一、环境说明

1、操作系统内核版本：linux 6.0

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][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

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

这个错误发球胜的原理是由于因为没有安装popt的开发包导致的，只要yum install popt-devel 就可以安装好popt的开发包了。

重新./configure即可

4、编译以及编译安装

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

当出现编译和暗转问题时，可以将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

\#endif

5、修改配置文件路径

[\[root@localhostkeepalived-1.1.20\]\#cp/usr/local/etc/rc.d/init.d/keepalived/etc/rc.d/init.d/][root_localhostkeepalived-1.1.20_cp_usr_local_etc_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][root_localhostkeepalived-1.1.20_cp_usr_local_etc_rc.d_init.d_keepalived_etc_rc.d_init.d] /usr/local/etc/keepalived/keepalived.conf/etc/keepalived/

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

6、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、修改配置文件和启动服务

![1668067-20190428165728057-692055223.png][]

八、查看网卡信息

1、主Keepalived网卡信息

![1668067-20190428165807093-1766101577.png][]

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
