CentOS7.5下安装Python3.7 --python3

1、将本地安装包上传到远程主机上

scp Python-3.7.0.tgz [email protected]:/root

2、登录到远程主机，解压安装包

tar zxvf Python-3.7.0.tgz

3、转到Python-3.7.0目录下

cd Python-3.7.0/

4、安装gcc，因编译需要用到编译器

yum -y install gcc

5、安装到/usr/local目录下

./configure --prefix=/usr/local

6、执行编译

make

7、执行安装

make altinstall

8、删除原有Python2.7的链接，CentOS自带Python2.7.x，使用Python指令后，运行Python2.7。而我们要执行Python指令后运行已安装的Python3.7

rm -v /usr/bin/python

9、创建软链接

ln -s /usr/local/bin/python3.7 /usr/bin/python

ln -s /usr/local/bin/python3.7 /usr/bin/python3

这样执行Python和Python3就可以运行已经安装的Python3.7
