1、确定线上服务器的日志文件名称和路径

2、一台本地服务器能连接公网，创建一个日志账户，设置密码

3、线上服务器要求：

 a、确定是否已安装sshpass包

  [root@iZwz9ghdadtaey1msor7gnZ sh]# rpm -qa|grep sshpass

  sshpass-1.06-1.el7.x86_64

  如不存在即安装yum install -y sshpass

 

  b、写脚本传送

  Such as：

  [root@iZwz9ghdadtaey1msor7gnZ ~]# cat logbak.sh

  #!/bin/bash

  cd /opt/soft/spring-cloud/member-9076-weixin/logs/2017-05/

  tar zcf mealtime-member-9076-all-$(date -d "yesterday" +%Y-%m-%d).tar.gz mealtime-member-all-$(date -d "yesterday" +%Y-%m-%d)-1.log

  sshpass -p passwd scp /opt/soft/spring-cloud/member-9076-weixin/logs/2017-05/mealtime-member-9076-all-$(date -d "yesterday" +%Y-%m-%d).tar.gz  logbak@备份主机地址:/logbak/124/                    

  #需确认/logbak/124目录已存在

 

  c、确认ssh是否能登录到远程服务器

  [root@iZwz95ywngc71vxzcd5yx4Z ~]# ssh logbak@备份主机地址:/logbak/124/ 

  The authenticity of host '备份主机地址 (xxx.xxx.xxx.xxx)' can't be established.

  ECDSA key fingerprint is d1:9e:2e:3f:50:cf:58:3c:fc:49:6d:13:e2:c4:03:95.

  Are you sure you want to continue connecting (yes/no)? yes                 #确认yes

  Warning: Permanently added '备份主机地址,xxx.xxx.xxx.xxx' (ECDSA) to the list of known hosts.

  logbak@备份主机地址's password:                                         #输入登录用户的密码即可登录至本地服务器上

  Last login: Fri May 12 12:56:08 2017 from 192.168.3.10

  -bash-4.2$

     

4、设置crontab定时任务，执行传送日志到本地的脚本

   [root@iZwz9ghdadtaey1msor7gnZ ~]# crontab -l

   45 8 * * *      /bin/bash  /root/logbak.sh
