Regularly cut MongoDB database logs under Linux and delete log records before the specified number of days

Description

Operating system: CentOS

MongoDB installation directory:/usr/local/mongodb

MongoDB Database storage directory:/home/data/mongodb/mongodb_data

MongoDB Log storage directory:/home/data/mongodb/mongodb_log

Purpose of implementation:

Save to the MongoDB database log on a daily basis and keep only the last 7 days of log records.

Specific operation:

Use commands from the MongoDB database to cut logs

Ps-def | grep Mongod

KILL-SIGUSR1 <mongod Process id>

1. Create MongoDB database log Cut script

vi/home/crontab/cut_mongodb_log.sh #编辑

#!/bin/sh

Datafile=/home/data/mongodb/mongodb_data #Mongodb数据库存放目录

Logfile=/home/data/mongodb/mongodb_log #Mongodb日志存放目录

Days=7 #代表删除7天前的备份, which is to keep only the last 7 days of backup

/BIN/KILL-SIGUSR1 ' cat $datafile/mongod.lock ' #切割日志

Find $logfile/-mtime + $days-delete #删除7天前的备份文件

: wq! #保存退出

2, add task plan, modify/etc/crontab

Vi/etc/crontab #在最后一行添加

0 0 * * */home/crontab/cut_mongodb_log.sh #表示每天凌晨执行备份

: wq! #保存退出

3. Restart the Crond to make the settings effective

/etc/rc.d/init.d/crond Restart #yum install-y Vixie-cron Installation Scheduled tasks may not be preinstalled on some systems

Chkconfig Crond on #设为开机启动

Service Crond start #启动

Log records similar to MONGODB.LOG.2015-02-28T06-33-20 are generated daily in the/home/data/mongodb/mongodb_log directory

And keep only the last 7 days of logging.

At this point, Linux is timed to cut the MongoDB database log and delete the log records before the specified number of days is complete.
