartbeat-3-0-958e11be8686 ./bootstrap export CFLAGS="$CFLAGS -I/usr/local/heartbeat/include -L/usr/local/heartbeat/lib" ./configure --prefix=/usr/local/heartbeat/ vi /usr/local/heartbeat/include/heartbeat/glue_config.h /*define HA_HBCONF_DIR “/usr/local/heartbeat/etc/ha.d/”*/ (注意这行用/**/注释掉) make make install
2、复制配置文件
cp /usr/local/heartbeat/share/doc/heartbeat/ha.cf /usr/local/heartbeat/etc/ha.d cp /usr/local/heartbeat/share/doc/heartbeat/authkeys /usr/local/heartbeat/etc/ha.d cp /usr/local/heartbeat/share/doc/heartbeat/haresources /usr/local/heartbeat/etc/ha.d
3、设置ha.cf配置文件(两台机器都操作)
debugfile /var/log/ha-debug #日志 logfile /var/log/ha-log keepalive 2 #设定检查时间间隔 warntime 10 #设定警告时间 deadtime 30 #设定在时间内没有心跳就立即切换服务 initdead 60 #初始化时间 udpport 1112 #设定集群节点间的通信协议及端口为udp1112 bcast em1 ucast em1 10.10.10.109 #设置心跳方式使用单播方式,并且在em1网卡上进行单播 ,ip地址为对方的IP #baud 19200 auto_failback off #当主节点恢复后,是否自动切回,一般都设为off node www-master #指定两个节点 node www-slave ping 10.10.10.1 #两个IP的网关 respawn hacluster /usr/local/heartbeat/libexec/heartbeat/ipfail #使用这个脚本去侦听对方是否还活着(使用的是ICMP报文检测)
4、编辑双机互联验证文件authkeys,添加以下内容:(node1,node2)
# vi /usr/local/heartbeat/etc/ha.d/authkeys auth 1 1 crc
5、给验证文件600权限
# chmod 600 /usr/local/heartbeat/etc/ha.d/authkeys
