對於大公司而言,確定時不時會有網站或者配置文件更新,並且使用的機器確定也是好多臺,少則幾臺,多則幾十甚至上百臺。因此,自動同步文件是相當重要的。shell
首先要有一臺模板機器,把要分發的文件準備好,而後只要使用expect腳本批量把須要同步的文件分發到目標機器便可。vim
rsync -av --files-from=list.txt / root@host:/安全

備註:若是不能保證對方機器有相同的路徑就加上R,編輯rsync.expect
bash
注意:作分發系統expect腳本的前提是須要保證機器密碼同樣,這樣會有一個問題就是若是密碼泄露的話就會有安全隱患,因此能夠作密鑰認證增長安全。ssh
