一、實戰專案介紹- JeeSite
- 基於Spring Boot 2.0
- 資料儲存MySQL
- 語言:Java
- 規模大小:適中,適合初學者
原始碼地址:https://gitee.com/thinkgem/jeesite4 ,感謝原作者
本次專案演練地址:https://gitee.com/sfboy/iJeeSite4 ,在原作者的專案上,增加了Pipline持續整合的指令碼,便於實戰使用
二、環境準備
Spring Boot專案執行配置:MySQL+Java+Maven
MySQL安裝參考:https://www.cnblogs.com/feng0815/p/14041558.html
Maven安裝參考: https://www.cnblogs.com/feng0815/p/14354226.html
Java安裝參考:自行百度。。
三、專案配置、除錯、執行
3.1 初始化
- 開啟 JeeSite4/web/src/main/resources/config/application.yml,填寫資料庫配置(地址、IP埠、使用者名稱、密碼)
- 進入專案路徑 JeeSite4/web/bin,執行初始化指令碼程式init-data.sh(Windows下執行init-data.bat)
初始化指令碼用來建立初始資料,初始化前要保證資料庫中有jeesite資料庫,否則會造成無法連線jeesite資料庫,初始化失敗
開始執行
執行結束
3.2 配置專案
3.2.1 使用IDE編譯
- 新增JeeSite4/root/pom.xml Maven根節點到IDE的maven view中,其餘依賴module會根據配置一起匯入
Maven編譯、打包
在Maven view 中選中JeeSite Root下Lifecycle中的clean + install,然後單擊執行按鈕
3.2.2 在命令列編譯
進入到JeeSite4/root目錄下,執行mvn clean install
3.3 執行專案demo
3.3.1 在IDE執行
展開JeeSite Web → Plugins → spring-boot → spring-boot:run ,單擊執行
執行成功
訪問專案:http://localhost:8980/a/login
輸入使用者名稱system,密碼admin,點選登入
3.3.2 在命令列執行
進入到JeeSite4/web目錄下,執行:mvn clean spring-boot:run -Dmaven.test.skip=true
(Dmaven.test.skip=true,不執行單元測試)
執行成功
四、Tomcat部署持續互動實戰
4.1 Tomcat執行和配置入門
下載,官網:https://tomcat.apache.org/
直接解壓到安裝目錄即可
Tomcat基本配置
- 啟動:bin/startup.sh
- 停止:bin/shutdown.sh
- 配置檔案:conf/server.xml(配置埠號)
- 日誌:logs/catalina.out
4.2 使用Jenkins Pipline任務部署Spring應用到Tomcat
4.2.1 Jenkins引數配置,設定Pipline指令碼中所需的引數
建立Jenkins Pipline任務
設定程式碼分支,預設分支為master
4.2.2 配置Pipline指令碼
執行,構建任務
構建成功,開啟專案頁面:http://localhost:8080/a/login
Pipline程式碼如下(Scripted Pipeline):
node('master') {
stage('同步原始碼') {
git([url: 'https://gitee.com/sfboy/iJeeSite4.git', branch: '${branch}'])
}
stage('maven編譯打包') {
sh '''
. ~/.bash_profile
export pwd=`pwd`
export os_type=`uname`
cd web/src/main/resources/config
if [[ "${os_type}" == "Darwin" ]]; then
sed -i "" "s/mysql_ip/${mysql_ip}/g" application.yml
sed -i "" "s/mysql_port/${mysql_port}/g" application.yml
sed -i "" "s/mysql_user/${mysql_user}/g" application.yml
sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application.yml
else
sed -i "s/mysql_ip/${mysql_ip}/g" application.yml
sed -i "s/mysql_port/${mysql_port}/g" application.yml
sed -i "s/mysql_user/${mysql_user}/g" application.yml
sed -i "s/mysql_pwd/${mysql_pwd}/g" application.yml
fi
cd $pwd/root
mvn clean install -Dmaven.test.skip=true
cd $pwd/web
mvn clean package spring-boot:repackage -Dmaven.test.skip=true -U
'''
}
stage('停止 tomcat') {
sh '''
## 停止tomcat的函式, 引數$1帶入tomcat的路徑$TOMCAT_PATH
killTomcat()
{
pid=`ps -ef|grep $1|grep java|awk '{print $2}'`
echo "tomcat Id list :$pid"
if [ "$pid" = "" ]
then
echo "no tomcat pid alive"
else
kill -9 $pid
fi
}
## 停止Tomcat
killTomcat $tomcat_home
'''
}
stage('清理環境') {
sh '''
## 刪除原有war包
rm -f $tomcat_home/webapps/ROOT.war
rm -rf $tomcat_home/webapps/ROOT
'''
}
stage('部署新的war包') {
sh '''
cp web/target/web.war $tomcat_home/webapps/
cd $tomcat_home/webapps
mv web.war ROOT.war
'''
}
stage('啟動tomcat') {
sh '''
JENKINS_NODE_COOKIE=dontkillme
cd $tomcat_home/bin
sh startup.sh
'''
}
}
五、docker部署持續互動實戰
Pipline指令碼(Declarative Pipeline)
pipeline {
agent {
label 'master'
}
environment {
docker_image_name = 'jeesite4'
docker_container_name = 'iJeesite4'
PATH = "/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"
}
parameters {
string(name: 'branch', defaultValue: 'master', description: 'Git branch')
}
stages{
stage('同步原始碼') {
steps {
git url:'https://gitee.com/sfboy/iJeeSite4.git', branch:'$branch'
}
}
stage('設定配置檔案'){
steps{
sh '''
. ~/.bash_profile
export os_type=`uname`
cd ${WORKSPACE}/web/bin/docker
if [[ "${os_type}" == "Darwin" ]]; then
sed -i "" "s/mysql_ip/${mysql_docker_ip}/g" application-prod.yml
sed -i "" "s/mysql_port/${mysql_port}/g" application-prod.yml
sed -i "" "s/mysql_user/${mysql_user}/g" application-prod.yml
sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application-prod.yml
else
sed -i "s/mysql_ip/${mysql_docker_ip}/g" application-prod.yml
sed -i "s/mysql_port/${mysql_port}/g" application-prod.yml
sed -i "s/mysql_user/${mysql_user}/g" application-prod.yml
sed -i "s/mysql_pwd/${mysql_pwd}/g" application-prod.yml
fi
'''
}
}
stage('Maven 編譯'){
steps {
sh '''
. ~/.bash_profile
cd ${WORKSPACE}/root
mvn clean install -Dmaven.test.skip=true
cd ${WORKSPACE}/web
mvn clean package spring-boot:repackage -Dmaven.test.skip=true -U
'''
}
}
stage('停止 / 刪除 現有Docker Container/Image '){
steps {
script{
try{
sh 'docker stop $docker_container_name'
}catch(exc){
echo "The container $docker_container_name does not exist"
}
try{
sh 'docker rm $docker_container_name'
}catch(exc){
echo "The container $docker_container_name does not exist"
}
try{
sh 'docker rmi $docker_image_name'
}catch(exc){
echo "The docker image $docker_image_name does not exist"
}
}
}
}
stage('生成新的Docker Image'){
steps {
sh '''
. ~/.bash_profile
cd ${WORKSPACE}/web/bin/docker
rm -f web.war
cp ${WORKSPACE}/web/target/web.war .
