SequoiaDB 5.0.1 安装时db.createCataRG报错uncaught exception: -15 Network error

本文介绍在SequoiaDB 5.0.1 安装时,在创建编目节点组时报错 db.createCataRG(“sdbserver1”, 11800, “/opt/sequoiadb/database/cata/11800”) (shell):1 uncaught exception: -15 Network error。需要将第一个参数改成本地的主机名domain才可以。

现象

[sdbadmin@gbase_rh7_001 ~]$ sdb
Welcome to SequoiaDB shell!

分析

查看日志,发现如下内容

/opt/sequoiadb/database/coord/18800/diaglog/sdbdiag.log

发现是ossSocket连接报错:Failed to connect, rc = 101,查看 Linux操作系统错误码,是

OS error code 101: Network is unreachable

操作系统错误代码101:网络不可达

对照代码,发现sdbserver1并不是本机的主机名,也不是IP地址。

^C

解决方案

将参数改成本地的主机名即可。

> db.createCataRG("gbase_rh7_001", 11800, "/opt/sequoiadb/database/cata/11800")
Takes 3.166702s.
