在 ICP 上全新安装 CAM 2.1.0.2 后，运行以下命令：

kubectl -n services get pods

我注意到“cam-bpd-ui”吊舱没有启动。所以我无法登录到 Process Designer UI，我收到了错误："Readiness probe failed: HTTP probe failed with statuscode: 404".

根据 ICP 概览窗格，它正在运行且可用。但是我在日志中看到了这个

 "[Warning] Failed to load slave replication state from table mysql.gtid_slave_pos: 1146: Table 'mysql.gtid_slave_pos' doesn't exist
Version: '10.1.16-MariaDB-1~jessie'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  mariadb.org binary distribution

检查 cam-bpd-ui pod 中的事件时，我们会看到以下内容：

kubectl describe pod cam-bpd-ui-687764b5fc-qxjnp -n services
Name:           cam-bpd-ui-687764b5fc-qxjnp

Process Designer (BPD) 需要连接到 mariadb 以便它可以填充。您需要 100% 确定数据库正常运行。如果不是，bpd 将不会为您返回登录页面。

一些提示：

1) 如果您有 NFS，请确保 /etc/exports 有 /export *(rw,insecure,no_subtree_check,async,no_root_squash)

有关 no_root_squash 的更多详细信息，您可以在此处查看链接：https ://www.digitalocean.com/community/tutorials/how-to-set-up-an-nfs-mount-on-ubuntu-16-04

作为解决方法，您可以执行以下操作：

您可以设置自己的数据库并进行配置，以便 BPD 使用它。详细信息可以在这里找到：
