Linux软件自动化部署脚本

首先是免密登录：

#!/bin/bashSERVERS="node-3.itcast.cn node-4.itcast.cn"PASSWORD=123456BASE_SERVER=172.16.203.100auto_ssh_copy_id() {    expect -c "set timeout -1;        spawn ssh-copy-id $1;        expect {            *(yes/no)* {send -- yes\r;exp_continue;}            *assword:* {send -- $2\r;exp_continue;}            eof        {exit 0;}        }";}ssh_copy_id_to_all() {    for SERVER in $SERVERS    do        auto_ssh_copy_id $SERVER $PASSWORD    done}ssh_copy_id_to_allfor SERVER in $SERVERSdo    scp install.sh root@$SERVER:/root    ssh root@$SERVER /root/install.shdone

其次是，执行服务端要在各个客户端上进行安装的脚本：

#!/bin/bashBASE_SERVER=172.16.203.100yum install -y wgetwget $BASE_SERVER/soft/jdk-7u45-linux-x64.tar.gztar -zxvf jdk-7u45-linux-x64.tar.gz -C /usr/localcat >> /etc/profile << EOFexport JAVA_HOME=/usr/local/jdk1.7.0_45export PATH=\$PATH:\$JAVA_HOME/binEOF