docker build -t $docker_image_name .
'''
}
}
stage('啟動新Docker例項'){
steps {
sh '''
docker run -d --name $docker_container_name -p 8981:8980 $docker_image_name
'''
}
}
}
}
六、生產與測試環境分離持續互動實戰
需要在Pipline指令碼中區分環境,具體指令碼如下
pipeline {
agent {
label 'master'
}
environment {
docker_image = 'jeesite4'
docker_container = 'iJeesite4'
PATH = "/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"
}
parameters {
string(name: 'branch', defaultValue: 'master', description: 'Git branch')
choice(name: 'env', choices: ['prod', 'qa'], description: 'Environment Type')
}
stages{
stage('同步原始碼') {
steps {
git url:'https://gitee.com/sfboy/iJeeSite4.git', branch:'${branch}'
}
}
stage('設定配置檔案'){
steps{
sh '''
. ~/.bash_profile
if [[ "${env}" == "prod" ]]; then
export mysql_ip=${mysql_prod_ip}
export mysql_port=${mysql_prod_port}
else
export mysql_ip=${mysql_qa_ip}
export mysql_port=${mysql_qa_port}
fi
export os_type=`uname`
cd ${WORKSPACE}/web/bin/docker
if [[ "${os_type}" == "Darwin" ]]; then
sed -i "" "s/mysql_ip/${mysql_ip}/g" application-${env}.yml
sed -i "" "s/mysql_port/${mysql_port}/g" application-${env}.yml
sed -i "" "s/mysql_user/${mysql_user}/g" application-${env}.yml
sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application-${env}.yml
sed -i "" "s/<env>/${env}/g" Dockerfile-param
else
sed -i "s/mysql_ip/${mysql_ip}/g" application-${env}.yml
sed -i "s/mysql_port/${mysql_port}/g" application-${env}.yml
sed -i "s/mysql_user/${mysql_user}/g" application-${env}.yml
sed -i "s/mysql_pwd/${mysql_pwd}/g" application-${env}.yml
sed -i "s/<env>/${env}/g" Dockerfile-param
fi
'''
}
}
stage('Maven 編譯'){
steps {
sh '''
. ~/.bash_profile
cd ${WORKSPACE}/root
mvn clean install -Dmaven.test.skip=true
cd ${WORKSPACE}/web
mvn clean package spring-boot:repackage -Dmaven.test.skip=true -U
'''
}
}
stage('停止 / 刪除 現有Docker Container/Image '){
steps {
script{
try{
sh 'docker stop $docker_container-$env'
}catch(exc){
echo "The container $docker_container-${params.env} does not exist"
}
try{
sh 'docker rm $docker_container-$env'
}catch(exc){
echo "The container $docker_container-${params.env} does not exist"
}
try{
sh 'docker rmi $docker_image-$env'
}catch(exc){
echo "The docker image $docker_image-${params.env} does not exist"
}
}
}
}
stage('生成新的Docker Image'){
steps {
sh '''
cd ${WORKSPACE}/web/bin/docker
rm -f web.war
cp ${WORKSPACE}/web/target/web.war .
docker build -t $docker_image-$env -f Dockerfile-param .
'''
}
}
stage('啟動新Docker例項'){
steps {
sh '''
if [[ "$env" == "prod" ]]; then
export port="8888"
else
export port="8811"
fi
docker run -d --name $docker_container-$env -p $port:8980 $docker_image-$env
'''
}
}
}
}

在Jenkins中配置好Pipline指令碼中所需的MySQL變數資訊
建立Pipline任務,設定Pipline指令碼
由於我們第一次執行時,指令碼里的parameter引數無法同步到Jenkins是裡,所以第一次執行會報錯,當我們重新整理頁面是就會發現引數已經同步了
然後我們選擇測試環境,再次build即可
build完成
開啟測試環境:http://127.0.0.1:8811/a/login
然後我們再build成產環境
build完成
開啟成產環境:http://localhost:8888/a/login
檢視生產環境和測試環境的docker容器
ok,完結,撒花~~
