Question

在ICP上进行CAM 2.1.0.2全新安装后，运行以下命令：

kubectl -n services get pods

我注意到“cam-bpd-ui”pod没有启动。所以我无法登录Process Designer UI并收到错误："Readiness probe failed: HTTP probe failed with statuscode: 404".

根据ICP概述窗格，它正在运行且可用。但是我在日志中看到了这一点

 "[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

Answer 1

Process Designer（BPD）需要连接到mariadb才能填充。您需要100％确定数据库是否正常运行。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具有/ export *（rw，insecure，no_subtree_check，async，no_root_squash）

有关no_root_squash的详细信息，请点击此处链接：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。详情请见：
