GBase 8a V86扩容报错总结及解决方案（1）

报错信息：

生成新distribution报错

Error: execute amd [scp -0 StrictHostKeyChecking-no -o UserknownHostsFiles/dev/null -q-r/usr/bin/gadm_cp_sys_tbl.py/usr/bin/pexpect.pygbase@***.***.***.***]:/tmp/failed, error no[1]

Error cause:

lost connection

解决方案：

报错的机器之间配置互信。

1.在客户端生成公钥私钥对

命令：ssh-keygen -t rsa

一路默认回车，系统在/root/.ssh下生成id_rsa、id_rsa.pub

2.将生成的公钥私钥对id_rsa.pub发送到其他的服务器上。

命令：ssh-copy-id -i /root/.ssh/id_rsa.pub 目标IP

注：命令可简单记忆为 ssh-copy-id -i 公钥私钥对文件 服务器ip地址

报错信息：

生成新distribution报错

ERROR 1251 (08004) : Client does not support authentication protocol requested by server: consider upgrading Base client。

Error: restart gbased failed

Error: execute cmd [ssh -o UserknowmHostsFile-/dev/null -o StrictHostkeyCheckingano gbase@ IP “export GBASE_ BASE -/opt/ gnode: . -/.gbase profile:python /tmp/gad _ cp_sys_ tbl-py copy db_ password-J failed. error no I12]

Error cause: Warning: Permanently added '10.86.126.1l9' (ECDSA) to the list of known hosts.

解决方案：

当出现如上一组报错信息时，说明数据库默认密码已经更改，需要在生成distribution中增加db_pwd XXXXX这个参数

如：gcadmin distribution gcChangeInfo.xml p 1 d 1 db_pwd gbase2022
