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
35 @task
36 def check_task():
37 with lcd("%s'project/target'" %(env.svn_local_path)):
38 result=local('ls |grep project.*war$',capture=True)
39 env.local_war_path=env.svn_local_path + 'project/target/' + result
40 env.remote_war_path=env.remote_path + result
41 lmd5=local("md5sum %s" %(env.local_war_path),capture=True ).split(' ')[0]
42 rmd5=run("md5sum %s" %(env.remote_war_path)).split(' ')[0]
43 if lmd5 == rmd5:
44 print green('上传文件成功')
45 else:
46 print red('上传文件失败')
47
48 @task
49 def unpack_project():
50 print yellow('开始解压war包')
51 with lcd("%s'project/target'" %(env.svn_local_path)):
52 result=local('ls |grep project.*war$',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
