Linux服务器日志备份到本地

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

[[email protected] 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：

[[email protected] ~]# 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 huagzl1! scp /opt/soft/spring-cloud/member-9076-weixin/logs/2017-05/mealtime-member-9076-all-$(date -d "yesterday" +%Y-%m-%d).tar.gz  [email protected]:/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

[[email protected] ~]# ssh [email protected]

The authenticity of host ‘fwally.eicp.net (175.0.222.186)‘ 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 ‘fwally.eicp.net,175.0.222.186‘ (ECDSA) to the list of known hosts.

[email protected]‘s password:                                         #输入登录用户的密码即可登录至本地服务器上

-bash-4.2$

4、设置crontab定时任务，执行传送日志到本地的脚本

[[email protected] ~]# crontab -l

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