Python3编译安装
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
cd #回到用户目录
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
tar -xvJf Python-3.7.0.tar.xz
3.编译安装python
mkdir /usr/local/python3 #创建编译安装目录
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
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5.验证是否成功
python3 -V
pip3 -V
#01 python及python3-pip
yum install -y python3-pip rust
#注：rust是语言环境，pip3安装ansible会要求安装
#02 升级pip与配置pip源
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip
pip3 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
