连接远程scylla数据库服务器显示错误

Question

我在谷歌云服务器上安装了scylla-db.

我遵循的步骤:

sudo yum install epel-release

sudo curl -o /etc/yum.repos.d/scylla.repo -L http://repositories.scylladb.com/scylla/repo/a2a0ba89d456770dfdc1cd70325e3291/centos/scylladb-2.0.repo

sudo yum install scylla

sudo scylla_setup

(Given yes to "verify supportable version" , " verify packages" , "core dump", " fstim ssd "
For remaining : Given NO)

IN  file :/etc/scylla.d/io.conf

SEASTAR_IO="--max-io-requests=12 --num-io-queues=1"
( edited this file manually )

sudo systemctl start scylla-server

它显示:无法读取yaml文件.然后google它并将yaml-cpp版本从0.5.3版本降级到0.5.1. 然后scylla-server开始运行.

scylla-server正在运行.

相同的设置完成另一个服务器服务器名称scylla-db-1

我需要从此服务器连接到服务器scylla(IP:xx.xx.xxx).

当我执行以下内容时:

[root@scylla-db-1 ~]# cqlsh xx.xx.xxx
Connection error: ('Unable to connect to any servers', {'xx.xx.xxx': error(111, "Tried connecting to [('xx.xx.xxx', 9042)]. Last error: Connection refused")})

如何从此服务器连接远程服务器？

同时在浏览器中检查http://xx.xx.xxx:10000 和http://xx.xx.xxx:10000/ui时,我遇到问题加载页面.

注意 :

我已经完成了对/etc/scylla.d/io.conf文件的编辑,以便手动分配max-io-requests

Answer 1

端口10000是scylla的其余api,通常被限制在127.0.0.1 - 这就是为什么你无法访问它

要通过cql访问,您需要编辑/etc/scylla/scylla.yaml文件并设置rpc_address

请按照有关为群集部署配置scylla的说明进行操作:单个dc http://docs.scylladb.com/procedures/create_cluster/或multi dc http://docs.scylladb.com/procedures/create_cluster_multidc/.
