部署jdk

ls

tar xf jdk-8u171-linux-x64.tar.gz -C /usr/local

cd /usr/local

mv jdk1.8.0_171 jdk

ln -s /usr/local/jdk/bin/java /usr/local/bin

java -version

 

部署java环境变量

 

1. sed -i.ori '$a export JAVA_HOME=/usr/local/jdk\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\nexport CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar' /etc/profile

tail -3 /etc/profile

source /etc/profile

 

部署maven

ls

tar xf apache-maven-3.5.0-bin.tar.gz -C /usr/local/

cd /usr/local

mv apache-maven-3.5.0 maven

ln -s /usr/local/maven/bin/mvn /usr/local/bin

mvn -version

 

部署maven环境变量

vim /etc/profile

 

1. export MAVEN_HOME=/usr/local/maven
2. export PATH=$PATH:${MAVEN_HOME}

tail -2 /etc/profile

source /etc/profile

 

部署tomcat

ls

tar xf apache-tomcat-8.5.31.tar.gz -C /usr/local/

cd /usr/local

mv apache-tomcat-8.0.27 tomcat

cd tomcat

rm -rf webapps/*

ls webapps/

 

部署tomcat环境变量

echo 'export TOMCAT_HOME=/usr/local/tomcat' >> /etc/profile

tail -1 /etc/profile

source /etc/profile

 

自动部署需要解压maven构建后的war包，因此需要安装unzip

yum -y install unzip

which unzip

 

自动部署需要git远程仓库代码，因此需要安装git

yum -y install git

which git

 

构建一个B-JAVA流水线项目的提前准备工作

 

在Git服务器上创建用于存放solo源代码的仓库

hostname -I

cd /home/git/repos

mkdir solo.git

cd solo.git

git --bare init

cd ..

chown -R git.git solo.git

 

在jenkins服务器上进行解压solo.tar.gz

链接：https://pan.baidu.com/s/1Fui3TNCwEsmv4TeUZ0fiWA 
提取码：tjo6 --->solo源代码

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

 

为了最后的测试，我们需要修改源代码的一个配置文件

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服务器IP地址
2. 31 serverPort=8080 --->监听端口

 

将solo源代码提交到git仓库

cd /mycode/solo

git add *

git commit -m "第一次提交"

git push -u origin master

 

将代码克隆到本地进行克隆验证

cd /test

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

cd solo

ls

 

在jenkins服务器上创建一个流水线脚本并提交git远程仓库（构建B-JAVA的时候生成过脚本）

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
4. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
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'
25. }
26. }

 

在jenkins网页上创建tomcat服务器的节点信息

http://192.168.200.91:8080

---

---

---

 

构建一个B-JAVA流水线项目(有上文生成的脚本信息)

http://192.168.200.91:8080

---

---

---

 

推送本地仓库到远程git

git add *

git commit -m "java流水线脚本"

git push -u origin master

 

在B-JAVA立即构建并测试

---

 

在tomcat服务器上查看tomcat服务并在浏览器查看测试结果

ss -antup | grep 8080

http://192.168.200.104:8080

---

 

如果进行流水线的单Slave从节点分布式构建测试(出现tomcat服务未启动情况)

如果构建会失败在最后一步（tomcat进程未启动） 
jenkins没办法启动tomcat的socker进程 
原因在于Pipeline流水线在启动一个脚本程序的时候，这个脚本程序会运行在后台。 
但是当Pipeline结束以后，jenkins会自动kill掉所有和Pipeline有关的派生子进程 
因此，我们需要在流水线脚本里加一个变量参数，不让Pipeline杀掉才可以 
JENKINS_NODE_COOKIE=dontkillme

 

在jenkins服务器上重新克隆远程仓库代码

cd /jenkinsfile

rm -rf *

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

ls

cd /jenkinsfile

ls

 

修改jenkins服务器上的流水线脚本

cd /jenkinsfile/jenkinsfile/

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
4. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
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 '''
14. JENKINS_NODE_COOKIE=dontkillme
15. WWWROOT=/usr/local/tomcat/webapps/ROOT
16. [ -d /data/backup ] || mkdir -p /data/backup
17. if [ -d $WWWROOT ];then
18. mv $WWWROOT /data/backup/tomcat-$(date +%F_%T)
19. fi
20. unzip ${WORKSPACE}/target/*.war -d $WWWROOT
21. PID=$(ps -ef | grep tomcat | egrep -v "grep|$$" | awk '{print $2}')
22. [ -n "$PID" ] && kill -9 $PID
23. /bin/bash /usr/local/tomcat/bin/startup.sh'''
24. }
25. stage('test') {
26. sh 'echo susses'
27. }
28. }

