下面的练习基于jenkins版本： 2.249.1
1. 简介
Jenkins是开源CI&CD软件领导者， 提供超过1000个插件来支持构建、部署、自动化， 满足任何项目的需要。
2.安装
当然如果采用docker安装的话会非常简单。
1. 安装JDK
直接yum安装 openjdk
yum install java-1.8.0-openjdk*
2. 下载jenkins
http://mirrors.jenkins.io/war-stable/latest/jenkins.war
如下：
[root@localhost jenkins]# ls jenkins.war
3. 启动jenkins
[root@localhost jenkins]# java -jar jenkins.war --httpPort=8088
Running from: /opt/jenkins/jenkins.war

4. 浏览器访问 8088端口
然后用上面生成的密码进行登录(如果没有可以到上面提示的文件中查找密码)，登录之后查看信息如下：
选择第二个指定的插件进行安装。之后不选择安装插件。
进入主页面：
5. 安装插件
Jenkins >> Manage Jenkins >> Manage Plugins （插件管理也是在这个选项卡）
这里可以看见已经安装的plugin以及可以安装的plugin。这里我们安装：
Maven项目插件：Maven Integration plugin，这个插件可以让我们创建一个maven构建任务。
ssh传输工具插件：Publish Over SSH 项目打包完成后，使用这个插件，通过ssh的方式传输到远程服务器。
Gitlab插件：允许Jenkins访问gitlab服务器，拉取代码
3. 简单使用
maven + gitlab + maven 实现自动部署。
1. 安装git
yum install git
测试：
[root@localhost ~]# git --version git version 1.8.3.1
2.安装maven
http://mirrors.cnnic.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz tar xf apache-maven-3.3.9-bin.tar.gz
(1)设置环境变量：
vi ~/.bashrc
(2)重新加载
source ~/.bashrc
(3)查看mvn版本：
[root@localhost bin]# mvn -v Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T11:41:47-05:00) Maven home: /opt/mvn/apache-maven-3.3.9 Java version: 1.8.0_262, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.262.b10-0.el7_8.x86_64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-1127.el7.x86_64", arch: "amd64", family: "unix"
最后最好是修改mvn的本地仓库地址和默认的中央仓库。如果可以， 将自己本地仓库的文件上传到服务器仓库。参考文末的补充信息。
3.到jenkins中设置
(1) 设置凭据
(2)配置账号：Jenkins >> Manage Jenkins >> System Configuration >> Configure System 中设置：
4. 创建项目：NewItem选择maven Project
(1)设置git代码以及使用的凭证
(2)设定maven的时候需要设定一些参数
主要如下：JDK参数
git如下：
maven如下：
5.保存之后进行构建
(1) 点击立即构建
(2)点击构建会在左下角显示构建的进度
(3) 查看构建状态
可以看到拉取的代码是最新的代码，带gitlab查看也可以看出来。
(4)查看构建日志如下：(Console Output)

(5) 到项目的工作空间查看：
[root@localhost publisSSmTemplate]# pwd /root/.jenkins/workspace/publisSSmTemplate [root@localhost publisSSmTemplate]# ls target/ classes generated-sources maven-archiver maven-status ssmtemplate-0.0.1-SNAPSHOT.jar ssmtemplate-0.0.1-SNAPSHOT.jar.original test-classes
可以看到打包成功，生成了指定的jar包。
(6) 用jenkins自动打包的jar包启动后查看：
[root@localhost publisSSmTemplate]# cd target/ [root@localhost target]# ls classes generated-sources maven-archiver maven-status ssmtemplate-0.0.1-SNAPSHOT.jar ssmtemplate-0.0.1-SNAPSHOT.jar.original test-classes [root@localhost target]# java -jar ssmtemplate-0.0.1-SNAPSHOT.jar --server.port=9000
浏览器访问：
6. 构建后自动启动打包后的脚本，编写shell脚本启动
(1)在/opt/jar目录下创建脚本，脚本内容如下： 用于执行管理服务
#!/bin/bash
#这里可替换为你自己的执行程序，其他代码无需更改
APP_NAME=ssmtemplate-0.0.1-SNAPSHOT.jar
#使用说明，用来提示输入参数
usage() {
echo "Usage: sh 脚本名.sh [start|stop|restart|status]"
exit 1
}
#检查程序是否在运行
is_exist(){
pid=`ps -ef|grep $APP_NAME|grep -v grep|awk '{print $2}' `
#如果不存在返回1，存在返回0
if [ -z "${pid}" ]; then
return 1
else
return 0
fi
}
#启动方法
start(){
is_exist
if [ $? -eq "0" ]; then
echo "${APP_NAME} is already running. pid=${pid} ."
else
nohup java -jar $APP_NAME --server.port=9000 > log.file 2>&1 &
echo "${APP_NAME} start success"
fi
}
#停止方法
stop(){
is_exist
if [ $? -eq "0" ]; then
kill -9 $pid
echo "kill pid ${pid}"
else
echo "${APP_NAME} is not running"
fi
}
#输出运行状态
status(){
is_exist
if [ $? -eq "0" ]; then
echo "${APP_NAME} is running. Pid is ${pid}"
else
echo "${APP_NAME} is NOT running."
fi
}
#重启

