一、運行Jenkins部署任務

• 1. 執行Jenkins部署任務
• 2. 打開瀏覽器訪問部署應用程序
• 3. 確定發布結果的正確性
• 4. 確認執行結果成功

• 2. 打開瀏覽器訪問部署應用程序
  • 瀏覽器訪問：http://192.168.45.145:8090/
    
    現在成功部署成功了！！！！
• 3. 確定發布結果的正確性
• 4. 確認執行結果成功

本章回顧

本章講述了

• 典型的自動化部署任務過程
• 并實際創建了一個Jenkins自動化部署任務開發中的一些要素
• 實際執行自動化部署任務
  通過這個任務，我們可以看到測試環境被自動化的創建了出來。有了這個任務我么嘗試一下，實戰環節。
  在實戰中我們實際體驗一下如何達到開發修改代碼，推送遠程github倉庫，測試一鍵部署測試環境
  
• 附上：deploy.sh腳本內容：

#!/usr/bin/env bash #編譯+部署order站點#需要配置如下參數 # 項目路徑, 在Execute Shell中配置項目路徑, pwd 就可以獲得該項目路徑 # export PROJ_PATH=這個jenkins任務在部署機器上的路徑# 輸入你的環境上tomcat的全路徑 # export TOMCAT_APP_PATH=tomcat在部署機器上的路徑### base 函數 killTomcat() {pid=`ps -ef|grep tomcat|grep java|awk '{print $2}'`echo "tomcat Id list :$pid"if [ "$pid" = "" ]thenecho "no tomcat pid alive"elsekill -9 $pidfi } cd $PROJ_PATH/order mvn clean install# 停tomcat killTomcat# 刪除原有工程 rm -rf $TOMCAT_APP_PATH/webapps/ROOT rm -f $TOMCAT_APP_PATH/webapps/ROOT.war rm -f $TOMCAT_APP_PATH/webapps/order.war# 復制新的工程 cp $PROJ_PATH/order/target/order.war $TOMCAT_APP_PATH/webapps/cd $TOMCAT_APP_PATH/webapps/ mv order.war ROOT.war# 啟動Tomcat cd $TOMCAT_APP_PATH/ sh bin/startup.sh
