前几天使用了 Python2 来编译安装 Ansible，发现 Ansible 已经渐渐不再支持 Python2，这篇文章将使用目前最新版本的模块来安装。

Python Version：Python 3.9.1

setuptools Version：setuptools-51.0.0

pycparser Version：pycparser-2.20

cffi Version：cffi-1.14.4

cryptography Version：cryptography-3.3.1

PyYAML Version：PyYAML-5.3.1

MarkupSafe Version：MarkupSafe-1.1.1

Jinja2 Version：Jinja2-2.11.2

ansible Version：ansible 2.9.13

一、升级 Python 版本
二、安装 ansible 所以模块
三、验证

一、升级 Python 版本

1.安装所需依赖

$ sudo yum -y install libffi-devel openssl-devel python-devel zilb-devel unzip

2.升级至 Python3

$ wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz
$ tar xf Python-3.9.1.tgz
$ cd Python-3.9.1.tgz
$ ./configure
$ sudo make && make install
$ python3 --version
Python 3.9.1

二、安装 ansible 所以模块

注意：如果地址失效，可自行搜索下载 https://pypi.org/

1.setuptools

$ wget https://files.pythonhosted.org/packages/12/e1/b9a2926a3c5a3fb055b8f85052f5baa890106a0e21b64a977c10affea751/setuptools-51.0.0.zip
$ unzip setuptools-51.0.0.zip
$ cd setuptools-51.0.0
$ python3 setup.py install

pyhontModuleNotFoundError: No module named '_ctypes' 
#如果遇到此报错是没有 libffi-devel 这个依赖包导致，yum 安装后还需要重新编译安装一遍 Python

2.pycparser -> cffi 所依赖

error: Could not find suitable distribution for Requirement.parse('pycparser')
#需要先安装 pycparser，cffi 所依赖

$ wget https://files.pythonhosted.org/packages/0f/86/e19659527668d70be91d0369aeaa055b4eb396b0f387a4f92293a20035bd/pycparser-2.20.tar.gz
$ tar xf pycparser-2.20.tar.gz
$ cd pycparser-2.20
$ python3 setup.py install

3.cffi -> cryptography 所依赖

ERROR: Could not find a version that satisfies the requirement cffi>=1.12 (from versions: none)
ERROR: No matching distribution found for cffi>=1.12
#需要先安装 cffi，不然会有以下报错

$ wget https://files.pythonhosted.org/packages/66/6a/98e023b3d11537a5521902ac6b50db470c826c682be6a8c661549cb7717a/cffi-1.14.4.tar.gz
$ tar xf cffi-1.14.4.tar.gz
$ cd cffi-1.14.4
$ python3 setup.py install

4.cryptography

error: Could not find suitable distribution for Requirement.parse('cryptography')
#未安装会有此报错

$ wget https://files.pythonhosted.org/packages/b7/82/f7a4ddc1af185936c1e4fa000942ffa8fb2d98cff26b75afa7b3c63391c4/cryptography-3.3.1.tar.gz
$ tar xf cryptography-3.3.1.tar.gz 
$ cd cryptography-3.3.1
$ python3 setup.py install

关系是这样的 pycparser -> cffi -> cryptography

5.PyYAML

$ wget https://files.pythonhosted.org/packages/64/c2/b80047c7ac2478f9501676c988a5411ed5572f35d1beff9cae07d321512c/PyYAML-5.3.1.tar.gz
$ tar xf PyYAML-5.3.1.tar.gz
$ cd PyYAML-5.3.1
$ python3 setup.py install

6.MarkupSafe -> Jinja2 所依赖

$ wget https://files.pythonhosted.org/packages/b9/2e/64db92e53b86efccfaea71321f597fa2e1b2bd3853d8ce658568f7a13094/MarkupSafe-1.1.1.tar.gz
$ tar xf MarkupSafe-1.1.1.tar.gz 
$ cd MarkupSafe-1.1.1
$ python3 setup.py install

7.Jinja2

$ wget https://files.pythonhosted.org/packages/64/a7/45e11eebf2f15bf987c3bc11d37dcc838d9dc81250e67e4c5968f6008b6c/Jinja2-2.11.2.tar.gz
$ tar xf Jinja2-2.11.2.tar.gz
$ cd Jinja2-2.11.2
$ python3 setup.py install

不然会有以下报错：

ansible 2.9.13 requires jinja2, which is not installed.
ansible 2.9.13 requires PyYAML, which is not installed.

8.编译安装 ansible

$ wget https://releases.ansible.com/ansible/ansible-latest.tar.gz
$ tar xf ansible-latest.tar.gz
$ cd ansible-2.9.13
$ python3 setup.py install

三、验证

1.完善配置文件及验证

$ cp -rp examples/* /etc/ansible/
$ ansible --version
ansible 2.9.13
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.9/site-packages/ansible-2.9.13-py3.9.egg/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.9.1 (default, Dec 21 2020, 10:18:09) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

2.不拷贝的话会出现以下情况

$ ansible --version
ansible 2.9.13
  config file = None
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.9/site-packages/ansible-2.9.13-py3.9.egg/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.9.1 (default, Dec 21 2020, 10:18:09) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
