linux在python上的编译安装

python 在linux下 的编译安装

1、安装

[root@auh1st ~]# cd /usr/local/src/

[root@auh1st src]# ll

总计 0

[root@auh1st src]# wget

[root@auh1st src]# tar -jxf Python-2.6.tar.bz2

[root@auh1st src]# ll

总计 10724

drwxrwxr-x 17 1000 1000     4096 2008-10-03 Python-2.6

-rw-r–r–  1 root root 10957859 2008-10-03 Python-2.6.tar.bz2

[root@auh1st Python-2.6]# ./configure –prefix=/usr/local/python-2.6

make && make install

2、检测和设置环境变量

[root@auh1st bin]# echo $PATH

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

[root@auh1st bin]# PATH="$PATH":/usr/local/python-2.6/bin

[root@auh1st bin]# echo $PATH

/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/python-2.6/bin

3、删除系统已有的，将新版本覆盖

cd /usr/bin

rm -rf python

ln -s /usr/local/python-2.6/bin/python ./python

[root@auh1st ~]# python

Python 2.6 (r26:66714, Sep 25 2013, 10:14:04)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2

至此python新版 安装成功
