Question

centos查看apache用的是哪个httpd.conf

Answer 1

果进程中无法找到尝试在启动脚本中寻找，适用于yum安装的apache，如下所示，可以看到启动时apache加载配置文件的位置，其中apache运行的站点目录可以在/etc/httpd/conf/httpd.conf中找到
#查看apache配置文件位置
sed -n '9,11p' /etc/init.d/httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd/httpd.pid
#查看apache站点目录
grep "DocumentRoot" /etc/httpd/conf/httpd.conf|grep -v "#"
DocumentRoot "/var/www/html"

3. 通过编译参数查找

apache_bin=$(find / -type f -name "httpd"|xargs -i ls -l {}|awk '{if($5>30000)print $NF}')
$apache_bin -V|grep HTTPD_ROOT
结果：-D HTTPD_ROOT="/etc/httpd"
#apache安装在/etc/httpd 目录下
