podman用脚本和dockerfile做apache编译安装镜像(alpine版)
alpine系统是什么
Alpine Linux 是一个基于 musl libc 和 busybox 的面向安全的轻量级 Linux 发行版。
alpine系统的特点
- 小巧:基于Musl libc和busybox,和busybox一样小巧,最小的Docker镜像只有5MB;
- 安全:面向安全的轻量发行版;
- 简单:提供APK包管理工具,软件的搜索、安装、删除、升级都非常方便。
- 适合容器使用:由于小巧、功能完备,非常适合作为容器的基础镜像。
alpine镜像下载
alpine国内源
清华大学:https://mirror.tuna.tsinghua.edu.cn/alpine/
阿里云:https://mirrors.aliyun.com/alpine/
网易:http://mirrors.163.com/
更换apk源
sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
alpine基础命令
apk update //更新最新镜像源列表
apk search //查找所以可用软件包
apk search -v //查找所以可用软件包及其描述内容
apk search -v ‘acf*’ //通过软件包名称查找软件包
apk search -v -d ‘docker’ //通过描述文件查找特定的软件包
apk add openssh //安装一个软件
apk add openssh openntp vim //安装多个软件
apk add --no-cache mysql-client //不使用本地镜像源缓存,相当于先执行update,再执行add
apk info //列出所有已安装的软件包
apk info -a zlib //显示完整的软件包信息
apk info --who-owns /sbin/lbu //显示指定文件属于的包
apk upgrade //升级所有软件
apk upgrade openssh //升级指定软件
apk upgrade openssh openntp vim //升级多个软件
apk add --upgrade busybox //指定升级部分软件包
apk del openssh //删除一个软件
服务管理
alpine没有使用fedora的systemctl来进行服务管理,使用的是RC系列命令:
rc-update //主要用于不同运行级增加或者删除服务
rc-status //主要用于运行级的状态管理
rc-service //主用于管理服务的状态
rc-status -a //列出系统所有服务
关闭系统
reboot //重启系统
poweroff //关机
podman用dockerfile做alpine编译安装镜像
