在CentOS 7上安装unixODBC失败：libodbcinst.so.1 =>找不到

Question

我正在尝试按照此处找到的步骤在CentOS7上安装unixODBC：

https://github.com/mkleehammer/pyodbc/wiki/Connecting-to-Oracle-from-RHEL-or-Centos

我已经完成了所有步骤，直到要求它测试oracle驱动程序istallation。运行dltest /usr/lib/oracle/11.2/client64/lib/libsqora.so.11.1时，出现以下错误：

# dltest /usr/lib/oracle/11.2/client64/lib/libsqora.so.11.1
[dltest] ERROR dlopen: file not found

然后我在libsqora.so.11.1文件上运行ldd：

# ldd libsqora.so.11.1
ldd: warning: you do not have execution permission for `./libsqora.so.11.1'
