我已经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。然后用谷歌搜索引擎并将yaml-cpp版本从0.5.3版本降级到0.5.1版本。
然后
scylla-server开始运行。

scylla服务器正在运行。
在另一台服务器上完成了相同的设置
服务器名称scylla-db-1
我需要从该服务器连接到服务器scylla(IP:xx.xx.xxx)。
当我执行以下命令时:
[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?
也
在浏览器中检查http://xx.xx.xxx:10000和http://xx.xx.xxx:10000/ui时,出现加载页面问题。
注意 :
我已经完成了/etc/scylla.d/io.conf文件的分配工作,
手动执行max-io-requests
最佳答案
端口10000是scylla的其余API,通常留在127.0.0.1范围内-这就是为什么您无法访问它的原因
要通过cql获得访问权限,您需要编辑/etc/scylla/scylla.yaml文件并设置rpc_address
请遵循为集群部署配置scylla的说明:single dc http://docs.scylladb.com/procedures/create_cluster/或multi dc http://docs.scylladb.com/procedures/create_cluster_multidc/。
