Question

Cloudant本地数据版本：1.0.0.3

Linux发行版和版本：centos 6.6

我最近安装了Cloudant本地数据版本，在4节点集群（1个负载均衡器和3个数据节点）上正确配置。一切看起来很好，然后发出一些curl命令来创建，检索和删除数据库，但得到了internal_server_error。当我启动cloudant仪表板并以管理员身份输入时，指定的操作实际上是在终端上发生的我收到了错误消息。

命令代码段

[root@******1983 etc]# curl -X GET -u admin:****  http://*******/_all_dbs
["_users","first_data","first_testing_database","metrics","metrics_app","new","stats","t1","t_alpha"]
[root@******1983 etc]# curl -X GET -u admin:****  http://********/t_alpha
{"error":"error","reason":"internal_server_error",}
[root@******1983 etc]# curl -X DELETE -u admin:**** http://********/t_alpha
{"error":"error","reason":"internal_server_error",}

我使用说明使用Weatherreport实用程序来检查Cloudant群集的运行状况。我使用export命令设置路径： export PATH = $ PATH：/ opt / cloudant / bin 然后运行weatherreport，但它说“无法连接到本地群集节点”。我已经在/ etc / hosts，/ etc / sysconfig / network，/ etc / resolve.conf中提供了我所有4个节点的完整地址

Answer 1

Cloudant Local使用FQDN在节点之间进行通信。请确保所有节点（负载均衡器和数据库节点）上的/ etc / hosts中的所有节点都具有正确的FQDN和相应的IP地址。即
192.168.0.10 lb1.cloudant.local lb1
192.168.0.11 db1.cloudant.local db1
192.168.0.12 db2.cloudant.local db2
192.168.0.13 db3.cloudant.local db3

/etc/resolv.conf（不是resolve.conf ^^）应该（仅）包含所有节点上的DNS IP地址。即
nameserver 192.168.0.1
nameserver 8.8.4.4

AFAIK，/ etc / sysconfig / network仅适用于Debian / Ubuntu，仅包含本地计算机的网络信息。

Answer 2

检查/opt/cloudant/etc/vm.args文件。您已使用计算机名称设置了错误的-name参数。从错误消息

中可以清楚地看到这一点

"Could not connect to the local cluster node 'cloudant@********#'.

这里额外的＃出现在机器名称的末尾。
