Message The requested resource [/nwrestapi/v3/global/clients] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.52 NetWorker 服务器安装缺少 nwrestapi 目录。

Linux: /nsr/authc/webapps/nwrestapi/
Windows: C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\webapps\nwrestapi

restapi.log 不存在或未更新：

Linux: /nsr/logs/restapi/restapi.log
Windows: C:\Program Files\EMC NetWorker\nsr\logs\restapi\restapi.log

nwrestapi 路径不存在。REST API 查询无法找到任何端点或关联它应如何显示来自其他 NetWorker 数据库的数据。

nwrestapi 与使用 Java Runtime Environment 的 NetWorker authc 服务一起配置。建议在配置 authc 时使用 NetWorker Runtime Environment （NRE） 以避免潜在的 Java 相关问题。可从 戴尔支持 NetWorker 驱动程序和下载 页面下载最新的 NRE 软件包。
Linux：

登录到 NetWorker 服务器并切换到 root：

sudo su -

确认是否安装了 NRE 以及哪些 Java 实例 NetWorker 配置为使用：

rpm -qa | grep nre
cat /nsr/authc/conf/installrc
[root@networker-mc]:~# rpm -qa | grep nre
nre-8.0.15-1.x86_64
[root@networker-mc]:~#
[root@networker-mc]:~# cat /nsr/authc/conf/installrc
JAVA_HOME=/opt/nre/java/latest
   提醒：可能已安装多个 Java 实例。例如，NRE 和 Oracle JRE 都可以安装在服务器上。上述步骤确认 NetWorker 正在使用什么 Java 安装。
   
运行以下脚本以重新配置 NetWorker authc 服务器。
  
/opt/nsr/authc-server/scripts/authc_configure.sh
[root@networker-mc]:~# /opt/nsr/authc-server/scripts/authc_configure.sh 
Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]: 
The installation process will install an Apache Tomcat instance. For optimum security, EMC NetWorker Authentication Service will use a non-root user (nsrtomcat) to start the Apache Tomcat instance. 
If your system has special user security requirements, ensure that proper operational permissions are granted to this non-root user (nsrtomcat). 
Please refer to NetWorker Installation Guide. 
WARNING: Port 9090 is already in use. 
Do you wish to specify a different port number [y]? n 
The Apache Tomcat will use "networker-mc.emclab.local" as the host name. 
The Apache Tomcat will use "9090" as the port number. 
The NetWorker Authentication Service requires a keystore file to configure encryption and to provide SSL support. 
EMC recommends that you specify a keystore password that has a minimum of six characters. 
Do you want to use the existing keystore /nsr/authc/conf/authc.keystore [y]? 
Specify password for the existing keystore: 
The install will use the existing certificate "emcauthctomcat" for Apache Tomcat.
The install will use the existing certificate "emcauthcsaml" for Authentication Service. 
Creating the installation log in /opt/nsr/authc-server/logs/install.log. 
Performing initialization. Please wait... 
The installation completed successfully.
   
    提醒：需要重新启动 NetWorker 服务才能重新加载 authc。这可以通过以下 systemctl 命令完成：
   
systemctl stop networker
systemctl start networker.
 
   
确认已创建以下文件夹：
  
/nsr/authc/webapps/nwrestapi
[root@networker-mc]:~# ls -l /nsr/authc/webapps/nwrestapi/

如果创建了 nwrestapi 目录，请运行 REST API 查询。
  
Windows： 
   
确认是否安装了 NRE 以及哪些 Java 实例 NetWorker 配置为使用：
  

图 1：确认正在使用的 Java 实例 NetWorker。
 
   
提醒：可能已安装多个 Java 实例。例如，NRE 和 Oracle JRE 都可以安装在服务器上。以上步骤确认 NetWorker 正在使用的 Java 安装。
   
卸载 NetWorker 软件包。这不会删除任何 NetWorker 数据库或配置资源。
   
通过现有安装路径重新安装 NetWorker。重新安装 NetWorker 将重新配置 NetWorker 的身份验证服务。
   
确认存在以下路径：
  
C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\webapps\nwrestapi
