报错是系统libncurses.so.6动态库损坏，vim 启动符号解析失败，OBD 配置本身校验没问题。最快临时解决：EDITOR=vi obd cluster edit-config CLUSTER 用 vi 替代 vim 编辑；彻底修复：yum reinstall ncurses vim-enhanced 重装依赖库；也可以直接手动去 ~/.obd/cluster/集群名/config.yaml 修改文件再执行 obd cluster reload。

这个错误很常见，通常是因为 Vim 在运行时找不到它需要的 libtinfo 库中的某些符号。现在很多 Linux 发行版将 libtinfo 的功能整合进了 libncurses 库中。当程序（如 Vim）仍按旧习惯去查找 libtinfo.so.6 时，就会报错。可用如下方法解决
创建 libtinfo 的软链接
sudo ln -s /lib64/libncurses.so.6 /lib64/libtinfo.so.6

可以重新安装libncurses.so.6。
