構建一個B-JAVA流水線項目的提前准備工作

 

在Git服務器上創建用於存放solo源代碼的倉庫

hostname -I

cd /home/git/repos

mkdir solo.git

cd solo.git

git --bare init

cd ..

chown -R git.git solo.git

image_1cvnjl79lgpf1r9l1gtec3k1ftd5r.png-60.6kB

 

在jenkins服務器上進行解壓solo.tar.gz

鏈接：https://pan.baidu.com/s/1Fui3TNCwEsmv4TeUZ0fiWA 
提取碼：tjo6 --->solo源代碼

ls

tar xf solo.tar.gz

mkdir -p /mycode

cd /mycode

git clone git@192.168.200.70:/home/git/repos/solo.git

ls

cd solo

mv /root/solo/* .

ls

image_1cvnjnrup1cu21inj1lut1b9pfv068.png-63.6kB

 

為了最后的測試，我們需要修改源代碼的一個配置文件

ls

cd src/main/resources

cat -n latke.properties | sed -n '29p;31p'

vim latke.properties +29

cat -n latke.properties | sed -n '29p;31p'

 
  1. 29 serverHost=192.168.200.104 --->tomcat服務器IP地址
  2. 31 serverPort=8080 --->監聽端口

image_1cvnk1jm51k6g6ch1mu0efmq196l.png-45.1kB

 

將solo源代碼提交到git倉庫

cd /mycode/solo

git add *

git commit -m "第一次提交"

git push -u origin master

image_1cvnke1j5vhf175ts2ql1o1pb672.png-171kB

 

將代碼克隆到本地進行克隆驗證

cd /test

git clone git@192.168.200.70:/home/git/repos/solo.git

cd solo

ls

image_1cvnkf9mm1gm0173f1hq51ros1oq77f.png-60.5kB

 

在jenkins服務器上創建一個流水線腳本並提交git遠程倉庫（構建B-JAVA的時候生成過腳本）

mkdir /jenkinsfile

cd /jenkinsfile

git clone git@192.168.200.70:/home/git/repos/jenkinsfile

ls

cd jenkinsfile

mkdir itemB

vim itemB/jenkinsfile-java-solo

cat itemB/jenkinsfile-java-solo

 
  1. node ("JAVA-slave1-192.168.200.104"){
  2. //def mvnHome
  3. stage('checkout') { // for display purposes

  5. doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [],
  6. userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
  7. url: 'git@192.168.200.70:/home/git/repos/solo.git']]])
  8. }
  9. stage('maven build') {
  10. sh '/usr/local/maven/bin/mvn clean package -Dmaven.test.skip=true'
  11. }
  12. stage('deploy') {
  13. sh '''WWWROOT=/usr/local/tomcat/webapps/ROOT
  14. [ -d /data/backup ] || mkdir -p /data/backup
  15. if [ -d $WWWROOT ];then
  16. mv $WWWROOT /data/backup/tomcat-$(date +%F_%T)
  17. fi
  18. unzip ${WORKSPACE}/target/*.war -d $WWWROOT
  19. PID=$(ps -ef | grep tomcat | egrep -v "grep|$$" | awk '{print $2}')
  20. [ -n "$PID" ] && kill -9 $PID
  21. /bin/bash /usr/local/tomcat/bin/startup.sh'''
  22. }
  23. stage('test') {
  24. sh 'echo susses'

構建一個B-JAVA流水線項目(有上文生成的腳本信息)

推送本地倉庫到遠程git

在tomcat服務器上查看tomcat服務並在瀏覽器查看測試結果

ss -antup | grep 8080

http://192.168.200.104:8080

image_1cvnt2ah31mev1jlf1p911ubng4ohq.png-62.3kB

 

如果進行流水線的單Slave從節點分布式構建測試(出現tomcat服務未啟動情況)

如果構建會失敗在最后一步（tomcat進程未啟動） 
jenkins沒辦法啟動tomcat的socker進程 
原因在於Pipeline流水線在啟動一個腳本程序的時候，這個腳本程序會運行在后台。 
但是當Pipeline結束以后，jenkins會自動kill掉所有和Pipeline有關的派生子進程 
因此，我們需要在流水線腳本里加一個變量參數，不讓Pipeline殺掉才可以 
JENKINS_NODE_COOKIE=dontkillme

 

在jenkins服務器上重新克隆遠程倉庫代碼

cd /jenkinsfile

rm -rf *

git clone git@192.168.200.70:/home/git/repos/jenkinsfile

ls

cd /jenkinsfile

ls

image_1cvnqcmrrqdbadf1o245fon5dl.png-54.2kB

流水線ssh方式的腳本詳解

 
  1. def remote = [:] #定義變量不需要改
  2. remote.name = 'test' #遠程主機的名字
  3. remote.host = 'test.domain.com' #遠程主機的IP
  4. remote.user = 'root' #遠程主機的用戶
  5. remote.password = 'password' #遠程主機的密碼
  6. remote.allowAnyHosts = true #照着超就可以
  7. stage('Remote SSH') { #階段名稱
  8. writeFile file: 'abc.sh', text: 'ls -lrt' #把后面的命令,讓如abc.sh腳本里
  9. sshScript remote: remote, script: "abc.sh" #把腳本分發自定義的主機
