20.31 expect脚本同步文件
·自动同步文件
[[email protected] sbin]# chmod a+x 4.expect [[email protected] sbin]# ./4.expect spawn rsync -av [email protected]:/tmp/12.txt /tmp/ [email protected]'s password: receiving incremental file list 12.txt sent 30 bytes received 84 bytes 76.00 bytes/sec total size is 5 speedup is 0.04 [[email protected] sbin]# cat /tmp/12.txt 1212
(脚本结尾需要加 expect eof 或者 interact )
20.32 expect脚本指定host和要同步的文件
·指定host和要同步的文件
(file一定要写绝对路径)
[[email protected] sbin]# chmod a+x 5.expect [[email protected] sbin]# ./5.expect 192.168.65.129 "/tmp/12.txt" spawn rsync -av /tmp/12.txt [email protected]:/tmp/12.txt [email protected]'s password: sending incremental file list sent 31 bytes received 12 bytes 86.00 bytes/sec total size is 5 speedup is 0.12
20.33 构建文件分发系统
·需求背景对于大公司而言,肯定时不时会有网站或者配置文件更新,而且使用的机器肯定也是好多台,少则几台,多则几十甚至上百台。所以,自动同步文件是至关重要的。
·实现思路首先要有一台模板机器,把要分发的文件准备好,然后只要使用expect脚本批量把需要同步的文件分发到目标机器即可。
·核心命令rsync -av --files-from=list.txt / [email protected]:/
·文件分发系统的实现
·rsync.expect 内容
·/tmp/list.txt内容
·ip list 文件:/tmp/ip.txt
192.168.65.129
·rsync.sh内容
[[email protected] sbin]# chmod a+x rsync.expect [[email protected] sbin]# sh -x rsync.sh ++ cat /tmp/ip.txt + for ip in '`cat /tmp/ip.txt`' + echo 192.168.65.129 192.168.65.129 + ./rsync.expect 192.168.65.129 /tmp/list.txt spawn rsync -av --files-from=/tmp/list.txt / [email protected]:/ [email protected]'s password: building file list ... done root/ root/111/222/ root/111/222/test.txt root/shell/ root/shell/01.sh tmp/ tmp/12.txt sent 369 bytes received 81 bytes 900.00 bytes/sec total size is 71 speedup is 0.16
(在129机器上也可以查看到同步过去的文件)
·思路:
执行 rsync.expect 脚本并且要传递两个参数
而其中之一是多个ip中的一个,把 ip 写到一个文本中,for 循环依次去读一个ip,并传递到脚本中去
在 shell 脚本中写此 for 循环,可以执行
把需要同步的文件绝对目录写入到 list.txt 中,这样可以将需要同步的目录依次同步到 ip.txt 中的机器
20.34 批量远程执行命令
·exe.expect 内容
·exe.sh 内容
·执行脚本
