[root@weifeng01 day14]# du -sh /var/www/deploy/wordpress-3.6/
43M /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
[root@weifeng01 day14]# ls /var/www/deploy/
wordpress-3.6
[root@weifeng01 day14]# curl http://192.168.1.125/deploy/livever
3.6
[root@weifeng01 day14]# curl http://192.168.1.125/deploy/lastver
3.6
[root@weifeng01 day14]# cd /var/www/html/
[root@weifeng01 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/p.txt@
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

jenkins里 重新构建一个3.6 的 livever , 再执行脚本 deploy.py (实际环境可以 cron) , 版本可回滚到 3.6

[root@weifeng01 day14]# python deploy2.py

[root@weifeng01 ~]# ls /var/www/deploy/
wordpess-3.8 wordpress-3.5.2 wordpress-3.7
删除了版本 3.6
文件锁 ： deploy.py 脚本执行时，进行锁定
脚本中增加 函数
def lockfile(f):
if os.path.exists(f):
print "%s is running...." % __file__
sys.exit()
with open(f, ‘w‘) as fd:
fd.write(str(os.getpid()))
def unlockfile(f):
if os.path.exists(f):
os.remove(f)
if __name__ == "__main__":
lockfile(‘/tmp/deploy.lock‘)
init()
checkLastVersion()
checkLiveVersion()
clean()
import time
time.sleep(60)
unlockfile(‘/tmp/deploy.lock‘)
执行结果：
[root@weifeng01 day14]# python deploy2.py
另外一台终端操作
[root@weifeng01 day14]# python deploy2.py
deploy2.py is running....
增加crontab
[root@weifeng01 day14]# crontab -e
* * * * * python /root/day14/deploy2.py
每分钟执行一次
1.9 使用fabirc状态检查

Fabric 版本
pip install "pycrypto==2.3"

创建一个test 用户
[root@weifeng01 day14]# useradd test
[root@weifeng01 day14]# passwd test
Changing password for user test.
New password:
BAD PASSWORD: it is too short
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
You have new mail in /var/spool/mail/root
[root@weifeng01 day14]# grep test /etc/passwd
badtest:x:501:501::/home/badtest:/bin/bash
test:x:502:502::/home/test:/bin/bash
增加用户， 主机等信息

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
[root@weifeng01 day14]# cd /var/www/html/
You have new mail in /var/spool/mail/root
[root@weifeng01 html]# ls
current deploy zabbix
[root@weifeng01 html]# mkdir scripts
[root@weifeng01 html]# ls
current deploy scripts zabbix
创建 scripts 文件夹
[root@weifeng01 html]# cp /root/day14/fabfile.py .
[root@weifeng01 html]# ls
current deploy fabfile.py scripts zabbix
[root@weifeng01 html]# vim fabfile.py
修改脚本

Finished: SUCCESS
~
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
[root@weifeng01 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
[root@weifeng01 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
[root@weifeng01 html]# ls /var/www/html/ -l
total 20
lrwxrwxrwx 1 root root 29 Jan 20 15:05 current -> /var/www/deploy/wordpress-4.4
已经进行更改
[root@weifeng01 html]# curl http://192.168.1.125/deploy/livever
4.4
You have new mail in /var/spool/mail/root
[root@weifeng01 html]# curl http://192.168.1.125/deploy/lastver
