Jenkins+Maven+Gitlab+Tomcat自动化构建打包+部署

环境准备

导入项目包

配置jenkins

构建项目

配置项目上线

修改项目代码测试

环境准备

本实操项目环境基于https://blog.csdn.net/Lzcsfg/article/details/140359830

首先在node01主机中操作，本次操作需要java8的版本，将之前安装的java17卸载

Java Downloads | Oraclehttps://www.oracle.com/java/technologies/downloads/?er=221886#java8

bash 复制代码

#卸载之前17版本
[root@node01 ~]# yum remove -y java
#下载jdk8
[root@node01 ~]# wget -O jdk-8u411.rpm https://download.oracle.com/otn/java/jdk/8u411-b09/43d62d619be4e416215729597d70b8ac/jdk-8u411-linux-x64.rpm?AuthParam=1720715155_db3de5003585c6f38ce0b8e87c922e4b
[root@node01 ~]# yum install -y jdk-8u411.rpm

[root@node01 ~]# java -version
java version "1.8.0_411"
Java(TM) SE Runtime Environment (build 1.8.0_411-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.411-b09, mixed mode)

Index of apache-local/tomcathttps://mirrors.huaweicloud.com/apache/tomcat/

bash 复制代码

#下载tomcat8
[root@node01 ~]# wget https://mirrors.huaweicloud.com/apache/tomcat/tomcat-8/v8.5.100/bin/apache-tomcat-8.5.100.tar.gz
[root@node01 ~]# tar -zxvf apache-tomcat-8.5.100.tar.gz
[root@node01 ~]# mv apache-tomcat-8.5.100 /usr/local/tomcat

修改tomcat配置

bash 复制代码

[root@node01 ~]# vim /usr/local/tomcat/webapps/docs/META-INF/context.xml

bash 复制代码

[root@node01 ~]# vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml

bash 复制代码

[root@node01 ~]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml

bash 复制代码

[root@node01 ~]# vim /usr/local/tomcat/conf/tomcat-users.xml
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="admin-gui"/>
  <role rolename="admin-script"/>
  <user username="admin" password="123456" roles="tomcat,manager-gui,manager-script,admin-gui,admin-script"/>

记住这个用户名admin 密码123456 这里定义好了登录tomcat管理页面的账户

启动tomcat验证

bash 复制代码

[root@node01 ~]# /usr/local/tomcat/bin/startup.sh

导入项目包

来到gitlab服务主机的web页面，登录后导入项目

Git仓库URL

bash 复制代码

https://gitee.com/hyunze/easy-springmvc-maven

点击导入后等待一会即可完成

将jenkins服务主机的公钥复制，到gitlab平台里

bash 复制代码

[root@jenkins .ssh]# cat /root/.ssh/id_rsa.pub 
ssh-rsa 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 root@jenkins

配置jenkins

来到jenkins主机的web页面，确保下载了这两个插件，没有则下载

Maven Integration plugin

Deploy to container Plugin

来到jenkins主机下载部署jdk8的版本，因为本项目打包需要用到jdk8

bash 复制代码

[root@jenkins ~]# wget -O jdk-8u411.rpm https://download.oracle.com/otn/java/jdk/8u421-b09/d8aa705069af427f9b83e66b34f5e380/jdk-8u421-linux-x64.rpm?AuthParam=1721458472_cbb2875b7eee184c7878c44b44975d71
[root@jenkins ~]# yum install -y jdk-8u411.rpm

安装目录在/usr/lib/jvm/jdk-1.8.0_421-oracle-x64

maven和git也已经预装过了在之前的环境里。

现在来到jenkins的web页面，修改java配置

构建项目

在gitlab页面复制仓库的连接，粘贴进jenkins的配置里。

回到jenkins页面

在jenkins主机工作空间中查看war包

bash 复制代码

[root@jenkins maven-project]# ll /root/.jenkins/workspace/maven-project
total 44
-rw-r----- 1 root root 35181 Jul 12 05:50 LICENSE
-rw-r----- 1 root root    99 Jul 12 05:50 README.md

[root@jenkins maven-project]# ll target/

drwxr-x--- 3 root root      35 Jul 12 06:06 maven-status

这里面就已经有了打好的war包，就成功构建并打包了。
