centos6.8环境升级至python3.6.3及paramiko安装

python3安装 paramiko安装

yum -y install python
python -V
python 2.6

cd /usr/local/

 

yum -y groupinstall 'Development Tools'
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel
yum install openssl-devel zlib-devel

我安装过程出现报错，安装前需要做以下yum安装
<--
yum groupinstall -y development
yum install -y zlib-dev openssl-devel sqlite-devel bzip2-devel libxslt-devel libffi-devel
yum install gcc libffi-devel python-devel openssl-devel
-->

 

https://www.python.org/downloads/source/
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz #周文俊使用的
./configure --prefix=/opt/Python #安装目录可以自己定义无所谓。
make
make install
ln -s /opt/Python/bin/python3 /usr/bin/python3 或者echo 'export PATH=$PATH:/usr/local/python3/bin' >> ~/.bashrc

pip3安装
1.首先安装setuptools
　　小伙伴们可以通过官方模块库来下载：https://pypi.python.org/pypi
https://pypi.python.org/pypi/setuptools/38.2.3
wget --no-check-certificate https://pypi.python.org/packages/41/80/268fda78a53c2629128f8174d2952c7f902c93ebaa2062b64f27aa101b07/setuptools-
38.2.3.zip#md5=0ae64455d276ff864b40aca9c06ea7c1
unzip setuptools-38.2.3.zip
cd setuptools-38.2.3
python3 setup.py build
python3 setup.py install

2.然后直接安装pip就搞定了。。

https://pypi.python.org/pypi/pip
wget --no-check-certificate https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-
9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9
tar -zxvf pip-9.0.1.tar.gz
cd pip-9.0.1
python3 setup.py build
python3 setup.py install
pip install -U pip

安装完成之后我们再来看下python的bin目录下都有什么东西吧
ls /opt/python/bin

/opt/Python/bin/pip3 install pymysql

安装paramiko

git clone https://github.com/paramiko/paramiko.git
cd paramiko
python3 setup.py install

ps:出现报错（error: Setup script exited with error: command 'gcc' failed with exit status 1）
执行下面的yum安装，再执行一次python3 setup.py install后搞定。
yum groupinstall -y development
yum install -y zlib-dev openssl-devel sqlite-devel bzip2-devel libxslt-devel libffi-devel
yum install gcc libffi-devel python-devel openssl-devel

注：python默认指向了python3，yum不能正常使用，需要编辑yum的配置文件：
vi /usr/bin/yum
将#!/usr/bin/python 改为#!/usr/bin/python2.6保存退出。
yum -y install tree (测试yum恢复正常使用）
