批量操作远程服务器

搭建splunk，需要在N台服务器上安装splunkforward，操作重复。求助运维无果，求助同事给的解决方案是使用TCL脚本。

所做的事情，往N台服务器上上传splunkforward压缩包，解压，修改配置文件，启动。其中远程机器ip、用户名、密码、需要修改的配置文件的内容都放在my.conf文件中，脚本遍历该文件进行操作。

运行本脚本的机器，需要安装tcl，如果联网直接 yum install expect 即可。

start.sh

#!/bin/bash
my_home=/home/wangc/script
splunk_file_name=splunkforwarder-7.0.tar.gz
cat ${my_home}/my.conf |grep -v '#' | grep -v '^$' |while read line
do
    host=$(echo $line |awk '{printf $1}')
    username=$(echo $line |awk '{printf $2}')
    passwd=$(echo $line |awk '{printf $3}')
    passwd_su=$(echo $line |awk '{printf $4}')
    log_path=$(echo $line |awk '{printf $5}')
    log_idx=$(echo $line |awk '{printf $6}')
    log_type=$(echo $line |awk '{printf $7}')
    ${my_home}/connecthost.tcl ${username} ${passwd} ${host} ${passwd_su} ${log_path} ${log_idx} ${log_type} ${splunk_file_name}
done
