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
