1、下载安装包
wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
2、解压
tar -xvf phantomjs-2.1.1-linux-x86_64.tar.bz2
3、将文件移到/usr/local/目录下
mv /usr/local/src/phantomjs-1.9.7-linux-x86_64 /usr/local/phantomjs
4、软链接
ln -s /usr/local/phantomjs/bin/phantomjs /usr/local/bin/
可能会碰到这个报错：
phantomjs: error while loading shared libraries: libfontconfig.so.1: cannot open shared object file: No such file or directory
这个需要安装libfontconfig1库
apt-get install libfontconfig1
