Linux Centos7安装python3.7和安装pykmip

原因：安装OpenKMIP/PyKMIP需要python3环境，故需要安装Python3.7

Linux Centos7安装python3.7 1、检查一下原来python的版本和是否有gcc

[root@loaclhost ~]# python -V Python 2.7.5 [root@loaclhost ~]# gcc -version -bash: gcc: 未找到命令 [root@loaclhost ~]# yum -y install gcc

2、python3.7以上版本，安装依赖包:libffi-devel

yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y

3、wget下载python3.7.10

#安装wget

$yum install wget -y

#wget下载python3.7.10

$wget www.python/ftp/python/3.7.10/Python-3.7.10.tgz

也可以手动下载，下载地址

www.python/downloads/

4、解压下载好的Python安装包

$tar -zxvf Python-3.7.10.tgz

5、进入解压后的目录，编译安装

#进入目录

$cd Python-3.7.10

#创建一个空文件夹，存放python3程序

$mkdir /usr/local/python3

#编译安装

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

$make && make install

./configure --prefix=/usr/local/python3执行完成时提示：那么再执行./configure --enable-optimization

If you want a release build with all stable optimizations active (PGO, etc), please run ./configure --enable-optimizations

6、建立Python3的软连接 ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3 7、检查Python3和pip3

[root@loaclhost Python-3.7.10]# python3 Python 3.7.10 (default, Mar 16 2022, 11:54:28)  [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux Type "help", "copyright", "credits" or "license" for more information. >>>

[root@loaclhost Python-3.7.10]# pip3 --version pip 22.0.4 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

或者也可以配置环境变量

vi .bash_profile   ~/.bash_profile PATH=$PATH:$HOME/bin:/usr/bin/python3/bin

或/etc/profile PATH=$PATH:$HOME/bin:/usr/bin/python3/bin

也可以参考：zhuanlan.zhihu/p/142097087

二、安装pykmip

github/OpenKMIP/PyKMIP

$pip3 install pykmip
