初识 Python

１．源码安装 ipython 1.2.1

[root@Client-1]# tar -xf iPython 1.2.1.tar.gz

[root@Client-1]cd ipython 1.2.1

[root@Client-1 ipython-1.2.1]# python setup.py install

２．通过ｐｉｐ安装 ipython 1.2.1

确认是否有epel源

[root@Client-1 ~]# ll /etc/yum.repos.d/

total 36

-rw-r--r--. 1 root root 2572 May 15  2015 Centos-Base.repo

-rw-r--r--. 1 root root 1991 Oct 23  2014 CentOS-Base.repo.backup

-rw-r--r--  1 root root  647 Mar 28  2017 CentOS-Debuginfo.repo

-rw-r--r--  1 root root  289 Mar 28  2017 CentOS-fasttrack.repo

-rw-r--r--  1 root root  630 Mar 28  2017 CentOS-Media.repo

-rw-r--r--  1 root root 7989 Mar 28  2017 CentOS-Vault.repo

-rw-r--r--. 1 root root 1083 May 15  2015 epel.repo(***********要有这个源************)

没有就安装

[root@Client-1 ~]#yum install epel-release-6-8.noarch.rpm

[root@Client-1 ~]#yum install python-pip -y

如果有下面的提示：

You are using pip version 7.1.0, however version 9.0.1 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

Requirement already satisfied (use --upgrade to upgrade): python in /usr/lib64/python2.6/lib-dynload

则：

[root@Client-1 ~]# pip install --upgrade pip

[root@Client-1 ~]#pip install ipython==1.2.1 (指定安装1.2.1 默认安装最新版的)

[root@Client-1 ~]#pip list|grep ipython

ipython (1.2.1)

３．使用ipython

[root@Client-1 ~]# ipython
