Jenkins部署tomcat

编译环境（Jenkins服务器）

运行环境（web服务器）

1.部署maven编译环境（在Jenkins服务器上部署）

#1.下载maven
[root@jenkins opt]# wget https://mirrors.aliyun.com/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

#2.解压
[root@jenkins opt]# tar -xf apache-maven-3.6.3-bin.tar.gz -C /usr/local/

#3.查看java版本
[root@jenkins opt]# java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode)

#4.添加环境变量
[root@jenkins opt]# vim /etc/profile.d/java.sh
export MAVEN_HOME=/usr/local/apache-maven-3.6.3
export PATH=$MAVEN_HOME/bin:$PATH

#5.重载环境变量，测试mvn
[root@jenkins opt]# source /etc/profile
#6.测试mvn
[root@jenkins opt]# mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

2.配置Jenkins+maven

• 配置JDK

• 配置maven环境变量

• 安装maven插件

• 创建新项目

• 将源代码上传到仓库（master服务器）

#1.下载远程仓库
[root@k8s-m-01 ~]# mkdir java-tomcat
[root@k8s-m-01 java-tomcat]# git clone git@192.168.15.101:root/java-tomcat.git

#2.将源代码压缩包传到下载的仓库内并解压
[root@k8s-m-01 java-tomcat]# rz -E
rz waiting to receive.
[root@k8s-m-01 java-tomcat]# unzip chenyang0910-springboot-master.zip
[root@k8s-m-01 java-tomcat]# mv springboot/* java-tomcat/
[root@k8s-m-01 ~]# cd jenkins-tomcat/
[root@k8s-m-01 java-tomcat]# ll

-rw-r--r-- 1 root root  1664 Apr 15 20:24 pom.xml
-rw-r--r-- 1 root root    34 Aug 15 23:22 README.md
drwxr-xr-x 4 root root    30 Apr 15 20:24 src

#3.将源代码上传到远程仓库
[root@k8s-m-01 java-tomcat]# git add .
[root@k8s-m-01 java-tomcat]# git commit -m 'init' .
[root@k8s-m-01 java-tomcat]# git push -u origin master

• 创建maven仓库（Jenkins服务器）

#1.创建maven仓库
[root@jenkins ~]# mkdir -pv /data/software/repository
mkdir: 已创建目录 "/data"
mkdir: 已创建目录 "/data/software"
mkdir: 已创建目录 "/data/software/repository"
[root@jenkins ~]# chown jenkins.jenkins /data/software/repository/

#2.修改配置文件
[root@jenkins ~]# vim /usr/local/apache-maven-3.6.3/conf/settings.xml 
<settings

  <!--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>
  # 下面那个mirrors不写，切记，切记，否则就冲突了

• 测试maven仓库

选择标签开始构建（第一次编译时间稍长）

[root@jenkins ~]# ll /var/lib/jenkins/workspace/jenkins部署tomcat项目/springboot/
总用量 24
-rwxr-xr-x  1 jenkins jenkins 10070 4月  16 13:52 mvnw

运行环境

1.安装tomcat

#1.下载
[root@k8s-m-01 ~]# yum install java-1.8.0-openjdk* -y
#2.创建下载tomcat目录
[root@k8s-m-01 ~]# mkdir tomcat
[root@k8s-m-01 tomcat]# wget https://ftp.wayne.edu/apache/tomcat/tomcat-9/v9.0.52/bin/apache-tomcat-9.0.52.tar.gz
#3.解压
[root@k8s-m-01 ~]# tar -xf apache-tomcat-9.0.52.tar.gz -C /usr/local/
#4.软连接
[root@k8s-m-01 ~]# ln -s /usr/local/apache-tomcat-9.0.52/ /usr/local/tomcat
#5.添加环境变量
[root@k8s-m-01 bin]# vim /etc/profile.d/tomcat.sh
export PATH=$PATH:/usr/local/tomcat/bin
[root@k8s-m-01 bin]# source /etc/profile
#6.启动
方式一：
[root@k8s-m-01 ~]# /usr/local/apache-tomcat-9.0.52/bin/startup.sh  #启动tomcat
方式二：
[root@k8s-m-01 bin]# pwd  #启动tomcat
/usr/local/tomcat/bin     
[root@k8s-m-01 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
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.
#8.验证启动端口
[root@k8s-m-01 ~]# netstat -lntp
