Im新的Devops和即将学习Ansible作为AWS EC2 Ubuntu 16.04 LTS的初学者。Ubuntu中的Ansible配置失败16.04LTS
最初我都推出2个SSH端口22安全组开放的EC2实例，我命名实例作为主和从。
我打成了主人全部启动并运行时的实例。 我将列出步骤逐一跟进
1.我创建了一个叫做用户ansible并发出口令
[email protected]:~$ sudo su
[email protected]:/home/ubuntu# adduser ansible
Adding user `ansible' ...
Adding new group `ansible' (1001) ...
Adding new user `ansible' (1001) with group `ansible' ...
Creating home directory `/home/ansible' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for ansible
Enter the new value, or press ENTER for the default
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n]
2.取消注释的PermitRootLogin yes和PasswordAuthentication yes把在的/ etc/ssh/sshd_config并重新启动ssh
3.更改Visudo文件添加根访问ansible用户
[email protected]:/home/ubuntu# visudo
编辑
# User privilege specification
root ALL=(ALL:ALL) ALL
ansible ALL=(ALL:ALL) ALL
保存并关闭
4.Generated SSH密钥生成
[email protected]:~$ ssh-keygen -t rsa -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ansible/.ssh/id_rsa):
Created directory '/home/ansible/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/ansible/.ssh/id_rsa.
Your public key has been saved in /home/ansible/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:wah0yD9Ngf7hzLIihkEFvNYjPNrzcLubNxGnqFKYrik [email protected]
The key's randomart image is:
+---[RSA 4096]----+
|... .. |
| . o ..o . |
|. + +.o + |
| B + +ooo. |
|++o o.oOS. |
|= = o +.= |
|.+ * . + |
|Eo+ +.+ |
|=o .+= . |
+----[SHA256]-----+
个5.安装Ansible包
$ sudo apt-get install software-properties-common
$ sudo apt-add-repository ppa:ansible/ansible
$ sudo apt-get update
$ sudo apt-get install ansible
真棒！..所有已启动并ansible是安装在主服务器 我发出一个命令来测试ansible
[email protected]:~$ ansible --version
ansible 2.3.0.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]
6.编辑/etc/ansible/hosts并添加了我的从属服务器私有IP（我的ec2在同一个可用区域内的同一子网中），所以我使用私有IP
[我]
172.31.29.197 .save和从属服务器关闭
7.ssh'ed并重复1，2，3个步骤和注销
8。shh'ed到主服务器
[email protected] $ shh [email protected]<Master Ip>
9.Copying公钥发送至从服务器从主服务器
[email protected]:~$ ssh-copy-id 172.31.29.197
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/ansible/.ssh/id_rsa.pub"
The authenticity of host '172.31.29.197 (172.31.29.197)' can't be established.
ECDSA key fingerprint is SHA256:qOW0ZktetcpTNmxRsubxn1kcr8egyNmcA5Uk9+oWc7A.
Are you sure you want to continue connecting (yes/no)? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]'s password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh '172.31.29.197'"
and check to make sure that only the key(s) you wanted were added
[email protected]:~$ ssh 172.31.29.197

[email protected]:~$ logout
Connection to 172.31.29.197 closed.
而且成功配置母校到奴隶无密码ssh连接
直到那时我还没有遇到任何问题。 当我发出的命令Ansible -m ping all 收到错误
172.31.29.197 | FAILED! => {
"changed": false,
"failed": true,
"module_stderr": "Shared connection to 172.31.29.197 closed.\r\n",
"module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n",
"msg": "MODULE FAILURE",
"rc": 0
}
后，当我gooogled我得到一些块我跟着列出步骤由该溶液中。 解决方案是我重复第5步从上面的列表奴隶服务器。从主服务器发出ansible -m ping当我成功消息
我的问题是如何在从安装代理程序的anible，主要特点ansible无代理！
帮助我，如果我错过了任何一个步骤
