我在 systemd 中加载 vpp.service 时遇到问题。我写了以下服务。
[Unit]
Description=Vector Packet Processing Process
After=syslog.target network.target auditd.service
[Service]
#ExecStartPre=-/bin/rm -f /dev/shm/db /dev/shm/global_vm /dev/shm/vpe-api
#ExecStartPre=-/sbin/modprobe uio_pci_generic
ExecStart=/usr/IMS/current/bin/vpp/vpp -c /usr/IMS/current/bin/vpp/startup_new.conf
Type=forking
Restart=on-failure
RestartSec=5s
[Install]
WantedBy=multi-user.target
我得到以下输出：
vpp.service - Vector Packet Processing Process

一段时间后，我想我会像这样崩溃：

谁能帮我吗 ？
答案1
systemd 没有停止任何事情。 你的守护进程正在退出，并且 systemd 正在清理您所说的辅助剩余进程。
在某种程度上，这是因为您没有按照 VPP doco 规定的方式运行它，即nodaemon在配置文件中有和使用Type=simple。
而且您只给人们提供了部分堆栈跟踪，没有符号，可以使用早些时候（不是“一段时间后”；读取时间戳）您的守护进程彻底崩溃。世界上没有洞察力的人不可能调试它。

因此，严格来说，这个是非问题的答案是“否”。
