Question

我有一个关于知识的问题（opensource BI软件 - www.knowage-suite.com）。

有人能告诉我如何使用SQL Server连接创建DataSource吗？

Answer 1

下面给出了安装Knowage和设置数据库的步骤。

安装MySQL 1。 sudo apt-get install mysql-server

2。修改了/etc/mysql/mysql.conf.d/mysqld.cnf并更改了从

    date           category
2018-03-01           abcd
2018-03-02           defc
2018-03-02 00:00:00  acd
2018-03-02 00:00:00  bac
2018-03-03           xyz

3。 mysql -u root -p

            bind-address            = 127.0.0.1 
            to
            bind-address            = *

安装Java

            ALTER USER 'root'@'%' IDENTIFIED BY ''mypswd ';
            GRANT ALL PRIVILEGES ON * . * TO 'root'@'%' IDENTIFIED BY ''mypswd';
            FLUSH PRIVILEGES;
            service mysql restart

安装Knowage 1.下载Knowage

            sudo add-apt-repository ppa:webupd8team/java
            sudo apt-get update
            sudo apt-get install oracle-java8-installer
            sudo apt-get install oracle-java8-set-default 

            export JAVA_HOME=/usr/lib/jvm/java-8-oracle
            export PATH=$JAVA_HOME/bin:$PATH

2。创建交换记忆（https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04）

            wget http://download.forge.ow2.org/knowage/Knowage-6_2_0-RC-CE-Installer-Unix-20180509.zip
            unzip Knowage-6_2_0-RC-CE-Installer-Unix-20180509.zip

设置知识

            sudo swapon --show
            free -h
            df -h
            sudo fallocate -l 4G /swapfile
            ls -lh /swapfile
            sudo chmod 600 /swapfile
            ls -lh /swapfile
            sudo mkswap /swapfile
            sudo swapon /swapfile
            sudo swapon --show
            free -h

在conf / server.xml中添加数据库源

        sh Knowage-6_2_0-RC-CE-Installer-Unix-20180509.sh -c 


        Used existing MySQL DB and it created knowage_ce with following tables.

下载MySQL Connector并复制到lib目录

        <Resource name="jdbc/knowage" auth="Container"
  type="javax.sql.DataSource" 
  driverClassName="com.mysql.jdbc.Driver"
  url="jdbc:mysql://localhost:3306/knowage_ce"
  username="root"
  password="mypswd" 
  maxActive="20" maxIdle="10"
  maxWait="-1"/>

在/ bin

中启动知识服务器

        cp mysql-connector-java-5.1.46.jar /home/babbarkrishan/knowage/Knowage-Server-CE/lib/

希望它能解决你的问题。

Answer 2

0> put MSSQL JDBC driver into `./<your_knowage_installation_directory>/lib` folder

1> log in (on web-UI) as administrator  
2> data source  
3> click on red '+' sign  
4> give a label and choose your dialect (SQL-Server)
5> fill your credential (need SQLSErver auth, not active directory)
6> insert into JDBC this: `jdbc:sqlserver://<YOUR_SERVER_IP>`  
7> insert `com.microsoft.sqlserver.jdbc.SQLServerDriver` as driver

8> create your dataset as a query (remember `use <your_db_name>` at the beginning of your query)
