我使用 Virtualbox 在 Ubuntu-Server 14.4 上安装了 Kamailio 4.0，并在另一个 Ubuntu 服务器上安装了 MySQL 服务器。
192.168.0.131：MySQL服务器
192.168.0.141:卡迈利奥 4.0
我把数据库的地址从 localhost 改成了 192.168.0.131。但是连接不上。我在 Google 上搜索了很多，但找不到解决办法。 您需要什么信息来帮助我？
我可以使用以下命令访问服务器：
mysql -h 192.168.0.131 -u kamailio -p
一些输出：
ahmad@ubuntu2:/$ kamctl start
INFO: Starting Kamailio :
ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed
