JAVA环境搭建

##构建JAVA环境
[root@jenkins ~]# tar xf jdk-8u181-linux-x64.tar -C /usr/local/
[root@jenkins ~]# mv /usr/local/jdk1.8.0_181 /usr/local/java
[root@jenkins ~]# vim /etc/profile
export JAVA_HOME=/usr/local/java 
export PATH=$JAVA_HOME/bin:$PATH 
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 
[root@jenkins ~]# source /etc/profile

[root@jenkins ~]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

##部署tomcat服务<tomcat.apache.org>
[root@jenkins ~]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz
[root@jenkins ~]# tar xf apache-tomcat-9.0.13.tar.gz -C /usr/local/
[root@jenkins local]# mv apache-tomcat-9.0.13 tomcat
[root@jenkins ~]# rm -rf /usr/local/tomcat/webapps/*

##部署maven服务<maven.apache.org>
[root@jenkins ~]# wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.6.0/binaries/apache-maven-3.6.0-bin.tar.gz
[root@jenkins ~]# tar xf apache-maven-3.6.0-bin.tar.gz -C /usr/local/
[root@jenkins local]# mv apache-maven-3.6.0 maven
[root@jenkins ~]# vim /etc/profile
export MAVEN_HOME=/usr/local/maven
export PATH=$MAVEN_HOME/bin:$PATH
[root@jenkins ~]# source /etc/profile

##部署Jenkins服务<jenkins.io>
[root@jenkins ~]# vim /etc/profile.d/jenkins.sh
export  JENKINS_HOME=/usr/local/jenkins

[root@jenkins ~]# vim /usr/local/tomcat9/bin/catalina.sh
export  JENKINS_HOME=/usr/local/jenkins

#以上两部为配置jenkins安装插件的目录
[root@jenkins ~]# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war
[root@jenkins ~]# unzip jenkins.war -d /usr/local/tomcat/webapps/ROOT
[root@jenkins ~]# ln -s /usr/local/tomcat/bin/startup.sh /usr/bin/tomcat
[root@jenkins ~]# chmod a+x /usr/bin/tomcat
[root@jenkins ~]# tomcat

/ Jenkins 自动化打包、部署、发布过程 /

第一部分: Jenkins自动化拉取gitlab上的代码

1.安装gitlab插件

image.png
2.创建gitlab用户添加至项目中并具备管理权限 image.png

image.png
3.系统管理之全局插件管理 image.png

image.png
4.构建项目 image.png

image.png
5.点击立即构建并生成报文 image.png
第二部分: 将代码自动部署至测试环境 1.新建新项目wangle_deploy image.png
image.png

2.webserver生成密钥对添加至gitlab/wangle项目中的Deploy key & SSH Key.

[root@webserver ~]# useradd wangle
[root@webserver ~]# echo "wangle1115" | passwd --stdin wangle
[root@webserver ~]# ssh-keygen
[root@webserver ~]# cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDDDmD9j7NTXiabhBXpf3PHSv8FZ82gPv4iaBLcWGc09YRpWfi6lAyMXaoVqoduUbVcF7m4klJ+/55xAekma1/Yi2hjZrbFvNSj5f96f+CVTtB18IXI9l6u9Pgh7mC7vZU796e8x7QzRS4rH0o/uOiVe5ecyT3Noy5/RwbhGYIL+KhGlxrn+pESXE4NyYGuSijaNkuc76VRgHTMHM3fuv9dCpU3nn4RYd6VY3HcsubAM8Z2ELM1/G1FT/mji0DgUq4CRKK7avol6xPa+f+hk203FFOVv9BuhS6/xEixHTV/eND1/RezvPnY8Vg+DlgpYpAVcwpWGTe27VmM2tffhVgl root@webserver

[root@webserver ~]# su - wangle
[wangle@webserver ~]$ ssh-keygen -t rsa
[wangle@webserver ~]$ cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCq7s09/WRXN4sJHvgQYCgMwGBBUCro65UZHu6Y5uFzzL0TUn1uhzfEU23nfaCznVlWdIVIYh+oO4lr1ewRkWYk6aAmIfYgSF3GZ6Lbeb6bixLLP/b3lt0Sf4VYWHZJhCKqMwrGjjNXZTz66b65X8HQJinTWDEv8KEVlvQS3sCWtBTS5mKh28Q2RTdzqJA8gbtaOHDsahClkV26KJr+4oXTPl4ofaJKhs5I7/2XvMYz1w5OuZzQcxGRxFivjQkIJN/bN+oTEhP5VRC93QJyw9ttlyy9G9Ep3ZzxpZyqRVPeKh9wTWKlT886igGlp/DAd5Dx6oxh+3zTgjaYGnGRE+6P wangle@webserver


[root@webserver ~]# usermod -aG wheel wangle
[root@webserver ~]# id wangle
uid=1000(wangle) gid=1000(wangle) 组=1000(wangle),10(wheel)

[wangle@webserver ~]$ vim Deploy
#!/usr/bin/env bash
#
##Author: liuchao
##Email: bavduer@163.com
##Github: https://github.com/bavdu

##clone wangle.git to locahost.
git clone git@gitlab.qfcc.com:bavdu/wangle.git
cd wangle
git pull

##transfer project file to remote computer.
sudo setfacl -m u:wangle:rwx /usr/share/nginx/html/
cp -rf ./wangle/* /usr/share/nginx/html/

[wangle@webserver ~]$ chmod a+x Deploy

3.将Jenkins服务器中的root用户的密钥认证到webserver中的wangle用户

[root@jenkins ~]# ssh-copy-id wangle@192.168.13.12
-认证完成之后测试链接

4.立即构建项目进行测试

第三部分: GitLab触发jenkins构建项目 1.安装Jenkins插件 image.png

2.生成随机token令牌

[root@jenkins ~]# openssl rand -hex 12
2f24fd87f25f7efa1e7e8688

3.构建项目触发器 image.png

4.配置gitlab webhook<点击Test显示201则表示成功>

http://jenkins.qfcc.com:8080/buildByToken/build?job=项目名称&token=身份令牌token值

5.打开gitlab的push权限, 上传代码进行测试 image.png
