[[email protected] soft_bak] ./configure

[[email protected] soft_bak] make

[[email protected] soft_bak] make install

也可以使用yum安裝

搜尋 ： yum search ncurses

安裝 ： yum install ncurses

軟體包

Python-2.7.tar.bz2   psycopg2-2.6.1.tar.gz   psutil-3.2.2.tar.gz

安裝 python2.7

[[email protected] soft_bak]# tar jxvf Python-2.7.tar.bz2

[[email protected] soft_bak]# cd Python-2.7

[[email protected] Python-2.7]# ./configure --prefix=/usr/local/python2.7/

[[email protected] Python-2.7]# make

[[email protected] Python-2.7]# make install

添加/usr/local/python2.7/bin/到Linux的環境變數中

[[email protected] bin]# echo $PATH

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

[[email protected] bin]# PATH="$PATH":/usr/local/python2.7/bin/

[[email protected] bin]# echo $PATH

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/python2.7/bin/

刪除/usr/bin中的python檔案，為python2.7建立串連

[[email protected] bin]# cd /usr/bin/

[[email protected] bin]# rm -rf python

[[email protected] bin]# ln -s /usr/local/python2.7/bin/python ./python

[[email protected] bin]# python
