一個用于運行 Java SpringBoot 的 Linux 腳本 run.sh
- 自動根據(jù)所在目錄獲取最新的可執(zhí)行 jar盟迟、war
- 自動使用環(huán)境變量 JAVA_HOME 進行執(zhí)行命令（可配置）
- 支持優(yōu)雅下線（默認等待60秒秋泳，可配置，如果超過60秒則強制下線）
- 支持監(jiān)聽 SpringBoot 上線狀態(tài)
- 支持添加自定義運行參數(shù)（如：JVM 參數(shù)攒菠、SpringBoot 參數(shù)）
- 支持常用功能：啟動迫皱、停止、重啟辖众、查看狀態(tài)卓起、查看日志
- SpringBoot 項目支持查看應用端口信息
目錄結(jié)構(gòu)如下
├── fastboot-0.0.1.jar # 應用jar
├── logs
│ ├── console.log # 應用控制臺輸入的日志
│ └── server.pid # 應用的pid
└── run.sh # 執(zhí)行腳本
可配置的參數(shù)
1. 用法
添加文件的執(zhí)行權(quán)限
# 首次執(zhí)行第一次即可
chmod +x run.sh
重啟并清空日志
查看狀態(tài)
啟動
停止
2. 說明
# 賦予執(zhí)行權(quán)限(初始化執(zhí)行一次)
chmod +x run.sh
# 啟動應用程序
sh run.sh start
# 停止應用程序
sh run.sh stop
# 查看應用程序
# sh run.sh status
# 重啟應用程序
sh run.sh restart c # 加 c 刪除歷史日志文件
# 查看應用日志
sh run.sh logs
3. 源碼(run.sh)
#!/bin/bash
#
# ================================================ 說明 start ================================================
# 1. 賦予執(zhí)行權(quán)限: chmod +x run.sh
# 2. 啟動應用程序: sh run.sh start
# 3. 停止應用程序: sh run.sh stop
# 4. 查看應用程序: sh run.sh status
# 5. 重啟應用程序: sh run.sh restart c # 加 c 刪除歷史日志文件
# 6. 查看應用日志: sh run.sh logs
