2. 与jenkins集成实现ci/cd
jenkins 工具
自动化代码上线
核心功能支持大量的插件
jenkins java代码
比如之前做的小鸟飞飞是纯html页面
如果想换个小鸟的颜色怎么做呢
html文件 站点
开发写好代码传给运维 然后运维进行上传解压
代码版本管理软件
git: github
git check out
git tag
shell脚本
java类型
java项目代码上线链接
java
需要编译
.cless
2.1 安装gitlab并上传代码
#上传代码包
[root@k8s-node2 jenkins-k8s]# ll
total 890176
-rw-r--r-- 1 root root 9128610 Sep 18 10:48 apache-tomcat-8.0.27.tar.gz

-rw-r--r-- 1 root root 91014 Sep 18 10:49 xiaoniaofeifei.zip
#安装
[root@k8s-node2 jenkins-k8s]# rpm -ivh gitlab-ce-11.9.11-ce.0.el7.x86\_64.rpm
#配置
vim /etc/gitlab/gitlab.rb
external_url 'http://10.0.0.13'
prometheus_monitoring['enable'] = false
#应用并启动服务
gitlab-ctl reconfigure
#使用浏览器访问http://10.0.0.13,修改root用户密码,创建project
创建项目
[root@k8s-node2 opt]# cd /srv/
[root@k8s-node2 srv]# ls
[root@k8s-node2 srv]# git clone https://gitlab.com/xhang/gitlab.git
Cloning into 'gitlab'...
#确保有git命令
[root@k8s-node2 srv]# which git
/usr/bin/git
[root@k8s-node2 srv]# git config --global user.name "Administrator"
[root@k8s-node2 srv]# git config --global user.email "admin@example.com"
[root@k8s-node2 srv]# cat /root/.gitconfig
[user]
name = Administrator
email = admin@example.com
[root@k8s-node2 srv]# mv /root/jenkins-k8s/xiaoniaofeifei.zip .
[root@k8s-node2 srv]# unzip xiaoniaofeifei.zip
[root@k8s-node2 srv]# ls

上传代码
git init
git remote add origin http://10.0.0.13/root/xiaoniao.git
git add .
git commit -m "Initial commit"

[root@k8s-node2 srv]# git push -u origin master
Username for 'http://10.0.0.13': root
Password for 'http://root@10.0.0.13':
上传成功
2.2 安装jenkins,并自动构建docker镜像
node1上安装jenkins
[root@k8s-node1 opt]# ll
total 334020
-rw-r--r-- 1 root root 9128610 Sep 18 11:53 apache-tomcat-8.0.27.tar.gz
-rw-r--r-- 1 root root 166044032 Sep 18 11:54 jdk-8u102-linux-x64.rpm
-rw-r--r-- 1 root root 89566714 Sep 18 11:54 jenkin-data.tar.gz
-rw-r--r-- 1 root root 77289987 Sep 18 11:54 jenkins.war
rpm -ivh jdk-8u102-linux-x64.rpm
mkdir /app
tar xf apache-tomcat-8.0.27.tar.gz -C /app
rm -fr /app/apache-tomcat-8.0.27/webapps/*
mv jenkins.war /app/apache-tomcat-8.0.27/webapps/ROOT.war
tar xf jenkin-data.tar.gz -C /root
/app/apache-tomcat-8.0.27/bin/startup.sh
netstat -lntup
2.3 浏览器访问jenkins
访问http://10.0.0.12:8080/,默认账号密码admin:123456
2.4 配置jenkins拉取gitlab代码凭据
a:在jenkins上生成秘钥对
#生成秘钥 一路回车
[root@k8s-node1 opt]# ssh-keygen -t rsa
[root@k8s-node1 opt]# ls /root/.ssh/
id_rsa id_rsa.pub known_hosts
b:复制公钥粘贴gitlab上
新建秘钥的进入方法
c:在node1上查看秘钥
[root@k8s-node1 opt]# cat /root/.ssh/id\_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCrlIgDVptvmipg00CP7P955Nbn2h+oy06hUiYWE+htG6VjLSCFjEhrxgXOCX2EAKGLgveWA46MLt4XN2Gi4E1H3aDsM/gBu8D+4487bKuLKv1ZeMeWECcDKL16cjtSQw6ShsCLBwh3aq5TT85I/ypUYMsQ1+N4Iiv4i3g3ozn0yPsyMq9rekW+nHbs8eJL1OzIue6hL78AgI8QuZ7QaCQ5TJDmCwKuLC+B+6ajyNezSxBIlZeBuUE5lacKmvxxnX5Dqzlvf5uGrVRSgPCR6oTTDTHmx2GVHIl7BJLZH/uR4tP7gYoY9fFOM1VyJ8Pjq+XcLGYFWNQKTgxKQO/08sjr root@k8s-node1
d:jenkins上创建全局凭据
[root@k8s-node1 opt]# cat /root/.ssh/id\_rsa

自我介绍一下,小编13年上海交大毕业,曾经在小公司待过,也去过华为、OPPO等大厂,18年进入阿里一直到现在。
深知大多数大数据工程师,想要提升技能,往往是自己摸索成长或者是报班学习,但对于培训机构动则几千的学费,着实压力不小。自己不成体系的自学效果低效又漫长,而且极易碰到天花板技术停滞不前!
因此收集整理了一份《2024年大数据全套学习资料》,初衷也很简单,就是希望能够帮助到想自学提升又不知道该从何学起的朋友。
既有适合小白学习的零基础资料,也有适合3年以上经验的小伙伴深入学习提升的进阶课程,基本涵盖了95%以上大数据开发知识点,真正体系化!
由于文件比较大,这里只是将部分目录大纲截图出来,每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频,并且后续会持续更新
如果你觉得这些内容对你有帮助,可以添加VX:vip204888 (备注大数据获取)
一个人可以走的很快,但一群人才能走的更远。不论你是正从事IT行业的老鸟或是对IT行业感兴趣的新人,都欢迎扫码加入我们的的圈子(技术交流、学习资源、职场吐槽、大厂内推、面试辅导),让我们一起学习成长!
