LINUX如何 部署ansible

        主：192.168.170.49
        被：192.168.170.18

一、启动系统前，加一块光驱，把安装镜像文件放到光驱中

二、配置Yum文件
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# rm -f *
[root@localhost yum.repos.d]# vi cdrom.repo
[BaseOS]
name=BaseOS
baseurl=file:///media/BaseOS
enabled=1
gpgcheck=0

[AppStream]
name=AppStream
baseurl=file:///media/AppStream
enabled=1
gpgcheck=0

[ansible]
name=ansible
baseurl=file:///mnt/ansible
enabled=1
gpgcheck=0

三、挂载光驱，安装ansible
mount /dev/sr1 /media
mount /dev/sr0 /mnt

yum -y install ansible

四、修改配置文件
cd  /etc/ansible/
vim hosts
192.168.1.20

vim ansible.cfg
[defaults]
inventory = /etc/ansible/hosts      
ask_pass = False                          
host_key_checking = False             
remote_user = marry                      
[privilege_escalation]                      
become=True
become_method=sudo
become_user=root
become_ask_pass=False

        被：192.168.170.18

五、配置marry免密
1、在远程上新建用户marry
ansible all -m shell -a "useradd marry" -u root -k

2、修改marry的密码
ansible all -m shell -a "echo 123456 |passwd --stdin marry" -u root -k

3、生成公钥对
ssh-keygen

4、把marry的公钥传给被控192.168.1.20
ssh-copy-id marry@192.168.1.20

5、把marry用户提权到root
ansible all -m shell -a ‘echo marry ”ALL=(ALL) NOPASSWD:ALL”>>/etc/sudoers.d/marry’ -u root -k
    
6、测试一下
ansible node2 -m shell -a "ls /root"
