第三章 Jenkins参数及web项目

一、创建本地Git仓库

1.上传java包

1.上传jar包
[root@m01 ~]# rz sholdboyedu-jenkins-jar.zip

2.解压包
[root@m01 ~]# unzip sholdboyedu-jenkins-jar.zip

2.创建gitlab仓库

1.删除原有Git库
[root@jenkins ~]# cd sholdboyedu-jenkins-jar/
[root@jenkins ~/sholdboyedu-jenkins-jar]# rm -rf .git

2.新建Git库
[root@jenkins ~/sholdboyedu-jenkins-jar]# git init
Initialized empty Git repository in /root/sholdboyedu-jenkins-jar/.git/
[root@m01 ~/sholdboyedu-jenkins-jar]# git remote add origin http://10.0.0.61/root/sholdboyedu-jenkins-java-jar.git
[root@m01 ~/sholdboyedu-jenkins-jar]# git config -l
user.name=Administrator
user.email=admin@example.com
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
remote.origin.url=http://10.0.0.61/root/sholdboyedu-jenkins-java-jar.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*

3.推送到远程Gitlab库
[root@m01 ~/sholdboyedu-jenkins-jar]# git add .
[root@m01 ~/sholdboyedu-jenkins-jar]# git commit  -m 'init'
[master (root-commit) 7c0e374] init

3.创建jenkins项目

二、jenkins构建maven

在Jenkins集成服务器上，我们需要安装Maven来编译和打包项目。

1.安装maven包

#1.下载安装包
[root@jenkins /opt]# wget https://mirrors.aliyun.com/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
--2020-12-24 10:16:04--  https://mirrors.aliyun.com/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

HTTP request sent, awaiting response... 200 OK
Length: 9506321 (9.1M) [application/octet-stream]
Saving to: ‘apache-maven-3.6.3-bin.tar.gz’

100%[===============================================================================>] 9,506,321   15.4MB/s   in 0.6s   

2020-12-24 10:16:05 (15.4 MB/s) - ‘apache-maven-3.6.3-bin.tar.gz’ saved [9506321/9506321]

2.安装jdk

1.安装jdk
[root@jenkins ~]# yum install java-1.8.0-openjdk* -y

2.检查jdk版本
[root@jenkins ~]# java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)

3.安装maven

[root@jenkins /opt]# tar xf apache-maven-3.6.3-bin.tar.gz 
[root@jenkins /opt]# ll
total 9284
drwxr-xr-x 6 root root      99 Dec 24 10:19 apache-maven-3.6.3
-rw-r--r-- 1 root root 9506321 Jul  3 12:01 apache-maven-3.6.3-bin.tar.gz
drwxr-xr-x 4 root root     111 Dec 23 20:25 opt
[root@jenkins /opt]# mv apache-maven-3.6.3 /usr/local/
[root@jenkins /opt]# ll /usr/local/
total 0
drwxr-xr-x  6 root root 99 Dec 24 10:19 apache-maven-3.6.3

4、添加环境变量

1.配置环境变量
[root@jenkins /usr/local/apache-maven-3.6.3]# vim /etc/profile.d/maven.sh
export PATH=/usr/local/apache-maven-3.6.3/bin:$PATH

2.重载环境变量
[root@jenkins /usr/local/apache-maven-3.6.3]# source /etc/profile

3.测试
[root@jenkins ~]# mvn -version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/apache-maven-3.6.3
Java version: 1.8.0_275, vendor: Red Hat, Inc., runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.275.b01-0.el7_9.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"

5、配置jenkins适配moven

配置完以上，需要保存。

6、使jenkins调用maven

设置完环境变量，需要点击保存。

7、安装maven插件

8、创建maven本地仓库

1.创建maven仓库
[root@jenkins /usr/local/apache-maven-3.6.3/conf]# mkdir -pv /data/software/repository
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/software’
mkdir: created directory ‘/data/software/repository’

