centos下安装python3.7.6

1、安装编译相关软件

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
yum install libffi-devel -y

2、现在安装包解压

cd #回到用户目录
wget https://www.python.org/ftp/python/3.7.6/Python-3.7.6.tar.xz
tar -xvJf  Python-3.7.6.tar.xz

3、编译安装python

mkdir /usr/local/python3 #创建编译安装目录
cd Python-3.7.6
./configure --prefix=/usr/local/python3
make && make install

4、创建软连接

ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

5、验证是否成功

python3 -V
pip3 -V
