Docker是一个开源的应用容器引擎,基于Go语言并遵从Apache2.0协议开源。
Docker可以让开发者打包他们的应用以及依赖包到一个轻量级、可移植的容器中,然后发布到任何流行的Linux机器上,也可以实现虚拟化。容器是完全使用沙箱机制,相互之间不会有任何接口(类似iPhone的app),更重要的是容器性能开销极低。
文章就不介绍如何去安装和使用docker了。不会的请大家自行谷歌/百度去学习下~
最新版的镜像地址,在我的阿里云仓库里面,文章末尾,可以直接使用命令docker pull获取。
先说下本人docker中部署lnmp环境使用的几个方法:
方法一:通过百度等方法,分别从一些镜像仓库拉取nginx、mysql、php镜像,然后挂在数据卷并映射端口。
附参考飞机票:https://learnku.com/articles/9200/centos-7-uses-docker-to-build-a-basic-lnmp-environment
但由于我想要一个统一的lnmp环境,所以放弃了这个方法。
方法二:通过Dockerfile,写一些命令,逐步安装各个app及扩展。但由于中途有一些报错,排查了很久,安装过程有些绕,最终放弃。贴出dockerfile代码,大家可以试用一下,如果有能力排除问题,也可以使用。

方法三:在centos中,通过lnmp一键安装包,进行安装。这个方法貌似可以成功,但是耗费时间会根据网络和服务器配置的高低,变得漫长而痛苦。由于本人服务器自己用,所以配置不高,耗费了接近十多个小时,中途没有报错。所以有点哭笑不得。最后还是放弃。
