部署PaaS应用（Part1）WordPress & Jenkins Server "部署PaaS应用（Part1）WordPress & Jenkins Server" 下周开始练习PaaS应用部署，这是第一部分。 先电的云计算开发服务平台用户手册-Cloud-paas-v1.2.pdf先后逻辑顺序混乱、错误很多，只看他的文字介绍就可以了。操作步骤需要看我写的文档。 1、基础环境准备 （1）首先应搭建好IaaS基本系统，启动两台云主机，并按照“PaaS基础平台配置.docx”在云主机上安装PaaS基础平台。 （2）编辑安全组default的规则，确保已放行到云主机的所有数据流量。 （3）编辑Windows的DNS服务器配置，删除所有公网DNS服务器，只使用paas节点的DNS服务器192.168.200.101。 （4）使用域名paas.example.com能够访问到Openshift平台。 （5）在控制节点使用与Dashboard中相同的用户新建Git Server云主机，云主机使用固定的IP地址192.168.200.200。 [iyunv@controller ~]# . user1-openrc.sh [iyunv@controller ~]# nova flavor-list +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | ID | Name | Memory_MB | Disk | Ephemeral | Swap |VCPUs | RXTX_Factor | Is_Public | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True | | 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True | | 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True | | 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True | | 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True | | 6 | paas | 2048 | 50 | 0 | | 1 | 1.0 | True | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ [iyunv@controller ~]# nova image-list +--------------------------------------+-------------------+--------+--------+ | ID | Name | Status | Server | +--------------------------------------+-------------------+--------+--------+ | 1014d11f-a36b-49f4-b90f-d56ca21d380b| CentOS-6.5-x86_64 | ACTIVE | | +--------------------------------------+-------------------+--------+--------+ [iyunv@controller ~]# neutron net-list +--------------------------------------+----------+-------------------------------------------------------+ | id | name | subnets | +--------------------------------------+----------+-------------------------------------------------------+ | 02055209-408d-4ecb-a5b6-635138ace958| flat-net | 4cbd55d6-6ca1-491c-ade0-f6bd8526218e 192.168.200.0/24 | +--------------------------------------+----------+-------------------------------------------------------+ [iyunv@controller ~]# nova help boot usage: nova boot[--flavor <flavor>] [--image <image>] [--image-with<key=value>] [--boot-volume <volume_id>] [--snapshot<snapshot_id>] [--num-instances <number>] [--meta <key=value>][--file <dst-path=src-path>] [--key-name <key-name>][--user-data <user-data>] [--availability-zone<availability-zone>] [--security-groups<security-groups>] [--block-device-mapping<dev-name=mapping>] [--block-device key1=value1[,key2=value2...]] [--swap <swap_size>] [--ephemeralsize=<size>[,format=<format>]] [--hint <key=value>] [--nic<net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>] [--config-drive <value>][--poll] <name> Boot a new server.

RSA key fingerprint is90:b6:9e:d0:3e:76:27:ce:34:3b:d6:b4:41:5d:e7:31. Are you sure you want to continueconnecting (yes/no)? yes Warning: Permanently added'192.168.200.200' (RSA) to the list of known hosts. root@192.168.200.200's password: # 输入云主机Git Server的密码000000 id_rsa.pub 100% 391 0.4KB/s 00:00 （6）验证SSH公钥登录 Last login: Sun May 24 02:50:04 2015 from192.168.200.1 [iyunv@codeserver ~]# exit logout Connection to 192.168.200.200 closed. [iyunv@node .ssh]# 3、搭建WordPress博客系统 （1）在Git Server上配置WordPress本地代码源 [iyunv@codeserver ~]# cd [iyunv@codeserver ~]# mkdir gitlocal 使用SFTP将PaaS光盘中paas-xiandan目录中的wordpress-example.tar.gz传到Git Server的/root/gitlocal目录中。 [iyunv@codeserver ~]# cd gitlocal/ [iyunv@codeserver gitlocal]# ls wordpress-example.tar.gz [iyunv@codeserver gitlocal]# tar -zxfwordpress-example.tar.gz [iyunv@codeserver gitlocal]# ls wordpress-example wordpress-example.tar.gz [iyunv@codeserver gitlocal]# git clone--bare wordpress-example wordpress-example.git Initialized empty Git repository in/root/gitlocal/wordpress-example.git/ [iyunv@codeserver gitlocal]# ls wordpress-example wordpress-example.git wordpress-example.tar.gz （2）在Node节点上git clone wordpress-example.git Initialized empty Git repository in/root/wordpress-example/.git/ remote: Counting objects: 4373, done. remote: Compressing objects: 100%(2528/2528), done. remote: Total 4373 (delta 1756), reused4373 (delta 1756) Receiving objects: 100% (4373/4373), 13.12MiB | 21.62 MiB/s, done. Resolving deltas: 100% (1756/1756), done. [iyunv@node ~]# ls anaconda-ks.cfg install.log install.log.syslog wordpress-example （3）在Git Server上安装Web服务器 [iyunv@codeserver gitlocal]# yum installhttpd [iyunv@codeserver gitlocal]# service httpdstart [iyunv@codeserver gitlocal]# chkconfig httpdon （4）使用SFTP将PaaS光盘中paas-xiandan目录中的wordpress-3.9.1.tar.gz 和wordpress-3.9.1.tar.gz.md5复制到Git Server的/var/www/html目录中。