jenkins简单使用+jenkins主从架构搭建
主机准备

192.168.1.18 git
192.168.1.19 jenkins
git服务器搭建
[root@git ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@git ~]# yum -y install git
[root@git ~]# useradd git

[root@git git]# passwd git
[root@git git]# su - git
[git@git ~]$ ls
[git@git ~]$ mkdir git-data
[git@git ~]$ git --bare init git-data/

web操作clone仓库
[root@git ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@web ~]# yum -y install git
[root@web ~]# mkdir test
[root@web ~]# cd test/
[root@web test]# git clone [email protected]:/home/git/git-data/

测试提交
[root@web git-data]# ls
[root@web git-data]# echo 123456 > index.html
[root@web git-data]# git config --global user.email "[email protected]"
[root@web git-data]# git config --global user.name "Your Name" #实际生产用自己的
[root@web git-data]# git add .
[root@web git-data]# git status

配置免密登录git服务器
[root@web git-data]# cat /etc/ssh/sshd_config |grep autho
AuthorizedKeysFile .ssh/authorized_keys
[root@web ~]# ssh-keygen
[root@web ~]# cat /root/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDQtVs4WQ.... #配置给git服务器后验证
[root@web git-data]# touch ssh
[root@web git-data]# git add .
[root@web git-data]# git commit -m "ssh test"
[master 85fa019] ssh test
1 file changed, 0 insertions(+), 0 deletions(-)

[root@web git-data]# git push
[root@web ~]# ssh [email protected]
[git@git ~]$ mkdir .ssh
[git@git ~]$ chmod 700 .ssh
[git@git ~]$ chmod 600 .ssh/authorized_keys
[git@git ~]$ cat .ssh/authorized_keys
ssh-rsa AAAAB3NzaC1yc2EAAAADAQ此处是web服务器的秘钥
jenkins主机安装jenkins，配置Jdk
jenkins包源https://repo.huaweicloud.com/jenkins/
[root@jenkins ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@jenkins ~]# yum -y install git mailx postfix
[root@jenkins ~]# systemctl enable postfix --now
[root@jenkins ~]# yum -y install jenkins-2.263.2-1.1.noarch.rpm java
###JDK方便实验用yum装，你也可以尝试下面的方式安装
[root@jenkins ~]# tar xf jdk-8u45-linux-x64.tar.gz
[root@jenkins ~]# tail -n3 /etc/profile
JAVA_HOME=/root/jdk1.8.0_45
PATH=$JAVA_HOME/bin/:$PATH
export JAVA_HOME PATH
[root@jenkins ~]# vim /etc/init.d/jenkins
candidates="
...
/root/jdk1.8.0_45/bin/java
...
"
[root@jenkins ~]# systemctl daemon-reload
[root@jenkins ~]# source /etc/profile
[root@jenkins ~]# java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
启动jenkins
[root@jenkins ~]# systemctl start jenkins
[root@jenkins ~]# ps -ef | grep jenkins
root 12504 1 19 18:40 ? 00:00:12 /root/jdk1.8.0_45/bin/java -Dcom.sun.akuma.Daemon=daemonized -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=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20
[root@jenkins ~]# ss -anutlp| grep 8080
tcp LISTEN 0 50 [::]:8080 [::]:* users:(("java",pid=12504,fd=161))
jenkins升级，下载最新的jenkins的jar包替换重启
(最新版本网络问题无法直接安装)。 https://repo.huaweicloud.com/jenkins/war/2.319/
[root@jenkins ~]# rpm -ql jenkins
/usr/lib/jenkins/jenkins.war
[root@jenkins ~]# cp jenkins.war /usr/lib/jenkins/jenkins.war
[root@jenkins ~]# systemctl restart jenkins
浏览器访问 http://192.168.1.19:8080
按默认的的插件安装即可
[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
7876ea63f38e481fa0aa44f11d5f08a9
Jenkins参数化构建可以选择不同的参数 如git 参数（git tag v1） 字符参数 （git reflog ），文本参数
配置Java-jdk
[root@jenkins ~]# tar xf apache-maven-3.5.0-bin.tar.gz
[root@jenkins ~]# tar xf jdk-8u45-linux-x64.tar.gz
[root@jenkins ~]# ls
apache-maven-3.5.0 apache-maven-3.5.0-bin.tar.gz
jdk1.8.0_45 jdk-8u45-linux-x64.tar.gz
[root@jenkins ~]# mv apache-maven-3.5.0 /usr/local/maven3.3
[root@jenkins ~]# mv jdk1.8.0_45/ /usr/local/jdk1.8
参数化构建
实现变量的调用 ${barnch1}，默认master。如在git
你也可以临时修改默认值，实先参数的改变，也可以设置多个参数，调用变量。
比如想要拉取不同分支的代码，源码管理处配置git的构建分支
Extended Choice Parameter插件
也可以选项配置在jenkins主机上，实现相同的效果
[root@jenkins ~]# cat /usr/local/ceshi.txt
ceshi=first,second,third
Git Parameter插件
给jenkins配置git仓库
[root@jenkins ~]# vim +29 /etc/sysconfig/jenkins
29 JENKINS_USER="root"
[root@jenkins ~]# systemctl restart jenkins
[root@jenkins ~]# ssh-keygen
[root@jenkins ~]# cat .ssh/id_rsa.pub
[root@jenkins ~]# ssh [email protected]
[root@git ~]# su - git
Last login: Sun Jan 16 17:43:49 EST 2022 from 192.168.1.17 on pts/1
[git@git ~]$ vim .ssh/authorized_keys
验证
在web上创建分支并提交
[root@web git-data]# git branch develop
[root@web git-data]# git checkout develop
[root@web git-data]# touch develop.txt
[root@web git-data]# git add .
[root@web git-data]# git commit -m "touch develop"
[root@web git-data]# git push origin develop
重新构建
Jenkins的master与slave
slave主机必须有Java环境，装git且jenkins服务器能够无密码SSH节点，然后重启代理（你也可以重新配置账户密码）
继续添加节点
重新配置项目
配置项目运行的节点选择
此时再次构建查看输出，已经在slave-1.15上构建了
重新配置构建
重现添加两个构建项目test2 test3
