Question

我正在编写linux服务，以将我的springboot Web应用程序部署为服务。这是服务文件springboot.service

[Unit]
Description=My Webapp Java REST Service

[Service]
User=ubuntu
# The configuration file application.properties should be here:

#change this to your workspace
WorkingDirectory=/home/ubuntu

#path to executable. 
#executable is a bash script which calls jar file
ExecStart=/home/ubuntu/spring-start

SuccessExitStatus=143
TimeoutStopSec=10
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

我的脚本文件spring-start.sh

sudo java -jar "/home/ubuntu/FirstWebAppWithoutDB.jar"

我还通过chmod u+x spring-start.sh

授予了spring-start.sh的执行许可。

sudo systemctl daemon-reload

sudo systemctl enable springboot.service

sudo systemctl start springboot

sudo systemctl status springboot

不幸的是，该服务失败并出现错误Exec格式错误：

springboot.service: Failed to execute command: Exec format error
Jul 14 07:39:56 ip-172-31-40-71 systemd[10075]: springboot.service: Failed at step EXEC spawning /home/ubuntu/spring-start.sh: Exec format error

Answer 1

将shebang添加到脚本中

FIREBASE_TEST_UID

和执行权限

#!/bin/bash
sudo java -jar "/home/ubuntu/FirstWebAppWithoutDB.jar"

Answer 2

您的 spring-start.sh 由 bash 执行，您需要在 springboot.service 文件中明确您的 ExecStart，如下所示： ExecStart=/bin/bash /home/ubuntu/spring-start.sh

编写Linux服务时为什么会出现Exec格式错误？
