NetWorker：在具有“Unable to Contact Authentication Server on Host Networker_server_hostname and Port 9090”的 Linux 服务器上nmc_config失败

• NetWorker Management Console （NMC） 服务器安装在基于 RHEL 的 Linux 操作系统上。
• 运行 NMC 配置脚本 （/opt/lgtonmc/bin/nmc_config） 时，它无法在 authc 端口 9090 上联系身份验证服务器。

[root@networker_server_hostname /]# /opt/lgtonmc/bin/nmc_config
The embedded web server inside the NMC server must run as a non-root user.
Dell recommends that you specify a user that has limited privileges and file access permissions. Default user name used is 'nsrnmc'.
Do you want to create new(cn) certificate or use existing(ue) certificate [cn]?
Create new certificate for https configuration.
Specify the directory to use for the LGTOnmc database[/nsr/nmc/nmcdb]:
Do you want to migrate the NMC server data from a previous LGTOnmc 8.x.x release [n]?
Specify the host name of the Networker Authentication Service host [Networker_server_hostname]:
WARNING: Unable to contact authentication server on host Networker_Server_hostname and port 9090
Do you want to specify a different authentication server host or port [y]?

1. 以下错误来自 /opt/lgtonmc/logs/install.log

129356:gstauthcfg: Unable to get supported versions from authentication server: Received HTTP code 403 from proxy after CONNECT
Server Message : Make sure that server is running

2. 以下命令显示处于活动状态的代理：

[root@Networker_server_hostname /]# env |grep -i proxy
http_proxy=http://:8080
https_proxy=http://:8080

1. 记下系统上配置的代理：

[root@Networker_server_hostname /]# env | grep -i proxy
http_proxy=http://:8080
https_proxy=http://:8080

2. 如果在 /etc/profile 中指定了代理条目，则注释它们并注销。
3. 再次登录 NetWorker 服务器并重新运行 NMC 配置脚本： sudo /opt/lgtonmc/bin/nmc_config