2.授权maven仓库
[root@instance-gvpb80ao ~]# chown jenkins.jenkins /data/software/repository/

9、修改maven配置

[root@jenkins ~]# vim /usr/local/apache-maven-3.6.3/conf/settings.xml 

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  
  <!--本地仓库-->          
  <localRepository>/data/software/repository</localRepository>
  
  <mirrors>
    <!--阿里云镜像-->
    <mirror>
      <id>aliyun-maven</id>
      <mirrorOf>central</mirrorOf>
      <name>aliyun maven mirror</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    </mirror>
  </mirrors>
    ...
    ...
</settings>

测试maven

三、部署Tomcat

1、安装JDK

[root@web01 ~]# yum install java-1.8.0-openjdk* -y

2、下载tomcat安装包

[root@web01 ~]# cd /opt/
[root@web01 /opt]# wget https://ftp.wayne.edu/apache/tomcat/tomcat-9/v9.0.41/bin/apache-tomcat-9.0.41.tar.gz
--2020-12-25 16:56:29--  https://ftp.wayne.edu/apache/tomcat/tomcat-9/v9.0.41/bin/apache-tomcat-9.0.41.tar.gz

HTTP request sent, awaiting response... 200 OK
Length: 11442169 (11M) [application/x-gzip]
Saving to: ‘apache-tomcat-9.0.41.tar.gz’

100%[===============================================================================>] 11,442,169   476KB/s   in 32s

3、解压安装

[root@web01 /opt]# tar xf apache-tomcat-9.0.41.tar.gz 
[root@web01 /opt]# ll
total 11176
drwxr-xr-x 9 root root      220 Dec 25 16:57 apache-tomcat-9.0.41
-rw-r--r-- 1 root root 11442169 Dec  3 20:42 apache-tomcat-9.0.41.tar.gz
[root@web01 /opt]# mv apache-tomcat-9.0.41 /usr/local/tomcat-9.0.41
[root@web01 /opt]# ln -s /usr/local/tomcat-9.0.41 /usr/local/tomcat
[root@web01 /opt]# cd /usr/local/tomcat

4、添加环境变量

[root@web01 /usr/local/tomcat]# vim /etc/profile.d/tomcat.sh
export PATH=/usr/local/tomcat-9.0.41/bin/:$PATH             
                                                         
[root@web01 /usr/local/tomcat]# source  /etc/profile

5、添加用户

# 1、添加tomcat用户
[root@web01 /usr/local/tomcat]# vim /usr/local/tomcat/conf/tomcat-users.xml 
...  ...
    <role rolename="tomcat"/>
    <role rolename="role1"/>
    <role rolename="manager-script"/>
    <role rolename="manager-gui"/>
    <role rolename="manager-status"/>
    <role rolename="admin-gui"/>
    <role rolename="admin-script"/>
    <user username="tomcat" password="tomcat" roles="manager-gui,manager-script,tomcat,admin-gui,admin-script"/>

# 2、注释权限验证
[root@web01 /usr/local/tomcat]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml
  <!--
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127.d+.d+.d+|::1|0:0:0:0:0:0:0:1" />
  -->

6、启动tomcat

[root@test-web /usr/local/apache-tomcat-9.0.41]# ./bin/startup.sh 
Using CATALINA_BASE:   /usr/local/apache-tomcat-9.0.41
Using CATALINA_HOME:   /usr/local/apache-tomcat-9.0.41
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-9.0.41/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/apache-tomcat-9.0.41/bin/bootstrap.jar:/usr/local/apache-tomcat-9.0.41/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.

7、验证

四、添加ssh免密认证

[root@jenkins ~]# ssh-keygen
[root@jenkins ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.0.0.7
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@10.0.0.7's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@10.0.0.7'"
and check to make sure that only the key(s) you wanted were added.

五、将war包推送至tomcat容器

1、下载jenkins链接tomcat容器的插件

Deploy to container

2、创建tomcat容器凭证

3、推送war包到tomcat容器
