1、準(zhǔn)備環(huán)境:
兩臺(tái)機(jī)器
git-server ----https://github.com/bingyue/easy-springmvc-maven
jenkins-server ---47.97.90.120---最好是3個(gè)G以上
java-server -----175.24.61.147
1.部署jenkins服務(wù)器
安裝git客戶端:
[root@jenkins-server ~]# systemctl stop firewalld && setenforce 0
[root@jenkins-server ~]# yum install -y git #安裝git客戶端
[root@jenkins-server ~]# ssh-keygen
[root@jenkins-server ~]# ssh-copy-id -i root@175.24.61.147 #拷貝到后端java服務(wù)器
開始部署jenkins：
1.上傳jdk
[root@jenkins-server ~]# tar -xvzf jdk-8u211-linux-x64.tar.gz -C /usr/local/
[root@jenkins-server ~]# cd /usr/local/
[root@jenkins-server local]# mv jdk1.8.0_211/ java
2.安裝tomcat
[root@jenkins-server ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.45/bin/apache-tomcat-8.5.42.tar.gz
[root@jenkins-server ~]# tar -xvzf apache-tomcat-8.5.45.tar.gz -C /usr/local/
[root@jenkins-server ~]# cd /usr/local/
[root@jenkins-server local]# mv apache-tomcat-8.5.45/ tomcat
3.安裝maven
[root@jenkins-server ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz
[root@jenkins-server ~]# tar -xvzf apache-maven-3.5.4-bin.tar.gz -C /usr/local/java/
[root@jenkins-server ~]# cd /usr/local/java
[root@jenkins-server java]# mv apache-maven-3.5.4/ maven
設(shè)置變量:
[root@jenkins-server ~]# vim /etc/profile
JAVA_HOME=/usr/local/java
MAVEN_HOME=/usr/local/java/maven
PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL JAVA_HOME MAVEN_HOME
[root@jenkins-server ~]# source /etc/profile
驗(yàn)證:
[root@jenkins-server ~]# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)
[root@jenkins-server ~]# mvn -v
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-18T02:33:14+08:00)
Maven home: /usr/local/java/maven
Java version: 1.8.0_191, vendor: Oracle Corporation, runtime: /usr/local/java/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-693.el7.x86_64", arch: "amd64", family: "unix"
下載jenkins的安裝包:
安裝jenkins:2.196 ----通過官網(wǎng)直接下載war包婶恼。
官網(wǎng):http://updates.jenkins-ci.org/download/war/
[root@jenkins-server ~]# wget http://updates.jenkins-ci.org/download/war/2.196/jenkins.war
部署jenkins
[root@jenkins-server ~]# cd /usr/local/tomcat/webapps/
[root@jenkins-server webapps]# rm -rf *
[root@jenkins-server webapps]# cp /root/jenkins.war .
[root@jenkins-server webapps]# ../bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/java
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

如果一直在這個(gè)頁面不跳轉(zhuǎn)稚配，可以看看Tomcat的啟動(dòng)情況畅涂，如果有兩個(gè)Tomcat進(jìn)程，就全部殺死道川，再重啟Tomcat午衰，如果不行，就多等一會(huì)兒吧冒萄，嘻嘻嘻....

[root@jenkins-server ~]# cat /opt/jenkins/secrets/initialAdminPassword

插件下載需要很長很長一段時(shí)間，慢的話可能需要一兩個(gè)小時(shí)哦

3.安裝插件
安裝插件:
所需的插件:
? Maven插件 Maven Integration plugin
? 發(fā)布插件 Deploy to container Plugin
需要安裝插件如下：
=============================================================
安裝插件Deploy to container ---支持自動(dòng)化代碼部署到tomcat容器
Git plugin 可能已經(jīng)安裝
Maven Integration :jenkins利用Maven編譯宦言，打包所需插件
Publish Over SSH :通過ssh連接
ssh 插件
安裝過程:
系統(tǒng)管理--->插件管理---->可選插件--->過濾Deploy to container---->勾選--->直接安裝

key:指的是jenkins服務(wù)器用哪個(gè)用戶去遠(yuǎn)程連接程序服務(wù)器就是那個(gè)用戶的私鑰扇单。
[root@jenkins-server .ssh]# cat id_rsa
4.添加遠(yuǎn)程ssh-server:
1564334945023.png
5商模、配置jdk奠旺，maven命令蜘澜，全局配置

6.構(gòu)建發(fā)布任務(wù)

此處源碼鏈接為文章開頭給的github倉庫地址
1564335823407.png
此處SSH Server 中Name應(yīng)與前面設(shè)置的一樣
7.調(diào)用maven命令

8.部署java服務(wù)器，做jenkins打包上線
[root@java-server ~]# mkdir -p /data/application
上傳jdk
[root@java-server ~]# tar -xvzf jdk-8u211-linux-x64.tar.gz -C /usr/local/
[root@java-server ~]# cd /usr/local/
[root@java-server local]# mv jdk1.8.0_211/ java
下載tomcat
[root@java-server ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.42/bin/apache-tomcat-8.5.42.tar.gz
[root@java-server ~]# tar xzf apache-tomcat-8.5.42.tar.gz -C /data/application/
[root@java-server ~]# cd /data/application/
[root@java-server application]# mv apache-tomcat-8.5.42/ tomcat
設(shè)置環(huán)境變量
[root@java-server ~]# vim /etc/profile
export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/data/application/tomcat
[root@java-server ~]# source /etc/profile
測試:
[root@java-server ~]# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)
刪除tomcat默認(rèn)發(fā)布目錄下面的內(nèi)容:
[root@java-server ~]# rm -rf /data/application/tomcat/webapps/*
[root@java-server ~]# cd /data/application/tomcat/webapps/
[root@java-server webapps]# ls
創(chuàng)建目錄和腳本:
[root@java-server ~]# mkdir /opt/script #創(chuàng)建腳本目錄
[root@java-server ~]# vim /opt/script/app-jenkins.sh #創(chuàng)建腳本
腳本內(nèi)容在后面：
[root@java-server ~]# chmod +x /opt/script/app-jenkins.sh #添加執(zhí)行權(quán)限
腳本內(nèi)容:
[root@java-server script]# cat app-jenkins.sh
#!/usr/bin/bash
#本腳本適用于jenkins持續(xù)集成响疚，實(shí)現(xiàn)備份war包到代碼更新上線鄙信！使用時(shí)請(qǐng)注意全局變量。
