mysql軟體安裝

至少需要安裝一個mysql客戶端，即要有mysql這個命令；也可以直接安裝一個mysql資料庫，不用可以不啟動；

clickhouse服務端配置mysql埠

vim /etc/clickhouse-server/config.xml

<mysql_port>9004</mysql_port>

修改伺服器端配置，需要重啟clickhouse, 預設日誌輸出 /var/log/clickhouse-server/clickhouse-server.log

下面這種方式，需要在本地配置mysql，然後本地連線，預設省去的連線主機為localhost

[root@ch2 ~]# mysql --protocol tcp -u default
 
 -P 9004
