Ansible does not match the ssh password-free link, and directly use the ssh user password to connect, you must install sshpass first.
sshpass download address: http://sourceforge.net/projects/sshpass/
Run the following commands to install:
tar -zxvf sshpass-1.05.tar.gz
cd sshpass-1.05
./configure
make && make install
After the installation is complete, enter sshpass and the following prompt appears, the installation is successful:
# sshpass
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
-f filename Take password to use from file
-d number Use number as file descriptor for getting password
-p password Provide password as argument (security unwise)
-e Password is passed as env-var "SSHPASS"
With no parameters - password will be taken from stdin
-h Show help (this screen)
-V Print version information
At most one of -f, -d, -p or -e should be used
Add user password to /etc/ansible/hosts file to authenticate ssh connection

"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."

}
When ssh connects for the first time, it will generally prompt to enter yes to confirm that the key string is added to the ~/.ssh/known_hosts file. And there is a fingerprint key string in the ~/.ssh/known_hosts file of this machine
Workaround: Change the following parameters in the ansible.cfg file:
#host_key_checking = False just remove the #
