下文给大家带来如何直接用keepalived实现企业级WEB的负载均衡高可用性，希望能够给大家在实际运用中带来一定的帮助，负载均衡涉及的东西比较多，理论也不多，网上有很多书籍，今天我们就用亿速云在行业内累计的经验来做一个解答。

③编辑keepalived.conf文件，直接用keepalived实现负载均衡及高可用性。

a)Keepalved的安装

a)Keepalved的安装

#wgethttp://www.keepalived.org/software/keepalived-1.1.15.tar.gz

#tarzxvfkeepalived-1.1.15.tar.gz

#cdkeepalived-1.1.15

#./configure

#make

#makeinstall

将keepalived做成启动脚务，方便管理:

#cp/usr/local/etc/rc.d/init.d/keepalived/etc/rc.d/init.d/

#cp/usr/local/etc/sysconfig/keepalived/etc/sysconfig/

#mkdir/etc/keepalived

#cp/usr/local/etc/keepalived/keepalived.conf/etc/keepalived/

#cp/usr/local/sbin/keepalived/usr/sbin/

#servicekeepalivedstart|stop

b)Keealived的配置

①分别在主从负载均衡云服务器上配置keepalived.conf ，内容分别如下:

!ConfigurationFileforkeepalived

global_defs{

notification_email{

yuhongchun027@163.com

}

notification_email_fromsns-lvs@gmail.com

smtp_server127.0.0.1

}

vrrp_instanceVI_1{

stateMASTER

interfaceeth0

virtual_router_id51

priority100
