awk 计算一列的和

awk '{sum += $10};END {print sum}'

例如想计算nginx日志中206下载总数据和，则用
cat xxx.access.log|grep " 206 " |awk '{sum += $10};END {print sum}'

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

安装RemixOS到PC

！一定要用UEFI方式启动，前提是64位的

下载镜像

https://www.fosshub.com/Remix-OS.html

刻录到U盘

解压之后有一个iso文件一个exe文件，推荐用ultraiso安装（用那个exe会把U盘分成三个区。。。有病吗？）

修改参数

U盘开机启动之后，选择”Resident/Guest mode”，按TAB键或e键，在命令最后添加”INSTALL=2”，删掉”USB_DATA_PARTITION=1”

接下来系统会安装到硬盘上。

用Python抓取王垠的博客

直接上代码（由于他博客是异步的，所以我们要用mechanize）

剩下的自己该干嘛干嘛吧

最靠谱的Tomcat日志切割教程

强大的logrotate

更多logrotate的说明见 http://www.linuxcommand.org/man_pages/logrotate8.html

或者这里 https://linux.cn/article-4126-1.html

在/etc/logrotate.d/tomcat里写入下面的内容

/data/logs/logpath/catalina-daemon.out {
        daily
        rotate 3
        size 100M
        nocompress
        notifempty
        missingok
        copytruncate
        create 0600 root root
}

测试

logrotate --force /etc/logrotate.d/tomcat.conf

查看是否有一个/data/logs/logpath/catalina-daemon.out.1生成

为什么不用cronolog?

很简单，cronolog对jsvc启动的tomcat不友好

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"]}}
