编译安装需要依赖的包，如gcc等：

yum -y install gcc gcc-c++ make glibc kernel-devel kernel-headers autoconf automake libtool glib2-devel libxml2 libxml2-devel libxslt-devel libtool-ltdl-devel wget asciidoc libuuid-devel bzip2 bzip2-devel e2fsprogs-devel net-snmp

防火墙及SELinux关闭；

时钟同步，ntp配置；

相关主机名配置，如下所示：

节点/主机名	业务IP	心跳IP
master1.yewu.com	192.168.88.100	192.168.77.100
master2.yewu.com	192.168.88.101	192.168.77.101
vip	192.168.88.88

 # hostnamectl set-hostname  master1.yewu.com

 # hostnamectl set-hostname  master2.yewu.com	#分别配置主机名

 # /etc/hosts

 127.0.0.1 localhost.localdomain localhost

 #public ip						#业务host解析

 192.168.88.100 master1.yewu.com master1

 192.168.88.101 master2.yewu.com master2

 #private ip						#Heartbeat心跳解析

 192.168.77.100 master1-private.ha.com master1-private

 192.168.77.101 master2-private.ha.com master2-private

 

提示：内网环境为了方便解析，在所有节点分别对业务和用于检测心跳的地址添加解析。

 [root@master1 ~]# ifconfig |grep eth[0-9] -A1		#确认相应IP地址
