我在EC2实例上遇到了Apache2的小问题。 我安装LAMP，但是当我打电话给apache2我收到这个：
[Thu Dec 03 22:06:56.100599 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_LOCK_DIR} is not defined [Thu Dec 03 22:06:56.100721 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_PID_FILE} is not defined [Thu Dec 03 22:06:56.100777 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_RUN_USER} is not defined [Thu Dec 03 22:06:56.100824 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_RUN_GROUP} is not defined [Thu Dec 03 22:06:56.100871 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Thu Dec 03 22:06:56.105835 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Thu Dec 03 22:06:56.105971 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Thu Dec 03 22:06:56.106008 2015] [core:warn] [pid 31235] AH00111: Config variable ${APACHE_LOG_DIR} is not defined AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf: Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}
我尝试一切 – apt-get update ，再次安装LAMP，但没有任何工作。 我怎样才能设置这个configurationvariables？
是的，我试图在互联网上find解决scheme，但我不能。
直接从二进制调用Apache不包括使你的错误的envvars。
从init脚本启动，重新启动并停止Apache，或者使用
$ sudo service apache2 restart
要么
$ sudo apachectl restart
