Ansible安装配置及使用
Ansible工具的安装与配置
Ansible基于SSH,不需要在远程端安装任何软件,只需要在管理端安装ansible及其组件即可。
Ansible使用前提是已配置ssh密钥免登陆。
一、安装组件:
yum install python-devel
pip install setuptools
pip install pycrypto
pip install PyYAML
pip install Jinja2
pip install paramiko
pip install simplejson
安装setuptools如果遇到这个错误:
Traceback (most recent call last): File "/usr/bin/pip", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 72, in <module> import packaging.requirements File "/usr/lib/python2.7/site-packages/packaging/requirements.py", line 59, in <module> MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker") TypeError: __call__() takes exactly 2 arguments (1 given)
解决:
vim /usr/lib/python2.7/site-packages/packaging/requirements.py
修改:
#MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker") MARKER_EXPR = originalTextFor(MARKER_EXPR)("marker")
下载ansible源码:http://releases.ansible.com/ansible/
安装:
tar zxvf ansible-2.2.0.0 cd ansible-2.2.0.0 python setup.py install
安装完毕后,设置配置文件:
mkdir /etc/ansible
cp ansible-2.2.0.0/examples/ansible.cfg /etc/ansible/ cp ansible-2.2.0.0/examples/hosts /etc/ansible/
在hosts文件中定义远程操作的主机
ansible默认远程连接端口号为22,用户名为root,可以在hosts文件中自定义:
[servers]
192.168.0.2 ansible_ssh_port=1234 ansible_ssh_user=ahaii
