Need to modify /etc/hosts,but no permission.
问题现象
SLB部署失败，日志详细信息提示如下：
"will new install"
"Need to modify /etc/hosts,but no permission."
问题分析
如果/etc/hosts文件自动部署用户没有写的权限，那么部署完之后，slb_agent的域名映射就会下发失败，导致业务部署完，无法在界面上对SLB机器执行同步、重启等操作。
解决方法
登录SLB实例主机，执行命令chmod 666 /etc/hosts，给/etc/hosts加上写的权限，默认是444，建议给666。
