rc.local中命令没执行？

Question

单独执行rc.local文件正常、单独执行命令正常、root下hub文件记录正常，就是开机自动执行不正常，求解！！！

Answer 1

我只想说，那段被你忽视的注释部分已经解答了你的疑惑

Answer 2

Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
that this script will be executed during boot.

Answer 3

exec 2> /tmp/rc.local.log  # send stderr from rc.local to a log file
exec 1>&2                      # send stdout to the same log file

如果运行了，会有相应的文件生产
