我已经编写了一个 systemd 单元来在启动时启动我的应用程序:
cat [email protected]
[Unit]
Description=Start my application
After=local-fs.target network.target
[Service]
WorkingDirectory=/apps/scope
ExecStart=/apps/scope/scripts/startAtBoot.sh
Type=forking
PIDFile=/apps/scope/scripts/startAtBoot.pid
User=%i
#Group=
TimeoutSec=30min
[Install]
WantedBy=multi-user.target
cat /apps/scope/scripts/startAtBoot.sh
#!/bin/bash
#### Description: Startup applications at system reboot
#set -x
(. ~/.bash_profile && /apps/scope/scripts/envMaint.sh start >> /apps/scope/ca/profile-root/runtime/logs/envMaint-`date +\%m\%d`.log 2>&1)&
echo $! > /apps/scope/scripts/startAtBoot.pid
当我启动这项服务时:
[root@alvd17p01 ~]# systemctl start [email protected]
我可以看到父进程和子进程运行了一段时间。
[root@alvd17p01 ~]# systemctl status [email protected]

但几分钟后,设备状态变为停用(stop-sigterm)

我不明白为什么它会失败。我的 envMaint.sh 以状态 0 退出。startAtBoot.pid 有子进程的 pid。
有人能帮我解决我做错的地方吗?
