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：
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。
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。
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. ============================================================================== Welcome to IBM LinuxONE Community Cloud!

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到/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 --2019-05-18 07:12:50-- ftp://ftp.unicamp.br/pub/linuxpatch/s390x/redhat/rhel7.3/docker-17.05.0-ce-rhel7.3-20170523.tar.gz => ‘docker-17.05.0-ce-rhel7.3-20170523.tar.gz’ Resolving ftp.unicamp.br (ftp.unicamp.br)... 143.106.10.149 Connecting to ftp.unicamp.br (ftp.unicamp.br)|143.106.10.149|:21... connected.

之后启动docker daemon：
1 docker daemon -g /local/docker/lib &
[root@virtual-machine ~]# docker daemon -g /local/docker/lib & [1] 21401 [root@virtual-machine ~]# Command "daemon" is deprecated, and will be removed in Docker 17.12. Please run `dockerd` directly.

启动完成后检查一下后台有无docker进程在运行：
1 ps aux | grep docker
[root@virtual-machine ~]# ps aux | grep docker root 21401 0.2 0.6 332008 24708 pts/0 Sl 07:18 0:00 dockerd -g /local/docker/lib root 21410 0.0 0.1 203992 5536 ?

接下来我们要安装docker-compose：
1 yum info python-setuptools 2 # 要先禁用ipv6服务，不然接下来安装pip会非常慢 3 sysctl -w net.ipv6.conf.all.disable_ipv6=1 4 sysctl -w net.ipv6.conf.default.disable_ipv6=1 5 easy_install pip 6 pip install backports.ssl_match_hostname --upgrade --ignore-installed

别忘记验证一下docker-compose是否已经安装：
1 docker-compose version

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 4 docker ps

打开浏览器，直接访问服务器的公网ip就可以看到如图效果：
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 7 environment: 8 WORDPRESS_DB_PASSWORD: example 9 mysql: 10 image: brunswickheads/mariadb-5.5-s390x 11 environment: 12 MYSQL_ROOT_PASSWORD: example
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 version: '2' services: wordpress: image: s390x/wordpress ports: - 8080:80 # 将本地 8080 端口映射到容器的 80 端口 environment: WORDPRESS_DB_PASSWORD: example mysql: image: brunswickheads/mariadb-5.5-s390x environment: MYSQL_ROOT_PASSWORD: example [root@virtual-machine ~]# mkdir wordpress [root@virtual-machine ~]# mv docker-compose.yml wordpress/ [root@virtual-machine ~]# cd wordpress/ [root@virtual-machine wordpress]# ls docker-compose.yml
最后，根据docker-compose.yml中定义的服务启动容器：
1 docker-compose up -d
[root@virtual-machine wordpress]# docker-compose up -d Creating network "wordpress_default" with the default driver Pulling wordpress (s390x/wordpress:latest)... latest: Pulling from s390x/wordpress a0a92d62c165: Pull complete 23fb66856860: Pull complete b38a4e89ae8f: Pull complete 2fa08f5a322d: Pull complete bbf2af7622ca: Pull complete 3dacb3b3a74e: Pull complete 7b49a00cab66: Pull complete 0226e5908d56: Pull complete af4747f0be82: Pull complete caa0c91ea082: Pull complete ecabe806d92c: Pull complete 5d55f6a2617f: Pull complete d0e6cfaadf87: Pull complete 0f9356af4b28: Pull complete e61aa2870c8c: Pull complete 0c6cf289ae6c: Pull complete 22cc2d6c6f63: Pull complete e43117da3e19: Pull complete Digest: sha256:435a9522b41c7e2f5c8dd984a5fde0422ecd87cef67811c269601618e21c5b03 Status: Downloaded newer image for s390x/wordpress:latest Pulling mysql (brunswickheads/mariadb-5.5-s390x:latest)... latest: Pulling from brunswickheads/mariadb-5.5-s390x 67ebcd5ec325: Pull complete a3ed95caeb02: Pull complete 817149461e92: Pull complete 124b1e67e903: Pull complete Digest: sha256:7e67bc8c7d4323dcb3398539f0f819beba4dcae93ded0f72ea6dcf35f39ad10f Status: Downloaded newer image for brunswickheads/mariadb-5.5-s390x:latest Creating wordpress_mysql_1 ...

查看相关容器的状态：
1 docker-compose ps
[root@virtual-machine wordpress]# docker-compose ps Name Command State Ports ------------------------------------------------------------------------------------- wordpress_mysql_1 /docker-entrypoint.sh mysq ... Up 3306/tcp wordpress_wordpress_1 docker-entrypoint.sh apach ... Up 0.0.0.0:8080->80/tcp
登录服务器公网ip:8080，可看到如下界面：
接下来我们要准备MEAN Stack环境。

因为我们之前占用了8080端口，所以需要修改一下配置文件使服务正常启动。
1 cd mean-docker/ 2 vim docker-compose.yml 3 # 把两个8080都改成8081并保存退出 4 vim express-server/Dockerfile 5 # 把8080改成8081，并在文件末尾新建一行添加"ENV PORT 8081"

在mean-docker目录下运行docker-compose up：

然后还要修改index.html里的angular的引用地址。因为某些大家都懂的原因，会导致访问速度非常慢。
