一、安装单机版DBLE

1、下载并安装

通过此链接( https://github.com/actiontech/dble/releases )下载最新版本的安装包

解压并安装dble到指定⽂件夹中：

mkdir -p $working_dir
cd $working_dir
tar -xvf actiontech-dble-$version.tar.gz
cd $working_dir/dble/conf
mv cluster_template.cnf cluster.cnf
mv bootstrap_template.cnf bootstrap.cnf
mv db_template.xml db.xml
mv user_template.xml user.xml
mv sharding_template.xml sharding.xml

2、修改db.xml配置文件

$ cat db.xml
<?xml version="1.0"?>
<!--~ Copyright (C) 2016-2020 ActionTech.~ License: http://www.gnu.org/licenses/gpl.html GPL version 2 or higher.--><dble:db xmlns:dble="http://dble.cloud/" version="4.0"><dbGroup name="dbGroup1" rwSplitMode="2" delayThreshold="100"><heartbeat>show slave status</heartbeat><dbInstance name="instanceM1" url="x.x.x.x:3306" user="root" password="Abcd@1234" maxCon="1000" minCon="10"primary="true" readWeight="1" id="xx1"><property name="testOnCreate">true</property></dbInstance><!--<dbInstance name="instanceS1" url="ip3:3306" user="your_user" password="your_psw" maxCon="1000" minCon="10"  readWeight="2" disabled="true">--><!--<property name="testOnCreate">false</property>--><!--</dbInstance>--></dbGroup><dbGroup name="dbGroup2" rwSplitMode="0" delayThreshold="100" disableHA="true"><heartbeat errorRetryCount="1" timeout="10">show slave status</heartbeat><dbInstance name="instanceM2" url="x.x.x.x:3306" user="u_dtl" password="3bw#N6a9Ap" maxCon="1000" minCon="10"primary="true"><property name="testOnCreate">true</property></dbInstance><!-- can have multi read instances --><!--<dbInstance name="instanceS2" url="ip4:3306" user="your_user" password="your_psw" maxCon="1000" minCon="10" usingDecrypt="true">--><!--<property name="testOnCreate">true</property>--><!--</dbInstance>--></dbGroup>
</dble:db>

3、启动dble

cd /opt/dble/bin

4、测试dble分库，使用man1账户

-P 端口号需要大写# mysql -uman1 -P9066 -hx.x.x.x -p654321

5、测试分表，使用root账户

# mysql -uroot -P8066 -hx.x.x.x -p123456

结果：

二、安装集群版本DBLE

1、拷贝安装包到其他机器

# 1、拷贝压缩包
$ scp dble-3.21.06.5-20220824033617-linux.tar.gz xiaxinyu@xxxxxxrabbitmq39:/opt/dble-3.21.06.5-20220824033617-linux.tar.gz$ scp dble-3.21.06.5-20220824033617-linux.tar.gz xiaxinyu@xxxxxxredis38:/opt/dble-3.21.06.5-20220824033617-linux.tar.gz$ tar -xvf dble-3.21.06.5-20220824033617-linux.tar.gz# 2、初始化配置文件
cd $working_dir/dble/conf
mv cluster_template.cnf cluster.cnf
mv bootstrap_template.cnf bootstrap.cnf
mv db_template.xml db.xml
mv user_template.xml user.xml
mv sharding_template.xml sharding.xml# 3、拷贝相同的配置文件到其他实例
scp db.xml xiaxinyu@xxxxxxredis38:/opt/dble/conf/db.xml
scp db.xml xiaxinyu@xxxxxxrabbitmq39:/opt/dble/conf/db.xmlscp cluster.cnf xiaxinyu@xxxxxxredis38:/opt/dble/conf/cluster.cnf
scp cluster.cnf xiaxinyu@xxxxxxrabbitmq39:/opt/dble/conf/cluster.cnf

2、cluster.cnf配置文件内容

#
# Copyright (C) 2016-2020 ActionTech.
# License: http://www.gnu.org/licenses/gpl.html GPL version 2 or higher.
#clusterEnable=true
# cluster ucore/zk
clusterMode=zk
# zk:  clusterIP=10.186.19.aa:2281,10.186.60.bb:2281
clusterIP=x.x.x.x:2181,x.x.x.x:2181,x.x.x.x:2181
# zk not need cluster.port
# clusterPort=5700
rootPath=/dble
#cluster namespace, please use the same one in one cluster
clusterId=cluster-1
# if HA need sync by cluster, only useful when useOuterHa=true
# needSyncHa=false
# unit is millisecond
# showBinlogStatusTimeout=60000
sequenceHandlerType=2
# valid for sequenceHandlerType=2 or 3
#sequenceStartTime=2010-11-04 09:42:54
# valid for sequenceHandlerType=3 and clusterMode is zk, default true
#sequenceInstanceByZk=true

3、修改bootstrap.cnf文件中instance

# 修改3个实例的配置文件#  base config
-DhomePath=.
-DinstanceName=1
-DinstanceId=1
-DserverId=xxx1#  base config
-DhomePath=.
-DinstanceName=2
-DinstanceId=2
-DserverId=xxx2#  base config
-DhomePath=.
-DinstanceName=3
-DinstanceId=3
-DserverId=xxx3

不修改会引起如下错误：

java.io.IOException: Online path with other IP or serverPort exist,make sure different instance has different instanceName

STATUS | wrapper  | 2022/10/11 10:37:45 | <-- Wrapper Stopped
STATUS | wrapper  | 2022/10/11 10:45:37 | --> Wrapper Started as Daemon

4、zookeeper查看dble节点信息

[zk: localhost:2181(CONNECTED) 3] get /dble/cluster-1/online/
1   2   3
[zk: localhost:2181(CONNECTED) 3] get /dble/cluster-1/online/1
{"instanceName":"1","apiVersion":1,"createdAt":1665455763646,"data":{"serverPort":8066,"hostAddr":"x.x.x.x","startTime":1665455763644}}
[zk: localhost:2181(CONNECTED) 4] get /dble/cluster-1/online/2
{"instanceName":"2","apiVersion":1,"createdAt":1665456341783,"data":{"serverPort":8066,"hostAddr":"x.x.x.x","startTime":1665456341781}}
[zk: localhost:2181(CONNECTED) 5] get /dble/cluster-1/online/3
