如何在 Denodo 5.5 的嵌入式 tomcat 容器中安装 Denodo OData 服务？

Question

我想将自定义 OData 服务安装到 Denodo 5.5 中的嵌入式 Tomcat Web 容器中。

我发现 Denodo 提供的说明有些令人困惑，因此我发布到 Whosebug 并包括答案，希望其他人发现它有用。

Answer 1

关闭 Denodo

$DENODO_HOME/bin/vqlserver_shutdown.sh
sleep 15
ps -ef | grep denodo | grep -v grep

获取 Denodo OData Service.zip

下载 Denodo OData Service.zip 文件并将其解压缩到 /tmp，这样您就可以：

/tmp/denodo-odata2-service-5.5-20160129

'Install' OData 服务

# copy the war file to the webapps folder
cp /tmp/denodo-odata2-service-5.5-20160129/denodo-odata2-service-5.5.war $DENODO_HOME/resources/apache-tomcat/webapps/

# Copy the odata xml to the embedded tomcat container
cp /tmp/denodo-odata2-service-5.5-20160129/scripts/denodo-odata2-service-5.5.xml $DENODO_HOME/resources/apache-tomcat/conf/DenodoPlatform-5.5/localhost/

# Copy the startup/shutdown scripts to the bin folder
cp /tmp/denodo-odata2-service-5.5-20160129/scripts/*.sh $DENODO_HOME/bin
chmod u+rwx $DENODO_HOME/bin/odata*.sh

# change the DENODO_HOME directory in the $DENODO_HOME/bin/odata*.sh scripts
vi $DENODO_HOME/bin/odata_service_startup.sh   # look for DENODO_HOME and update it
vi $DENODO_HOME/bin/odata_service_shutdown.sh  # look for DENODO_HOME and update it

进行适当的配置更改

# Add a reference to the Denodo JAR in the catalina.properties file
vi $DENODO_HOME/resources/apache-tomcat/conf/catalina.properties
# Look for shared.loader
# Add this to the end of the shared.loader line:
${catalina.base}/../../lib/vdp-jdbcdriver-core/denodo-vdp-jdbcdriver.jar

# update the server.xml.template file to include a JNDI resource by putting the following in the <GlobalNamingResources> section
vi $DENODO_HOME/resources/apache-tomcat/conf/server.xml.template

<Resource name="jdbc/VDPdatabase"
    auth="Container"
    type="javax.sql.DataSource"
    username="admin" password="***********"
    url="jdbc:vdb://localhost:9999/admin"
    driverClassName="com.denodo.vdp.jdbc.Driver"
    initialSize="5" maxWait="5000"
    maxActive="120" maxIdle="5"
    validationQuery="select * from dual()"
    poolPreparedStatements="true"/>

# Change the permissions on server.xml.template so other people can't read your denodo admin password:
chmod go-rwx $DENODO_HOME/resources/apache-tomcat/conf/server.xml.template
chmod go-rwx $DENODO_HOME/resources/apache-tomcat/conf/server.xml

# update the context.xml to point to the JNDI resource in and also add the properties to the <Context> section (add all of the below to the <Context> section)
vi $DENODO_HOME/resources/apache-tomcat/conf/context.xml

<ResourceLink name="jdbc/VDPdatabase"
    global="jdbc/VDPdatabase"
    type="javax.sql.DataSource"/>

<Environment type="java.lang.String" name="odataserver.address" value="/denodo-odata.svc"/>
<Environment type="java.lang.Integer" name="server.pageSize" value="1000"/>
<Environment type="java.lang.Boolean" name="enable.adminUser" value="true"/>

启动它并确保它正常工作

$DENODO_HOME/bin/vqlserver_startup.sh
# wait for Denodo and Tomcat to start

# deploy/start the odata webapp
$DENODO_HOME/bin/odata_service_startup.sh

# Go to 
http://hostname:9090/denodo-odata2-service-5.5/denodo-odata.svc/databasename
(but change "databasename" to your virtual database name)

其他注意事项

由于您现在使用的是嵌入式 Tomcat 网络容器并且其中包含 odata 服务运行，因此每次 stop/start Denodo 时您还需要 stop/start OData 服务

正在停止 Denodo

首先，通过$DENODO_HOME/bin/odata_service_shutdown.sh
然后通过$DENODO_HOME/bin/vqlserver_shutdown.sh

启动 Denodo

首先，通过 $DENODO_HOME/bin/vqlserver_startup.sh
然后，通过$DENODO_HOME/bin/odata_service_startup.sh

管理员用户权限

如果您不想让管理员用户通过 odata 访问，请更改 $DENODO_HOME/resources/apache-tomcat/conf/context.xml 文件中的设置并重新启动。
