[[email protected] day14]# du -sh /var/www/deploy/wordpress-3.6/

将文件解压分发到 deploy 目录下
1.6 使用符号链接发布应用
[[email protected] day14]# ls /var/www/deploy/
wordpress-3.6
[[email protected] day14]# curl http://192.168.1.125/deploy/livever
3.6
[[email protected] day14]# curl http://192.168.1.125/deploy/lastver
3.6
[[email protected] day14]# cd /var/www/html/
[[email protected] html]# ls
deploy zabbix
使用符合链接将文件链接到 html目录下
符合链接的用法:
In [18]: import os
In [19]: os.symlink(‘/etc/passwd‘, ‘/tmp/p.txt‘)
In [20]: ls /tmp/p.txt
/tmp/[email protected]
In [21]: ls -l /tmp/p.txt
lrwxrwxrwx 1 root root 11 Jan 22 06:36 /tmp/p.txt -> /etc/passwd
In [22]: os.readlink(‘/tmp/p.txt‘) python下 读链接文件
Out[22]: ‘/etc/passwd‘
In [23]: os.unlink(‘/tmp/p.txt‘) 取消链接文件

将farbric 函数用到jenkins, 执行有提示
Jenkins 新建 Item名称 wordpress-check
选中 构建一个自由风格的软件项目
不需要参数,只需要构建 shell 脚本
[[email protected] day14]# cd /var/www/html/
You have new mail in /var/spool/mail/root
[[email protected] html]# ls
current deploy zabbix
[[email protected] html]# mkdir scripts
[[email protected] html]# ls
current deploy scripts zabbix
创建 scripts 文件夹
[[email protected] html]# cp /root/day14/fabfile.py .
[[email protected] html]# ls
current deploy fabfile.py scripts zabbix
[[email protected] html]# vim fabfile.py
修改脚本

2.0 整体测试
先构建项目 wordpress-build
如 4.4
构建项目会保存到 lastver
控制台输出
Finished: SUCCESS后
脚本会cron自动执行
[[email protected] html]# ls /var/www/download/
wordpress-3.7.tar.gz wordpress-3.8.tar.gz wordpress-4.4.tar.gz
You have new mail in /var/spool/mail/root
[[email protected] html]# ls /var/www/deploy/
wordpess-3.8 wordpress-3.7 wordpress-4.4
下一步检测
wordpress-check 构建项目 控制台输出 success
再执行 wordpress-live
显示 控制台输出 success
