| 导读 | 经常我们使用脚本登入服务器的时候，如果使用 ssh 命令，经常会提示密码输入，我们不得不手动输入密码，因为 ssh 没有 密码的选项。为了能绕过交互式验证，我们使用 sshpass 命令解决这个问题： |
1. 安装
| ➜ Desktop sudo yum install sshpass | |
| [sudo] password for xuyaowen: | |
| Last metadata expiration check: 0:04:22 ago on Mon 02 Jul 2018 11:25:32 AM CST. | |
| Package sshpass-1.06-5.fc28.x86_64 is already installed, skipping. | |
| Dependencies resolved. | |
| Nothing to do. | |
| Complete! |
检查是否安装
| [] | |
| sshpass-1.06-5.fc28.x86_64 |
2. 查看 sshpass 命令帮助, 也可以使用 man sshpass
View Code
| [root@yaowenxu Desktop]# 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 | |
| -P prompt Which string should sshpass search for to detect a password prompt | |
| -v Be verbose about what you're doing | |
| -h Show help (this screen) | |
| -V Print version information | |
| At most one of -f, -d, -p or -e should be used |
3. 使用密码验证登录
➜ ~ sshpass -p 123 ssh root@10.66.65.15
4. ssh 第一次登录提示问题使用：
ssh -o StrictHostKeyChecking=no
来解决
| ➜ Desktop sshpass -p 123 ssh -o StrictHostKeyChecking=no root@10.66.8.142 | |
| Warning: Permanently added '10.66.8.142' (ECDSA) to the list of known hosts. | |
| Last login: Mon Jul 2 10:51:29 2018 |
5. 优缺点
