rancher服务在重启之后会报这个错误，并且无法访问GUI，解决方案。将rancher从1.X版本升级到2.X版本即可
1.拉取2.X镜像
$ docker pull rancher/rancher

2.创建宿主机挂载目录
$ mkdir -p /docker_volume/rancher_home/rancher
$ mkdir -p /docker_volume/rancher_home/auditlog

3.启动
$ docker run -d --restart=unless-stopped -p 80:80 -p 443:443
-v /docker_volume/rancher_home/rancher:/var/lib/rancher
-v /docker_volume/rancher_home/auditlog:/var/log/auditlog
–name rancher rancher/rancher

4.访问rancher的管理web页面：https://192.168.225.129

5.填写admin的密码及Ip

6.重启再次访问，访问成功，并不再出现错误
docker restart b95378991be0
