  # 对指定文件或文件夹添加权限（这个错误 600 、700 权限都能解决）
  $ chmod 700 xxx
  
  # 例如
  $ chmod 700 ./key/private.xxxx.key
  

  -rw------- (600) 只有拥有者有读写权限。
  -rw-r--r-- (644) 只有拥有者有读写权限；而属组用户和其他用户只有读权限。
  -rwx------ (700) 只有拥有者有读、写、执行权限。
  -rwxr-xr-x (755) 拥有者有读、写、执行权限；而属组用户和其他用户只有读、执行权限。
  -rwx--x--x (711) 拥有者有读、写、执行权限；而属组用户和其他用户只有执行权限。
