centos6.5 安装python3.5

一、CentOS6.5 安装Python 的依赖包

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

二、下载Python3.5的源码包并编译

wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz
tar xf Python-3.5.0.tgz
cd Python-3.5.0
./configure --prefix=/usr/local --enable-shared
make
make install
ln –s /usr/local/bin/python3 /usr/bin/python3

三、在运行Python以前须要配置库：

echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
ldconfig

四、运行演示：

python3 --version
Python 3.5.0

五、删除编译Python时所须要的库

yum groupremove "Development tools" --remove-leaveas
yum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel --remove-leaves

六、设置别名方便使用

alias py=python3

 

七、CentOS 安装easy_install、pip的方法

CentOS 安装easy_install的方法：

wget -q http://peak.telecommunity.com/dist/ez_setup.py
python ez_setup.py
八、CentOS安装python包管理安装工具pip的方法以下：

wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz

注意：wget获取https的时候要加上：--no-check-certificate

tar zvxf 1.5.5    #解压文件
cd pip-1.5.5/
python3 setup.py install

OK，这样就安装好pip了，

下面来安装 requests吧。

pip3 install requests
