测试脚本执行的环境部署(在jenkins服务器中，要求jenkins服务器和目标的灰度环境是连通的)：
一、安装python3.8
$python#看见2.6.6
Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
$which python#查看python位置,一般是位于/usr/bin/python目录下
1. 安装依赖环境
#yum -y groupinstall "Development tools" #yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
2.下载Python3
进官网：https://www.python.org/downloads/source/
# wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
（最好不要安装最新版：wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz）
3.安装python3
创建目录：
# mkdir -p /usr/local/python3
解压下载好的Python-3.x.x.tgz包
# tar -zxvf Python-3.8.0.tgz
进入解压后的目录，编译安装：
# cd Python-3.8.0
# ./configure --prefix=/usr/local/python3
# make && make install
4.建立python3的软链，创建软链接文件到执行文件路径
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
报错：
ln: creating symbolic link `/usr/bin/pip3': File exists，
解决办法：
1）强制覆盖之前的软链：
ln -sf /usr/local/python3/bin/python3 /usr/bin/python3
ln -sf /usr/local/python3/bin/pip3 /usr/bin/pip3
2）或删除软连接：rm /usr/bin/pip3
3）或清除之前编译的可执行文件及配置文件 && 清除所有生成的文件：
make clean && make distclean
5.并将/usr/local/python3/bin加入PATH
vim /etc/profile #使用su切换回要添加环境变量的用户，修改环境变量
在文档最后添加地址：
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
，保存后退出
$ source /etc/profile #生效环境变量
测试是否安装成功：
-
pip3 -V
-
python3 -V
# 安装自动化测试框架
# pip3 install httprunner
pip升级：
WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
pip install --upgrade pip
如有报错，https://pypi.org/simple/pip/下载最新版安装：
WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
# 看是否安装成功
[root@jenkins:~]# httprunner -V
2.2.4
