ansible 安装配置

一、安装ansible

  准备两台机器 192.168.56.128 192.168.56.133

  只需在133上安装ansible即可

  安装epel扩展源

[root@server ~]# yum install -y epel-release

  安装ansible

[root@server ~]# yum install -y ansible

二、ansible 配置密钥

  133 上生成密钥对

  使用 ssh-keygen -t rsa 命令生成，这里不去设置密钥密码

[root@server ~]# ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):          //输入保存私钥的路径，不输入直接回车选用括号中的路径

Created directory '/root/.ssh'.

Enter passphrase (empty for no passphrase):                        //设置一个私钥的密码，这里为空了

Enter same passphrase again:

Your identification has been saved in /root/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

d4:5c:9c:36:41:42:b2:a2:fa:4f:54:c0:5c:d0:52:91 root@server

The key's randomart image is:

+--[ RSA 2048]----+

|     oo==+oo+o   |

|      +.E= o=    |

|      ..+ o. .   |

|     . +         |

|    . . S        |

|   . .           |

|  .   .          |

|   . .           |

|    ...          |

+-----------------+

  去对应目录里查看一下

[root@server ~]# ls -la /root/.ssh/

总用量 16

drwx------  2 root root 4096 7月  10 22:24 .

dr-xr-x---. 4 root root 4096 7月  10 22:23 ..

-rw-------  1 root root 1675 7月  10 22:24 id_rsa

-rw-r--r--  1 root root  393 7月  10 22:24 id_rsa.pub

  把公钥中的内容分别拷贝到服务端和客户端中，以客户端为例：

[root@server ~]# cat /root/.ssh/id_rsa.pub

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAoy3POadrIGR4W3FFq+b3Gb+VRdJphHn83Jrags9pdzngusHIduxD+zDavkok/C2tgiQgtEfth9wftsOBCSiglUMVXJ0S2YEUx6PvQtd5DDPS57PKYV7LFr31JD980Y6jIrE7mr0FJ1TdapIrUn2Oj6mfsgYOmOXQFcBLqo4dDwsx983rC/l6svDAswpYxTR0f1ADeZLKFKddn4gRt3j5DRWgEXvpl6nNCa303SlqOVdUp2Yz5izwNd/n1GmLvdnZeGVpNdVB9y6ikxPJfOKAH4JTxRHDHOhWImPhgMJuNjYsggFBe1xVe53S54Dl5eJeAxZG66sigKcVPtytIm8kWQ== root@server

[root@client ~]# vim /root/.ssh/authorized_keys

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAoy3POadrIGR4W3FFq+b3Gb+VRdJphHn83Jrags9pdzngusHIduxD+zDavkok/C2tgiQgtEfth9wftsOBCSiglUMVXJ0S2YEUx6PvQtd5DDPS57PKYV7LFr31JD980Y6jIrE7mr0FJ1TdapIrUn2Oj6mfsgYOmOXQFcBLqo4dDwsx983rC/l6svDAswpYxTR0f1ADeZLKFKddn4gRt3j5DRWgEXvpl6nNCa303SlqOVdUp2Yz5izwNd/n1GmLvdnZeGVpNdVB9y6ikxPJfOKAH4JTxRHDHOhWImPhgMJuNjYsggFBe1xVe53S54Dl5eJeAxZG66sigKcVPtytIm8kWQ== root@server

  验证一下

[root@server ~]# ssh client.test.com

The authenticity of host 'client.test.com (192.168.56.128)' can't be established.

RSA key fingerprint is 0d:d3:7e:b4:f9:e8:c0:56:ae:9e:c7:e1:97:50:87:b5.

Are you sure you want to continue connecting (yes/no)? yes
