配置好后启动keepalived，ip addr 发现没有vip增加。

经过检查发现、usr/local/keepalived/etc/sysconfig/keepalived文档没有配置

vim /usr/local/keepalived/etc/sysconfig/keepalived改KEEPALIVED_OPTIONS="-D"为KEEPALIVED_OPTIONS="-D -f /usr/local/keepalived/etc/keepalived/keepalived.conf"#修改制定keepalived要加载的配置文件，设置正确的服务启动参数

重启后，vip出现了。
