一、安装环境
1. 机器要求：
256 MB 内存，建议大于 512 MB
10 GB 的硬盘空间（用于 Jenkins 和 Docker 镜像）
需要安装以下软件：
Java 8 ( JRE 或者 JDK 都可以)
2. 安装JDK
检索可用包
yum search java|grep jdk安装JRE
yum install java-1.8.0-openjdk安装JDK
yum install -y java-devel3.将 jenkins.war 放到服务器中
jenkins.war下载地址（注意版本，我这里用的是）：Jenkins 的安装和设置
执行命令：
java -jar jenkins.war首次启动war包会在`/root/.jenkins`生成配置文件，待完全启动成功后 访问服务器8080端口完成配置，在控制台会又初始化后的密码：
2022-12-25 11:52:50.697+0000 [id=41] INFO hudson.model.AsyncPeriodicWork#lambda$doRun$1: Started Download metadata
2022-12-25 11:52:50.758+0000 [id=41] INFO hudson.util.Retrier#start: Attempt #1 to do the action check updates server
2022-12-25 11:52:51.166+0000 [id=26] INFO jenkins.install.SetupWizard#init:
*************************************************************
*************************************************************
*************************************************************
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
91fb7749cf4f4320b927b36dc2c45d37
This may also be found at: /root/.jenkins/secrets/initialAdminPassword
*************************************************************
*************************************************************
*************************************************************
不要忘了关闭防火墙哦！，浏览器访问：http://192.168.1.129:8080/
输入初始化密码：91fb7749cf4f4320b927b36dc2c45d37
选择安装推荐的插件
安装完成后，创建管理员
注意：这里启动完jenkins后，建议配置一下免安全认证，不然重启后，登陆报错：
jenkins:RI: /j_spring_security_check具体配置如下：
vi /root/.jenkins/config.xml将 <useSecurity>true</useSecurity> 改为 <useSecurity>false</useSecurity> 然后重启！
4. 安装maven
将mavne包放到服务器中
解压
tar -vxzf apache-maven-3.8.6-bin.tar.gz移动并改名
mv apache-maven-3.8.6 /usr/local/maven5. Jenkins安装插件
登陆Jenkins后，选择 Manage Jenkins
选择 Manage Plugins
安装构建项目用的 maven集成插件
最下面等待安装
安装完成后，返回首页，点击新建Item
创建一个maven项目
将GitLab项目地址添加上，这里也需要在Jenkins服务器中安装git
注意：Credentials 为添加凭证，这里作为公开测试使用，没有添加
安装git命令
yum install git这里可以指定分支
6. 配置maven和pom.xml
在 Global Tool Configuration中配置 maven路径，即为服务器安装的路径：/usr/local/maven
在之前的项目配置中，配置 pom.xml文件位置：即 项目名称+pom.xml
7. 修改阿里云镜像

| This is the configuration file for Maven. It can be specified at two levels:

|
| 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

| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->

<!-- interactiveMode

<!-- pluginGroups
| This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.

| "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.

<!-- mirrors
| This is a list of mirrors to be used in downloading artifacts from remote repositories.
|
| It works like this: a POM may declare a repository to use in resolving certain artifacts.
| However, this repository may have problems with heavy traffic at times, so people have mirrored
| it to several places.
|
| That repository definition will have a unique id, so we can create a mirror reference for that
| repository, to be used as an alternate download site. The mirror site will be the preferred
| server for that repository.
|-->
<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>

<!-- 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.
|
| For example, if you have an integration testing plugin - like cactus - that needs to know where
| your Tomcat instance is installed, you can provide a variable here such that the variable is
| dereferenced during the build process to configure the cactus plugin.
|
| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
| section of this document (settings.xml) - will be discussed later. Another way essentially
| relies on the detection of a system property, either matching a particular value for the property,
| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
| value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
| Finally, the list of active profiles can be specified directly from the command line.
|
| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
| repositories, plugin repositories, and free-form properties to be used as configuration
| variables for plugins in the POM.

</settings>8、构建项目包
等待构建完成中可以查看控制台输出
构建完成
9. 查看构建好的jar包
/root/.m2/repository/com/fan/RabbitmqTest/0.0.1-SNAPSHOT
10. 安装 Publish Over SSH 插件
11. 添加远程服务器
安装成功后，在系统配置中添加一台远程服务器
配置远程服务器信息
测试为Success 即可
12. 配置构建后自启动
点击项目名称，找到配置
在 Post Steps 中找到刚刚安装的插件
这里需要注意的是，匹配传递的 jar 包 ，**/ 表示任意目录，实际生成的 jar包名称为：RabbitmqTest-0.0.1-SNAPSHOT.jar，所以，这里也需要匹配
重新构建后，自动启动。
这里传递成功后执行的命令可能会因为nohup日志导致卡死，从而超时，所以对命令进行优化：
nohup java -jar /root/hzf/RabbitmqTest*.jar &>mylog.log &未完待续...
