今天群里在给同学投票，有人点50次，于是，研究了一下。

tampermonkey油猴

下面脚本运行不成功, 因为还得处理跨域问题，不怎么熟悉javascript也就没继续研究了，记录一下只是为了说明油猴的入门及调试方法。
另外，在调试的过程中，遇到油猴脚本总不生效，后来在卸载安装最新版本就好了。

Fake Display

在无GUI的ubuntu server上，需要安装一个假的显示器模拟。

apt install -y xvfb
pip3 install pyvirtualdisplay

Others - Install chrome etc

wget -N https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb -P ./
dpkg -i --force-depends ~/google-chrome-stable_current_amd64.deb
apt-get -f install -y
dpkg -i --force-depends ~/google-chrome-stable_current_amd64.deb

wget -N https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar -P ./
xvfb-run java -Dwebdriver.chrome.driver=/home/hua/drivers/chromedriver -jar /home/hua/drivers/selenium-server-standalone-3.141.59.jar
