【Linux】Jenkins以war包運行及開機啓動配置（四）

　　本例介紹jenkins已war包運行及開機啓動配置

　　環境：Linux環境（CentOS 7.4）

以war包運行

　　一、下載jenkins.war包

　　二、啓動war包（ 默認端口：8080，默認JENKINS_HOME目錄：～/.jenkins ）

　　　　前臺啓動命令：java -jar jenkins.war

　　　　後臺啓動命令：nohup java -jar jenkins.war &

　　三、使用瀏覽器打開地址：http://ip:8080，便可訪問到jenkins

　　　　關閉jenkins，頁面訪問地址：http://ip:8080/exit

　　　　重啓jenkins，頁面訪問地址：http://ip:8080/restart

　　四、其餘安裝參考【Linux】Jenkins安裝（一）

　　五、修改JENKINS_HOME目錄啓動，須要新建一個腳本jenkins.sh，而後運行腳本　

1 #!/bin/bash
2 # 導入JENKINS_HOME環境變量
3 export JENKINS_HOME=/data/soft/jenkins
4 
5 cd $JENKINS_HOME
6 
7 # 啓動Jenkins
8 nohup java -jar jenkins.war  --ajp13Port=-1 --httpPort=18080 >/dev/null 2>&1 &

　　六、構建shell，demo以下：

 1 #!/bin/bash
 2 # 編譯+部署zeus站點
 3 
 4 # 保持Jenkins啓動的Service（tomcat） 不被殺死
 5 export BUILD_ID=dontKillMe
 6 
 7 # 須要配置以下參數
 8 # 項目路徑，在Execute Shell中國配置項目路徑， pwd 就能夠得到項目路徑
 9 # export PROJ_PATH=這個jenkins任務在部署機器上的路徑
10 export PROJ_PATH=`pwd`
11 
12 # 輸入你在環境上tomcat的全路徑
13 # export TOMCAT_APP_PATH=tomcat在部署機器上的路徑
14 export TOMCAT_APP_PATH=/data/soft/apache-tomcat-8080
15 
16 
17 ### base 函數
18 killTomcat()
19 {
20     pid=`ps -ef | grep tomcat-8080 | grep -v grep | awk '{print $2}'` 
21     echo "Tomcat Id is : $pid"
22     if [ ! -n "$pid" ];
23     then
24         echo "No Tomcat Pid alive"
25     else 
26         echo "Tomcat Pid alive"
27     fi
28 }
29 
30 cd $PROJ_PATH/god-site
31 pwd
32 
33 mvn clean package
34 
35 # 停tomcat
36 killTomcat
37 
38 # 刪除原有工程
39 rm -rf $TOMCAT_APP_PATH/webapps/zeus.war
40 
41 # 複製新的工程
42 cp $PROJ_PATH/god-site/god-web/god-web-zeus/target/zeus.war $TOMCAT_APP_PATH/webapps/
43 
44 # 啓動Tomcat
45 cd $TOMCAT_APP_PATH
46 sh bin/startup.sh

　　補充：

　　使用java -jar 命令的時候能夠加入啓動參數，啓動命令格式：java -jar jenkins.war [--option=value] [--option=value]，

　　到達一些配置效果，例如：

　　　　修改jenkins端口啓動命令：java -jar jenkins.war --httpPort=18080

　　其餘啓動參數查看命令：java -jar jenkins.war --help

 開機啓動配置

　　參考：【Linux】開機自動啓動腳本

　　一、編寫啓動腳本jenkins

　　　　命令：vim /data/soft/jenkins/jenkins.sh

 1 #!/bin/bash 
 2 
 3 # 導入環境變量 
 4 export JENKINS_HOME=/data/soft/jenkins 
 5 export JAVA_HOME=/data/soft/jdk1.8.0_181
 6 
 7 cd $JENKINS_HOME 
 8 
 9 pid=`ps -ef | grep jenkins.war | grep -v 'grep'| awk '{print $2}'`    
10   if [ "$1" = "start" ];then 
11   if [ -n "$pid" ];then
12   echo 'jenkins is running...' 
13 else 
14   ### java啓動服務 配置java安裝根路徑,和啓動war包存的根路徑
15   nohup $JAVA_HOME/bin/java  -Xms128m -Xmx256m   -jar $JENKINS_HOME/jenkins.war  --ajp13Port=-1 --httpPort=18080 >/dev/null 2>&1 &
16   fi
17   elif [ "$1" = "stop" ];then
18   exec ps -ef | grep jenkins | grep -v grep | awk '{print $2}'| xargs kill -9 
19   echo 'jenkins is stop...'
20 else
21   echo "Please input like this:"./jenkins.sh start" or "./jenkins stop""  
22   fi 

　　二、給jenkins.sh文件受權

　　　　命令：chmod +x /data/soft/jenkins/jenkins.sh

　　三、在/etc/rc.d/rc.local文件底部，添加內容：

1 # jenkins              
2 /data/soft/jenkins/jenkins.sh start 

　　四、重啓計算機

　　　　命令：reboot

 Jenkins經常使用功能

　　一、備份、遷移、恢復jenkins

　　首先找到JENKINS_HOME，由於Jenkins的全部的數據都是以文件的形式存放在JENKINS_HOME目錄中。無論是遷移仍是備份，只須要操做JENKINS_HOME就好了。

　　遷移：建議將JENKINS_HOME打包後在拷貝，windows能夠用zip，rar等，Linux有zip，tar等，而後將打包的文件解壓到新的JENKINS_HOME目錄就好了。

　　備份：若是是臨時備份，整個壓縮文件就好了。

　　恢復：恢復的時候須要先中止jenkins。

　　二、升級Jenkins

　　Jenkins的開發迭代很是快，每週發佈一個開發版本，長期支持版每半年更新一次(ps:大版本更新)。如此頻繁的更新，怎麼升級呢？

　　war：下載新版的war文件，替換舊版本war文件。重啓便可。

　　二進制：卸載舊版本，安裝新版本便可。
