Shell命令,sshpass,非交互SSH密码验证,访问
一:安装sshpass
下载地址:http://sourceforge.net/projects/sshpass/
my下载地址:sshpass-1.05.tar.gz
二:下载完为一个例如:sshpass-1.05.tar.gz,压缩包
#解压并安装
$ tar -zxvf sshpass-1.05.tar.gz
$ cd sshpass-1.05
$ ./configure --prefix=/opt/sshpass
#指定安装目录 --prefix=/opt/sshpass(也可不指定)
$ make
$ make install
$ cp /opt/sshpass/bin/sshpass /usr/bin/
#安装完成
三:安装完成测试,#查看帮助:
sshpass -h
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
四:登陆使用:
sshpass非交互SSH有密码验证登陆:
sshpass -p passroot ssh -p22 root@192.168.10.55
或
sshpass -p passroot ssh -o StrictHostKeyChecking=no -tt root@192.168.10.55注:root为登录名,passroot为登陆密码,192.168.10.55为预登陆的ip地址
注:Shell命令sshpass非交互SSH有密码验证
-tt 防止脚本调用ssh后出现Pseudo-terminal will not be allocated because stdin is not a terminal问题
-o StrictHostKeyChecking=no 避免第一次登录出现公钥检查
五:配合shell使用:
详细见:my 博客“Linux下远程备份、上传工程,重启服务器”
#上传xxx脚本到服务端
sshpass -p pwd scp -P22 ./xxx.sh your_user@127.0.0.1:~/
#-o StrictHostKeyChecking=no 避免第一次登录出现公钥检查。
sshpass -p pwd scp -o StrictHostKeyChecking=no -P22 ./xxx.sh your_user@127.0.0.1:~/
#登陆到服务端地址,执行xxx脚本,将执行结果写入本地文件
sshpass -p pwd ssh -p22 user @127.0.0.1 "sh ~/xxx.sh" >pwdss.txt
#使用文件中的密码
sshpass -f pwd.file ssh -p22 user@127.0.0.1 "sh ~/xxx.sh" >>pwdss.txt
#从环境变量(SSHPASS)读取密码
sshpass -e ssh -p22 user@127.0.0.1 "sh ~/xxx.sh" >>pwdss.txt
