# 如果配有SSH信任证书，则无需加K， 使用sudo，则加 -u ansible -sudo
ansible web主机名(单/组) -m ping -k
ansible web1 -m ping -k

第一次配置
首先，需要关闭 对方的防火墙
systemctl stop firewalld.service
其次，ssh一次，yes，成功连接
然后再次执行，就会成功啦
+++++++++++++++++++++++++++++++++
配置SSH无密码访问
为了避免每次都输入密码
ssh-keygen -t rsa
疯狂回车
cd /root/.ssh
id_rsa私钥 id_rsa.pub公钥(下发到被控制主机.ssh目录，命名为authorized_keys)
+++++++++++++++++++++++++++++++++++
或者执行
ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
# 再次ping 无需密码
ansible web主机名(单/组) -m ping
+++++++++++++++++++++++++++++++++++
Briefly recognize
the use of the ansible
Remote command module
# 远程执行命令
ansible web -m command -a "ifconfig"
# 远程执行本机的脚本、其实是scp+shell,远程不会留下脚本
ansible web -m script -a "/root/aaa.sh"
# 远程执行 远端服务器脚本
ansible web -m script -a "/root/aaa.sh"
