python使用subprocess查看进程并过滤

来源： https://stackoverflow.com/questions/6780035/how-to-run-ps-cax-grep-something-in-python

将proc1的输出当作proc2的输入来实现

import subprocess

proc1 = subprocess.Popen(["ps","-ef"],stdout=subprocess.PIPE)
proc2 = subprocess.Popen(['grep', 'mysql'], stdin=proc1.stdout,
     stdout=subprocess.PIPE, stderr=subprocess.PIPE)
proc1.stdout.close() # Allow proc1 to receive a SIGPIPE if proc2 exits.
out, err = proc2.communicate()
outline = '{0}'.format(out)

Python一些模块安装方法记录

首先需要安装pip模块，如果yum中没有，则需要用 get-pip.py安装

sudo python get-pip.py 安装

web.py

sudo pip install web.py

mysql.connector

wget http://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-1.0.11.zip 
unzip mysql-connector-python-1.0.11.zip 
cd mysql-connector-python-1.0.11  
sudo python setup.py install

pytds（连接mssql）

1 2	sudo pip install python-tds #sudo pip install bitarray

anjuke(中文转拼音)

sudo pip install pinyin4py

Python2.7安装

这样安装之后不会与之前的python2.6版本有冲突，3.x版本同理

wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz
tar xf Python-2.7.8.tgz
cd Python-2.7.8
./configure --prefix=/usr/local
make && make install

python备份文件到谷歌Drive

原文 https://developers.google.com/drive/v3/web/quickstart/python

安装依赖

pip install --upgrade google-api-python-client

下载认证文件 client_secret.json

谷歌上的步骤:

Use this wizard to create or select a project in the Google Developers Console and automatically turn on the API. Click Continue, then Go to credentials.
On the Add credentials to your project page, click the Cancel button.
At the top of the page, select the OAuth consent screen tab. Select an Email address, enter a Product name if not already set, and click the Save button.
Select the Credentials tab, click the Create credentials button and select OAuth client ID.
Select the application type Other, enter the name "Drive API Quickstart", and click the Create button.
Click OK to dismiss the resulting dialog.
Click the file_download (Download JSON) button to the right of the client ID.
Move this file to your working directory and rename it client_secret.json.

内容大概如下

{"installed":{"client_id":"334720361216-xxxxx.apps.googleusercontent.com","project_id":"analog-fastness-167807","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://accounts.google.com/o/oauth2/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"xxxxxx","redirect_uris":["urn:ietf:wg:oauth:2.0:oob","http://localhost"]}}
