步骤1：编写Java应用程序的启动脚本
首先，创建一个shell脚本来启动你的Java应用程序。例如，假设你的Java应用程序的JAR文件名为myapp.jar，你可以创建一个名为start_myapp.sh的脚本：
#!/bin/bash
# 设置Java应用程序的JAR文件路径
JAR_PATH="/opt/java-server/aokang-footwear-marketing.jar"
# 启动Java应用程序
nohup java -jar "$JAR_PATH" --spring.profiles.active=prod > /opt/java-server/aokang-footwear-marketing.log 2>&1 &
# 获取并输出应用程序的进程ID
echo $! > /var/run/aokang-footwear-marketing.pid
确保脚本具有可执行权限：
chmod +x /path/to/start_myapp.sh
步骤2：创建systemd服务单元文件
接下来，你需要创建一个systemd服务单元文件来管理你的Java应用程序。例如，你可以创建一个名为myapp.service的文件：
[Unit]
Description=aokang-footwear-marketing
After=network.target
[Service]
Type=simple
User=root
WorkingDirectory=/opt/java-server
ExecStart=/opt/java-server/start_aokang-footwear-marketing.sh
SuccessExitStatus=143
Restart=on-failure
RestartSec=10
PIDFile=/var/run/aokang-footwear-marketing.pid
[Install]
WantedBy=multi-user.target
将上述内容保存为/etc/systemd/system/myapp.service。
步骤3：重新加载systemd配置并启动服务
现在，重新加载systemd配置并启动服务：
sudo systemctl daemon-reload sudo systemctl start myapp
要使服务在系统启动时自动启动，可以启用它：
sudo systemctl enable myapp
步骤4：验证服务状态
你可以检查服务的状态以确保它正在运行：
sudo systemctl status myapp
你应该看到类似以下的输出，表明服务正在运行：
root@iZuf61rqdpzwrcbgagt066Z:/etc/systemd/system# sudo systemctl status aokang-footwear-marketing.service
