systemd:似乎在启动命令 运行 后立即执行 ExecStop 脚本
systemd: seems like ExecStop script is executed immediately after the start command is run
我正在尝试在 RHEL 7 上启动一个 docker-compose 项目作为 systemd
服务。这是我的 systemd
脚本 (/etc/systemd/system/wp.service
):
[Unit]
Description=wp service with docker compose
Requires=docker.service
After=docker.service
[Service]
EnvironmentFile=/home/ec2-user/projects/wp/project-dir/vars.env
WorkingDirectory=/home/ec2-user/projects/wp/project-dir
# ExecStartPre=/usr/bin/docker-compose down
ExecStart=/usr/bin/docker-compose up -d --build --remove-orphans
# ExecStop=/usr/bin/docker-compose down
[Install]
WantedBy=multi-user.target
当我执行以下命令时:
sudo systemctl status wp.service
一切正常 - 容器 运行 并保持 运行ning。这是 sudo systemctl status wp.service
的输出
