安装Python3.5
- 准备编译环境
123 | 123yum groupinstall 'Development tools'yum install yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel | 123 | yum groupinstall 'Development tools'yum install yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel |
|---|---|---|---|
123 | yum groupinstall 'Development tools'yum install yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel |
2. 下载安装包
1 | 12wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz | 12 | wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz |
|---|---|---|---|
12 | wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz |
3. 编译
12345 | 12345tar xf Python-3.5.0.tgzcd Python-3.5.0 ./configure --prefix=/usr/local/python3 make make install | 12345 | tar xf Python-3.5.0.tgzcd Python-3.5.0 ./configure --prefix=/usr/local/python3 make make install |
|---|---|---|---|
12345 | tar xf Python-3.5.0.tgzcd Python-3.5.0 ./configure --prefix=/usr/local/python3 make make install |
4. 设置环境变量
1 | 1echo 'export PATH=#PATH:/usr/local/python3/bin' >> ~/.bashrc | 1 | echo 'export PATH=#PATH:/usr/local/python3/bin' >> ~/.bashrc |
|---|---|---|---|
1 | echo 'export PATH=#PATH:/usr/local/python3/bin' >> ~/.bashrc |
5. 替换python2
12 | 12rm /usr/bin/pythonln -sv /usr/local/bin/python3.5 /usr/bin/python | 12 | rm /usr/bin/pythonln -sv /usr/local/bin/python3.5 /usr/bin/python |
|---|---|---|---|
12 | rm /usr/bin/pythonln -sv /usr/local/bin/python3.5 /usr/bin/python |
(这样做的目的是在系统任意目录下敲入python调用的都是python3.5的命令，而非系统默认的2.6.6。但是这样会导致依赖python2.6的yum不能使用因此还要修改yum配置)
6. 更新yum配置
1 | 1ll /usr/bin | grep python | 1 | ll /usr/bin | grep python |
|---|---|---|---|
1 | ll /usr/bin | grep python |
(这里的/usr/bin目录下面包含以下几个文件的（ll | grep python），其中有个python2.6，只需要指定yum配置的python指向这里)
1 | 12 vim /usr/bin/yum | 12 | vim /usr/bin/yum |
|---|---|---|---|
12 | vim /usr/bin/yum |
通过vim修改yum配置，#!/usr/bin/python改为#!/usr/bin/python2.6,保存退出，完成python3的安装
7.运行python
