用持续集成工具Travis进行构建和部署
摘要：本文简单说明了如何使用持续集成工具Travis进行构建和部署的过程。
1. 概述
持续集成(Continuous Integration)是软件开发过程中的重要环节，不论是在开发环境，还是生产环境，其好处都是可以让团队尽快得到反馈，从而尽早发现和解决问题，不要等到用户来报告问题，影响产品和团队的声誉。越早越快地发现和解决问题，成本越低，这也是敏捷开发的基本目的之一。
持续集成的工具有不少，著名的有CruiseControl、JetBrains的TeamCity、微软的Team Foundation Server。本文讲的是另外一个相对轻巧的持续集成工具Travis。这个工具的不同之处是，它已经搭建好了，有自己的环境，省去了你用自己的服务器安装、配置的麻烦。如果你的项目是开源的，只需要在https://travis-ci.org/上用Github的账号注册就可以免费使用了;如果不是开源的项目，就要收费了，要用https://travis-ci.com/，具体的收费标准可以参考https://travis-ci.com/plans。下面只讲述https://travis-ci.org/的使用和配置，因为https://travis-ci.com/我也没用过，不过估计收费的功能应该更多更好一些。
2. 选择项目
在https://travis-ci.org/注册了账号之后，在Github账号下的项目会自动出现在这里，可以选择哪个项目要用Travis来做持续集成，缺省情况下所有项目都是不做持续集成的。如下图所示，

3个项目中，只有最后一个项目是要做持续集成的，其它都不做持续集成。你还可以进一步配置，一个项目中的哪个或哪几个分支要做持续集成，这在后面会讲到。
3. 配置
持续集成的配置，必须通过位于项目根目录下的.travis.yml文件来进行，完整的文档可以见附录中的参考资料[1]。
首先，要选择项目的语言。写此文时Travis支持15种编程语言，象常用的Java、C、C++、JavasScript (with Node.js)、Objective-C、PHP、Python和Ruby都在支持之列。我的docs项目是个文档项目，使用Sphinx，所以语言就选择了Python 2.7，和我的开发环境保持一致。所以，我的.travis.yml文件开始的部分是这样的：
language: python
python:
- "2.7"
其次，要安装一些相关的软件包，可以在install命令中进行安装，在安装之前必要的依赖包可以在before_install中进行，所以.travis.yml文件中相应的部分为：
# Use this to prepare the system to install prerequisites or dependencies
before_install: "sudo apt-get update" # command to install dependencies
install: "pip install -q -r requirements.txt --use-mirrors"
而要安装的包是在requirements.txt中指定的，其内容如下：
Sphinx==1.2
sphinxcontrib-phpdomain
安装的Sphinx版本为1.2，最新的Sphinx 1.3在构建的时候会碰到错误，所以用旧一些的版本。sphinxcontrib-phpdomain是用来扩展Sphinx的。
4. 构建
构建在script命令中指定。在我的这个项目中，这是最简单的，我参考的资料也是最简单的，见[2]。.travis.yml文件中相应的部分为：
# command to build
script: make html
这里执行的命令，如果返回值是0就算成功，否则就算失败，这是Unix返回值的标准。
前面提到限制项目的分支，可以作如下配置：
# whitelist
branches:
only:
- mybranch
这就是，只有mybranch这个分支要做持续集成，也可以用多行指定多个分支。
这时，就可以提交.travis.yml，并推送到Github服务器，Travis就会自动检查到这个项目的变化，自动启动一个虚拟机，来进行持续集成。
可以看到，这是一种按需、即时的方式，和自己安装、配置服务器进行持续集成的方式相比，更为节省资源，更能实现更好的效果。
5. 部署
部署稍微麻烦一些，因为要涉及到具体的服务器配置。相关的文档见参考资料[3]。
首先，Travis不支持sftp，详见考资料[4]，这比较遗憾。为保证安全，我打算用ftps。
5.1 安装、配置服务器上的ftp
先要在服务器(Ubuntu 12.04)上安装、配置vsftpd，请看参考资料[7]和[8]。
但使用的是普通用户，不是超级管理员，也没有sudo的权限。要赋予该用户sudo的权限，可以把该用户加入sudo用户组。见参考资料[5]和[6]，使用超级管理员root，执行如下命令：
# sudo usermod -a -G sudo myusername
这就把用户myusername加入了sudo用户组，就可以使用sudo来执行超级管理员才能的一些管理任务了，以下命令都是该普通用户执行的。
下面安装vsftpd，执行如下命令：
$ sudo apt-get install vsftpd
安装完毕后，配置vsftpd，这都是通过修改/etc/vsftpd.conf完成的。先禁止匿名用户：
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
再允许服务器的本地用户(即myusername等)使用ftp：
# Uncomment this to allow local users to log in.
local_enable=YES
因为是要上传构建得到的文件到服务器，所以还要开启写入操作：
# Uncomment this to enable any form of FTP write command.
write_enable=YES
ftp使用端口21作为控制通道，供用户接入、登录、登出等交换控制信息使用。另外，还需要数据通道，传输上载、下载的数据。在主动模式下，数据通道缺省为端口20，这个我没有改。在被动模式下，需要自行设置一组端口：
# These two options set the ports for passive mode.
pasv_min_port=6789
pasv_max_port=6890
最后，需要在防火墙的设置中开启这些涉及的端口，20、21、6789-6890，这是朋友帮助做的，我也不知道具体如何操作的。
最后，可用浏览器访问ftp服务器，并上传、下载文件，验证以上配置正确。
5.2 配置Travis使用ftp部署
Travis的各个执行环节中，还有一个环节after_success，这是在script命令执行成功之后执行的。部署就是在这个环节进行的，添加如下配置到.travis.yml文件中：
after_success:
"find ./make/output -type f -exec curl --ftp-create-dirs -u $FTP_USER:$FTP_PASSWORD -T {} ftp://123.45.67.89/myproject/{} \\;"
这个命令由find找出要部署的文件，然后交给curl，上传到服务器上。其中，./make/output为构建的输出目录，123.45.67.89是服务器的IP地址，/myproject/为服务器上要部署的目录。$FTP_USER和$FTP_PASSWORD是Travis持续集成的环境变量，需要在.travis.yml文件中单独设置：
env:
global:
- "FTP_USER=myusername"
- "FTP_PASSWORD=mypassword"
到此，一个基本的包括构建和部署的Travis持续集成环境就算是配置好了。每次这个项目推送到Github库的指定分支，Travis就是自动检测到，自动进行构建，构建成功后就会自动部署到指定的服务器上。
完整的.travis.yml文件如下：
language: python
python:
- "2.7" env:
global:
- "FTP_USER=myusername"
- "FTP_PASSWORD=mypassword" # whitelist
branches:
only:
- mybranch # Use this to prepare the system to install prerequisites or dependencies
before_install: "sudo apt-get update" # command to install dependencies
install: "pip install -q -r requirements.txt --use-mirrors" # command to build
script: make html after_success:
"find ./make/output -type f -exec curl --ftp-create-dirs -u $FTP_USER:$FTP_PASSWORD -T {} ftp://123.45.67.89/myproject/{} \\;"
6. 结语
本文只是介绍了利用Travis进行持续集成的简单配置，还有一些问题没有说明或解决，比如：
- ftp不够安全，是否可以使用ftps来加强安全性？
- Travis的配置文件中，ftp的用户名和密码是明文，是可以加密的。
有兴趣的朋友，可以自己研究Travis的文档。
