jenkins 自动化部署
1、安装JDK
1.1、上传linux的JDK安装包到opt目录下，并解压
1.2、配置jdk环境变量vim /etc/profile 在尾部添加如下内容，添加完成后执行命令：source /etc/profile
# jdk环境变量
export JAVA_HOME=/opt/jdk1.8.0_102
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar1.3、依次输入java、javac、java -version，检查安装是否成功
2、linux安装maven
2.1、上传apache-maven-3.6.0-bin.tar.gz安装包到linux服务器opt目录下，并且解压
2.2、进入apache-maven-3.6.0/conf/目录下，修改settings.xml文件
2.3、配置maven环境变量vim /etc/profile 在尾部添加如下内容，添加完成后执行命令：source /etc/profile
# maven 环境变量
export MAVEN_HOME=/opt/apache-maven-3.6.0
export MAVEN_HOME
export PATH=$PATH:$MAVEN_HOME/bin2.3、输入 mvn -version校验是否成功
3、安装Jenkins到linux服务器
3.1、下载Jenkins的安装包jenkins.war
3.2、上传Jenkins安装包到tomcat目录下，修改tomcat端口号并启动tomcat
3.3、打开浏览器访问ip:port/jenkins进行Jenkins安装
3.4、复制浏览器出现的路径，使用vim命令打开此文件获取安装秘钥，点击下一步，直接点击第一个自动安装，安装完成后输入管理员账号密码姓名以及邮箱信息
3.5、点击左边系统管理->插件管理->点击第二个页签可选插件->右上角过滤输入Loca->勾选Locale plugin和Localization: Chinese (Simplified)插件，选择下方第一个按钮直接安装，等待安装完成
3.6、点击系统管理->系统设置->Locale栏-> Default Language输入：zh_CN 勾选下方的Ignore browser preference and force this language to all users,确认无误后点击保存，至此Jenkins语言包安装成功
3.7、点击系统管理->插件管理->可选插件，搜索maven->安装Maven Integration插件
4、配置Jenkins的maven项目
4.1、全局工具配置--点击系统管理-全局工具配置
4.1.1、maven配置-默认 settings 提供和默认全局 settings 提供的下拉框都选择为文件系统中的setting文件-在下方输入maven的配置文件路径，例：/opt/apache-maven-3.6.0/conf/settings.xml
4.1.2、jdk-点击jdk安装-去掉自动安装的勾选-别名输入jdk1.8-java_home输入jdk的根目录
4.1.3、maven-点击安装maven-去掉自动安装的勾选-name输入maven，maven_home输入/opt/apache-maven-3.6.0
4.1.4、以上三项确认无误，点击save保存
4.2、点击新建任务-输入项目名称-选择构建一个maven项目-点击确定
4.3、在源码管理选择使用git还是SVN，我们使用svn则选择subversion，Repository URL选项输入源码的根目录，Credentials选择后面的钥匙按钮添加凭证，在天出矿输入个人svn的账号密码保存，然后在Credentials后面下拉列表选择刚才配置的账号密码
4.3、下拉到Post Steps选项，选择Run only if build succeeds（构建完成之后），然后点击下拉列表选择执行shell，把下面附的shell脚本里面的内容复制到输入框中，修改shell脚本中：TOMCAT_APP_PATH变量的值为个人需要最终部署项目app的tomcat绝对路径（个人建议不要和Jenkins放在同一个tomcat中），APP_NAME变量的值更改为软件app的名称（也就是最终war包的名称除了后面的后缀，.war），修改完确认无误，然后点击保存
4.4、点击最左上角的Jenkins返回首页，然后选择刚才新建的项目点击项目名称进入工作空间，点击左边立即构建，在下方Build History表格中可以看到构建版本，点击当前正在构建的版本，点击左方控制台输出，查看构建详细日志，等待构建完成
4.5、等待构建完成后，输入部署的项目的访问地址进行访问验证是否部署成功

| 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.

<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->
<localRepository>/opt/apache-maven-3.6.0/repository</localRepository>
<!-- interactiveMode
| This will determine whether maven prompts you when it needs input. If set to false,
| maven will use a sensible default value, perhaps based on some other setting, for
| the parameter in question.
|
| Default: true
<interactiveMode>true</interactiveMode>
-->
<!-- offline
| Determines whether maven should attempt to connect to the network when executing a build.
| This will have an effect on artifact downloads, artifact deployment, and others.
|
| Default: false
<offline>false</offline>
-->
<!-- pluginGroups
| This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
| when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
| "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.

<!-- servers
| This is a list of authentication profiles, keyed by the server-id used within the system.
| Authentication profiles can be used whenever maven must make a connection to a remote server.
|-->
<servers>
<!-- server
| Specifies the authentication information to use when connecting to a particular server, identified by
| a unique name within the system (referred to by the ‘id‘ attribute below).
|
| NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
| used together.
|

<!-- 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>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>

<!-- 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.
|
|-->
<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.
|
| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
<profile>
<id>jdk-1.4</id>
<activation>
<jdk>1.4</jdk>
</activation>
<repositories>
<repository>
<id>jdk14</id>
<name>Repository for JDK 1.4 builds</name>
<url>http://www.myhost.com/maven/jdk14</url>
<layout>default</layout>

<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
<!--
| Here is another profile, activated by the system property ‘target-env‘ with a value of ‘dev‘,
| which provides a specific path to the Tomcat instance. To use this, your plugin configuration
| might hypothetically look like:
|
| ...
| <plugin>
| <groupId>org.myco.myplugins</groupId>
| <artifactId>myplugin</artifactId>
|
| <configuration>
| <tomcatLocation>${tomcatPath}</tomcatLocation>
| </configuration>
| </plugin>
| ...
|
| NOTE: If you just wanted to inject this configuration whenever someone set ‘target-env‘ to
| anything, you could just leave off the <value/> inside the activation-property.
|

<id>env-dev</id>
