Categories 学习笔记 
# 安装依赖软件
yum -y install wget fontconfig

# 下载PhantomJS 64位/32位
wget -P /tmp/ https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
wget -P /tmp/ https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-i686.tar.bz2

# 解压 64位/32位
tar xjf /tmp/phantomjs-2.1.1-linux-x86_64.tar.bz2 -C /usr/local/
tar xjf /tmp/phantomjs-2.1.1-linux-i686.tar.bz2 -C /usr/local/

# 重命名 64位/32位
mv /usr/local/phantomjs-2.1.1-linux-x86_64 /usr/local/phantomjs
mv /usr/local/phantomjs-2.1.1-linux-i686 /usr/local/phantomjs

# 建立软链接
ln -s /usr/local/phantomjs/bin/phantomjs /usr/bin/

在终端执行phantomjs命令，如果跟我下图的结果一样就表示安装成功了。
