华工软院IBM LinuxONE Community Cloud云计算实验文档

此博文介绍华南理工大学软件学院“云计算开发与应用”实验课。本人在大二期间选修了这门课,实验课内容是把已有的app部署到云服务器上运行。虽然实验内容很简单(作者大概一个小时就做完了两天的实验内容),但觉得这次实验是我在华工期间做过的为数不多有意义的实验之一,故作此博客记录实验详细过程。此博客以linux环境为准。

实验所需材料与环境配置:

本地环境:Manjaro 18.0.4 (kernel version: x86_64 Linux 5.0.15-1-MANJARO)。需先生成ssh密钥对以便访问服务器。需要安装node.js。

云服务器:IBM LinuxONE Community Cloud。登录/注册地址:https://linuxone.cloud.marist.edu/cloud/#/login

IBM账户(登录/注册地址:https://developer.ibm.com/linuxone/ ),一个自己的github账号。

Day 1:

先到IBM LinuxONE Community Cloud注册账号。因为是人工审核,所以注册流程比想象中要久一些。登录之后就可以看到这样的界面:华工软院IBM LinuxONE Community Cloud云计算实验文档_第1张图片

我们不着急去创建实例,先去右上角的个人用户设置,把本地生成的id_rsa.pub公钥文件上传上去。(什么你告诉我你不会?还不赶紧学?)

新创建的账户最上方不会有Containers的选项,不用管。点击Virtual Server就可以看到下面的界面,右边的Quota显示我们最多只能创建一个vm实例。点击黄色的Create按钮,来创建我们第一个vm实例。华工软院IBM LinuxONE Community Cloud云计算实验文档_第2张图片

点击Create之后稍等一会(可能有点久,要手动刷新一下),就可以看到我们的vm已经准备就绪了。华工软院IBM LinuxONE Community Cloud云计算实验文档_第3张图片

启动terminal,ssh linux1@ip连接到我们的vm实例。

ssh linux1@148.100.244.30
The authenticity of host '148.100.244.30 (148.100.244.30)' can't be established.
ECDSA key fingerprint is SHA256:JPXviVE88jNGDCGvyFFg1iVyQ1fngC6V78pqJCsKCrg.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '148.100.244.30' (ECDSA) to the list of known hosts.

第一个实验是把已有的app(Github Repo: https://github.com/IBM/Cloud-Native-Workloads-on-LinuxONE)部署到云服务器上,通过docker来运行。输入以下内容:

1 sudo su
2 cd ~
3 wget ftp://ftp.unicamp.br/pub/linuxpatch/s390x/redhat/rhel7.3/docker-17.05.0-ce-rhel7.3-20170523.tar.gz
4 tar -xzvf docker-17.05.0-ce-rhel7.3-20170523.tar.gz
5 cp docker-17.05.0-ce-rhel7.3-20170523/docker* /usr/bin/

这里直接cp/usr/bin就好,因为/usr/local/bin不在PATH环境变量里。效果如下所示。

[linux1@virtual-machine ~]$ sudo su
[root@virtual-machine linux1]# cd ~
[root@virtual-machine ~]# wget ftp://ftp.unicamp.br/pub/linuxpatch/s390x/redhat/rhel7.3/docker-17.05.0-ce-rhel7.3-20170523.tar.gz

接下来我们要手动拉取websphere-liberty镜像到本地,后台运行docker并指定端口映射规则:

1 docker image pull s390x/websphere-liberty:webProfile7
2 docker images
3 docker run -d -p 80:9080 -p 443:9443 s390x/websphere-liberty:webProfile7

接下来我们要安装并运行WorkPress:

1 alias vim='vi'
2 source ~/.bashrc
3 vim docker-compose.yml

把以下内容复制到新的文件中去:

 1 version: '2'
 2 services:
 3   wordpress:
 4     image: s390x/wordpress
 5     ports:
 6       - 8080:80 # 将本地 8080 端口映射到容器的 80 端口

创建新的wordpress目录方便整理:

1 mkdir wordpress
2 mv docker-compose.yml wordpress/
3 cd wordpress/
4 ls
[root@virtual-machine ~]# alias vim='vi'
[root@virtual-machine ~]# source ~/.bashrc
[root@virtual-machine ~]# vim docker-compose.yml
[root@virtual-machine ~]# cat docker-compose.yml
