CloudFoundry in 1 Box簡介：PCF－Dev篇

Pivotal Web Service主管工程師 產品經理 吳疆

在《CloudFoundry in 1 Box簡介：Bosh－lite篇》我們介紹了Bosh－lite的架構和部署。在本篇中，我們將詳細描述另一個CloudFoundry in 1 Box解決方案PCF－Dev。

1. PCF－dev簡介

PCF是Pivotal發行的Cloud Foundry商業版，PCF－Dev原名MicroPCF，是Pivotal為PCF的應用開發人員準備的一款App單虛擬機版的CloudFoundry。但是，麻雀雖小，五臟俱全。PCF－Dev雖然可以在僅僅一臺虛擬式上即可運行，但是卻包含了cloud foundry完整的技術棧。下圖展示了PCF－Dev的架構

在PCF－Dev中，除了包含了完整的Cloud Foundry，還包含了下列Cloud Foundry Service

• MySQL

• Redis

• RabbitMQ

和一系列Buildpack

• Java

• Ruby

• Python

• Golang

• Static file

• Binary

PCF－Dev不僅功能強大，使用起來卻是異常簡便。下面我們就來一步一步搭建一個PCF－Dev環境。

2. 環境準備

筆者采用的事Cent OS 7.2作為宿主機的操作系統，VirtualBox為虛擬機平臺

2.1 安裝以來的軟件包

# rpm -Uvh http://mirror.pnl.gov/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
# yum install -y vim git screen kernel* libX11 qt SDL SDL-devel libxml2-devel \
               libvpx libpng libXt libXmu libxslt libxslt-devel openssl \ 
               openssl-devel libXcursor libXinerama qt qt-devel wget gcc unzip ntpdate net-tools

2.2 安裝Ruby環境

筆者使用rbenv來安裝和管理ruby

# git clone git://github.com/sstephenson/rbenv.git $HOME/.rbenv
# git clone https://github.com/sstephenson/ruby-build.git $HOME/.rbenv/plugins/ruby-build 
# echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile 
# echo 'eval "$(rbenv init -)"' >> ~/.bash_profile 
# source ~/.bash_profile 
# rbenv install 2.3.0 
# rbenv global 2.1.3
# gem install bundle
# gem install nokogiri — --use-system-libraries

2.3安裝Vagrant

# wget https://releases.hashicorp.com/vagrant/1.8.1/vagrant_1.8.1_x86_64.rpm
# rpm -Uvh vagrant_1.8.1_x86_64.rpm

驗證vagrant

# vagrant --version
Vagrant 1.8.1

2.4 安裝VirtualBox

# wget http://download.virtualbox.org/virtualbox/5.0.16/VirtualBox-5.0-5.0.16_105871_el7-1.x86_64.rpm
# #安裝virtualbox時需要linux kernel的源代碼，設置KERN_DIR環境變量指示kernel源代碼路徑
# export KERN_DIR=/usr/src/kernels/<your kernel dir>
# rpm -Uvh VirtualBox-5.0-5.0.16_105871_el7-1.x86_64.rpm

驗證virtualbox是否安裝成功

# VBoxManage --version
5.0.16r105871

3. 部署PCF－Dev

3.1 從pivotal network下載PcF－dev

Pivotal Network地址：http://network.pivotal.io

3.2 解壓pcf－dev

3.3 啟動pcf－dev

＃ cd <pcf-dev>
＃ ./start-osx #在linux也可以正常工作

3.4 查看PCF－dev component

＃ cd <pcf-dev>
＃ vagrant ssh ##登陸pcf－dev虛擬機

＃ 登陸之后的pcf－dev虛擬機
$ sudo -i
＃ monit summary
root@agent-id-pcfdev-0:~# monit summary

System 'system_localhost'           running

啟動后的PCF-Dev虛擬機配置了兩塊網卡,一塊用來連接CloudFoundry網絡，使用10.0.2.15/24；一塊用來和宿主機通信，使用IP 192.168.11.11

如果設有http https proxy，需要執行如下步驟

export no_proxy=192.168.11.11,local.pcfdev.io

至此，PCF-Dev環境準備完畢。

4. 部署app到PCF－Dev

4.1 安裝CF CLI

#rpm -Uvh https://s3.amazonaws.com/go-cli/releases/v6.16.1/cf-cli-installer_6.16.1_x86-64.rpm

4.2 cf target

PCF－Dev默認的域名為local.pcfdev.io, *.local.pcfdev.io會被解析到192.168.11.11

＃ ping xyz.local.pcfdev.io
