升级到 Ubuntu Bionic 分段错误后 Trafficserver 崩溃（地址未映射到对象 [(nil)]）

我将 Apache Trafficserver 从 Ubuntu Artful 升级到 Bionic，之后我无法启动 Trafficserver，但是我收到了这种错误消息：

[Apr  2 10:47:23.389] traffic_crashlog {0x2b5cd50b9880} ERROR: wrote crash log to /var/log/trafficserver/crash-2018-04-02-104721.log

Google 没有帮助，但我设法通过手动启动 TrafficServer 来调试它：

root@bob:/var/log/trafficserver# traffic_manager 
[E. Mgmt] log ==> [TrafficManager] using root directory '/usr'
[Jun 21 08:15:28.889] Manager {0x7f4b7c9ab740} ERROR: unable to access() local state directory '/var/run/trafficserver': 2, No such file or directory
[Jun 21 08:15:28.889] Manager {0x7f4b7c9ab740} ERROR: unable to access() local state directory '/var/run/trafficserver': 2, No such file or directory
[Jun 21 08:15:28.889] Manager {0x7f4b7c9ab740} ERROR: please set 'proxy.config.local_state_dir'
[Jun 21 08:15:28.889] Manager {0x7f4b7c9ab740} ERROR: please set 'proxy.config.local_state_dir'

此后，我创建了缺失的目录并使其正常工作

mkdir /var/run/trafficserver
chown -R trafficserver:trafficserver /var/run/trafficserver
