1、Clickhouse連接端口默認8123，但是Clickhouse默認情況下不允許其他設備進行http連接，所以需要更改clickhouse的默認配置:
1 [root@master local]# vim /etc/clickhouse-server/config.xml
新增一行，默認是注釋的，讓本地服務可以遠程連接遠程部署的Clickhouse服務，如下所示：
如果不添加上面的配置，遠程連接，報下面的錯誤，如下所示：
1 Unexpected driver error occurred while connecting to the database 2 ru.yandex.clickhouse.except.ClickHouseException: ClickHouse exception, code: 210, host: 192.168.110.133, port: 8123; Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 3 ru.yandex.clickhouse.except.ClickHouseException: ClickHouse exception, code: 210, host: 192.168.110.133, port: 8123; Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 4 ClickHouse exception, code: 210, host: 192.168.110.133, port: 8123; Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 5 ClickHouse exception, code: 210, host: 192.168.110.133, port: 8123; Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 6 Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 7 Connect to 192.168.110.133:8123 [/192.168.110.133] failed: Connection refused: connect 8 Connection refused: connect 9 Connection refused: connect
2、Dbeaver連接Clickhouse的時候，所需的jar包通過Dbeaver可能下載不下來，此時可以先下載下來，然后手動依賴即可，不過有的需要下載的jar包很多，這個時候可以根據maven工程下載到本地，然后挑出來放到自己的目錄，然后進行手動依賴即可。
1 <project xmlns="http://maven.apache.org/POM/4.0.0" 2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> 4 <modelVersion>4.0.0</modelVersion> 5 <groupId>com.bie</groupId> 6 <artifactId>clickhouse</artifactId> 7 <version>0.0.1-SNAPSHOT</version> 8 9 <dependencies> 10 <dependency> 11 <groupId>ru.yandex.clickhouse</groupId> 12 <artifactId>clickhouse-jdbc</artifactId> 13 <version>0.2.6</version> 14 </dependency> 15 </dependencies> 16 </project>
具體手動依賴，如下所示：
嗯，上面的方法確實有點麻煩，如果想省事，可以使用此鏈接下載即可：
