使用expect在实现跨机器拿日志

1、shell脚本

config_file_path=$1  #集群的ip
port=$2 #获取集群服务端口中的日志
sjc=$3 #时间戳
user_name="sdbadmin"
#read -sp "sdbadmin's password: "
passwd="1qaz@WSX123"
#获取当前脚本的执行路径
SCRIPT_PATH=$(cd `dirname $0` ; pwd)

if [ ! -n "${config_file_path}" ];then
        echo "主机名或ip的配置文件不能为空，请检查后重新输入!"
        exit 1
fi

if [ ! -n "${port}" ];then
 echo "待匹配的节点名称不能为空，请检查后重新输入!"
        exit 1
fi

if [  -n "${sjc}" ];then
 if [[  ! ${sjc} =~ "-"  ]];then
         echo "时间格式不正确,请输入yyyy-MM-dd格式的日期!"
         exit 1
 fi
 if [[ ${#sjc} -ne 10 ]];then
                echo "时间格式不正确,请输入yyyy-MM-dd格式的日期!"
                exit 1
        fi
fi

sdb_log_path=$(sdblist -l | grep ${port} | awk '{print $10}')
while read line
do
 defaultPath=${SCRIPT_PATH}/${line}/${port}
 if [ ! -d ${defaultPath} ];then
         mkdir -p ${defaultPath}
 fi
 /bin/expect -f getProductionEnvLog.exp ${user_name} ${passwd} ${line} ${sdb_log_path} ${defaultPath} ${sjc}
done < ${config_file_path}

2、expect脚本

#!/bin/expect -f  

#用户名
set user_name [lindex $argv 0]
#密码
set user_passwd [lindex $argv 1]
#ip地址
set host_name [lindex $argv 2]
#目标机器待复制路径
set sdb_log_path [lindex $argv 3]
#当前机器路径
set sdb_save_log [lindex $argv 4]
#匹配指定日期的日志
set log_date [lindex $argv 5]

if {$log_date == ""} {
 spawn scp   ${user_name}@${host_name}:${sdb_log_path}diaglog/sdbdiag.log   ${sdb_save_log}
        expect "password*"
        send "${user_passwd}\r"
} else {
 spawn scp   ${user_name}@${host_name}:${sdb_log_path}diaglog/sdbdiag.log.${log_date}*   ${sdb_save_log}
 expect "password*"
 send "${user_passwd}\r"
}

#spawn scp   ${user_name}@${host_name}:${sdb_log_path}diaglog/sdbdiag.log.${log_date}*   ${sdb_save_log}
#expect "password*"
#send "${user_passwd}\r"
expect eof
#interact
