centos7安裝python3 以及tab補全功能
1.安裝python3
1.1下載python原始碼包
網址:https://www.python.org/downloads/release/python-362/
下載地址:https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz
1.1.1安裝python前的庫環境,非常重要
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y
1.2下載,解壓安裝原始碼包
1、./configure 是用來檢測你的安裝平臺的目標特徵的。比如它會檢測你是不是有CC或GCC,並不是需要CC或GCC,它是個shell指令碼。 2、make 是用來編譯的,它從Makefile中讀取指令,然後編譯。 3、make install是用來安裝的,它也從Makefile中讀取指令,安裝到指定的位置。
wget https://www.python.org/ftp/python/3.4.7/Python-3.4.7.tar.xz
xz -d Python-3.4.7.tar.xz
tar -xf Python-3.4.7.tar
#yum install gcc -y
./configure --prefix=/opt/python make && make install
---------------------
用python檢視預設安裝路徑
>>> import sys
>>> sys.path
['', '/usr/local/lib/python36.zip', '/usr/local/lib/python3.6',
'/usr/local/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/site-packages']
--------------------
python3.4預設沒新增path
在/etc/profile最後一行新增
export PATH=$PATH:/opt/python/bin
然後
source /etc/profile
#python快捷path就被改了,yum用的python2,麻煩
1,安裝python前的庫環境,非常重要
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y
2,把壓縮包拽進來xshell裡
3,解壓 tar -xf Python-3.6.2.tgz
4,移動到opt : mv ./Python-3.6.2.tgz
5,cd /opt
6, mkdir python36
7, ./configure --prefix=/opt/python36
8, make && make install
1.2.3 牛逼的python Tab自動補全
下載setuptool 3.4以上已經預設安裝了easy_install-3.4
下載地址: https://pypi.python.org/pypi/setuptools/36.2.7 下載命令: wget https://pypi.python.org/packages/07/a0/11d3d76df54b9701c0f7bf23ea9b00c61c5e14eb7962bb29aed866a5844e/setuptools-36.2.7.zip#md5=b9e6c049617bac0f9e908a41ab4a29ac 解壓: unzip setuptools-36.2.7.zip 編譯: python3 setup.py build python2 setup.py build 無誤後安裝: python3 setup.py install python2 setup.py install沒什麼用
下載readline
#yum install -y readline-devel -y #pip install readline
tab補全
#python startup file
import readline,rlcompleter
#tab completion
readline.parse_and_bind('tab:complete')
----------------------------
python歷史記錄
#history file
import os
history_file = os.path.join(os.environ["HOME"],".pythonhistory")
[[email protected]_local ~]# echo "export PYTHONSTARTUP='/root/.pythonstartup'" >> /root/.bashrc [[email protected]_local ~]# source /root/.bashrc [[email protected]_local ~]# cat /root/.pythonstartup import os import readline import rlcompleter import atexit #tab completion readline.parse_and_bind("tab: complete") #history file history_file = os.path.join(os.environ["HOME"],".pythonhistory") try: readline.read_history_file(history_file) except IOError: pass atexit.register(readline.write_history_file,history_file) del os,history_file,readline,rlcompleter [[email protected]_local ~]# python Python 2.7.3 (default, Jun 5 2013, 22:40:26) [GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path<tab> #按tab鍵就可以自動補全了 [[email protected]_local ~]# python >>> >>> sys.path #按上下方向鍵即可找到歷史命令整體程式碼
加入python的啟動環境變數,永久生效自動補全
只需要啟動時執行一條命令即可 import rlcompleter, readline readline.parse_and_bind('tab:complete') 可以將上述的程式碼存於~/.pythonrc.py檔案中。 然後,在~/.bashrc中設定 export PYTHONSTARTUP=~/.pythonrc.py 這樣,每次啟動終端,bash就會設定PYTHONSTARTUP這個環境變數,然後,python啟動時就會使用這個變數指定的檔案中的初始化程式碼。 在python直譯器中,輸入一個變數的一部分,或者變數後面加句點,再按TAB鍵就可以看到自動補全的威力。
