ansible安装(源码、centos6)

github安装（还有其他安装方法）

• 下载

git clone git://github.com/ansible/ansible.git --recursive

cd ./ansible

• 复制ansible根目录中的examples目录下的ansible.cfg配置文件到/etc/ansible/目录下

cp examples/ansible.cfg /etc/ansible/

• 创建hosts文件

vim /etc/ansible/hosts

• 需要的python模块

sudo pip install paramiko PyYAML Jinja2 httplib2 six

• 启动

source ./hacking/env-setup

• 一旦运行env-setup脚本,就意味着Ansible从源码中运行起来了.默认的inventory文件是 /etc/ansible/hosts.inventory

$ echo "127.0.0.1" > ~/ansible_hosts
$ export ANSIBLE_HOSTS=~/ansible_hosts

SSH认证

• 在~/.ssh目录下生成钥id_rsa.pub(公钥)和id_rsa

ssh-keygen
# 然后一直回车

• 将公钥发到被管节点192.168.1.100的root用户下的.shh目录，生成authorized_keys

ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.1.100

• 验证是否成功

ssh root@192.168.1.100

• 提示Failed to connect to the host via ssh

chown username: /home/username/.ssh
chown username: /home/username/.ssh/*
chmod 700 /home/username/.ssh
chmod 600 /home/username.ssh/*

验证

• 执行命令

ansible 192.168.1.100 -u root -m ping

• 返回结果

192.168.1.100 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
