centos7安装Python3.7

直接上安装脚本：

#centos7：
yum install libffi-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y
#Ubuntu：
#apt-get install -y zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev iblzma-dev libffi-dev libc6-dev ruby zlib1g-dev
wget https://repo.huaweicloud.com/python/3.7.1/Python-3.7.1.tgz
tar zxf Python-3.7.1.tgz
cd Python-3.7.1
./configure --prefix=/usr/local/python3
make && make install 
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
mkdir /root/.pip 
echo '[global]' >~/.pip/pip.conf
echo 'index-url = https://pypi.douban.com/simple/ '  >>~/.pip/pip.conf
pip3 install --upgrade pip
pip3 install ipython
ln -s /usr/local/python3/bin/ipython3 /usr/bin/ipython3

手动安装教程：

1、下载：

wget “https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz”
或者用华为镜像加速下载：https://repo.huaweicloud.com/python/3.7.1/Python-3.7.1.tgz

2、安装：

依赖包：
yum install libffi-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y
配置：./configure —prefix=/usr/local/python3
编译安装：make && make install

3、添加可执行命令

将python3和pip3 添加软链到执行目录下/usr/bin
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
成功之后直接输入命令：python3或者pip3 都能正常补全

4、升级pip3到最新版本

配置国内pip源
mkdir /root/.pip
echo ‘[global]’ >~/.pip/pip.conf
echo ‘index-url = https://pypi.douban.com/simple/ ’ >>~/.pip/pip.conf
pip3 install —upgrade pip

5、安装ipython3

pip3 install ipython
安装前：

6、安装后：

配置ipython3的软链接
ln -s /usr/local/python3/bin/ipython3 /usr/bin/ipython3
直接输入：ipython3就可以直接补全进去
安装ipython2方法：
yum -y install python-pip
pip install —upgrade pip
pip install ipython
