撒哈拉未能启动

这是一个好主意。问题是需要设置

revocation\u cache\u time

设置，否则它会将其视为字符串。只需在

/etc/ceilometer/ceilometer.conf中取消对设置的注释，然后重新启动服务。
谢谢您的回答，不，它不起作用，也没有什么要取消注释的，我想问题出在文件
文件/usr/local/lib/python2.7/dist packages/keystenemiddleware/auth_token.py”，第661行，在uuu init_uuuuuu2015-02-15 20:53:22.820秒=self._conf_get（'revocation_cache_time'））
我不确定我应该用什么替换revocation_cache_time？有什么话要说吗？
