CentOS7安装python3

1、安装编译Python3的相关依赖

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel

2、安装python3
#下载源码 wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz #解压并进入目录 tar -zxvf Python-3.7.0.tgz cd Python-3.7.0 #生成MakeFile -prefix指定路径 ./configure prefix=/usr/local/python3 #编译 make make install

3、添加软链接
#添加python3的软链接 ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3 #添加 pip3 的软链接 ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

#测试安装是否成功 [root@centos-linux Python-3.7.0]# python3 -V Python 3.7.0

【CentOS7安装python3】注意CentOS自带python2,所以软链接的时候如果想要链接成python而不是python3需要把原本的如软链接删除
