Linux服務器日志備份到本地

1、確定線上服務器的日志文件名稱和路徑

2、一臺本地服務器能連接公網，創建一個日志賬戶，設置密碼

3、線上服務器要求：

 a、確定是否已安裝sshpass包

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

  sshpass-1.06-1.el7.x86_64

  如不存在即安裝yum install -y sshpass

  b、寫腳本傳送

  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@備份主機地址:/logbak/124/                    

  #需確認/logbak/124目錄已存在

  c、確認ssh是否能登錄到遠程服務器

  [root@iZwz95ywngc71vxzcd5yx4Z ~]# ssh logbak@備份主機地址:/logbak/124/ 

  The authenticity of host '備份主機地址 (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                 #確認yes

  Warning: Permanently added '備份主機地址,xxx.xxx.xxx.xxx' (ECDSA) to the list of known hosts.

  logbak@備份主機地址's password:                                         #輸入登錄用戶的密碼即可登錄至本地服務器上

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

  -bash-4.2$

4、設置crontab定時任務，執行傳送日志到本地的腳本

   [root@iZwz9ghdadtaey1msor7gnZ ~]# crontab -l

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