}
#根据输入参数，选择执行对应方法，不输入则执行使用说明

(2)启动测试
[root@localhost jar]# sh ssm.sh start ssmtemplate-0.0.1-SNAPSHOT.jar start success [root@localhost jar]# jps -l 91937 sun.tools.jps.Jps 60695 jenkins.war 91917 ssmtemplate-0.0.1-SNAPSHOT.jar
浏览器访问：
(3)杀掉上面进程
[root@localhost jar]# jps -l 92500 sun.tools.jps.Jps 60695 jenkins.war [root@localhost jar]# ls log.file ssm.sh
(4)jenkins中编写脚本
jenkins->publisSSmTemplate->configure中Post Steps编写脚本：
内容如下：
pwd cp ./target/ssmtemplate*.jar /opt/jar/ cd /opt/jar/ sh ssm.sh restart
截图如下：(添加pwd是为了在日志中查看当前目录，默认的当前目录是在 jenkins安装目录/workspace/工程名称下)
(5) 点击buildnow立即构建后查看构建输出信息，如下：

浏览器访问测试：
访问404. 虽然构建成功，但是服务没启动，查看java进程如下：
[root@localhost jar]# jps -l 60695 jenkins.war 97678 sun.tools.jps.Jps
原因： Jenkins-Post Steps-Exec command 运行脚本，脚本执行结束，显示Success，但是服务未启动。Jenkins build结束后会kill掉衍生进程。
解决办法：可以尝试重置变量BUILD_ID，避免Jenkins kill进程。
shell脚本中添加如下命令：
#!/bin/sh export BUILD_ID=anyWordIsOk
重新构建成功后访问：
至此完成了简单的构建。可以实现自动打包以及执行shell脚本启动服务。
7. 构建完成后上传到另一台服务器并执行远程的脚本
这个依赖于Publish Over SSH插件，所以先安装上这个插件。
(0) 准备另一台服务器，用于发布服务，也就是接收jenkins打包后的文件：（ip是130）
[root@localhost ssm]# pwd /opt/jar/ssm [root@localhost ssm]# ls ssm.sh
ssm.sh内容和上面的一样，用于启动服务，如下：
#!/bin/bash
export BUILD_ID=anyWordIsOk
#这里可替换为你自己的执行程序，其他代码无需更改
APP_NAME=ssmtemplate-0.0.1-SNAPSHOT.jar
#使用说明，用来提示输入参数
usage() {
echo "Usage: sh 脚本名.sh [start|stop|restart|status]"
exit 1
}
#检查程序是否在运行

#如果不存在返回1，存在返回0

(1) 配置SSHserver：Jenkins -》Configure System -》 SSH Servers 点击add可以添加多个
点击后可以测试连接。
(2)Jenkins -》 项目名称 -》 configure 中在 Post Steps中设置上传到其他服务器： Post Steps 可以添加多个操作。
参数解释：
Source files: 是上传的文件，可以用通配符的形式
remove prefix：删除的目录，如果不填，会在目录下创建一个target目录。官方解释如下:
if Source files were target/deployment/images/**/ then you may want Remove prefix to be target/deployment This would create the images folder under the remote directory, and not target/deployment Jenkins environment variables can be used in this path.
Remote directory：是上传的位置，是一个相对路径。相对于上面SSHserver设置的路径。比如我上面设置的是/opt/jar，并且这个属性设置为/ssm。则文件上传后位于/opt/jar/ssm/ 目录
Exec command： 是上传后执行的远程命令。在上面我也是启动服务，注意默认路径是当前登录用户的根目录。我是root用户，所以默认在/root
(3) 重新构建并且查看日志：可以看到构建成功，并且在jenkins所在服务器和远程130服务器都启动了服务。浏览器也可以访问到。

