tomcat项目部署

程序打包的工具：（版本号要跟开发人员用的打包工具版本一致）

maven
ant
gradle

manven
简介：
Maven是一个跨平台的项目管理工具，是Apache组织中的一个颇为成功的开源项目。Maven主要服务基于java的项目构建，项目信息管理和依赖管理。
作用：

1.Maven可以创建项目。
2.Maven可以引入依赖的jar包。

ant
简介:
Ant是一个将软件编译、测试、部署等步骤联系在一起的自动化工具，Ant的主要用途是构建Java应用程序。
Ant提供了许多内置的任务，可以编译、组装、测试和运行Java应用程序。Ant还可以有效地用于构建非Java应用程序，例如C或C++应用程序。
优点：
Ant主要有以下优点：

跨平台。Ant是纯Java语言编写的，所以具有很好的跨平台性。
操作简单。Ant由一个内置任务和可选任务组成，运行时需要一个XML文件(构建文件)。
易维护集成。构建文件是XML格式的文件，结构清晰易于维护，由于跨平台和操作简单，很容易集成到开发环境中。

gradle
简介：
Gradle 就是一个自动化构建项目的工具，用来帮助我们自动构建项目。就像我们在写 Java 项目的时候，如果没有构建工具，我们需要先执行 javac 命令先将 Java 源码编译成 class 文件，然后再执行 jar 命令再把 class 文件打成 jar 包。有了构建工具我们只需要点一个按钮就可以了。

3.通过tomcat发布

Jenkins（一种流程控制的软件，用来发布Java语言写的代码）

系统管理的应用

Jenkins打包和发布（示例）

主机	系统平台	IP
1	centos8/redhat8	192.168.2.131
2	centos8/redhat8	192.168.2.129

在1 主机打完包之后使用 scp 传送到 2

主机1 跑Tomcat 跟Jenkins ，主机2 跑Tomcat。

在主机1 打包完之后再传到主机2 ，然后使用主机 2 的IP加端口访问是否能访问到。

手动配置的方式：

#192.168.2.131——主机1上操作
#首先先用命令行的方式进行打包看是否能打包，再用Jenkins 的方式打包。
//下载 git 命令
[root@localhost ~]# yum -y install git

//使用git 命令拉取下来 , 如果是私有的就需要登录账号跟密码，才能拉取
[root@localhost ~]# git clone https://gitee.com/wukongcrm/72crm-java.git
[root@localhost ~]# ls
72crm-java  anaconda-ks.cfg  
[root@localhost ~]# cd 72crm-java/
[root@localhost 72crm-java]# ls
72crm.bat  Dockerfile  LICENSE.txt  pom.xml    src     ux
72crm.sh   docs        package.xml  README.md  

//打包
[root@localhost 72crm-java]# yum -y install maven
[root@localhost 72crm-java]# mvn clean package -Dmaven.test.skip=true

//打包完成后看到target这个包
[root@localhost 72crm-java]# ls
72crm.bat  Dockerfile  LICENSE.txt  pom.xml    src     ux
72crm.sh   docs        package.xml  README.md  target
[root@localhost 72crm-java]# cd target/
[root@localhost target]# ls
archive-tmp  generated-sources   ly-simple-tomcat-0.0.1-SNAPSHOT  
ly-simple-tomcat-0.0.1-SNAPSHOT.war maven-status
classes      maven-archiver     ROOT.jar

//使用 scp 命令传到 2 主机的 /usr/local/tomcat/webapps 的下面
[root@localhost target]# scp ly-simple-tomcat-0.0.1-SNAPSHOT.war root@192.168.2.129:/usr/local/tomcat/webapps/

[root@localhost ~]# ssh-copy-id root@192.168.2.129

##在 主机2 上查看
[root@localhost webapps]# pwd
/usr/local/tomcat/webapps
[root@localhost webapps]# ls
ly-simple-tomcat-0.0.1-SNAPSHOT  ly-simple-tomcat-0.0.1-SNAPSHOT.war

网页配置的方式：

用主机1的IP访问，使用 Jenkins 操作创建一个项目

#脚本内容
pipeline {
    agent any 
    stages {
        stage("pull code"){
            steps {
                git 'https://gitee.com/wukongcrm/72crm-java.git' 
            }
        }    
        stage("make pkg"){
            steps {
                sh """
                    mvn clean package -Dmaven.test.skip=true
                """
            }
        }  
        stage(publish){
            steps{
                sh """
                    scp target/ly-simple-tomcat-0.0.1-SNAPSHOT.war root@192.168.2.129:/usr/local/tomcat/webapps/
                    ssh root@192.168.2.129 '/usr/local/tomcat/bin/catalina.sh stop && /usr/local/tomcat/bin/catalina.sh start'
                """
            }
        }
    }
}

注意：在执行之前需要设置免密登录
