Linux下安装Python3.6

1.安装Python3.6 依赖环境安装

　　# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel gcc

2.下载Python3.6 

　　官方网站：

　　https://www.python.org/downloads/

# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

3.安装Python3.6

　　我个人习惯安装在/usr/local/python3：

　　 创建目录：

　　　　　　　#mkdir -p/usr/local/python3

　　　　解压你下载好的Python包（我下载的是Python3.6.1.tgz）

 # tar -zxvf Python-3.6.1.tgz

4.进入解压后的目录，编译安装。

# cd Python-3.6.1
# ./configure --prefix=/usr/local/python3

#make &&  make install

5.建立python3的软链

# ln -s /usr/local/python3/bin/python3 /usr/bin/python3

6.并将/usr/local/python3/bin加入PATH环境变量

# vim ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH

保存退出

生成更改的环境变量：

# source ~/.bash_profile

检查Python3及pip3是否正常可用：

 # python3 -V
 Python 3.6.1
 # pip3 -V
 pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
