python3、ipython3、setup-tools、pip等環境搭建詳細總結

第一個python腳本：

[root@backup ~]# cat helloworld.py

print("hello world")

[root@backup ~]# python helloworld.py

hello world

安裝python3及ipython整體環境，非常麻煩，不注意會經常報錯，安裝不成功，折騰了一天才搞定，流程記錄如下：

第一步：安裝python3.5

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

2、下載下傳Python3.5的源碼包并編譯

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=/application/python  --enable-shared

make

make install

ln –s /application/python/bin/python3  /usr/bin/python3

3、在運作Python之前需要配置庫：

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

ldconfig

4、運作示範：

python3 --version

Python 3.5.0

5、删除編譯Python時所需要的庫，當然也可以不删

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

6、設定别名友善使用，也可以不用設定

alias py=python3

第二步：安裝ipython3

1、需要安裝setup-tools

解壓 unzip setuptools-36.5.0.zip

cd setuptools-36.5.0

/application/python/bin/python3 setup.py install

2、安裝pip

tar xf pip-9.0.1.tar.gz

cd pip-9.0.1

此時會在/application/python/bin下生成一個名為pip pip3 pip3.5的幾個檔案夾，說明pip子產品已經打包進入了python環境。

3、安裝python-setuptools和python-setuptools-devel

通過yum install安裝即可

4、安裝ipython

tar xf ipython-6.0.0.tar.gz

cd ipython-6.0.0

5、配置軟連結或加入系統環境變量

ln -s /application/python/bin/python3  /usr/bin/python3

ln -s /application/python/bin/ipython3  /usr/bin/ipython3

ln -s /application/python/bin/ipython  /usr/bin/ipython
