Jenkins流水线项目发布流程

本次环境为：

主机名	IP地址	安装的应用	系统版本
jenkins	192.168.100.1	tomcat jenkins	RedHat 8

tomcat、jenkins安装配置步骤请见：Jenkins配置

准备工作：

[root@jenkins ~]# systemctl disable --now firewalld
[root@jenkins ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
[root@jenkins ~]# setenforce 0
[root@jenkins ~]# yum -y install maven git

安装Pipeline、Publish Over SSH、Publish Over SSH、SSH Build Agents、Git、GitHub、GitLab、Gitee插件（出现错误多装几次）

Gitee配置公钥

//创建密钥
[root@jenkins ~]# ssh-keygen -t rsa -b 2048 -C "[e-mail]" -N "" -f /root/.ssh/id_rsa
Generating public/private rsa key pair.
Created directory \'/root/.ssh\'.
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:MtYf5/dFCJuwZ37E4sO3as6b5r0i3xbdoArF1ABiQv8 [e-mail]
The key\'s randomart image is:
+---[RSA 2048]----+

|     + .  . .    |
|      .  o. .    |

|         ...* +..|
|          o.+O.o.|
|           BO==..|

//查看公钥
[root@jenkins ~]# cat /root/.ssh/id_rsa.pub

登录Gitee然后将公钥复制进去

Jenkins 创建凭据

选择ssh username with private key类型（Jenkins要为最新版） —— 添加私钥

//查看私钥
[root@jenkins ~]# cat /root/.ssh/id_rsa
