tomcat部署jenkins项目的实现示例

作者：运维工程师001号

Jenkins自动化部署可以解决集成、测试、部署等重复性的工作，本文主要介绍了tomcat部署jenkins项目，具有一定的参考价值，感兴趣的可以了解一下

jenkins简介

​ Jenkins自动化部署可以解决集成、测试、部署等重复性的工作，工具集成的效率明显高于人工操作；并且持续集成可以更早的获取代码变更的信息，从而更早的进入测试阶段，更早的发现问题，这样解决问题的成本就会显著下降：持续集成缩短了从开发、集成、测试、部署各个环节的时间，从而也就缩短了中间出现的等待时间；持续集成也意味着开发、集成、测试、部署得以持续。

Jenkins的主要特点和功能：

环境准备：

部署jenkins前先部署tomcat，tomcat部署方法请参考：tomcat

jenkins部署

下载jenkins软件包

下载地址：Jenkins download and deployment

[root@localhost ~]# wget https://get.jenkins.io/war-stable/2.414.2/jenkins.war
...
Length: 89532729 (85M) [application/java-archive]

[root@localhost ~]# 
[root@localhost ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.65.tar.gz  jenkins.war
[root@localhost ~]#

将jenkins.war文件拷贝至webapps目录下

[root@localhost ~]# cd /usr/local/tomcat/webapps/
[root@localhost webapps]# 
[root@localhost webapps]# ls
docs  examples  host-manager  manager  ROOT
[root@localhost webapps]# 
[root@localhost webapps]# cp /root/jenkins.war .
[root@localhost webapps]# ls
docs  examples  host-manager  jenkins.war  manager  ROOT
[root@localhost webapps]#

编辑server.xml配置文件

开启AJP协议，用于tomcat跟apache的效率，注意如果有多个tomcat,则改一下端口号，比如8009变8010

[root@localhost ~]# cd /usr/local/tomcat/conf/
[root@localhost conf]# ls
Catalina         catalina.properties  jaspic-providers.xml  logging.properties  tomcat-users.xml  web.xml
catalina.policy  context.xml          jaspic-providers.xsd  server.xml          tomcat-users.xsd
[root@localhost conf]# 
[root@localhost conf]# vim server.xml 
...
    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector protocol="AJP/1.3"
               address="::1"
               port="8009"
               redirectPort="8443" />
...
"server.xml" 168L, 7563C written                                                                          
[root@localhost conf]#

重启服务，jenkins.war包会自动解压缩

                git 'https://gitee.com/forgotten/tomcat-java-demo'
                sh 'mvn clean package -Dmaven.test.skip=true'
            }
        }
        stage("deploy"){
            steps {
                sh 'cp /root/tomcat-java-demo/target/ly-simple-tomcat-0.0.1-SNAPSHOT.war /usr/local/tomcat/webapps'
                sh '/usr/local/tomcat/bin/catalina.sh stop && /usr/local/tomcat/bin/catalina.sh start'
            }
        }
    }
}

构建成功

流水线构建完成后webapps目录下可以看到拷贝和解压的ly-simple-tomcat-0.0.1-SNAPSHOT.war文件，服务重启后会自动解压war类型的文件

[root@localhost ~]# cd /usr/local/tomcat/webapps/
[root@localhost webapps]# 
[root@localhost webapps]# ls
docs      host-manager  jenkins.war                      ly-simple-tomcat-0.0.1-SNAPSHOT.war  ROOT
examples  jenkins       ly-simple-tomcat-0.0.1-SNAPSHOT  manager                              test
[root@localhost webapps]#

访问网页，在地址栏端口号后面加上 /ly-simple-tomcat-0.0.1-SNAPSHOT/
