Type Status Report

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

Cause

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。

Resolution

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：
  1. 登录到 NetWorker 服务器并切换到 root：
sudo su -
  1. 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。
  1. 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
and
systemctl start networker.
  1. 确认已创建以下文件夹：
/nsr/authc/webapps/nwrestapi

[root@networker-mc]:~# ls -l /nsr/authc/webapps/nwrestapi/
total 0
drwx------. 2 nsrtomcat nsrtomcat  44 Jul  6 12:22 META-INF
drwx------. 3 nsrtomcat nsrtomcat  21 Jul  6 12:22 v1
drwx------. 3 nsrtomcat nsrtomcat  21 Jul  6 12:22 v2
drwx------. 3 nsrtomcat nsrtomcat  21 Jul  6 12:22 v3
drwx------. 6 nsrtomcat nsrtomcat 107 Jul  6 12:22 WEB-INF
  1. 如果创建了 nwrestapi 目录，请运行 REST API 查询。

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

确认使用什么 Java 实例 NetWorker
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。
  1. 卸载 NetWorker 软件包。这不会删除任何 NetWorker 数据库或配置资源。
  2. 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。
  3. 确认存在以下路径：
C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\webapps\nwrestapi


确认 NetWorker authc 路径存在
