If you specify a user that does not exist, the configuration process will provide you with

ERROR: Command /opt/lgtonmc/bin/gstdbinit -U postgres -n 5432 /nsr/nmc/nmcdb failed!
在無現有 NMC 資料庫 （/nsr/nmc/nmcdb） 的系統上安裝 NMC 伺服器軟體時，可能會出現此問題。在nmc_config腳本文件期間建立的 postgres 使用者無法初始化 NMC 資料庫，因為作業系統 /tmp 目錄上設定的許可權不正確。此目錄應具有所有使用者的完整讀取、寫入、執行許可權。postgres 使用者會在 /tmp 下建立 .lock 檔案，如果無法執行，nmcdb 將無法初始化。
1.以 root 2、a 身
分
登入 NetWorker 伺服器。確認 /tmp 擁有所有使用者的完整讀取、寫入、執行存取：
ls -la / |grep /tmp
範例：
# ls -la / |grep tmp
drwxrwxrwt. 51 根根 8192 11 月 14 日 09：41 tmp
注： 以上反白顯示的值表示所有使用者的完整讀取、寫入、執行許可權。如果您有任何其他許可權設定，則需要變更。
2、b.如果許可權不正確，請執行以下操作來更正：
chmod 777 /tmp
範例：
[root@nmcserver linux_x86_64]# ls -la / | grep tmp
drwx------. 51 root root 8192 Nov 16 09:18 tmp
[root@nmcserver linux_x86_64]# chmod 777 /tmp
[root@nmcserver linux_x86_64]# ls -la / | grep tmp
drwxrwxrwx. 51 root root 8192 Nov 16 09:18 tmp
3.重新命名現有的 /nsr/nmc/nmcdb：
mv /nsr/nmc/nmcdb /nsr/nmc/nmcdb.bak
4. 重新執行nmc_config：
[root@nmcserver linux_x86_64]# /opt/lgtonmc/bin/nmc_config

5.確認 GST 服務已啟動：
systemctl status gst
6.如果 NMC 服務未執行，請從下列項目開始：
systemctl 啟動 gst
6.監視 /opt/lgtonmc/logs/gstd.raw以啟動：
