自己搭建Jenkins步骤

1、先安装maven、jenkins、jdk

jenkins依赖包全家桶（maven、jdk、jenkins）:

https://download.csdn.net/download/YouShouRenSheng/87791333

Linux 中环境安装Jenkins

1、首先安装JDK 最低版本8.0

命令：yum -y install java-1.8.0-openjdk-devel
验证：java -version

2、安装Jenkins步骤

①添加Jenkins源

1）sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
2）sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

②通过yum命令安装Jenkins

sudo yum -y install jenkins

碰到问题：jenkins-2.222.4-1.1.noarch.rpm FAILED 

解决方法： 参考链接 centos安装jenkins简要过程及出现的问题（一）_追梦-北极星的博客-CSDN博客 

一、centos安装jenkins的rpm安装包分为yum安装和rpm安装已经下载好的jenkins包

jenkins安装包的下载路径：jenkins个版本的rpm安装包，下面主要说明rpm安装的流程：

1)获取rpm安装包的的地址，安装包：jenkins-2.213-1.1.noarch.rpm，如下在centos获取安装包下载命令：

wget https://prodjenkinsreleases.blob.core.windows.net/redhat/jenkins-2.213-1.1.noarch.rpm

2)安装下载好的rpm包

sudo rpm -ivh jenkins-2.213-1.1.noarch.rpm

③配置jenkins的端口，设置为:8085

​

 

nohup /home/h3c/jdk/java/bin/java -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8085 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20 &

 

 ④启动jenkins服务

sudo service jenkins start

3、配置jenkins服务

1) 在浏览器访问jenkins页面

http://localhost:8085/

2)根据页面提示位置/var/lib/jenkins/secrets/initialAdminPassword，获取初始密码

命令：cat /var/lib/jenkins/secrets/initialAdminPassword

2、进行jenkins配置

前端vue项目参考这个：

https://download.csdn.net/download/YouShouRenSheng/87791338

后端springboot项目参考这个：

https://download.csdn.net/download/YouShouRenSheng/87791343

3、其他配置

Jenkins所在主机和远程如果不是一台机器，需要做免密配置。

免密配置操作步骤：

1、修改ssh配置

# 每台linux主机修改配置文件/etc/ssh/sshd_config

$ vi /etc/ssh/sshd_config

#启用这三项配置，即去掉这三项的注释

RSAAuthentication yes

PubkeyAuthentication yes

AuthorizedKeysFile      .ssh/authorized_keys



2、生成公私钥

#在源主机上执行 生成公私钥对

$ ssh-keygen -t rsa -P ''

# 查看生成的公私钥

$ cd /root/.ssh/

$ cp id_rsa.pub authorized_keys

id_rsa: 私钥

id_rsa.pub: 公钥

3、安装到目标主机

$ scp /root/.ssh/id_rsa.pub [email protected]:/root/.ssh/;

$ scp /root/.ssh/authorized_keys [email protected]:/root/.ssh/;



4、测试免密登录

ssh [email protected];

4、构建命令

4.1、后端构建命令参考

md5sum /root/.jenkins/workspace/epidemic_yantai_test/target/epidemic_service-1.0.jar

scp -P 22222 /root/.jenkins/workspace/epidemic_yantai_test/target/epidemic_service-1.0.jar   172.168.1.223:/opt/h3c/apps/report_service/report_service.jar  

ssh -p 22222 [email protected]  "md5sum  /opt/h3c/apps/report_service/report_service.jar "

ssh -p 22222 [email protected]  "sh /opt/h3c/apps/report_service/restart.sh "

4.2、前端构建命令

cd /root/.jenkins/workspace/epidemic_yantai_web_test

#npm config set registry https://registry.npm.taobao.org

#npm install

npm run build #打包

cd web

rm -rf web.zip #删除上次打包生成的压缩文件

zip -r web.zip ./web

md5sum /root/.jenkins/workspace/epidemic_yantai_web_test/web/web.zip

scp -P 22222 /root/.jenkins/workspace/epidemic_yantai_web_test/web/web.zip   172.168.1.223:/opt/h3c/apps/report_web/report_web\@tomcat/webapps/web.zip

ssh -p 22222 [email protected]  "md5sum  /opt/h3c/apps/report_web/report_web\@tomcat/webapps/web.zip "

ssh -p 22222 [email protected]  "mv /opt/h3c/apps/report_web/report_web\@tomcat/webapps/web /opt/h3c/apps/report_web/report_web\@tomcat/webapps/web$(date +%Y%m%d%H%M%S)"

ssh -p 22222 [email protected]  "unzip -o -d /opt/h3c/apps/report_web/report_web\@tomcat/webapps/ /opt/h3c/apps/report_web/report_web\@tomcat/webapps/web.zip"

ssh -p 22222 [email protected]  "rm -rf /opt/h3c/apps/report_web/report_web\@tomcat/webapps/web.zip "
