启动容器出现失败的情况
笔者在安装成功之后发现三个容器启动失败。
而 rbd-chaos & rbd-worker 依赖rbd-db。
所以主要问题为解决rbd-db容器的失败

解决方案：
删除数据库原来的数据，重新启动 rbd-db 容器，此时会正常启动
rm -rf /opt/rainbond/data/mysql/data/
docker start rbd-db
启动 rbd-chaos & rbd-worker (需要 rbd-db 正常启动)
/opt/rainbond/.init/updatedb.sh prepare
/opt/rainbond/.init/updatedb.sh migrate
/opt/rainbond/.init/updatedb.sh config

此时一个节点连接上集群了，但是未上线计算节点。只需要上线服务器资源即可 (使用uid)
grctl node up 959eba4b-6bbe-4ad5-ba0f-ecfad17d378d
命令
grclis stop <服务名> //关闭云帮所有服务
grclis start <服务名>
grclis upgrade <服务名/all/node/plugins>
grclis reset
# 建议使用root执行安装操作
grctl node add --host computexx --iip 计算节点IP --root-pass root用户密码 --role compute --install
示例：
grctl node add --host compute01 --iip 192.168.1.1 --root-pass 12345678 --role compute --install
grctl node list
# 确定节点处于健康状态上线节点
grctl node up <NodeID>
