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

谁能告诉我如何使用 SQL Server 连接创建 DataSource？

问候， 托马斯

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)

下面给出了安装 Knowage 和设置 DB 的步骤。

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

2.修改/etc/mysql/mysql.conf.d/mysqld.cnf，从

            bind-address            = 127.0.0.1 
            to
            bind-address            = *

3. mysql -u root -p

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

安装 Java

            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

安装Knowage 1. 下载Knowage

            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

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

            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

  1. 设置知识

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


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

  2. 在 conf/server.xml 中添加数据库源

            <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"/>

  3. 下载 MySQL 连接器并复制到 lib 目录

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

  4. 在 /bin 中启动知识服务器

            sh startup.sh

希望它能解决您的问题。

问候，
