shell指令碼自動登入伺服器並安裝JDK（代碼教程），shelljdk
1.編寫安裝指令碼

編寫安裝指令碼 install.sh

!/bin/bashURL="https://***/jdk-8u161-linux-x64.tar.gz"yum install -y wgetwget $URLtar -zxvf jdk-8u161-linux-x64.tar.gz -C /usr/localcat >> /etc/profile << EOFexport JAVA_HOME=/usr/local/jdk1.8.0_161export JRE_HOME=\${JAVA_HOME}/jreexport PATH=\${JAVA_HOME}/bin:\$PATHexport CLASSPATH=.:\${AVA_HOME}/lib:\${JRE_HOME}/libEOF

2.ssh免密登入並運行安裝指令碼

#!/bin/bashSERVERS="centos01 centos02 centos03 centos04"PASSWORD=centos## auto login to serverauto_ssh_login(){    expect -c "set timeout -1;    spawn ssh-copy-id $1;    expect {        *(yes/no)* {send -- yes\r;exp_continue;}        *password:* {send -- $2\r;exp_continue;}        eof {exit 0;}    }";}ssh_copy_id(){    for SERVER in $SERVERS    do        auto_ssh_login $SERVER $PASSWORD    done}ssh_copy_idfor SERVER in $SERVERSdo     scp install.sh root@$SERVER:/root    ssh root@$SERVER /root/install.shdone
