jenkins安装 Jenkins

简介

​ Jenkins的前身是Huds,是一个可扩展的持续集成引擎。Jenkins是一个[开源软件]项目，是基于[Java]开发的一种[持续集成]的流程化的工具，用于监控持续重复的工作，旨在提供一个开放易用的软件平台，使软件项目可以进行持续集成

Jenkins的特点：

• 开源的java语言开发持续集成工具，支持CI，CD；

• 易于安装部署配置：可通过yum安装,或下载war包以及通过docker容器等快速实现安装部署，可方便web界面配置管理；

• 消息通知及测试报告：集成RSS/E-mail通过RSS发布构建结果或当构建完成时通过e-mail通知，生成JUnit/TestNG测试报告；

• 分布式构建：支持Jenkins能够让多台计算机一起构建/测试；

• 文件识别:Jenkins能够跟踪哪次构建生成哪些jar，哪次构建使用哪个版本的jar等；

• 丰富的插件支持:支持扩展插件，你可以开发适合自己团队使用的工具，如git，svn，maven，docker等。

安装tomcat

部署jenkins首要要有tomcat，tomcat又必须有Java环境，所以先安装java环境和tomcat

[root@localhost ~]# yum -y install java-17-openjdk*  wget vim 

下载tomcat，解压并创建软连接

wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.54/bin/apache-tomcat-9.0.54.tar.gz

[root@localhost ~]# ls /usr/src/soft/
apache-tomcat-9.0.54.tar.gz
[root@localhost ~]# tar xf /usr/src/soft/apache-tomcat-9.0.54.tar.gz -C /usr/local/

[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
apache-tomcat-9.0.54  bin  etc  games  include  lib  lib64  libexec  sbin  share  src
[root@localhost local]# ln -sv apache-tomcat-9.0.54 tomcat
'tomcat' -> 'apache-tomcat-9.0.54'

[root@localhost local]# ls
apache-tomcat-9.0.54  bin  etc  games  include  lib  lib64  libexec  sbin  share  src  tomcat

关闭防火墙和selinux

[root@localhost local]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost local]# setenforce 0

启动tomcat

[root@localhost local]# /usr/local/tomcat/bin/catalina.sh start

下载Jenkins (官网 jenkins.io)

右键复制链接下载

wget http://mirrors.jenkins.io/war-stable/2.303.2/jenkins.war

停掉tomcat

再次查看

[root@localhost soft]# ls /usr/local/tomcat/webapps/
ROOT  docs  examples  host-manager  jenkins(自动解压了)  jenkins.war  manager

查看配置文件

[root@localhost ~]# ls -a 
.  ..  .bash_logout  .bash_profile  .bashrc  .cache  .config  .cshrc  .groovy  .java  .jenkins  .tcshrc  .viminfo  anaconda-ks.cfg

[root@localhost ~]# cd .jenkins/

# nodes(多节点时使用)  
# plugins (插件所在目录)
# jobs(浏览器上面创建的任务都会存放在这里)
# secrets(密码秘钥所在目录)
# logs(存放jenkins相关的日志)     jenkins存放数据不依靠数据库，所以在移植时只需要拷贝整个程序主目录即可。
