Linux环境在线安装python3

安装依赖包

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

　cd /opt

　

下载python3：

　wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz

　

设定安装位置（根据需要进行设置，我安装在/usr/local/python3目录下）

mkdir -p /usr/local/python3

tar -zxvf Python-3.7.9.tgz

 

yum install gcc

 

yum install libffi-devel -y

进入python文件夹，生成编译脚本(指定安装目录)

cd Python-3.7.9

./configure --prefix=/usr/local/python3

 

make

make install

建立Python3,pip3软连接

ln -sf /usr/local/python3/bin/python3 /usr/bin/python3

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

添加环境变量path

vim /etc/profile

(i)

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH

(wq)

source ~/.bash_profile

 

验证python3是否正常

python3

pip3 -V
