環(huán)境：
N F S: 172.16.0.3 （OS CentOS 7）
node1：172.16.0.5 （OS CentOS 6.7）
node2：172.16.0.6 （OS CentOS 6.7）
浮動(dòng)IP：172.16.0.168
# yum install php php-mysql 倆個(gè)節(jié)點(diǎn)都安裝
互信操作：倆邊都操作：
# ssh-keygen -t rsa # ssh-copy-id -i .ssh/id_rsa.pub root@x.x.x.x
修改主機(jī)名：
# cat /etc/sysconfig/network //node2 NETWORKING=yes HOSTNAME=node2.sunshine.com # cat /etc/sysconfig/network //node1 NETWORKING=yes HOSTNAME=node1.sunshine.com
本地/etc/hosts解析：
# cat /etc/hosts | tail -2 172.16.0.5 node2.sunshine.com node2 172.16.0.6 node1.sunshine.com node1 # cat /etc/hosts | tail -2 172.16.0.5 node2.sunshine.com node2 172.16.0.6 node1.sunshine.com node1
同步時(shí)間：兩邊都操作,這里測(cè)試就不做crontab 不同時(shí)間了：
# service ntpdate start # [root@HA2 ~]# date ;ssh node2 'date' Wed Oct 26 15:28:32 CST 2016 Wed Oct 26 15:28:32 CST 2016
重啟：
# shutdown -r now
安裝epel源：
# rpm -Uivh ftp://ftp.pbone.net/mirror/dl.iuscommunity.org/pub/ius/archive/Redhat/6/i386/epel-release-6-5.noarch.rpm
安裝依賴：
# yum install net-snmp-libs libnet PyXML pygtk2-libglade -y
安裝Heartbeat相關(guān)程序包:找不到的同學(xué)別灰心我的百度云盤：http://pan.baidu.com/s/1boGx6t5
# rpm -ivh heartbeat-2.1.4-12.el6.x86_64.rpm \ > heartbeat-stonith-2.1.4-12.el6.x86_64.rpm > heartbeat-pils-2.1.4-12.el6.x86_64.rpm > heartbeat-gui-2.1.4-12.el6.x86_64.rpm
如報(bào)以下錯(cuò)誤：安裝libtool-ltdl 既可以：
error: Failed dependencies: libltdl.so.7()(64bit) is needed by heartbeat-2.1.4-12.el6.x86_64 libltdl.so.7()(64bit) is needed by heartbeat-stonith-2.1.4-12.el6.x86_64 libltdl.so.7()(64bit) is needed by heartbeat-pils-2.1.4-12.el6.x86_64# yum install libtool-ltdl -y //安裝libtool-ltdl
-安裝支持xshell Xmanger包，否則網(wǎng)絡(luò)上很方法也是不可用的：
# yum install xorg-x11-xauth //如果不安裝使用hb_gui是無(wú)法調(diào)用x11
ha.cf配置：
# grep -v "#" ha.cf logfile /var/log/heartbeat-log mcast eth0 225.10.210.1 694 1 0 auto_failback on node node1.sunshine.com node node2.sunshine.com crm on ping 172.16.0.1 # grep -v "#" authkeys auth 2 2 sha1 Dn880wJZxfsUpioJWy7FgQ # passwd hacluster //在哪里啟動(dòng)，就在哪里設(shè)置hacluster密碼 # hb_gui & compression bz2compression_threshold 2
authkeys配置
[root@node2 ha.d]# cat authkeys | tail -4 | grep -v "#"auth 22 sha1 Dn880wJZxfsUpioJWy7FgQ
在node{1|2}清除iptables并關(guān)閉selinux
# iptables -F# setenforce 0# cat /etc/selinux/config | tail -3 | head -1 SELINUXTYPE=targeted
