Keepalived问题
环境介绍：vmware版本：12.1.0 build-3272444
Keepalived（master）：centos7
Keepalived（backup）：centos7
Keepalived软件版本：keepalived-1.2.16.tar.gz
Keepalived安装路径：/usr/local/keepalived/
问题1：Keepalived的默认配置文件路径为/etc/keepalived/keepalived.conf；能通过修改配置文件/usr/local/keepalived/etc/sysconfig/keepalived中的KEEPALIVED_OPTIONS="-D -f /usr/local/keepalived/etc/keepalived/keepalived.conf"来指定配置文件路径；
问题2：当master和backup没有关闭firewalld防火墙时，通过ip addr能在master和backup上同时查看到vip；也就是说master和backup同时抢占了VIP,引发脑裂。
