我已经在谷歌云服务器中安装了 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。然后谷歌它并将yaml-cpp版本从0.5.3版本降级为0.5.1。 然后 scylla-server 开始运行。

scylla 服务器正在运行。
相同的设置已完成另一台服务器服务器名称 scylla-db-1
我需要从该服务器连接到服务器 scylla(IP:xx.xx.xxx)。
当我执行以下操作时:
[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?
此外,在浏览器中检查http://xx.xx.xxx:10000 和http://xx.xx.xxx:10000/ui时,我在加载页面时遇到问题。
笔记 :
我已经编辑了 /etc/scylla.d/io.conf 文件以手动分配 max-io-requests
