centos7 安装python3.7

备注

以下操作都在root用户下执行
如果不是root用户请在命令前加 sudo

1.安装编译相关工具

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.下载安装包解压

# 创建下载的文件路径（自己找位置即可）
mkdir /usr/download   

# 切换到刚新建的文件夹，
cd   /usr/download  

# 下载
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

# 解压
tar -xvJf  Python-3.7.0.tar.xz

3.编译安装

 # 创建编译安装目录
mkdir /usr/local/python3

# 刚刚解压的目录
cd Python-3.7.0
./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

# 修改pip3的指向
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

5、验证

python3 -V
pip3 -V