4.gitlab自动构建
常用的应该有定时构建，cron表达式触发。token以url方式构建以及webhok自动构建。
1. 通过生成token以url的方式构建
(1) 到jenkins首页创建一个用户
创建了一个 test/111222的用户。
(2) 给用户赋权：Manage Jenkins->Configure Global Security
(3)yongtest/111222之后登录，点击登录的用户之后点击configure -》 add API Token
名称为：ssmtoken
token串为：11f95b0b68a4f6a4cbb283226a249de4df
(3) 项目设置构建选择：Trigger builds remotely (e.g., from scripts)，例如： api名称是随便写的
(4)远程访问，开始构建：
访问如下url即可：
http://test:11f95b0b68a4f6a4cbb283226a249de4df@192.168.1.129:8088/job/publisSSmTemplate/build?token=pubssmtoken
规则为： http://用户名:token串@主机/job/项目名称/build?token=token名称 需要注意这里的token名称是在项目名称填写的名称，如果写错不允许构建。
(5)查看构建日志
Started by remote host 192.168.1.130 Running as SYSTEM Building in workspace /root/.jenkins/workspace/publisSSmTemplate The recommended git tool is: NONE ...
补充：这种方式需要每次都手动复制URL访问，可以用gitlab的webhook在代码提交后自动访问URL：
settings -> Integrations Settings 增加webhook的url，如下：
2.以webhook自动构建
依赖Generic Webhook Trigger插件，先到jenkins插件管理安装该插件。
首先我们需要先了解，gitlab在发动webhook请求的时候会携带一些请求参数以及请求头，而且不同的事件有不同的参数和头。然后我们需要在jenkins中根据不同的请求参数来判断是否进行构建。
比如push events推送代码事件发送的数据如下：
Request header:
X-Gitlab-Event: Push Hook
Request body:
{

}
(1)到项目中配置Build Triggers 选择： Generic Webhook Trigger，进行参数设置
Post content parameters添加两个变量：从请求参数提取ref和project.name赋值到tempref和projectname变量中
下面两个打上对勾，便于查看日志：
Optional filter配置验证：验证上面提取的变量组合起来(Text中)是否满足Expression表达式(这里验证是ssmTemplate项目的master分支)。如果满足会进行下面的构建操作，不满足不会进行构建
(2)验证：在另一台服务器上访问：
直接访问webhookurl发现没权限：
[root@localhost ssm]# curl http://192.168.1.129:8088//generic-webhook-trigger/invoke
{"jobs":null,"message":"Did not find any jobs with GenericTrigger configured! If you are using a token, you need to pass it like ...trigger/invoke?token=TOKENHERE. If you are not using a token, you need to authenticate like http://user:passsword@jenkins/generic-webhook... "}
可以加用户名密码进行访问，如下： 说明已经访问到webhook的url，只是参数不匹配
[root@localhost ssm]# curl http://test:111222@192.168.1.129:8088//generic-webhook-trigger/invoke
{"jobs":{"publisSSmTemplate":{"regexpFilterExpression":"^(ssmTemplate-refs/heads/master)$","triggered":false,"resolvedVariables":{"projectname":"","tempref":""},"regexpFilterText":"-","id":0,"url":""}},"message":"Triggered jobs."}
(3)到gitlab配置webhook为上面地址：
(4)向master分支提交代码查看构建记录：可以看到是通过webhook产生的构建，并且打印了post content和variables
(5)测试向其他分支提交代码发现不会触发构建。
基于webhook的自动构建也完成。
补充：构建方式还有基于cron表达式周期性执行以及基于其他项目构建完成之后开始构建等方法，如下：
补充： jenkins的版本是2.249.1
这个可以到 jenkins的安装目录下config.xml中查看。
补充： jenkins配置账户
Manage Jenkins -》 Manager Users 进行设置,可以创建用户。
补充：jenkins的工作空间默认在安装目录下的workspace目录
比如我新建了一个任务是 publisSSmTemplate， 在jenkins目录下会有一个对应的目录，拉下来的代码会放在该目录，比如：
[root@localhost publisSSmTemplate]# pwd /root/.jenkins/workspace/publisSSmTemplate
补充：mvn仓库的默认位置是 ${user.home}/.m2/repository 目录，中央仓库默认是http://repo1.maven.org/maven2/，可以通过修改 mvn/conf/settings.xml 中修改。
(1)查看默认仓库：
[root@localhost conf]# head -n 50 settings.xml

(2) 修改默认仓库以及默认中央仓库
<localRepository>/opt/mvn/repository</localRepository>
仓库：
<mirrors>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
(3) 可以将自己本地仓库的文件上传到服务器,可以减少第一次打包下载依赖的时间。
