一、实验背景
CentOS7.x上默认python版本为2.7.5,有时候,我们的一些程序需要高版本3.x版本python。
如果想要使用高版本的python,又不动原来版本的python,需要编译安装一个3.x版本。
二、下载python源码包、编译工具和依赖
# wget https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tar.xz
# yum -y install make gcc zlib-devel openssl-devel bzip2-devel ncurses-devel gdbm-devel readline-devel sqlite-devel libffi-devel libpcap-devel libdbi-devel tk-devel xz-devel sysstat
# xz -d Python-3.8.3.tar.xz
# tar -xvf Python-3.8.3.tar
# cd Python-3.8.3/
# ./configure --prefix=/usr/local/python3
# make
# make install
# /usr/local/python3/bin/python3.8 -V
三、安装python模块
# ll /usr/local/python3/lib/
# /usr/local/python3/bin/pip3 install pymysql
# find /usr/local/python3/ -name "*mysql*"
# ll /usr/local/python3/lib/python3.8/site-packages/
从上面输出可以看出,编译安装的python,安装模块的保存目录为 /usr/local/python3/lib/python3.8/site-packages
如果其他机器需要3.x版本python及所需模块,可以将 /usr/local/python3 打包过去释放。
四、python2.7.5的相关目录
# rpm -qa | grep 2.7.5
# rpm -ql python-2.7.5 | grep bin
# rpm -ql python-libs
五、参考
