对我来说，apachectl -V不起作用，但apachectl fullstatus给了我我的版本。

或者，不那么直接地说:

nmap -A localhost -p

用sudo试试

apachectl -V
-bash: apachectl: command not found

sudo apachectl -V

对于更新的Debian或Ubuntu发行版，应该使用apache2ctl -v或apache2 -v。

apache:/etc/apache2# apache2ctl -v
Server version: Apache/2.2.16 (Debian)
Server built:   May 12 2011 11:58:18

或者您可以使用apache2 -V获取更多信息。

apache2 -V

我使用红帽Linux和以下命令工作:

httpd -V

我认为您必须确定您有二进制文件或源文件的安装类型。 要检查安装了哪些二进制包:具有root权限执行以下命令:

dpkg -l |grep apache2

结果应该是这样的:

dpkg -l |grep apache2

ii  apache2                               2.4.10-10+deb8u8                      amd64        Apache HTTP Server
ii  apache2-bin                           2.4.10-10+deb8u8                      amd64        Apache HTTP Server (modules and other binary files)
ii  apache2-data                          2.4.10-10+deb8u8                      all          Apache HTTP Server (common files)
ii  apache2-doc                           2.4.10-10+deb8u8                      all          Apache HTTP Server (on-site documentation)

要查找版本，您可以运行:

apache2ctl -V |grep -i "Server version"

结果应该是这样的: 服务器版本:Apache/2.4.10 (Debian)
