今天升级kali 导致apache 无法启动，问题如下：
root@kali:~# apache2 -k start

1 2	[Sat Jan 21 21:01:16.273933 2017] [core:warn] [pid 3248] AH00111: Config variable ${APACHE_RUN_DIR} is not defined apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

1 2 3 4 5 6 7 8 9 10

或： root@kali:/etc/apache2# apache2 -k start [Sat Jan 21 22:05:56.705639 2017] [core:warn] [pid 10577] AH00111: Config variable ${APACHE_PID_FILE} is not defined [Sat Jan 21 22:05:56.705819 2017] [core:warn] [pid 10577] AH00111: Config variable ${APACHE_RUN_USER} is not defined [Sat Jan 21 22:05:56.705866 2017] [core:warn] [pid 10577] AH00111: Config variable ${APACHE_RUN_GROUP} is not defined [Sat Jan 21 22:05:56.705919 2017] [core:warn] [pid 10577] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Sat Jan 21 22:05:56.713958 2017] [core:warn] [pid 10577:tid 3073427200] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Sat Jan 21 22:05:56.714454 2017] [core:warn] [pid 10577:tid 3073427200] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Sat Jan 21 22:05:56.715159 2017] [core:warn] [pid 10577:tid 3073427200] AH00111: Config variable ${APACHE_LOG_DIR} is not defined AH00543: apache2: bad user name ${APACHE_RUN_USER}

这是由于升级后apache 配置文件变化，没有导入新的apache 环境变量。
解决办法 :

1	source /etc/apache2/envvars

或

1	. /etc/apache2/envvars
