python3.5安装
1.安装相关依赖库（工具包）
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y
2.到python官网找到下载路径, 用wget下载
wget https://www.python.org/ftp/python/3.5.6/Python-3.5.6.tgz
#python源码的下载地址。（全都在这了）
https://www.python.org/ftp/python/
3.解压tgz包
tar -zxvf Python-3.5.1.tgz
cd Python-3.5.0 做配置
./configure --prefix=/usr/python3 #安装目录在/usr/python3
make && make install
4.建立软连接
-
mv /usr/bin/python /usr/bin/python.bak #删除原有python2的链接
-
$ ln -s /usr/python/bin/python3 /usr/bin/python #建立新的软链接
