Jenkins打包部署SpringBoot应用

一般而言,一个项目部署的由:拉取代码->构建->测试->打包->部署等过程组成,如果我们经常需要部署项目,特别是在微服务时代,服务特别多的情况下,不停的测试打包部署,那估计得有个人一整天专门做这事了,而这事又是繁琐的重复无意义的,所以就需要一套能够持续集成、持续交付、持续部署的自动化构建流程。

Jenkins是开源CI&CD软件领导者,提供超过1000个插件来支持构建、部署、自动化,满足任何项目的需要。我们可以用Jenkins来构建和部署我们的项目,比如说从我们的代码仓库获取代码,然后将我们的代码打包成可执行的文件,之后通过远程的ssh工具执行脚本来运行我们的项目

一、准备工作

真正的生产环境上,可能是有多台服务器,但是我是用来练手,手头没有多余的服务器,只有一台。所以我就将 Jenkins 和我的 Spring Boot 项目都部署到一台服务器上。

由于本次是使用Docker安装Jenkins,所以需要服务器上提前安装好JDK,Maven,Doker三个必备的环境配置。这里就不过多赘述这三个环境的安装了,可以自行查询资料安装

1、检查 JDK 环境

java -version

[root@liulihui home]# java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
[root@liulihui home]# 

2、检查 Maven 环境

[root@liulihui home]# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/maven/apache-maven-3.6.3
Java version: 1.8.0_231, vendor: Oracle Corporation, runtime: /usr/local/java/jdk/jdk1.8.0_231/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-1160.80.1.el7.x86_64", arch: "amd64", family: "unix"
[root@liulihui home]# 

3、检查 Docker 环境

[root@liulihui home]# docker version
Client: Docker Engine - Community

二、Jenkins的安装及配置

1、Docker 搜索 jenkins 镜像

[root@liulihui home]# docker search jenkins

2、Docker 下载jenkins 镜像

[root@liulihui home]# docker pull jenkins/jenkins:lts

3、Docker容器中运行Jenkins

# 命令如下:
docker run -p 9080:8080 --name liulihui-jenkins \
-u root \
-v /mydata/jenkins_home:/var/jenkins_home \
-v /usr/local/java/jdk/jdk1.8.0_231:/usr/local/jdk1.8 \
-v /usr/local/maven/apache-maven-3.6.3:/usr/local/apache-maven-3.6.3 \
-v $(which docker):/usr/bin/docker \
-v /var/run/docker.sock:/var/run/docker.sock \
-d jenkins/jenkins:lts
# 参数说明:
-p 9080:8080	端口映射(将容器的8080端口【后面的8080】映射到服务器的9080端口【前面的9080】,云服务器需要开通9080端口供外网访问)
--name	容器名字
-u root	用户名
-v /mydata/jenkins_home:/var/jenkins_home	 将配置文件夹挂在到主机(:前面的是主机目录,后面的是容器目录)
-v /usr/local/java/jdk/jdk1.8.0_231:/usr/local/jdk1.8	是把linux下的jdk和容器内的关联(配置Jenkins时使用,:前面的是主机目录,后面的是容器目录)
-v /usr/local/maven/apache-maven-3.6.3:/usr/local/apache-maven-3.6.3	是把linux下的maven和容器内的关联(配置Jenkins时使用,:前面的是主机目录,后面的是容器目录)
-v $(which docker):/usr/bin/docker	是可以在Jenkins容器里使用我们Linux下的docker
-v /var/run/docker.sock:/var/run/docker.sock	是可以在Jenkins容器里使用我们Linux下的docker
-d jenkins/jenkins:lts	后台启动 Jenkins镜像(最新版)
# 查看docker 正在运行的容器
[root@liulihui home]# docker ps 
CONTAINER ID   IMAGE                 COMMAND                  CREATED          STATUS          PORTS                                                  NAMES
9363f69cc773   jenkins/jenkins:lts   "/sbin/tini -- /usr/…"   19 seconds ago   Up 17 seconds   50000/tcp, 0.0.0.0:9080->8080/tcp, :::9080->8080/tcp   liulihui-jenkins

