Linux新建systemd文件用systemctl命令来管理

1. 创建systemd服务文件，vi /etc/systemd/system/serviceName.service

[Unit]
Description=custom service
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/script.sh

[Install]
WantedBy=multi-user.target

2. 新建一个可执行脚本/usr/bin/script.sh，无特殊要求，保证有执行权限即可

#!/bin/bash
echo "Hello World!"

3. 增加执行权限

chmod +x /usr/bin/script.sh

4. 启动服务

systemctl start serviceName
# 或
systemctl start serviceName.service

5. 启用服务并使其开机自启

systemctl enable serviceName
# 或
systemctl enable serviceName.service

6. 备注

# 若systemctl未识别新服务，可尝试重载systemd管理器配置
systemctl daemon-reload
