## 一：Jenkins部署

#### 1.安装插件

```shell
• Maven插件 Maven Integration plugin
• 发布插件 Deploy to container Plugin
需要安装插件如下：
安装插件Deploy to container    ---支持自动化代码部署到tomcat容器
Git 插件  可能已经安装
Maven Integration   :jenkins利用Maven编译，打包所需插件
Publish Over SSH  :通过ssh连接
```

#### 2.安装过程

系统管理--->插件管理---->可选插件--->过滤Deploy to container---->勾选--->直接安装

注意：

​		key:指的是jenkins服务器用哪个用户去远程连接程序服务器就是那个用户的私钥。（记得做免密 jenkins---> web-server)

#### 4.配置jdk，maven，git

## 二：构建发布任务

#### 1.创建maven项目

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628000510980.png" alt="image-20220628000510980" style="zoom:50%;" />

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628000547600.png" alt="image-20220628000547600" style="zoom:50%;" />

#### 2.配置项目

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628000814797.png" alt="image-20220628000814797" style="zoom:50%;" />

注意：

​		新版本需要将默认分支改为main

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628003247070.png" alt="image-20220628003247070" style="zoom:50%;" />

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628003459003.png" alt="image-20220628003459003" style="zoom:50%;" />

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628003538519.png" alt="image-20220628003538519" style="zoom:50%;" />

调用mave命令

（clean package -Dmaven.test.skip = true）

<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220628003556160.png" alt="image-20220628003556160" style="zoom:50%;" />

保存：

#### 3.发布服务器部署

```shell
[root@java-server ~]# mkdir -p /data/application
上传jdk
[root@java-server ~]# tar xzf jdk-8u191-linux-x64.tar.gz -C /usr/local/
[root@java-server ~]# cd /usr/local/
[root@java-server local]# mv jdk1.8.0_191/ java
下载tomcat
[root@java-server ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.42/bin/apache-tomcat-8.5.42.tar.gz
[root@java-server ~]# tar xzf apache-tomcat-8.5.42.tar.gz -C /data/application/
[root@java-server ~]# cd /data/application/
[root@java-server application]# mv apache-tomcat-8.5.42/ tomcat
设置环境变量
[root@java-server ~]# vim /etc/profile
export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/data/application/tomcat
[root@java-server ~]# source /etc/profile
测试:
[root@java-server ~]# java -version 
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
删除tomcat默认发布目录下面的内容:
[root@java-server ~]# rm -rf /data/application/tomcat/webapps/*
[root@java-server ~]# cd /data/application/tomcat/webapps/
[root@java-server webapps]# ls
创建目录和脚本:
[root@java-server ~]# mkdir /opt/script  #创建脚本目录
[root@java-server ~]# vim app-jenkins.sh   #创建脚本
#!/usr/bin/bash
#本脚本适用于jenkins持续集成，实现备份war包到代码更新上线！使用时请注意全局变量。
#================
#Defining variables
export JAVA_HOME=/usr/local/java
webapp_path="/data/application/tomcat/webapps"
tomcat_run="/data/application/tomcat/bin"
updata_path="/data/update/`date +%F-%T`"
backup_path="/data/backup/`date +%F-%T`"
tomcat_pid=`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`
files_dir="easy-springmvc-maven"
files="easy-springmvc-maven.war"
job_path="/root/upload"

#Preparation environment
echo "Creating related directory"
mkdir -p $updata_path
mkdir -p $backup_path

echo "Move the uploaded war package to the update 2directory"
mv $job_path/$files $updata_path

echo "========================================================="
cd /opt
echo "Backing up java project"
if [ -f $webapp_path/$files ];then
	tar czf $backup_path/`date +%F-%H`.tar.gz $webapp_path
	if [ $? -ne 0 ];then
		echo "打包失败，自动退出"
		exit 1
	else
		echo "Checking if tomcat is started"
		if [ -n "$tomcat_pid" ];then
			kill -9 $tomcat_pid
			if [ $? -ne 0 ];then
				echo "tomcat关闭失败，将会自动退出"
				exit 2
			fi
		fi
		cd $webapp_path
		rm -rf $files && rm -rf $files_dir
		cp $updata_path/$files $webapp_path
		cd /opt
		$tomcat_run/startup.sh
		sleep 5
		echo "显示tomcat的pid"
		echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
		echo "tomcat startup"
		echo "请手动查看tomcat日志。脚本将会自动退出"
	fi
else
	echo "Checking if tomcat is started"
        if [ -n "$tomcat_pid" ];then
        	kill -9 $tomcat_pid
                if [ $? -ne 0 ];then
                	echo "tomcat关闭失败，将会自动退出"
                       	exit 2
                fi
        fi
	cp $updata_path/$files $webapp_path
	$tomcat_run/startup.sh
        sleep 5
        echo "显示tomcat的pid"
        echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
        echo "tomcat startup"
        echo "请手动查看tomcat日志。脚本将会自动退出"
fi
[root@java-server ~]# vim app-jenkins.sh
脚本内容在后面
[root@java-server ~]# chmod +x app-jenkins.sh  #添加执行权限
[root@java-server ~]# mv app-jenkins.sh /opt/script/
```

#### 4.开始构建任务
