MongoDB数据库数据清理

清理MongoDB集群数据:

1、登录MongoDB集群(mongos):

# mongo -u username -p password --authenticationDatabase admin 127.0.0.1:27017/admin

2、查询2018-01-31之前的数据(mongos):

mongos> db.tcache.find({"ft":{"$lt":new Date("2018-01-31T00:00:00.000Z")}}).count()
# mongo-u username -p password --authenticationDatabase admin 127.0.0.1:27017/yqtrack_gather01 --eval 'db.tcache.find({"ft":{"$lt":new Date("2018-01-31T00:00:00.000Z")}}).count()'

3、删除2018-01-31之前的数据(mongos):

mongos> db.tcache.deleteMany({"ft":{"$lt":new Date("2018-01-31T00:00:00.000Z")}})
# mongo -u username -p password --authenticationDatabase admin 127.0.0.1:27017/yqtrack_gather01 --eval 'db.tcache.deleteMany({"ft":{"$lt":new Date("2018-01-31T00:00:00.000Z")}})'

收缩MongoDB节点数据库:

1、登录Mongod节点(mongod):

# mongo -u __system -p "$(tr -d '\011-\015\040' < /usr/local/mongodb/etc/mongodb.key )" --authenticationDatabase local 172.16.1.151:27018/yqtrack_gather07

2、确认节点为从数据库:

rs1:SECONDARY> rs.status()

3、设置从数据库节点可以读写:

rs1:SECONDARY> db.getMongo().setSlaveOk()

4、切换至对应数据库:

rs1:SECONDARY> use yqtrack_gather01;

5、强制收缩对应数据库:

rs1:SECONDARY> db.runCommand({compact:'tcache',force:true });
# mongo -u __system -p "$(tr -d '\011-\015\040' < /usr/local/mongodb/etc/mongodb.key )" --authenticationDatabase local 172.16.1.87:27018/yqtrack_gather01 --eval 'db.runCommand({compact:"tcache",force:true})'

6、将主节点降级为从节点:

rs1:PRIMARY> rs.stepDown()

---------------------------------------------------------------- shell ---------------------------------------------------------------------

查询指定节点,指定日期区间的数据量:

#!/bin/bash
for((p=1;p<=10;p+=1))
do
for((d=592;d>=506;d-=5))
do
day=`date -d -"$d days" +%Y-%m-%d`
echo "$day"
day_utc=""$day"T00:00:00.000Z"
date="'db.tcache.find({\"ft\":{\"\$lt\":new Date(\"$day_utc\")}}).count()'"
if [ "$p" -lt '10' ]
then
mongo -u username -p password --authenticationDatabase admin 127.0.0.1:27017/yqtrack_gather0"$p" --eval "$date"
RESULT=$?
else
mongo -u username -p password --authenticationDatabase admin 127.0.0.1:27017/yqtrack_gather"$p" --eval "$date"
fi
sleep 5
done
done

收缩指定节点的数据:

#!/bin/bash
for((d=1;d<=10;d+=1))
do
if [ "$d" -lt '10' ]
then
mongo -u __system -p "$(tr -d '\011-\015\040' < /usr/local/mongodb/etc/mongodb.key )" --authenticationDatabase local 127.0.0.1:27018/yqtrack_gather0"$d" --eval 'db.runCommand({compact:"tcache",force:true})'
else
mongo -u __system -p "$(tr -d '\011-\015\040' < /usr/local/mongodb/etc/mongodb.key )" --authenticationDatabase local 127.0.0.1:27018/yqtrack_gather"$d" --eval 'db.runCommand({compact:"tcache",force:true})'
fi
done

[THE END]
