[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
3、提示
4、編譯以及編譯安裝
[root@localhost keepalived-1.1.20]# make && make install
5、將types.h調用的部分注釋掉即可解決4出現的問題
vi/usr/src/kernels/2.6.9-78.EL-i686/include/linux/types.h

7、修改配置文件路徑
[root@localhostkeepalived-1.1.20]#cp/usr/local/etc/rc.d/init.d/keepalived/etc/rc.d/init.d/
[root@localhostkeepalived-1.1.20]# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/
[root@localhost keepalived-1.1.20]# mkdir /etc/keepalived
[root@localhostkeepalived-1.1.20]#cp /usr/local/etc/keepalived/keepalived.conf/etc/keepalived/
[root@localhost keepalived-1.1.20]# cp /usr/local/sbin/keepalived /usr/sbin/

[root@localhost keepalived-1.1.20]# vi /etc/keepalived/keepalived.conf
六、備Keepalived配置
1、修改配置文件
七、啟動服務
八、查看網卡信息
1、主Keepalived網卡信息
九、驗證測試
1、在主服務器上新建一個網頁，內容為 192.168.111.223
2、在備用服務器上新建一個網頁，內容為 192.168.111.100
