fabric自动发布tomcat线上项目

　　现在公司的每个tomcat项目都有测试和生产两个环境，对于经常需要上线的tomcat项目，如用手工更新就非常耗费时间和人力。现用fabric开发了一个自动发布tomcat项目的脚本，该脚本已经在公司使用的非常稳定。

　　fabric自动发布脚本流程如下：

 1 #!/usr/bin/python
 2 #coding=utf-8
 3 from fabric.api import *
 4 from fabric.colors import *
 5 from fabric.context_managers import *
 6 from fabric.contrib.console import confirm
 7 env.user='root'
 8 env.hosts=['192.168.1.10']
 9 env.password='123456789'
10 env.svn_user='userabd'
11 env.svn_password='123456'
12 env.svn_url='svn://192.168.1.20/source/java/project'
13 env.svn_local_path='/data/svn/'
14 env.remote_path='/data/company/project/'
15 @task
16 def package_project():
17     print yellow('开始打包文件')
18     with lcd(env.svn_local_path):
19         local("svn co %s --username=%s --password=%s" %(env.svn_url,env.svn_user,env.svn_password))
20         with lcd("%s'project'" %(env.svn_local_path)):
21             local("mvn clean package -Dmaven.test.skip=true -Ptest -U")
22             with lcd("%s'project/target'" %(env.svn_local_path)):
23                  result=local('ls |grep project.*war$',capture=True)
24                  print yellow('打包文件成功')
25                  print yellow('打包文件为:%s' %(result))
26 @task
27 def put_package():
28     print yellow('开始上传文件')
29     with lcd("%s'project/target'" %(env.svn_local_path)):
30         result=local('ls |grep project.*war$',capture=True)
31     env.local_war_path=env.svn_local_path + 'project/target/' + result
32     with cd("env.remote_path"):
33         put(env.local_war_path,env.remote_path)
34

39         env.local_war_path=env.svn_local_path + 'project/target/' + result
40         env.remote_war_path=env.remote_path + result
41         lmd5=local("md5sum %s" %(env.local_war_path),capture=True ).split(' ')[0]
42         rmd5=run("md5sum %s" %(env.remote_war_path)).split(' ')[0]
43         if lmd5 == rmd5:
44             print green('上传文件成功')
45         else:
46             print red('上传文件失败')
47              
48 @task
49 def unpack_project():
50     print yellow('开始解压war包')
51     with lcd("%s'project/target'" %(env.svn_local_path)):
52         result=local('ls |grep project.*war$',capture=True)
53         with cd(env.remote_path):
54             run("find . ! -name '*war' -a ! -name .|xargs rm -rf")
55             run("unzip %s" %(result))
56              
57  
58 @task
59 def switch_production():
60     print yellow('开始切换生产环境配置文件')
61     with cd(env.remote_path):
62         run('sed -i s/test/production/g WEB-INF/classes/applicationContext.xml')
63  
64  
65 @task
66 def restart_tomcat():
67     print yellow('重启Tomcat进程')
68     run('/usr/local/tomcat/bin/shutdown.sh')
69     run('sleep 10')
70     run('/usr/local/tomcat/bin/startup.sh')
71  
72  
73 @task
74 def production():
75     package_project()
76     put_package()
77     check_task()
78     unpack_project()
79     switch_production()
80     restart_tomcat()

脚本使用方法：fab -f name.py production