在通过Openshift部署WordPress时，需要到这里下载安装文件。 [iyunv@codeserver gitlocal]# cd/var/www/html/ [iyunv@codeserver html]# ls wordpress-3.9.1.tar.gz wordpress-3.9.1.tar.gz.md5 （5）在Node节点上修改wordpress-example.git 源的安装脚本 [iyunv@node ~]# cd [iyunv@node ~]# cd wordpress-example/ [iyunv@node wordpress-example]# ls -a . .. .git .gitignore libs misc .openshift php README README.md [iyunv@node wordpress-example]# cd.openshift/action_hooks/ [iyunv@node action_hooks]# vi build 将以下两处下载地址“http://wordpress.org/”修改为Git Server的IP地址192.168.200.200。 （6）使用git commit -a提交更新，在自动弹出的vi编辑器中输入本次修改的注释信息，保存，git才会提交更新。 [iyunv@node action_hooks]# git commit -a Modified HTTP ServerAddress # Please enter the commit message for yourchanges. Lines starting # with '#' will be ignored, and an emptymessage aborts the commit. # # # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # modified: build # ".git/COMMIT_EDITMSG"12L, 328C written [master 017528f] Modified HTTP ServerAddress Your name and email address were configuredautomatically based on your username and hostname. Please checkthat they are accurate. You can suppress this message by settingthem explicitly: git config --global user.name "Your Name" If the identity used for this commit iswrong, you can fix it with: 1 files changed, 2 insertions(+), 2deletions(-) （7）使用git push推送修改到Git Server [iyunv@node action_hooks]# git push Counting objects: 9, done. Compressing objects: 100% (5/5), done. Writing objects: 100% (5/5), 537 bytes,done. Total 5 (delta 3), reused 0 (delta 0) Toroot@192.168.200.200:/root/gitlocal/wordpress-example.git dc16552..017528f master ->master （8）使用浏览器打开paas.example.com，在设置标签填写Namespace，点击Save保存。 以下为创建好的域名sdcet。 （9）在应用标签创建新应用，点击WordPress。 （10）随意填写公共URL，在源代码处填写GitServer的本地源root@192.168.200.200:/root/gitlocal/wordpress-example.git，点击CreateApplication。 （11）点击“现在不用，继续”。 （12）显示相关数据库的账号和密码。 （13）在新的标签页打开wordpress-sdcet.example.com，出现WordPress安装向导。 （14）填写站点名称、用户名、密码和邮箱地址，点击Install WordPress。 （15）安装完成，点击Log In。 （16）提示证书问题，选择继续访问。输入刚创建的用户名和密码，点击Log In。 （17）以下为WordPress的Dashboard。可以点击中间的“Write your first blog post”发布第一篇博客。 （18）编辑博客内容，编辑完后点击右侧的Publish发布博客。 （19）点击上方的View post查看发布的博客。 （20）以下为普通用户查看到的博客内容。 4、在Git Server上部署RHC工具 RHC是OpenShift 的应用管理工具，可以用于查看在Openshift上部署的应用列表等功能。 （1）在Git Server上编辑/etc/hosts，将paas.example.com解析为paas节点的IP地址。 [iyunv@codeserver ~]# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.200.101 paas.example.com （2）在Git Server上安装Gem 工具 [iyunv@codeserver ~]# yum install rubygems （3）使用SFTP将PaaS光盘中的rhc目录复制到Git Server的/root目录中。 [iyunv@codeserver ~]# cd rhc [iyunv@codeserver rhc]# ls archive-tar-minitar-0.5.2.gem highline-1.6.21.gem net-scp-1.2.1.gem net-ssh-gateway-1.2.0.gem open4-1.3.4.gem commander-4.2.1.gem httpclient-2.5.3.3.gem net-ssh-2.9.1.gem net-ssh-multi-1.2.0.gem rhc-1.32.2.gem （4）安装RHC 工具 [iyunv@codeserver rhc]# gem install --local rhc-1.32.2.gem =========================================================================== If this is your firsttime installing the RHC tools, please run 'rhc setup' =========================================================================== Successfully installed net-ssh-2.9.1 Successfully installed net-scp-1.2.1 Successfully installednet-ssh-gateway-1.2.0 Successfully installed net-ssh-multi-1.2.0 Successfully installedarchive-tar-minitar-0.5.2 Successfully installed highline-1.6.21 Successfully installed commander-4.2.1 Successfully installed httpclient-2.5.3.3 Successfully installed open4-1.3.4 Successfully installed rhc-1.32.2 10 gems installed Installing ri documentation fornet-ssh-2.9.1...
