Git

发布系统准备工作

一、Git版本管理

很多公司在使用git的tag进行版本的管理。

git tag -n                          查看本地Tag
git tag -l 'v1.4.2.*'               查看本地Tag，模糊匹配
git show v1.0                       查看
 
git tag -a v1.0 -m '版本介绍'        本地创建Tag
git tag -d v1.0                     删除Tag
git checkout v.10                   切换tag
 
git push origin  --tags             推送本地tag到远程
git pull origin  --tags             获取远程tag
 
git clone -b v0.10  http://...      指定版本克隆代码

二、Python操作git

三、Python解压缩文件

在py2和py3中对文件进行解压缩稍有不同。

• shutil 模块【压缩支持py2和py3，解压只支持py3】
• tarfile / zipfile模块【支持py2和py3】

import shutil

# 文件压缩
"""
ret = shutil.make_archive(
    base_name="code/www",  # 压缩包文件路劲
    format='zip',  # “zip”, “tar”
    root_dir='code/fuck'  # 被压缩的文件件
)
print(ret)
"""

# 解压文件
"""
shutil._unpack_zipfile('code/www.zip', 'code/new')
shutil._unpack_tarfile('code/www.tar', 'code/new')
"""

shutil模块

import zipfile

# 压缩
z = zipfile.ZipFile('laxi.zip', 'w')
z.write('a.log')
z.write('data.data')
z.close()

# 解压
z = zipfile.ZipFile('laxi.zip', 'r')
z.extractall()
z.close()

zipfile模块

import tarfile

# 压缩
tar = tarfile.open('your.tar', 'w')
tar.add('utils/codes/luffycity/a1.py')
tar.add('utils/codes/luffycity/a3.py')
tar.close()

# 解压
tar = tarfile.TarFile('code/www.tar', 'r')
tar.extractall(path='/code/x1/')  # 可设置解压地址
tar.close()

tarfile模块

四、执行本地命令

import subprocess
 
result = subprocess.check_output('ls -l', cwd='/Users/wupeiqi/PycharmProjects', shell=True)
print(result.decode('utf-8'), type(result))

 五、Paramiko执行远程操作

import paramiko
 
 
class SSHProxy(object):
 
    def __init__(self, hostname, port, username, private_key_path):
        self.hostname = hostname
        self.port = port
        self.username = username
        self.private_key_path = private_key_path
 
        self.transport = None
 
    def open(self):
        private_key = paramiko.RSAKey.from_private_key_file(self.private_key_path)
        self.transport = paramiko.Transport((self.hostname, self.port))
        self.transport.connect(username=self.username, pkey=private_key)
 
    def close(self):
        self.transport.close()
 
    def command(self, cmd):
        ssh = paramiko.SSHClient()
        ssh._transport = self.transport
        stdin, stdout, stderr = ssh.exec_command(cmd)
        result = stdout.read()
        #ssh.close()
        return result
 
    def upload(self, local_path, remote_path):
        sftp = paramiko.SFTPClient.from_transport(self.transport)
        sftp.put(local_path, remote_path)
        sftp.close()
 
    def __enter__(self):
        self.open()
        return self
 
    def __exit__(self, exc_type, exc_val, exc_tb):
        self.close()
 
 
if __name__ == '__main__':
    with SSHProxy('10.211.55.25', 22, 'root', '/Users/wupeiqi/.ssh/id_rsa') as ssh:
        # v1 = ssh.command('sudo ifconfig')
        # print(v1)
        ssh.upload('your.tar', '/data/your.tar')

六、杀进程 

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import os
import signal
import subprocess
 
output = subprocess.check_output("pgrep -f python", shell=True)
pid_list = map(int, output.split())
for pid in pid_list:
    os.kill(pid, signal.SIGKILL)

其他

#!/usr/bin/env python
# -*- coding:utf-8 -*-
