NetWorker：服务器服务无法在 Linux 操作系统上启动。

• NetWorker 服务器安装在基于 Linux 的操作系统上。
• 执行了 Java 升级或 NetWorker Runtime Environment (NRE) 的安装。
• NetWorker 服务器的 nsrd 进程未启动。将出现以下错误。

[root@NSR_HOSTNAME ~]# systemctl start networker
Job for networker.service failed because the control process exited with error code. See "systemctl status networker.service" and "journalctl -xe" for details.

1. 通过 SSH 登录 NetWorker 服务器。
2. 切换到 root 用户：

sudo su -

3. 切换到 NetWorker 的 authc 脚本目录 cd /opt/nsr/authc-server/scripts。
4. 运行 authc 服务配置脚本： 

/opt/nsr/authc-server/scripts/authc_configure.sh

systemctl start networker

完成的脚本示例：

[root@NSR_HOSTNAME ~]# cd /opt/nsr/authc-server/scripts
[root@NSR_HOSTNAME scripts]# /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.

The Apache Tomcat will use "NSR_HOSTNAME" 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.
