FreeSWITCH 可能沒有響應端口 8021 上的請求

Question

• 重新啟動 BigBlueButton 服務器時出現以下錯誤：

Starting BigBlueButton
Job for freeswitch.service failed because the control process exited with error code.
See "systemctl status freeswitch.service" and "journalctl -xe" for details.

# Potential problems described below
grep: /opt/freeswitch/var/log/freeswitch/freeswitch.log: No such file or directory

#
# Error: Unable to connect to the FreeSWITCH Event Socket Layer on port 8021
#

• 首先，我認為 freeswitch 的數據庫文件已損壞，因此在 setps 下執行以解決它（如 BBB 文檔中所述）：

$ sudo systemctl stop freeswitch 
$ rm -rf /opt/freeswitch/var/lib/freeswitch/db/* 
$ sudo systemctl start freeswitch

• 但是 FreeSWITCH 並沒有在啟動時創建新的數據庫文件。

• **$/opt/freeswitch/bin#./freeswitch**的 output 如下：
