centos6自带python是2.6,正巧需要给四五台机器升级python,于是干脆写了如下脚本
直接使用:
wget -N --no-check-certificate https://down.cangshui.net/-mysh/pythoninstall/centos6uppython.sh && chmod +x centos6uppython.sh && bash centos6uppython.sh
脚本预览
echo "请输入序号选择你要干啥:
输入1. 升级到Python 2.7.9
输入2. 安装python3,,并与Python2共存
输入99. 直接删除python2.7和python3__危险!有可能使Yum将无法使用,知道vi /usr/bin/yum 自便
