Ansible 为用户建立SSH连接：在命令行上指定单个主机时无

在命令行上指定单个主机时，如何设置ssh或ansible_用户

当我指定单个主机时，如下所示：

$ansible-playbook -i "ceph1," jdk.yml
TASK [hadoop : create hadoop group] ********************************************
task path: /playbooks/yarn/roles/hadoop/tasks/install.yml:2
<ceph1> ESTABLISH SSH CONNECTION FOR USER: None

当然，运行以下命令是可以的

$ansible-playbook  jdk.yml

---

您可以传递-e参数：

# ansible -m ping web1 -i inventory/a2  -vvv -e "ansible_user=ceph"
<a2-web1> ESTABLISH SSH CONNECTION FOR USER: ceph

#ansible-m ping web1-i inventory/a2-vvv-e“ansible\u user=ceph”
为用户ceph建立SSH连接

# ansible -m ping web1 -i inventory/a2  -vvv -e "ansible_user=ceph"
<a2-web1> ESTABLISH SSH CONNECTION FOR USER: ceph
