linux脚本将JAR安装进systemctl

注意事项:

1. 修改JAR_NAME和SERVICE_NAME变量的值
2. 注意修改启动ExecStart启动命令
3. 默认java在/usr/bin/目录下有快捷方式
4. 将当前脚本和jar文件放在同一目录下

脚本

#!/bin/bash

SCRIPT_DIR="$( cd "$( dirname "${
      BASH_SOURCE[0]}" )" && pwd )"
JAR_HOME="$SCRIPT_DIR"
JAR_NAME="your jar name"
SERVICE_NAME="your server name"
INSTALL_DIR="/etc/systemd/system"

# Create a systemd service file
echo "[Unit]
Description=$SERVICE_NAME
After=network.target

[Service]
WorkingDirectory=$JAR_HOME
ExecStart=/usr/bin/java -jar -Xms200m -Xmx2000m $JAR_NAME
ExecReload=/bin/kill -HUP $MAINPID
ExecStop=/bin/kill -15 $MAINPID
Restart=always
User=root
Group=root

[Install]
WantedBy=multi-user.target" | sudo tee "$INSTALL_DIR/$SERVICE_NAME.service" > /dev/null

# Reload systemd
sudo systemctl daemon-reload

# Enable and start the service
sudo systemctl enable $SERVICE_NAME
sudo systemctl start $SERVICE_NAME

echo "Service $SERVICE_NAME installed and started successfully."
