如何重新加载systemd服务？

编程问答 2022-08-15

问题描述

我定义了以下服务

[Unit]
Description=Docker Compose Application Service [monitor]
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/eugenekim/Documents/monitor/node-master
ExecStart=/usr/local/bin/docker-compose -f docker-compose.log.yml up -d es-log-00
ExecStop=/usr/local/bin/docker-compose -f docker-compose.log.yml down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

docker-compose.log.yml文件已更改，甚至* .service文件也已更改，但系统坚持以某种方式运行旧定义。

我尝试运行daemon-reload，但没有任何效果。
当我尝试跑步

sudo systemctl reload docker-log                                                                                                                                                              14469ms
Failed to reload docker-log.service: Job type reload is not applicable for unit docker-log.service.
See system logs and 'systemctl status docker-log.service' for details.

它也没有任何作用。

解决方法

我认为您缺少ExecReload。

[Unit]
Description=Docker Compose Application Service [monitor]
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/eugenekim/Documents/monitor/node-master
ExecStart=/usr/local/bin/docker-compose -f docker-compose.log.yml up -d es-log-00
# docker compose will watch for changes
ExecReload=/usr/local/bin/docker-compose -f docker-compose.log.yml up -d es-log-00
# or you want a force restart
#ExecReload=/usr/local/bin/docker-compose -f docker-compose.log.yml restart es-log-00
ExecStop=/usr/local/bin/docker-compose -f docker-compose.log.yml down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target
