在作es backup和es restore(导入)时，需要停es集群中的data节点，只保留master节点。

以下图说明，星号标识的为master节点，其他为data节点。

停两个节点之前，可以在页面上确认红色标示的docs值，再停两个data节点，检查运行着的节点其docs值与停之前一致。

备份脚本es_backup.sh

#!/bin/bash

filename=`date +%Y%m%d%H`

backesFile=es$filename.tar.gz

mkdir -p /xor/elasticsearch/es_snapshot

mkdir -p /xor/elasticsearch/es_backup/es_dump

es_backup_dir=/xor/elasticsearch/es_backup

es_snapshot_dir=/xor/elasticsearch/es_snapshot

chmod -R 777 $es_snapshot_dir

curl -XPUT localhost:9200/_snapshot/es_snapshot -d '{"type":"fs","settings":{"location":"/xor/elasticsearch/es_snapshot"}}'

cd $es_backup_dir/es_dump

curl -XDELETE localhost:9200/_snapshot/es_snapshot/$filename?

echo -e '\nsleep 5\n'

sleep 10

curl -XPUT localhost:9200/_snapshot/es_snapshot/$filename?wait_for_completion=true

echo -e '\nsleep 5\n'

sleep 5

cp $es_snapshot_dir/* $es_backup_dir/es_dump -rf

cd ..

tar czf $backesFile es_dump/

rm es_dump -rf

cd $es_snapshot_dir

rm * -rf

echo -e '\nes data backup succeed!\n'

还原脚本es_restore.sh

#!/bin/bash

filename=$1

backesFile=es$filename.tar.gz

mkdir -p /xor/data2/packages/aqua/backup/es/es_snapshot

mkdir -p /xor/data2/packages/aqua/backup/es/es_backup/es_dump

es_backup_dir=/xor/data2/packages/aqua/backup/es/es_backup

es_snapshot_dir=/xor/data2/packages/aqua/backup/es/es_snapshot

chmod -R 777 $es_snapshot_dir

curl -XPUT localhost:9200/_snapshot/es_snapshot -d '{"type":"fs","settings":{"location":"/xor/data2/packages/aqua/backup/es/es_snapshot"}}'

cd $es_backup_dir

tar zxvf $backesFile

rm $es_snapshot_dir/* -rf

cp $es_backup_dir/es_dump/* $es_snapshot_dir -rf

curl -XPOST localhost:9200/_all/_close

echo -e '\nsleep 5\n'

sleep 5

curl -XPOST localhost:9200/_snapshot/es_snapshot/$filename/_restore?

rm es_dump -rf

echo -e '\n es data restore succeed!'

es_delete_by_query.sh

用于删除es的数据。脚本需要传四个参数,参数依次为表名、时间字段名、开始时间、结束时间,示例如下:

./es_delete_by_query.sh vhsession view_begin_time 2018-01-10 00:00:00

2018-01-10 18:00:00

，时间区间包含上下界，时间字段也可以只传日期

#!/bin/sh

# example: sh ./es_delete_by_query.sh "bundle" "licensing_window_start" "2018-01-05 15:30:00" "2018-01-05 15:30:00"

# example: sh ./es_delete_by_query.sh "bundle" "licensing_window_start" "2018-01-05" "2018-01-06"

doc_type=$1

datefield=$2

start_time=$3

end_time=$4

if [ ! -n "$start_time" ]; then

echo "the start_time is empty,please input again...."

exit 1

else

tt=`date -d "$start_time" +"%FT%T+0800"`

if [ 0 -eq $? ]

then

if [ 0 -eq $? ]

then

echo "args: doc_type = ${doc_type},datefield = ${datefield}, start_time = ${start_time}, end_time = ${end_time}"

}

}

}

}

}

}

}

}'

read -p "please input '1'(otherwise not) to confirm if you need delete:" flag

if [ "1" = "$flag" ]; then

echo "delete response : "

curl -XDELETE http://localhost:9200/aquapaassearch/${doc_type}/_query?pretty -d '
