ansible安装配合Virtualenv

ansible安装

• 让项目运行在一个独立的局部的 Python 环境中，使采用不同环境的项目互不干扰。

安装方式：

yum安装：

安装EPEL源

yum install epel-release
yum install ansible

编译安装：

yum-y install python-jinja2 PyYAML python-paramiko python-babel python-crypto
tar xf ansible-1.5.4.tar.gz
cd ansible-1.5.4
python setup.py build
python setup.py install
mkdir/etc/ansible
cp-r examples/*/etc/ansiblel

Git方式：(我是用的这种)

使用python自带的python virtualenv工具隔离Python3.6、Ansible和系统其他python环境。

编译安装python3.6.5

[root@localhost ~]# wget http://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz

[root@localhost ~]# tar xf Python-3.6.5.tar.xz

[root@localhost ~]# cd Python-3.6.5

安装编译所需的依赖

[root@localhost Python-3.6.5]# yum install -y gcc zlib* openssl*

开始编译

[root@localhost Python-3.6.5]# ./configure --prefix=/usr/local/ --with-ensurepip=install --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"

--prefix=/usr/local/ 
---指定安装路径
--with-ensurepip=install 
----安装pip
--enable-shared   
---disable/enable building shared python library 启用共享函数构建的库
LDFLAGS="-Wl,-rpath /usr/local/lib"
----Wl 将后面跟的参数传递给连接器 ld；-rpath 添加运行时库的搜索路径
现代linux的发行版配置的python都是编译成share library方式，有些第三方软件如mod_wsgi和Blender必须要这样才能正常运行。但是，如果把python编译成share library，就必须告知如何才能找到这个library。有两种办法达到这个目的：
通过在configure命令的最后加入LDFLAGS="-Wl,-rpath /usr/local/lib"选项把路径编译到可执行文件里面去

接下来安装

[root@localhost Python-3.6.5]# make && make altinstall，输入echo $?查看命令是否执行成功

安装virtualenv

[root@localhost Python-3.6.5]# cd /usr/local/bin/

[root@localhost bin]# ln -s /usr/local/bin/pip3.6  /usr/local/bin/pip

[root@localhost bin]# pip install virtualenv  ，速度有点慢安装过程中，如果出现如下 error 信息是，可以尝试切换源重新下载

切换清华源
pip install virtualenv -i https://pypi.tuna.tsinghua.edu.cn/simple/   

安装成功后，创建ansible账户

[root@localhost ~]# useradd deploy

切换到deploy用户

[root@localhost ~]# su - adeploy

安装python3.6virtualenv实例

[deploy@localhost ~]$ virtualenv -p /usr/local/bin/python3.6 .py3-a2.10-env

Already using interpreter /usr/local/bin/python3.6
Using base prefix ‘/usr/local‘
New python executable in /home/deploy/.py3-a2.5-env/bin/python3.6
Also creating executable in /home/deploy/.py3-a2.5-env/bin/python
Installing setuptools, pip, wheel...
done.

Git源码安装ansible最新版

使用root账户安装nss curl

[root@localhost ~]# yum install nss curl -y

然后切到deploy用户，进入之前创建的.py3-a2.5-env目录下，克隆ansible源码

[root@localhost ~]# su - deploy

[deploy@localhost ~]$ cd /home/deploy/.py3-a2.5-env/

[deploy@jenkins .py3-a2.5-env]$ git clone https://github.com/ansible/ansible.git

克隆慢解决方法

去这个网站注册账号https://gitee.com/，点击导入，等几分钟就下载好了

 

然后复制地址下载即可[deploy@jenkins .py3-a2.5-env]$ git clone https://gitee.com/wengsh/ansible.git

 

下载完成后，加载python3.6 virtualenv环境

[deploy@jenkins .py3-a2.5-env]$ source /home/deploy/.py3-a2.5-env/bin/activate

(.py3-a2.5-env) [deploy@jenkins .py3-a2.5-env]$ 

 接下来安装ansible依赖包

(.py3-a2.5-env) [deploy@jenkins .py3-a2.5-env]$ pip install paramiko PyYAML jinja2

在python3.6虚拟环境下加载ansible2.5

(.py3-a2.5-env) [deploy@jenkins ansible]$  source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q 

查看ansible版本

(.py3-a2.5-env) [deploy@jenkins ansible]$ ansible --version

ansible 2.10.0.dev0

  config file = None

  configured module search path = [‘/home/deploy/.ansible/plugins/modules‘, ‘/usr/share/ansible/plugins/modules‘]

  ansible python module location = /home/deploy/.py3-a2.5-env/ansible/lib/ansible

  executable location = /home/deploy/.py3-a2.5-env/ansible/bin/ansible

  python version = 3.6.5 (default, Jan 31 2020, 17:16:22) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

到此，ansible安装完成
