ansible安装

yum install epel-release -y

yum install ansible -y

vim /etc/ansible/hosts
[test]
192.168.1.[230:232] ansible_ssh_port=22222
[test:vars]
ansible_ssh_pass="1"

ansible配置

1> 禁用每次执行ansbile命令检查ssh key host
host_key_checking = False

2> 开启日志记录
log_path = /var/log/ansible.log

3> ansible连接加速配置

[accelerate]
#accelerate_port = 5099
accelerate_port = 10000
#accelerate_timeout = 30
#accelerate_connect_timeout = 5.0

# If set to yes, accelerate_multi_key will allow multiple
# private keys to be uploaded to it, though each user must
# have access to the system via SSH to add a new key. The default
# is "no".
accelerate_multi_key = yes

五、测试
最后测试下在三台管理机器批量执行一个ping命令

 ansible all -m ping
ansible y -m shell -a '''echo "rcAp4quYasQ7" | passwd --stdin root'''
