systemd错误“无法启动服务:单元服务未正确加载:exec格式错误" [英] systemd error "failed to start service: unit service is not loaded properly: exec format error"

问题描述

我可以从 shell 执行确切的 ExecStart 命令并且它可以工作，但是由于某种原因在这个服务文件中这不起作用 - 有什么想法吗?

I can execute the exact ExecStart command from the shell and it works, but for some reason in this service file this doesnt work-- any ideas?

错误:

Failed to start previewapi.service: Unit previewapi.service is not loaded properly: Exec format error.
See system logs and 'systemctl status previewapi.service' for details.

systemd .service 文件:

systemd .service file:

[Unit]
Description = preview-api
After       = network.target

[Service]
WorkingDirectory=/srv/previewapi
ExecStart   = /usr/bin/java -jar /srv/previewapi/gn-preview-api-0.1.0-SNAPSHOT-standalone.jar

ExecStop    = kill -INT $MAINPID
ExecReload  = kill -TERM $MAINPID

# In case if it gets stopped, restart it immediately
Restart     = always

Type        = simple


[Install]
# multi-user.target corresponds to run level 3
# roughtly meaning wanted by system start
WantedBy    = multi-user.target

sudo journalctl -u previewapi 说:

推荐答案

问题不在于 ExecStart，而在于 ExecStop 和 ExecReload部分——它们也需要是绝对的.

The problem wasn't the ExecStart, it was the ExecStop and ExecReload sections-- they need to be absolute as well.

最终版本:

[Unit]
Description = preview-api
After       = network.target

[Service]
WorkingDirectory=/srv/previewapi
ExecStart=/usr/bin/java -jar /srv/previewapi/gn-preview-api-0.1.0-SNAPSHOT-standalone.jar
ExecStop=/bin/kill -INT $MAINPID
ExecReload=/bin/kill -TERM $MAINPID

# In case if it gets stopped, restart it immediately
Restart     = always

Type        = simple


[Install]
# multi-user.target corresponds to run level 3
# roughtly meaning wanted by system start
WantedBy    = multi-user.target