 

推送本地仓库到远程git

git add *

git commit -m "java-流水线脚本"

git push -u origin master

 

在B-JAVA立即构建并测试

---

 

在tomcat服务器上查看进程并浏览器上查看测试结果

ss -antup | grep 8080 --->不添加内段话，流水线脚本默认杀掉tomcat服务

http://192.168.200.104:8080

让ssh支持流水线，需要安装插件SSH Pipeline Steps

流水线ssh方式的脚本详解

 

1. def remote = [:] #定义变量不需要改
2. remote.name = 'test' #远程主机的名字
3. remote.host = 'test.domain.com' #远程主机的IP
4. remote.user = 'root' #远程主机的用户
5. remote.password = 'password' #远程主机的密码
6. remote.allowAnyHosts = true #照着超就可以
7. stage('Remote SSH') { #阶段名称
8. writeFile file: 'abc.sh', text: 'ls -lrt' #把后面的命令,让如abc.sh脚本里
9. sshScript remote: remote, script: "abc.sh" #把脚本分发自定义的主机
10. }

 

在浏览器进入jenkins主用户来添加新节点信息（有几点节点就添加几个）

 

流水线ssh方式的脚本内容(一个节点给多台发送SSH脚本)

 

1. node ("JAVA-slave1-192.168.200.104"){
2. //def mvnHome

4. stage('checkout') { // for display purposes
5. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
6. doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [],
7. userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
8. url: 'git@192.168.200.70:/home/git/repos/solo.git']]])
9. }
10. stage('maven build') {
11. sh '/usr/local/maven/bin/mvn clean package -Dmaven.test.skip=true'
12. }
13. stage('Remote ssh 200.104') {
14. remote.name = 'test'
15. remote.user = '192.168.200.104'
16. remote.user = 'root'
17. remote.password = 'linyaonie'
18. remote.allowAnyHosts = true
19. writeFile file: '104.sh',text:'''
20. echo "`hostname -I`"
21. '''
22. sshScript remote: remote,script: "104.sh"
23. }
24. stage('Remote ssh 200.xxx') {
25. remote.name = 'test'
26. remote.user = '192.168.200.xxx'
27. remote.user = 'root'
28. remote.password = 'linyaonie'
29. remote.allowAnyHosts = true
30. writeFile file: 'xxx.sh',text:'''
31. echo "`hostname -I`"
32. '''
33. sshScript remote: remote,script: "xxx.sh"
34. }
35. }

 

重新把新修过的内容添加到远程仓库并构建测试在查看logs日志的结果

git add *

git commit -m "测试SSH"

git push -u origin master

 

流水线项目发布多节点需要注意的事项

 

多节点流水线脚本内容（多个节点）

 

1. node ("JAVA-slave1-192.168.200.104"){
2. //def mvnHome
3. stage('checkout') { // for display purposes
4. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
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. }

18. mv $WWWROOT /data/backup/tomcat-$(date +%F_%T)
19. fi
20. unzip ${WORKSPACE}/target/*.war -d $WWWROOT
21. PID=$(ps -ef | grep tomcat | egrep -v "grep|$$" | awk '{print $2}')
22. [ -n "$PID" ] && kill -9 $PID

30. node ("JAVA-slave2-192.168.200.xxx"){
31. //def mvnHome
32. stage('checkout') { // for display purposes
33. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
34. doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [],
35. userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
36. url: 'git@192.168.200.70:/home/git/repos/solo.git']]])
37. }
38. stage('maven build') {
39. sh '/usr/local/maven/bin/mvn clean package -Dmaven.test.skip=true'
40. }
41. stage('deploy') {
42. sh '''
43. JENKINS_NODE_COOKIE=dontkillme
44. WWWROOT=/usr/local/tomcat/webapps/ROOT
45. [ -d /data/backup ] || mkdir -p /data/backup
46. if [ -d $WWWROOT ];then
47. mv $WWWROOT /data/backup/tomcat-$(date +%F_%T)
48. fi
49. unzip ${WORKSPACE}/target/*.war -d $WWWROOT
50. PID=$(ps -ef | grep tomcat | egrep -v "grep|$$" | awk '{print $2}')
51. [ -n "$PID" ] && kill -9 $PID

53. }
54. stage('test') {
55. sh 'echo susses'
56. }
57. }

 

假如是克隆的机器需要把hosts文件里的映射修改一下

 

在浏览器进入jenkins主用户来添加新节点信息（有几点节点就添加几个）

 

重新把新修过的内容添加到远程仓库并构建测试在查看logs日志的结果

git add *

git commit -m "测试SSH"

git push -u origin master
