# 1.安装依赖包                                                                        #

1）首先安装gcc编译器，gcc有些系统版本已经默认安装，通过  gcc --version  查看，没安装的先安装gcc，yum -y install gcc

2）安装其它依赖包，（注：不要缺少，否则有可能安装python出错，python3.7.0以下的版本可不装 libffi-devel ）

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 libffi-devel

# 2.下载python3.7.4源码，根据需求下载                                  #

1）在https://www.python.org/ftp/python/中选择自己需要的python源码包，我下载的是python3.7.0

(大家也可以去https://www.python.org官网首页下载，找到downloads，就可以选择想要的版本下载了)

1）下载

wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz

2）解压Python-3.7.4.tgz

tar -zxvf Python-3.7.4.tgz

# 3.建立一个空文件夹，用于存放python3程序　　　　　　　　 #

mkdir /python3

# 4.执行配置文件，编译，编译安装　　　　　　　　　　　　 #

cd python3
    ./configure --prefix=/python3/python3.7.4 --with-ssl
    make && make install

【问题解决】:no acceptable C compiler found in $PATH when installing python

执行安装：apt-get install build-essential

【问题解决】：zipimport.ZipImportError: can't decompress data; zlib not available

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \\  
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \\  
xz-utils tk-dev

安装完成没有提示错误便安装成功了

# 5.建立软连接　　　　　　　　　　　　　　　　　　　　　 #

ln -s /python3/python3.7.4/bin/python3 /usr/bin/python3
    ln -s /python3/python3.7.4/bin/pip3 /usr/bin/pip3

# 6.测试一下python3是否可以用　　　　　　　　　　　　　　 #

python3 -V
    pip3 -V

将pip升级到最新版本：

python3 -m pip install --upgrade pip

【问题解决】pip安装时出现"return Command 'lsb\_release -a' returned non-zero exit status 1"

删除lsb\_release文件可解决此问题

sudo rm /usr/bin/lsb_release

# 8.Wagtail安装 #

mkdir wagtail
    
    cd wagtail
    
    python3 -m venv env
    
    source env/bin/activate
    
    pip3 install wagtail
    
    wagtail start mysite
    
    cd mysite
    
    pip3 install -r requirements.txt
    
    python3 manage.py migrate
    
    python3 manage.py createsuperuser

# 9.编写脚本让Blog服务后台运行 #

#!/bin/bash
    cd /root/wagtail/mysite
    nohup python3 manage.py runserver 127.0.0.1:8000  &
