Gitlab+Jenkins學習之路（十三）之發佈Java項目到tomcat

• 1、新建一臺虛擬機安裝tomcat

（1）安裝JDK
官網下載jdk：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
下載jdk8，放到/usr/local/src/目錄下
[root@linux-node3 ~]# tar -zxvf jdk-8u151-linux-x64.tar.gz
[root@linux-node3 ~]# mv jdk1.8.0_151 /usr/local/jdk1.8
[root@linux-node3 ~]# vim /etc/profile
增長以下內容：
JAVA_HOME=/usr/local/jdk1.8/
JAVA_BIN=/usr/local/jdk1.8/bin
JRE_HOME=/usr/local/jdk1.8/jre
PATH=$PATH:/usr/local/jdk1.8/bin:/usr/local/jdk1.8/jre/bin
CLASSPATH=/usr/local/jdk1.8/jre/lib:/usr/local/jdk1.8/lib:/usr/local/jdk1.8/jre/lib/charsets.jar
[root@linux-node3 ~]# source /etc/profile
[root@linux-node3 ~]# java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
 
（2）安裝tomcat
[root@linux-node3 ~]# wget http://apache.fayea.com/tomcat/tomcat-8/v8.5.20/bin/apache-tomcat-8.5.20.tar.gz
[root@linux-node3 ~]# tar -zxvf apache-tomcat-8.5.24.tar.gz 
[root@linux-node3 ~]# mv apache-tomcat-8.5.24 /usr/local/tomcat
[root@linux-node3 ~]# /usr/local/tomcat/bin/startup.sh 
[root@linux-node3 ~]# netstat -tulnp |grep 8080
tcp6       0      0 :::8080                 :::*                    LISTEN      3765/java 
 
提示：三個端口8080爲提供web服務的端口，8005爲管理端口，8009端口爲第三方服務調用的端口，好比httpd和Tomcat結合時會用到
 
（3）配置tomcat
[root@linux-node3 ~]# vim /usr/local/tomcat/conf/tomcat-users.xml 
<tomcat-users>
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user name="admin" password="admin123456" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />
</tomcat-users>
[root@linux-node3 ~]# /usr/local/tomcat/bin/shutdown.sh 
[root@linux-node3 ~]# /usr/local/tomcat/bin/startup.sh 
 
在訪問tomcat時，點擊"manager webapp"會跳出一個驗證彈框，輸入用戶名密碼

會跳轉到如下界面，說明用戶名密碼無誤，如圖：

 

• 2、下載zrlog的java代碼push到gitlab上 

（1）下載zrlog的代碼
[root@linux-node2 home]# wget https://codeload.github.com/94fzb/zrlog/zip/master
--2017-12-25 11:02:45--  https://codeload.github.com/94fzb/zrlog/zip/master

2017-12-25 11:02:56 (189 KB/s) - ‘master’ saved [1669502]
[root@linux-node2 home]# du -sh
1.7M.
[root@linux-node2 home]# du -sh master
1.6Mmaster
 
（2）解壓
[root@linux-node2 home]# yum install -y unzip
[root@linux-node2 home]# unzip master
 
（3）初始化倉庫，並將zrlog的代碼push到gitlab
[root@linux-node2 home]# mkdir Java
[root@linux-node2 Java]# mv zrlog-master/* Java/
[root@linux-node2 Java]# git remote add orgin git@192.168.56.11:java/zrlog.git
[root@linux-node2 Java]# git add .
[root@linux-node2 Java]# git commit -m "add origin"
# On branch master

• 3、新建一個maven項目zr_blog

（1）新建項目

登陸jenkins，點擊「新建」，任務名稱自定義（zr_blog）

選擇「構建一個maven項目」

點擊「肯定」

（2）配置項目

源碼管理

選擇 「git」, Repository URL填寫你的git地址，並配置對應的key，你們最好事前先在jenkins這臺機器上可以直接遠程git操做私有倉庫

 構建觸發器、構建環境、Pre Steps保持默認

 Build

「Root POM」爲pom.xml, Goals and options 填寫 clean install -D maven.test.skip=true

 Post Steps、構建設置保持默認

 構建後操做

 點擊「增長構建後操做步驟」選擇「Deploy war/ear to a container」,「WAR/EAR files」填寫「**/*.war」,Contex path留空，Containers選擇Tomcat 8.x，Tomcat URL填寫要把war包發佈到的那臺機器的url，如http://192.168.56.13:8080

 Credentials這裏須要點擊右側的Add，添加用戶名和密碼

 

點擊"當即構建"查看控制檯信息，如圖：

 

（3）查看發佈結果

查看linux-node3的webapps目錄，會有相對應的war包，並已經進行解壓，使用瀏覽器訪問

[root@linux-node3 ~]# ll /usr/local/tomcat/webapps/
total 7160
drwxr-x--- 14 root root    4096 Dec 25 03:08 docs
drwxr-x---  6 root root    4096 Dec 25 03:08 examples
