1.5 tarfile模块使用

用于解压

https://docs.python.org/2/library/tarfile.html?highlight=tarfile#module-tarfile

创建归档文件 tar文件

In [1]: import tarfile

In [2]: tarfile.open(\'/tmp/1.tar\',\'w\')

Out[2]: <tarfile.TarFile at 0x34b6290>

In [3]: t = tarfile.open(\'/tmp/1.tar\',\'w\')

In [4]: t.add(\'/etc/passwd\')

In [5]: t.add(\'/etc/hosts\')

In [6]: t.close()

[root@weifeng08 ~]# cd /tmp

[root@weifeng08 tmp]# ls

1.tar 1.txt etc hsperfdata_root tmp.6xnaKaSM91

[root@weifeng08 tmp]# ll 1.tar

-rw-r--r--. 1 root root 10240 Jan 22 04:39 1.tar

[root@weifeng08 tmp]# tar tf 1.tar

etc/passwd

etc/hosts

解压

In [8]: t = tarfile.open(\'/tmp/1.tar\')

In [9]: t.extractall()

In [10]: t.extractall(path=\'/tmp\')

[root@weifeng08 tmp]# ls

1.tar 1.txt etc hsperfdata_root tmp.6xnaKaSM91

[root@weifeng08 tmp]# cd etc/

[root@weifeng08 etc]# ls

hosts passwd

创建压缩文件

In [12]: t = tarfile.open(\'test.tar.gz\',\'w:gz\')

In [13]: t.add(\'/etc/shadow\')

In [16]: t.add(\'/etc/host.conf\')

In [17]: t.close()

[root@weifeng08 ~]# tar zft test.tar.gz

return True

return False

def pkg_deploy(fn,d):

tar = tarfile.open(fn)

tar.extractall(path=d)

if __name__ == "__main__":

init()

checkLastVersion()

程序用到url 必须开启httpd， lastver, livever 为jenkisn服务器端文件目录

[root@weifeng01 day14]# ls /var/www/download/

wordpress-3.6.tar.gz

[root@weifeng01 day14]# ls /var/www/deploy/

wordpress-3.6

[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

执行脚本后链接文件改成了 3.7

如发现新版本 3.7有bug , 操作回复到旧版本 3.6

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

1.7 版本控制

对版本进行排序

In [7]: from distutils.version import LooseVersion

In [10]: a = LooseVersion(\'3.6\')

In [11]: print a

3.6

In [12]: a = LooseVersion(\'3.7\')

In [13]: print a

3.7

In [14]: a

Out[14]: LooseVersion (\'3.7\')

LooseVersion (\'3.6a\'),

LooseVersion (\'3.7\')]

In [20]: vs.sort()

In [21]: vs

Out[21]:

[LooseVersion (\'3.5.2\'),

LooseVersion (\'3.6\'),

LooseVersion (\'3.6a\'),

LooseVersion (\'3.7\'),

LooseVersion (\'3.11\')]

In [22]: vs[0].vstring

Out[22]: \'3.5.2\'

删除一个目录

In [23]: import shutil

In [24]: shutil.rmtree(\'/tmp/abc\')

最少保留2个版本， lastver,livever的版本不能被删除

[root@weifeng01 ~]# mkdir /var/www/deploy/wordpess-3.8

[root@weifeng01 ~]# ls /var/www/deploy/

wordpess-3.8 wordpress-3.5.2 wordpress-3.6 wordpress-3.7

[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

http://www.fabfile.org/

Fabric 版本

pip install "pycrypto==2.3"

pip install paramiko==1.12.4

pip install fabric==1.8.3

[root@weifeng01 day14]# vim fabfile.py

from fabric.api import run

def host_type():

run(\'uname -s\')

[root@weifeng01 day14]# fab -H localhost host_type

[localhost] Executing task \'host_type\'

[localhost] run: uname -s

[localhost] Login password for \'root\':

[localhost] out: Linux

[localhost] out:

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

[root@weifeng01 day14]# vim fabfile.py

from fabric.api import run

from fabric.api import env

env.user = \'test\'

env.password = \'test\'

env.hosts = [\'localhost\',\'192.168.1.125\']

def host_type():

run(\'uname -s\')

run(\'date\')

再执行命令显示相关信息

[root@weifeng01 day14]# fab host_type

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

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
