Shell脚本-控制多主机操作

环境详情

首先要做到各个主机之间无密ssh连接。这样会最大可能方便的控制。

脚本

命名为status

#!/bin/bashparams=$@i=166for((i=166;i<=169;i++));do        echo -------s$i  $params -------        ssh s$i    "$params"done

测试

[root@s166 bin]# status java -version-------s166 java -version -------bash: java: command not found-------s167 java -version -------bash: java: command not found-------s168 java -version -------bash: java: command not found-------s169 java -version -------bash: java: command not found

What?就给我看这个，它找不到这个命令，那我把它放到/usr/local/bin下

[root@s166 bin]# which java/home/fantj/jdk/bin/java[root@s166 bin]# ln -s /home/fantj/jdk/bin/javajava            javadoc         javah           javapackager    javaws          javac           javafxpackager  javap           java-rmi.cgi    [root@s166 bin]# ln -s /home/fantj/jdk/bin/java ./java[root@s166 bin]# lsjava  jps  status  xcall.sh[root@s166 bin]# status java -version-------s166 java -version -------java version "1.8.0_171"Java(TM) SE Runtime Environment (build 1.8.0_171-b11)Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)-------s167 java -version -------bash: java: command not found-------s168 java -version -------bash: java: command not found-------s169 java -version -------bash: java: command not found

好了，jps同理，我们只要要把命令创立软连接到/usr/local/bin下就可，每个主机都需要设置的。

效果
