Heartbeat-Gui V2 实现HA LAMP 搭建wordpress博客

唐伯虎

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 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 "<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: [  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
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.service

PerconaMySQL 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 -p  support-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 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
