jenkins部署tomcat

maven编译环境（jenkins服务器）
运行环境（web服务器）

一、部署maven编译环境（jenkins）

Maven是一个Java项目管理和构建工具，它可以定义项目结构、项目依赖，并使用统一的方式进行自动化构建，是Java项目不可缺少的工具。

1.jenkins部署maven软件
1.1下载安装包

cd /opt
wget https://mirrors.aliyun.com/apache/maven/maven-3/3.9.9/binaries/apache-maven-3.9.9-bin.tar.gz

1.2解压

tar -xf  apache-maven-3.9.9-bin.tar.gz -C /usr/local/

1.3配置环境变量

[root@master01 opt]# vim /etc/profile.d/maven.sh
[root@master01 opt]# cat /etc/profile.d/maven.sh 
export MAVEN_HOME=/usr/local/apache-maven-3.9.9
export PATH=$MAVEN_HOME/bin:$PATH
[root@master01 opt]# source /etc/profile
[root@master01 opt]# #刷新

1.4安装JDK

#jenkins安装的时候部署过
[root@master01 opt]# mvn --version
Apache Maven 3.9.9 (8e8579a9e76f7d015ee5ec7bfcdc97d260186937)
Maven home: /usr/local/apache-maven-3.9.9
Java version: 17.0.0.1, vendor: Oracle Corporation, runtime: /opt/jdk-17.0.0.1
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-1160.el7.x86_64", arch: "amd64", family: "unix"

2.配置jenkins+maven
2.1配置JDK

2.2配置maven环境变量

2.3安装maven插件

3.创建代码仓库

4.模拟代码上传
4.1拉取新仓库

[root@master01 opt]# cd /root
[root@master01 ~]# git clone git@192.168.3.100:root/tomcat.git
正克隆到 'tomcat'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0 (from 0)
接收对象中: 100% (3/3), done.
[root@master01 ~]# cd /tmp/
[root@master01 tmp]# cd /root/tomcat/
[root@master01 tomcat]# ls
README.md

4.2配置个人信息

[root@master01 tomcat]# git config --global user.email "123@qq.com"
[root@master01 tomcat]# git config --global user.name "axingkf"

4.3模拟代码上传

vi javatest.java
public class JavaVersion {
    public static void main(String[] args) {
        // 打印当前 Java 版本信息
        System.out.println("Java Version: " + System.getProperty("java.version"));
        System.out.println("Java Vendor: " + System.getProperty("java.vendor"));
        System.out.println("Java Vendor URL: " + System.getProperty("java.vendor.url"));
        System.out.println("Java Home: " + System.getProperty("java.home"));
    }
}

#添加所有文件到暂存区
[root@master01 tomcat]# git add .
#提交暂存区的制定文件到仓库区
[root@master01 tomcat]# git commit -m "第一次java开发"
[main 51687a7] 第一次java开发
 1 file changed, 9 insertions(+)
 create mode 100644 javatest.java
 #没有master这个分区
[root@master01 tomcat]# git push -u origin master
error: src refspec master does not match any.
error: 无法推送一些引用到 'git@192.168.3.100:root/tomcat.git'
# 上传到远程
[root@master01 tomcat]# git push -u origin main
Counting objects: 4, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (3/3), done.

   c086be9..51687a7  main -> main
分支 main 设置为跟踪来自 origin 的远程分支 main。
[root@master01 tomcat]#

5、创建maven仓库

mkdir -pv /data/software/repository
chown jenkins.jenkins /data/software/repository/

vim /usr/local/apache-maven-3.6.3/conf/settings.xml
#添加本地仓库路径和阿里云镜像
<?xml version="1.0" encoding="UTF-8"?>

 | This is the configuration file for Maven. It can be specified at two levels:
 |
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in ${user.home}/.m2/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.conf}/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -gs /path/to/global/settings.xml
 |
 | The sections in this sample file are intended to give you a running start at
 | getting the most out of your Maven installation. Where appropriate, the default
 | values (values used when the setting is not specified) are provided.

  <!-- profiles -->
  <!-- This is a list of profiles which can be activated in a variety of ways, and which can modify
       the build process. Profiles provided in the settings.xml are intended to provide local machine-
       specific paths and repository locations which allow the build to work in the local environment.
   -->
  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.

6、测试maven

测试

二、部署运行环境
1、安装tomcat

略

2、配置方便启动

Description=Tomcat 9
After=network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment=JAVA_HOME=/usr/local/java/jdk-17.0.0.1
Environment=CATALINA_PID=/opt/apache-tomcat-9.0.98/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/apache-tomcat-9.0.98
Environment=CATALINA_BASE=/opt/apache-tomcat-9.0.98
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M'
