## Linux下Python安装
|
||
|
||
>**系统环境**：centos 7.6
|
||
>
|
||
>**Python 版本**：Python-3.6.8
|
||
|
||
### 1. 环境依赖
|
||
|
||
Python3.x 的安装需要依赖这四个组件：gcc， zlib，zlib-devel，openssl-devel；所以需要预先安装，命令如下：
|
||
|
||
```shell
|
||
yum install gcc -y
|
||
yum install zlib -y
|
||
yum install zlib-devel -y
|
||
yum install openssl-devel -y
|
||
```
|
||
|
||
### 2. 下载编译
|
||
|
||
Python 源码包下载地址： https://www.python.org/downloads/
|
||
|
||
```shell
|
||
# wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz
|
||
```
|
||
|
||
### 3. 解压编译
|
||
|
||
```shell
|
||
# tar -zxvf Python-3.6.8.tgz
|
||
```
|
||
|
||
进入根目录进行编译，可以指定编译安装的路径，这里我们指定为 `/usr/app/python3.6` ：
|
||
|
||
```shell
|
||
# cd Python-3.6.8
|
||
# ./configure --prefix=/usr/app/python3.6
|
||
# make && make install
|
||
```
|
||
|
||
### 4. 环境变量配置
|
||
|
||
```shell
|
||
vim /etc/profile
|
||
```
|
||
|
||
```shell
|
||
export PYTHON_HOME=/usr/app/python3.6
|
||
export PATH=${PYTHON_HOME}/bin:$PATH
|
||
```
|
||
|
||
使得配置的环境变量立即生效：
|
||
|
||
```shell
|
||
source /etc/profile
|
||
```
|
||
|
||
### 5. 验证安装是否成功
|
||
|
||
输入 `python3` 命令，如果能进入 python 交互环境，则代表安装成功：
|
||
|
||
```shell
|
||
[root@hadoop001 app]# python3
|
||
Python 3.6.8 (default, Mar 29 2019, 10:17:41)
|
||
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
|
||
Type "help", "copyright", "credits" or "license" for more information.
|
||
>>> 1+1
|
||
2
|
||
>>> exit()
|
||
[root@hadoop001 app]#
|
||
```
