【URLOS应用开发基础】10分钟制作nginx静态网站环境应用
URLOS开发者功能已上线有一段时间了,目前通过部分开发者的使用体验来看,不得不说URLOS在服务器软件开发效率方面确实有着得天独厚的优势,凭借docker容器技术与其良好的应用生态环境,URLOS必将迅速成为软件开发者的新宠儿。
本篇内容以入门为主,通过制作一个简单的静态网站环境应用,让新晋开发者能在短时间内对URLOS的开发流程有所认识。
URLOS基于docker容器技术,因此在应用开发过程中我们离不开docker的相关命令,对docker还不太了解的朋友,可以先大致了解一下docker的相关内容,本篇不做详细讨论。
URLOS应用开发的基本流程
本篇目标是制作nginx静态网站环境,那么我们需要做的内容包括:运行一个基础镜像,在此镜像基础上安装nginx,设置网站根目录,打包并上传新镜像,通过URLOS添加新应用,发布并导出应用。
制作nginx静态网站环境
一、拉取Alpine基础镜像
为什么选择Alpine作为基础镜像?因为Alpine的文件体积小啊,基础镜像只有5.53MB,相比ubuntu镜像的88.9MB要小十几倍。
使用docker pull alpine
命令拉取alpine镜像:
root@ubuntu:~# docker pull alpine Using default tag: latest latest: Pulling from library/alpine bdf0201b3a05: Pull complete Digest: sha256:28ef97b8686a0b5399129e9b763d5b7e5ff03576aa5580d6f4182a49c5fe1913 Status: Downloaded newer image for alpine:latest root@ubuntu:~#
然后使用docker images
命令查看镜像:
root@ubuntu:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE urlos/urlos latest 4810506f7202 12 hours ago 447MB alpine latest cdf98d1859c1 2 weeks ago 5.53MB root@ubuntu:~#
二、更新镜像,安装nginx
运行Alpine镜像并进入容器内部:
root@ubuntu:~# docker run -it alpine sh / #
更换更新源:
/ # vi /etc/apk/repositories
将其中内容换成阿里云的源
/ # cat /etc/apk/repositories https://mirrors.aliyun.com/alpine/v3.6/main/ https://mirrors.aliyun.com/alpine/v3.6/community/ / #
使用apk update
执行更新:
/ # apk update fetch https://mirrors.aliyun.com/alpine/v3.6/main/x86_64/APKINDEX.tar.gz fetch https://mirrors.aliyun.com/alpine/v3.6/community/x86_64/APKINDEX.tar.gz v3.6.5-25-g77eea063d8 [https://mirrors.aliyun.com/alpine/v3.6/main/] v3.6.5-18-gfdfe1f6192 [https://mirrors.aliyun.com/alpine/v3.6/community/] OK: 8453 distinct packages available / #
使用apk add nginx
安装nginx:
/ # apk add nginx (1/4) Installing libressl2.5-libcrypto (2.5.5-r2) (2/4) Installing pcre (8.41-r0) (3/4) Installing libressl2.5-libssl (2.5.5-r2) (4/4) Installing nginx (1.12.2-r2) Executing nginx-1.12.2-r2.pre-install Executing busybox-1.29.3-r10.trigger OK: 9 MiB in 18 packages / #
保护pid:
/ # cd /run/ /run # mkdir nginx
添加网站根目录:
/ # mkdir -p /data/www/
修改nginx配置文件:
/data/www # vi /etc/nginx/conf.d/default.conf
/data/www # cat /etc/nginx/conf.d/default.conf # This is a default site configuration which will simply return 404, preventing # chance access to any other virtualhost. server { listen 80 default_server; listen [::]:80 default_server; location / { index index.html; root /data/www; } # You may need this to prevent return 404 recursion. location = /404.html { internal; } } /data/www #
测试nginx:
/data/www # nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
OK,nginx配置完成!
使用exit
退出容器,准备打包镜像。
/data/www # exit root@ubuntu:~#
三、打包镜像
使用命令docker ps -a
查看所有容器:
root@ubuntu:~# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a5249fa1d7ec alpine "sh" 35 minutes ago Exited (0) 2 minutes ago youthful_heisenberg 1502c4163c2c urlos/urlos:latest "sh /entrypoint.sh" 2 hours ago Up 2 hours 0.0.0.0:9001->9001/tcp, 0.0.0.0:9966->9966/tcp, 0.0.0.0:9968->9968/tcp urlos root@ubuntu:~#
使用docker commit
命令打包镜像,然后使用docker images
命令查看镜像:
root@ubuntu:~# docker commit a5249fa1d7ec yeqing112/alpine-nginx:0.0.1 sha256:4730bd89ee3e9408f0ba29c5c80ad0a13600b82de565bbc49f3d4ec8585902c4 root@ubuntu:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE yeqing112/alpine-nginx 0.0.1 4730bd89ee3e 13 seconds ago 10MB urlos/urlos latest 4810506f7202 13 hours ago 447MB alpine latest cdf98d1859c1 2 weeks ago 5.53MB root@ubuntu:~#
OK,我们成功制作了一个名称为yeqing112/alpine-nginx的新镜像。
四、上传镜像
首先使用命令docker login
进行登录,如果没有docker账号,请到docker官网注册:
root@ubuntu:~# docker login Authenticating with existing credentials... WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded root@ubuntu:~#
使用docker push
命令上传镜像:
root@ubuntu:~# docker push yeqing112/alpine-nginx:0.0.1 The push refers to repository [docker.io/yeqing112/alpine-nginx] bbe56e36ea7a: Pushed a464c54f93a9: Mounted from library/alpine 0.0.1: digest: sha256:94c5f0c38a3de543cde52791b3daff3fdc8001e99bf58bb08230b2cab3e062a3 size: 739 root@ubuntu:~#
打开docker镜像仓库可以看到我们上传的镜像了
镜像上传成功后,访问http://主机ip:9968
登录URLOS主控,我们将在这里面进行应用的添加(没有安装URLOS的,百度搜索URLOS,到官网查看安装方法)。
五、制作URLOS应用
登录urlos主控后,我们先检查URLOS版本和模式是否正确,制作应用我们需要使用URLOS付费版本,这里我使用了URLOS标准版,并且需要将模式改为DEV(开发模式),具体修改方法到URLOS官网查看。
添加镜像
添加应用
我在这一步要偷偷懒,直接复制一个已有应用,然后稍作修改。那我们选择复制什么应用呢?其实官方有一个静态网站的应用,直接复制过来修改即可。在应用管理列表中搜索nginx
关键词,找到系统自带的静态网站应用:
点击更多
按钮,在弹出菜单中选择复制应用
:
以下截图中标红的内容是必须修改的,其他内容的修改视个人情况而定。
基本信息:
这里我们就修改应用名称和镜像即可。
在当前项目中,其他选项我们不需要去修改,因为那些内容跟我们的需求是一样的。
点击提交
按钮,OK,我们的应用制作完成了!啊?这么快?没错!就是这么快。
然后我们通过这个新应用快速的部署一个网站试试,点击更多
,弹出菜单中选择创建服务
部署完成浏览器打开网站,静态网站成功运行!
我们还可以将这个静态网站应用导出来,转给其他用户导入使用:
导出的是文本文件,体积非常小:
导入应用时,只需将文本中的内容复制黏贴即可:
以下是这个应用导出的文本内容,仅供大家测试:
