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 伺服器安裝缺少 nwrestapi 目錄。

Linux: /nsr/authc/webapps/nwrestapi/

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

Linux: /nsr/logs/restapi/restapi.log

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

1. 登入 NetWorker 伺服器，然後切換至 root：

sudo su -

2. 確認是否已安裝 NRE，以及 NetWorker 設定要使用的 JAVA 例項：

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

3. 執行下列腳本，重新設定 NetWorker authc 伺服器。

/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.

systemctl stop networker
and
systemctl start networker.

4. 確認已建立下列資料夾：

/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

5. 如果已建立 nwrestapi 目錄，請執行 REST API 查詢。

1. 確認是否已安裝 NRE，以及 NetWorker 設定要使用的 JAVA 例項：

圖 1：確認 NetWorker 使用的 JAVA 例項。

2. 卸載 NetWorker 套件。這不會移除任何 NetWorker 資料庫或組態資源。
3. 在現有的安裝路徑上重新安裝 NetWorker。重新安裝 NetWorker 會重新設定 NetWorker 的驗證服務。
4. 確認以下路徑是否存在：

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

圖 2：確認 NetWorker authc 路徑存在。

5. 如果已建立 nwrestapi 目錄，請執行 REST API 查詢。
