Linux 配置keepalived

一、环境说明

1、操作系统内核版本：2.6.9-78.ELsmp

    2、Keepalived软件版本：keepalived-1.1.20.tar.gz

二、环境配置

1、主Keepalived服务器IP地址 192.168.111.223

2、备Keepalived服务器IP地址  192.168.111.100

3、Keepalived虚拟IP地址  192.168.111.150

三、软件下载地址

      http://www.keepalived.org/software/keepalived-1.1.20.tar.gz

四、安装流程

   1、上传Keepalived至/home/目录

    2、解压Keepalived软件

      [root@localhost home]# tar -zxvf keepalived-1.1.20.tar.gz 

      [root@localhost home]# cd keepalived-1.1.20

      [root@localhost keepalived-1.1.20]# ln -s /usr/src/kernels/2.6.9-78.EL-i686/usr/src//linux

      [root@localhost keepalived-1.1.20]# ./configure 

遇到错误提示：configure: error: Popt libraries is required

这个错误是因为没有安装popt的开发包导致的，解决方法也很简单，只要yum install popt-devel 就可以安装好popt的开发包了。

重新./configure

没有遇到跳过这一步

   3、提示

   4、编译以及编译安装

      [root@localhost keepalived-1.1.20]# make && make install

      5、将types.h调用的部分注释掉即可解决4出现的问题

     vi/usr/src/kernels/2.6.9-78.EL-i686/include/linux/types.h 

     到158行操作如下

   #endif 

 6、重新编译以及编译安装

     [root@localhost keepalived-1.1.20]# make && make install

   7、修改配置文件路径

       [[email protected]]#cp/usr/local/etc/rc.d/init.d/keepalived/etc/rc.d/init.d/

       [[email protected]]# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/

       [root@localhost keepalived-1.1.20]# mkdir /etc/keepalived

       [[email protected]]#cp /usr/local/etc/keepalived/keepalived.conf/etc/keepalived/                           

       [root@localhost keepalived-1.1.20]# cp /usr/local/sbin/keepalived /usr/sbin/

   8、设置为服务，开机启动

       [root@localhost keepalived-1.1.20]# vi /etc/rc.local 

五、主Keepalived配置

     1、修改配置文件

        [root@localhost keepalived-1.1.20]# vi /etc/keepalived/keepalived.conf 

六、备Keepalived配置

       1、修改配置文件

七、启动服务

八、查看网卡信息

 1、主Keepalived网卡信息

九、验证测试

 1、在主服务器上新建一个网页，内容为 192.168.111.223

 2、在备用服务器上新建一个网页，内容为 192.168.111.100

 3、启动主备服务器的http服务和Keepalived服务

 4、通过浏览数，输入虚拟IP地址 192.168.111.150

        页面显示为 192.168.111.223

5、关闭主服务器的Keepalived服务，通过浏览器输入IP地址192.168.111.150

        页面显示为 192.168.111.100

6、再次启动主服务器的Keepalived服务，通过浏览器输入IP地址192.168.111.150

        页面显示为 192.168.111.223
