Heartbeat-Gui V2 实现HA LAMP 搭建wordpress博客
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 root@x.x.x.x
[*]
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 ntpdatestart
# # 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 -Uivhftp://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
# 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 "<h1>node1</h1>" > /var/www/html/index.html //node1执行
# echo "<h1>node2</h1>" > /var/www/html/index.html //node2执行
# curl node{1,2} //访问测试
<h1>node1</h1>
<h1>node2</h1>
# service httpd stop ;ssh node2 'service httpd stop'
Stopping httpd:
Stopping httpd:
# 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
httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[*]
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.servicePerconaMySQL 安装：
# mount -t nfs 172.16.0.3:/data/mydata /mydata //挂载nfs文件至本地
# yum install openssl-devel -yes //安装openssl-devel包，至此Preconamysql的ssl
# cd /usr/lib64 //进入lib64# ln -s libssl.so.1.0.1e libssl.so.6 //软连接，因为Preconamysql要依赖该库，但是我们系统上的是libssl.so.1.0.1e
# ln -sv libcrypto.so libcrypto.so.6 //软连接，因为Preconamysql要依赖该库，但是我们系统上的是libcrypto.so
# tar xf /usr/local/src/Percona-Server-5.6.27-rel76.0-Linux.x86_64.ssl098e.tar.gz -C /usr/local //解压缩至/usr/local,个人习惯
# cd /usr/local //进入local
# ln -sv Percona-Server-5.6.27-rel76.0-Linux.x86_64.ssl098e.tar.gz mysql //不要问为什么，大家都这么做
# groupadd -g 306 mysql //新建组，指定GID306
# useradd -g 306 -u 306 -r -M mysql //新建用户，指定GID,UID为306
# mkdir /mydata //创建NFS挂载点
# cd /usr/local/mysql //进入程序包
# chown -R mysql.mysql ./ //-R递归
# scripts/mysql_install_db --datadir=/mydata/ --user=mysql //初始化
# cp -psupport-files/mysql.server /etc/init.d/mysqld //拷贝启动脚本
# vim /etc/my.cnf //mysql的配置文件,里面的参数我调的很小，是因为仅做博客测试使用

[*]
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 777wordpress
[*]
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
