ansible不配ssh鏈接，用戶密碼登陸

ansible 不配ssh免密連接，直接用ssh用戶密碼鏈接，要先裝sshpass。

sshpass下載地址：http://sourceforge.net/projects/sshpass/

運行下列命令安裝:

tar -zxvf sshpass-1.05.tar.gz
cd sshpass-1.05                
./configure             
make && make install

安裝完成後輸入sshpass出現以下提示即安裝成功：

# 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

/etc/ansible/hosts文件中添加用戶密碼,認證ssh鏈接

[test]
127.0.0.1 ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass=123456
192.168.1.103 ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass=123456

錯誤彙總：

[root@localhost ~]# ansible test -m ping
127.0.0.1 | FAILED! => {
    "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."
}
192.168.1.103 | FAILED! => {
    "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."
}

ssh第一次鏈接的時候通常會提示輸入yes 進行確認爲將key字符串加入到 ~/.ssh/known_hosts 文件中。而本機的~/.ssh/known_hosts文件中並有fingerprint key串

解決方法：在ansible.cfg文件中更改下面的參數：

#host_key_checking = False 將#號去掉便可
