jenkins 部署 和构建java项目

1.准备环境依赖 jdk

yum install jdk-8u261-linux-x64.rpm

2.下载jenkins

yum install https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat/jenkins-2.306-1.1.noarch.rpm

3.起服务

systemct enable jenkins
systemctl start jenkins

4.关闭防火墙和selinux

systemctl stop firewalld
setenforce 0

5.http://IP:8080 web界面访问

6.web界面安装
6.1 选择安装推荐的插件

6.2创建管理员用户

6.3安装完成

2.构建java项目
2.1下载源码包

[root@localhost ~]# git clone https://gitee.com/JPressProjects/jpress.git

2.2 在gitee上创建仓库

2.3 将项目推送到gitee仓库

[root@localhost jpress]# git remote add origin http://192.168.196.176:8090/dev/jress.git
[root@localhost jpress]# git push -u origin --all

台虚拟机部署tomcat环境
2.4.1 在官网下载tomcat

下载网址：https://tomcat.apache.org/download-80.cgi#8.5.81

[root@localhost ~]# tar xf apache-tomcat-8.5.81.tar.gz 
[root@localhost ~]# mv apache-tomcat-8.5.81 /usr/local/
[root@localhost ~]# ln -s /usr/local/apache-tomcat-8.5.81/ /usr/local/tomcat
[root@localhost ~]#  echo "CATALINA_HOME=/usr/local/tomcat" >> /etc/profile
[root@localhost ~]# source /etc/profile
查看熵池的大小：
[root@localhost ~]# cat /proc/sys/kernel/random/entropy_avail
718
熵池可以解决tomcat启动慢的问题，通过安装rng服务来解决
[root@localhost ~]# yum install rng-tools
[root@localhost ~]# systemctl enable --now rngd
[root@localhost ~]# cat /proc/sys/kernel/random/entropy_avail
3086

2.4.2 在/usr/local/tomcat/conf/tomcat-users.xml 文件中写入以下内容 —添加角色和用户

2.4.3 在/usr/local/tomcat/webapps/host-manager/META-INF/context.xml中添加网段

2.4.5 启动tomcat

[root@node4 ~]# /usr/local/tomcat/bin/startup.sh

访问：IP：8080

3. 下载maven插件

下载maven
[root@localhost ~]# wget -c https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz --no-check-certificate
解压到指定路径
[root@localhost ~]# tar xf apache-maven-3.6.3-bin.tar.gz -C /usr/local
创建连接
[root@localhost ~]# ln -s /usr/local/apache-maven-3.6.3/ /usr/local/maven
在文件中写入内容
[root@localhost ~]# cat /etc/profile.d/maven.sh
export M2_HOME=/usr/local/maven
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
[root@localhost ~]# source /etc/profile.d/maven.sh
测试maven是否安装成功
[root@localhost ~]# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
