2、tar -xvzf keepalived-2.1.5.tar.gz
3、進入對應目錄，configure --prefix=/usr/local/keepalived
4、顯示缺少openssl
安裝openssl ， yum install openssl
5、重新編譯並安裝 make && make install
6、安裝後拷貝需要如下操作
cp /usr/local/keepalived/sbin/keepalived /etc/init.d/
cp /usr/local/keepalived/sbin/keepalived /etc/sysconfig/
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
7、cd /etc/
mkdir keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
8、配置keepalived.conf
主：! configuration file for keepalived
global_defs
notification_email_from [email protected] #發件人郵箱
smtp_server 192.168.200.1 #
smtp_connect_timeout 30
router_id lvs_devel #需要配置，成員名 lvs_devel 和備機上不能重複
}vrrp_instance vi_1
virtual_ipaddress
}----其他的配置基本都是用於lvs，可刪除
備：! configuration file for keepalived
global_defs
notification_email_from [email protected]
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id lvs_devel2 #需要配置
}vrrp_instance vi_1
virtual_ipaddress
}9、啟停keepalived
systemctl start keepalived
systemctl stop keepalived
10、檢視生效的ip
ip addr | grep 192.168.64.198
主機停止keepalived,ip 會自動在備機上生效。
