# 下载安装JDK

下载地址：jdk-11.0.20_linux-x64_bin.tar.gz (opens new window)

解压

tar -zxvf jdk-11.0.20_linux-x64_bin.tar.gz

移动到/opt目录下

mv jdk-11.0.20 /opt/

配置环境变量

vim /etc/profile

export JAVA_HOME=/opt/jdk-11.0.20
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar

加载环境变量

source /etc/profile

验证是否配置成功

# java -version
java version "11.0.20" 2023-07-18 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.20+9-LTS-256)

# 安装Jenkins

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate
1
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
1
yum install -y jenkins

如果 install 时报错，提示

warning: /var/cache/yum/x86_64/7/jenkins/packages/jenkins-2.414.2-1.1.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID ef5975ca: NOKEY

# 配置Jenkins使用端口

默认：8080，修改配置文件vim /etc/sysconfig/jenkins

JENKINS_PORT="8080"
1

# 修改Jendins存储路径

修改vim /etc/sysconfig/jenkins

JENKINS_HOME=/var/lib/jendins
1

更改路径后，要手动创建这个目录

# 配置权限

配置权限，修改为root，修改文件vim /etc/sysconfig/jenkins

JENKINS_USER="root"
1

修改目录权限

chown -R root:root /var/lib/jenkins
 
chown -R root:root /var/cache/jenkins
 
chown -R root:root /var/log/jenkins

cd /etc/init.d
#重启jenkins
./jenkins restart
#启动jenkins
./jenkins start
#查看jenkins状态

输入管理员密码，查看密码

cat /var/lib/jenkins/secrets/initialAdminPassword

我的服务器访问不到Jenkins插件地址（这里看网络环境），这里我配置了代理

image-20230921161919356

选择安装推荐的插件

image-20230921161952356

到下面这个页面后，就等待安装

image-20230921162016827

安装完成后进入创建管理员用户页面

image-20230921163402146

配置URL，默认的即可

# 添加服务器节点

  • 服务器节点需要安装JDK11
  • 配置之前在Jenkins服务器通过ssh连接一下从节点,输入yes即可，不然无法安装成功从节点
# ssh 172.16.84.19
The authenticity of host '172.16.84.19 (172.16.84.19)' can't be established.
ECDSA key fingerprint is SHA256:/VZpxzlzpZqNTgoUR+XWXsnypMdq6n/q+/kWbirNxMo.

点击New Node

image-20230921171943104

添加新节点

image-20230921172009150

填写配置

image-20230921172312291

image-20230921172335178

点击添加凭证后，填写服务器账号密码

image-20230921172511357

填写描述后面好分我们配置的账号密码

image-20230921172714153

点击添加

image-20230921172522416

选择我们刚刚设置的凭证

image-20230921172756805

配置Jenkins使用的jdk路径

image-20230921174811409

完整配置如下

image-20230921174858330

点击保存

可以在节点中看到添加成功

image-20230921174921149

如果失败可以在日志页面查看具体原因

# 安装SSH插件

进入 Dashboard -> Manage Jenkins -> Plugins 页面

image-20230921171533375

安装下面插件：

image-20230922094334426

image-20230922142005693

安装完成

image-20230922101853740

安装完成后重启Jenkins

# 部署Maven项目

# 配置GIT权限

注意：如果Jenkins节点多，每个节点都需要执行这个步骤

配置Git权限，这里我使用的都是GitLab举例

在Jenkins服务所在服务器生成公钥

ssh-keygen -t ecdsa
1

在GitLab添加生成的公钥

cat ~/.ssh/id_ecdsa.pub 
ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHANTYAAAAIbmlzdHAyNTYAAABBBFY0VjZSDr/QyBjIf2OUC9N1QyuGFTcTGbS7fq4ECW1FUNQSHSJ0X/gLQmANT3S6hZLmZB0VhpG2gn8FckWoC9Y= root@centos7.9-template
1
2

image-20230922105526435

添加完成之后，在服务器Shell执行一次命令，会提示让你输入YES，仅首次配置服务器需要执行该步骤

$ git clone git@192.168.1.1:jast/cp.git

ECDSA key fingerprint is SHA256:/VZpxzlzpZqNTgoUR+XWXsnypMdq6n/q+/kWbirNxMo.
ECDSA key fingerprint is MD5:86:f4:2c:0c:df:47:e5:1e:ed:c7:00:87:3e:ee:fb:47.
Are you sure you want to continue connecting (yes/no)? yes

# 创建Jenkins任务

新建任务

image-20230922112048852

image-20230922112221493

设置我们需要再哪个服务器上运行

这里输入的节点，与我们创建节点时设置的名称一样，我们统一用IP地址命名

image-20230922112938682

image-20230922112356966

设置拉取Git代码分支

image-20230922113743767

此处填写的develop就是我们代码的分支，即

image-20230922113826699

创建拉取代码后执行的脚本，Build Steps -> 执行shell

image-20230922113042849

初步验证，随便输入几个命令查看是否能拉取代码成功

image-20230922113235841

查看输出

image-20230922113428647

可以看到我们刚刚填写shell命令的输出

image-20230922113456129

运行程序道理就相同了，可以直接通过shell配置自动化操作，就不一一介绍。
