檢視Apache是否被安裝：

[[email protected] ~]#find / -name 'httpd'
/etc/sysconfig/httpd
/etc/httpd
/etc/logrotate.d/httpd
/etc/rc.d/init.d/httpd
/var/run/httpd
/var/log/httpd
/var/lock/subsys/httpd
/usr/sbin/httpd
/usr/lib64/httpd

由此確定Apache被安裝的地方是/etc/httpd

檢視Apache版本

首先進入httpd所在目錄
[[email protected] ~]#cd /etc/httpd

進而檢視版本
[[email protected]

停止httpd
[[email protected] httpd]#service httpd stop

啟動httpd
[[email protected] httpd]#service httpd start
