1. 首先安装presto

安装教程可以参考官网及下面这篇文章
官方文档
presto安装及连接mysql

完毕可以连接mysql测试一下是否安装成功

2. 下载presto-clickhouse

这里已有大佬实现presto-clickhouse的Connectors,我们直接下载来用就好
https://github.com/zeeshanabid94/presto/tree/presto-clickhouse/presto-clickhouse

3. 编译presto-clickhouse

我们只需要编译presto-clickhouse部分,这里有两种方式
直接在下载的项目里编译,不过有很多check,对maven、jdk版本进行检测,这些按照官网要求来,当然也可以在主pom中关掉check
也可以直接新建一个项目编译
这里我选择新建项目

①:新建项目,拷贝代码

这里我们选择新建一个项目,把下载的presto_clickhouse中的代码拷贝进去

拷贝代码

②:添加clickhouse Connector

在resource下新建META-INF/services 目录,在此目录下新建com.facebook.presto.spi.Plugin文件,在文件中添加com.facebook.presto.plugin.clickhouse.ClickhousePlugin,如下图
这一步主要是为了ConnectorFactory能识别clcikhouse的Connector

配置ClickhousePlugin

③:修改pom文件

④:打包上传

将上述修改好的项目打成jar
在presto安装目录的plugin目录下新建clickhouse目录
mkdir /opt/soft/presto-server-0.223/plugin/clickhouse
将打好的jar上传至该目录
然后在catalog下新建clickhouse.properties

vim /opt/soft/presto-server-0.223/etc/catalog/clickhouse.properties


#写入clickhouse的连接信息
connector.name=clickhouse
connection-url=jdbc:clickhouse://ip:8123
connection-user=
connection-password=

然后前台启动presto

bin/launcher run 

如果出现server started证明clickhouse Connector注册成功

下面用客户端测试
java -jar presto-cli-0.224-executable.jar --server localhost:9000 --catalog clickhouse --schema test
执行show tables;
