apache服务资源监控

配置

需要修改apache httpd加载配置文件httpd-info.conf

需要开放访问server-info和server-status的权限

docker实现

创建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 开放访问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
# 配置允许远程访问，避免403错误
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

创建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

查看访问配置信息

$ 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>
