專案背景

在java專案部署程序中，由于內外部各種因素，可能會遇到一些感覺操作不便捷的場景，例如

jar包未隨系統自動啟動需要每次手動重啟
系統vpn堡壘機多重防御更新繁瑣
系統無圖形化界面命令列操作復雜
等等......

在作業中之前也總結了windows的Jar包部署工具與linux下的jar包自動化部署腳本，這次就想著否能將二者統一結合，本著簡單/高效/功能專一的原則，做出一

個可視化jar包部署平臺，JarManage應運而生

功能介紹

專案地址：https://gitee.com/code2roc/jar-manage

支持在線創建專案，上傳Jar包，自動備份，配置啟動引數，注冊系統服務，查看啟動日志等功能，具有以下優點

基于servlet開發，依賴簡潔，部署包10MB左右
結合嵌入式tomcat一鍵部署，無外部容器依賴
使用h2db存盤資料，無外部資料庫依賴
適配windows/linux平臺，滿足多種環境
具體專案經平臺部署后自動注冊系統服務，無需擔心服務器重啟

系統架構圖如下

技術分析

平臺識別

首先通過系統os識別是windows平臺還是linux平臺

String os = System.getProperty("os.name").toLowerCase();
if (os.startsWith("win")) {
   platform = DepolyPlatform.Windows;
}

通過system-release檔案識別部分基于CentOS開發的Linux系統

String command = "cat /etc/system-release";
String result = CMDUtil.executeLinuxCommand(command);
if (result.startsWith("Red Hat")) {
   platform = DepolyPlatform.LinuxRedHat;
} else if (result.startsWith("CentOS")) {
   platform = DepolyPlatform.LinuxCentOS;
} else if (result.startsWith("openEuler")) {
   platform = DepolyPlatform.LinuxOpenEuler;
}

通過issue檔案識別部分基于Ubuntu/Debian開發的Linux系統

command = "cat /etc/issue";
result = CMDUtil.executeLinuxCommand(command);
if (!StringUtil.isEmpty(result)) {
  if (result.startsWith("Ubuntu")) {
     platform = DepolyPlatform.LinuxUbuntu;
} else if (result.startsWith("Debian")) {
      platform = DepolyPlatform.LinuxDebian;
   }
}

windows注冊服務

通過sc query命令判斷服務狀態

    public String getStatus(String serviceName) {
        String status = DepolyStatus.UnInstall;
        try {
            String command = "sc query " + serviceName;
            String commandResultFilePath = CMDUtil.executeWindowCommandStoreFile(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(commandResultFilePath)));
            String line = reader.readLine();
            while (line != null) {
                if (line.trim().startsWith("STATE")) {
                    if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("1"))
                        status = DepolyStatus.Stopped;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("2"))
                        status = DepolyStatus.Startting;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("3"))
                        status = DepolyStatus.Stopping;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("4"))
                        status = DepolyStatus.Running;
                }
                line = reader.readLine();
            }
        } catch (IOException e) {
            LogUtil.error(e);
        }
        return status;
    }

通過winsw這個開源專案配置exe和xml檔案將jar包注冊為windows服務，專案地址：https://github.com/winsw/winsw/

linux注冊服務

通過systemctl status命令判斷服務狀態

    public String getStatus(String serviceName) {
        String status = DepolyStatus.UnInstall;
        try {
            String command = "systemctl status " + serviceName;
            String commandResultFilePath = CMDUtil.executeLinuxCommandWithStore(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(commandResultFilePath)));
            String line = reader.readLine();
            while (line != null) {
                if (line.trim().startsWith("Active")) {
                    if (line.trim().indexOf("inactive (dead)") > 0)
                        status = DepolyStatus.Stopped;
                    else if (line.trim().indexOf("active (running)") > 0)
                        status = DepolyStatus.Running;
                    else if (line.trim().indexOf("failed") > 0)
                        status = DepolyStatus.Stopped;
                }
                line = reader.readLine();
            }
        } catch (IOException e) {
            LogUtil.error(e);
        }
        return status;
    }

通過拷貝service檔案到systemd/system目錄下注冊linux服務
