RHEL上的Kong安装问题

Question

我试图在RHEL机器上安装Kong，但在运行kong迁移命令时出现错误。"$ kong迁移向上-c /etc/kong/kong.conf“

2018/01/22 14:56:28 [verbose] running datastore migrations
Error:

我已经安装了Cassandra 3.11.1，并创建了一个名为'kong‘的密钥空间和角色。我错过了什么吗？

Answer 1

在将Cassandra RPC地址添加到/etc/cassandra/conf/cassandra.yml并为kong创建了一个工作目录(位于/usr/local/bin/kong)后，该问题得到了解决。授予用户对所有密匙空间的访问权限。
