这是一个系列，用python3写了一个终端下登陆校园网的脚本，因为Centos6.5服务器没有图像界面，所以有这个需求

默认python版本是2，所以需要配置一下Centos的python版本

centos本地编译安装python3

本地上传python3的压缩包

下载Python 3.x，地址：https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

解压命令：tar zxvf Python-3.6.5.tgz

移动命令：mv Python-3.6.5 /usr/local

设置安装目录：./configure –prefix=/usr/local/python3
目的就是把python的安装目录指定一下，这样的话，里面的一些bin目录、lib目录就都会存放在这个目录下面。如果不指定这个安装目录的话，最后python的安装文件将分散到linux的默认目录，不在一块。我们指定安装目录，以后卸载的话直接删除目录就可以干净卸载了。

开始编译：make&&make install

添加环境变量（可以在任意位置执行python3）：
echo PATH=’/usr/local/python/bin/:$PATH’ >> /etc/profile
source /etc/profile

至此，centos6.5就可以在任意目录下执行python3命令了

CentOS本地安装PhantomJS

下载Linux压缩包：https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2

建议先进入其官方网站再去下载，否则速度奇慢无比，官网：
http://phantomjs.org/download.html

解压：tar -jxvf phantomjs-2.1.1-linux-x86_64.tar.bz2
移动：mv phantomjs-2.1.1-linux-x86_64 /usr/local
添加环境变量：
echo PATH=’/usr/local/phantomjs-2.1.1-linux-x86_64/bin/:$PATH’ >> /etc/profile
source /etc/profile

接下来就是我的校园网登陆脚本了
