下面给centos的中Python添加环境变量，这样可以使用ipython

[root@node01 ~]# vim .bashrc 
alias python='/usr/bin/python3'
[root@node01 ~]# vim /etc/profile
##########
export PATH=$PATH:/usr/local/python3/bin
[root@node01 ~]# source /etc/profile
[root@node01]# ipython
/usr/local/python3/lib/python3.6/site-packages/IPython/core/history.py:226: UserWarning: IPython History requires SQLite, your history will not be saved
  warn("IPython History requires SQLite, your history will not be saved")
