如何在Denodo5.5中的嵌入式tomcat容器中安装Denodo OData服务？

Question

我想将定制的OData服务安装到Denodo5.5中的嵌入式Tomcat容器中。

我发现Denodo提供的指令有点让人困惑，因此我将发布到堆栈溢出，并包括答案，希望其他人发现它有用。

Answer 1

停工Denodo

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

获得Denodo OData Service.zip

下载Denodo OData Service.zip文件并将其解压缩到/tmp，以便您拥有：

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

“安装”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)

其他考虑因素

由于您现在使用的是嵌入式Tomcat容器，并且odata服务在其中运行，所以每次停止/启动Denodo时，都需要停止/启动OData服务。

阻止德诺多

1. 首先，通过OData停止$DENODO_HOME/bin/odata_service_shutdown.sh服务
2. 然后通过$DENODO_HOME/bin/vqlserver_shutdown.sh阻止德诺多

起动德诺多

1. 首先，通过$DENODO_HOME/bin/vqlserver_startup.sh启动Denodo
2. 然后，通过OData启动$DENODO_HOME/bin/odata_service_startup.sh服务。

管理员用户访问

如果不希望管理员用户通过odata进行访问，则更改$DENODO_HOME/resources/apache-tomcat/conf/context.xml文件中的设置并重新启动。
