须要批改 apache httpd 加载配置文件httpd-info.conf

须要凋谢拜访 server-info 和server-status的权限

`docker`实现

创立 Dockerfile 如下

FROM httpd:2.4-alpine

# 启用 httpd info 模块
RUN sed -i "s|#Include conf/extra/httpd-info.conf|Include conf/extra/httpd-info.conf|g" /usr/local/apache2/conf/httpd.conf
# 加载 mod info 凋谢拜访 server info 信息
RUN sed -i "s|#LoadModule info_module modules/mod_info.so|LoadModule info_module modules/mod_info.so|g" /usr/local/apache2/conf/httpd.conf
# 配置容许近程拜访，防止 403 谬误
RUN sed -i "s/Require host .example.com/Order deny,allow/g" /usr/local/apache2/conf/extra/httpd-info.conf
RUN sed -i "s/Require ip 127/Allow from all/g" /usr/local/apache2/conf/extra/httpd-info.conf

创立compose.yaml

services:
  apache:
    container_name: demo-apache
    image: demo-apache
    build: .
    restart: always
    ports:
      - "80:80"

构建镜像

$ docker compose build

服务启动

$ docker compose up -d

查看拜访配置信息

$ docker exec demo-apache cat /usr/local/apache2/conf/extra/httpd-info.conf
....
<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Allow from all
</Location>
....
<Location /server-info>
    SetHandler server-info
    Order deny,allow
    Allow from all
</Location>