4、Jenkins的配置

运行成功后访问该地址登录Jenkins,第一次登录需要输入管理员密码:http://你的ip:9080/

使用管理员密码进行登录,可以使用以下命令从容器启动日志中获取管理密码:

# 查看日志,获取管理员密码
[root@liulihui home]# docker logs liulihui-jenkins

输入管理员密码后,就进入安装界面,选择安装插件方式,这里我们直接安装推荐的插件

图片:

安装完成后,创建管理员账号:

进入插件安装界面,联网等待插件安装:

进行实例配置:

点击保存并完成,Jenkins就安装已完成

进入Jenkins,点击系统管理->插件管理,进行一些自定义的插件安装

修改插件的站点,把原站点:https://updates.jenkins.io/update-center.json 改为:https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json 可以更快的下载插件

图片:

确保以下插件被正确安装,未安装的在可选插件中搜索安装即可:
(1)根据角色管理权限的插件:Role-based Authorization Strategy
(2)把 Jenkins 打包好的 jar 上传到应用服务器上:Publish Over SSH

已安装插件Role-based Authorization Strategy

已安装插件Publish Over SSH

安装完成后需要重启一下jenkins,在连接后面加restart就可以重启jenkins了,或者使用命令:docker restart 容器名字
http://ip:9080/restart 或者 docker restart 容器名字(这里是 http://ip:9080/restart )

5、配置JDK和Maven

通过系统管理->全局工具配置来进行全局工具的配置,路径都是jenkins里面的路径;
jdk配置

maven配置

系统管理->系统配置,找到 Publish Over SSH,配置好要连接的应用服务器(在后面的操作中需要使用jenkins远程ssh连接到应用服务器,进行构建后的应用部署运行。用户名密码会导致 jar 包上传失败,要在应用服务器上生成 ssh 密钥对。)

Centos 7 上创建SSH密钥查看:https://www.xz577.com/article/170446.htm

图片:

Jenkins使用ssh就可以执行远程的linux脚本了:

进入系统管理->凭据中,添加Gitee登录账号凭据。接下来配置 Gitee 的凭证,要根据这些凭证,才能从 Gitee 上拉取代码下来

填写完成后选择该凭据,就可以正常连接git仓库了;

所有配置工作都做完了,接下来我们就可以开始构建一个项目了。

三、打包部署SpringBoot应用

1、在Jenkins中创建执行任务

图片:

设置任务名称后,选择构建一个自由风格的软件项目:

2、添加git凭据

添加gitee登录账号凭据。接下来配置 gitee 的凭证,要根据这些凭证,才能从 gitee 上拉取代码下来。(如果前面添加了凭证,这里直接选择就行)

图片:

填写完成后选择该凭据,就可以正常连接git仓库了;

3、添加maven构建

maven 构建

选择我们的maven版本,然后设置maven命令和指定pom文件位置:

增加 构建后操作步骤:

因为前面运行jenkins的时候已经做了目录的映射,所以jenkins打完包后其实是会把包同步到服务映射的目录里的。所以这里不需要上传jar包,直接执行xshell命令,进入jar包的目录,执行jar包即可

shell脚本:

#第一步是进入到服务器中生成好的jar包的目录下
cd /mydata/jenkins_home/workspace/demo/target/
#第二步是根据jar包的名字获取运行的pid,并且将该进程杀死
ps -ef | grep demo-0.0.1-SNAPSHOT.jar   |   grep -v   grep   |   awk '{printf $2}'  |  xargs kill -9
#执行 前加载一下环境变量,否则不会执行java -jar 命令
source /etc/profile
#最后一步就是将这个jar后台启动了,并且将日志输出到warpper.log中。
nohup java -jar demo-0.0.1-SNAPSHOT.jar >demo.log &2>1 &
#睡眠1秒
sleep 1
#输出内容,可不加
echo "启动完成>>>>"

四、立即构建

配置完成后,点击立即构建,可以看到控制台输出成功

图片:

选择项目打包分支:

分支配置:

服务部署成功,测试接口返回成功:
