环境：
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）
浮动IP：172.16.0.168
php php-mysql 安装：
# yum install php php-mysql 俩个节点都安装
Heartbeat 安装：
互信操作：俩边都操作：
# ssh-keygen -t rsa # ssh-copy-id -i .ssh/id_rsa.pub [email protected]
修改主机名：
# 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
同步时间：两边都操作,这里测试就不做crontab 不同时间了：
# 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
重启：
# shutdown -r now
安装epel源：
# rpm -Uivh ftp://ftp.pbone.net/mirror/dl.iuscommunity.org/pub/ius/archive/Redhat/6/i386/epel-release-6-5.noarch.rpm
安装依赖：
# yum install net-snmp-libs libnet PyXML pygtk2-libglade -y
安装Heartbeat相关程序包:找不到的同学别灰心我的百度云盘：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
如报以下错误：安装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 //安装libtool-ltdl
-安装支持xshell Xmanger包，否则网络上很方法也是不可用的：
# yum install xorg-x11-xauth //如果不安装使用hb_gui是无法调用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 //在哪里启动，就在哪里设置hacluster密码 # hb_gui & compression bz2 compression_threshold 2
authkeys配置
[root@node2 ha.d]# cat authkeys | tail -4 | grep -v "#" auth 2 2 sha1 Dn880wJZxfsUpioJWy7FgQ
在node{1|2}清除iptables并关闭selinux
# iptables -F# setenforce 0# cat /etc/selinux/config | tail -3 | head -1 SELINUXTYPE=targeted
httpd 安装：
# yum install httpd -y //node{1|2}
# echo "node1
" > /var/www/html/index.html //node1执行
# echo "node2
" > /var/www/html/index.html //node2执行
# curl node{1,2} //访问测试
node1
node2
# service httpd stop ;ssh node2 'service httpd stop'
Stopping httpd: [ OK ]
Stopping httpd: [ OK ]
# chkconfig httpd off ;ssh node2 'chkconfig httpd off' //关闭httpd自动启动
# chkconfig httpd --list ;ssh node2 'chkconfig httpd --list'//查看是否关闭

NFS Server搭建：这是在NFS服务器上执行
# groupadd -g 306 mysql # useradd -g 306 -u 306 -M -r mysql # mkdir /data/mydata # chown -R mysql.mysql /data/mydata # cat /etc/exports //编辑需要导出的文件 /data/mydata 172.16.0.0/24(rw,no_root_squash) //no_root_squash表示远端主机root用户不转换nobody用户 # systemctl start nfs.service //启动nfs服务 # cat /etc/rc.local | tail -1 //加入开机启动 /usr/bin/systemctl start nfs.service

安装博客
下载程序包
# cd /usr/local/src # wget https://cn.wordpress.org/wordpress-4.5.3-zh_CN.tar.gz
解压并设置 777 权限，这边为了方便
# tar xf wordpress-4.5.3-zh_CN.tar.gz -C /var/www/html/ # cd /var/www/html/ # chown -R 777 wordpress
手动启动mysql
# service mysqd start
进入mysql创建wordpress库，提供给wordpress初始化呢使用
# mysql -uroot -p //回车输入自己的密码，没设定密码直接回车 # CREATE DATABASE wordpess；
授权wordpress库权限，生产机建议不要使用通配符
# GRANT ALL ON wordpress.* TO wordpress@‘172.16.%.%' INDENTIFIED BY 'redhat'; # FLUSH PRIVILEGES;
博客初始化：先手动启动mysql，初始化完毕后再手动关闭mysql，这里太简单 不上图了
1、填上mysql地址：也就是我们的浮动IP：172.16.0.168
2、填上用户：在数据库创建的：wordpress
3、填上密码：redhat
4、其它根据自己定义填写即可。
Hearbeat-Gui资源配置：
# hb_gui &
1、Resources新建组资源，并命名，注意Parameters里面的值
2、访问测试
3、节点切换并访问测
