1 創建ssh秘鑰
yum install epel-release -y
yum install sshpass -y
ssh-keygen -t rsa

2 批量復制秘鑰并授權
ansible web -m shell -a ‘mkdir ~/.ssh’ -k
ansible web -m copy -a ‘src=~/.ssh/id_rsa.pub dest=~/.ssh/authorized_keys mode=0600’ -k

3 測試
ssh 10.0.0.20
ssh 10.0.0.21

問題1：
[root@ansible-10 ansible]# ansible web -m ping -k
SSH password:
10.0.0.21 | FAILED! => {
“msg”: “to use the ‘ssh’ connection type with passwords, you must install the sshpass program”
}
10.0.0.20 | FAILED! => {
“msg”: “to use the ‘ssh’ connection type with passwords, you must install the sshpass program”
}

解決方法：
yum install epel-release -y
yum install sshpass -y
