本文详细描述了如何在Ubuntu22.04服务器上卸载并重装Jenkins，重点在于解决重启后非默认8080端口的问题，涉及停止服务、卸载和清理残留文件的操作步骤。

自己想在Ubunt 22.04 服务器上重装jenkins 卸载完后重装发现启动的端口不是默认的8080端口，网上找的资料都不是很全，所以自己记录下。

自己装过的版本

1.先停掉jenkins服务

sudo systemctl stop jenkins

2.取消Jenkins自启动和卸载

sudo systemctl disable jenkins
sudo apt-get remove jenkins

3.卸载jenkins相关配置

sudo apt purge jenkins
sudo apt purge --auto-remove jenkins

4.关键的地方来了，搞完上面3步还没完。这样操作jenkins还是有很多残留的文件的，如果不删除，当你重新安装jenkins后会发现之前修改完jenkins的端口还是出现了，不是默认的8080.

# 切换root用户
su root

# 进入根目录
cd /

# 查看有关jenkins文件夹
find / -iname "*jenkins*"

5. 不是把查出来有关的jenkins文件都删除掉，如果服务器此时也装了gitlab 也会扫描出来的。

具体问题具体分析。

6.根据自己的情况来删除，我删除下面几个文件夹

# 缓存相关
sudo rm -rf /root/.jenkins/
sudo rm -r /var/lib/jenkins
sudo rm -r /var/cache/jenkins
# 服务启动
sudo rm -rf /etc/systemd/system/jenkins.service.d

7.重新安装jenkins，我是指定版本安装

root@MyUbuntu:~# sudo apt-get install jenkins=2.440.2
正在读取软件包列表... 完成
正在分析软件包的依赖关系树... 完成
正在读取状态信息... 完成
下列【新】软件包将被安装：

升级了 0 个软件包，新安装了 1 个软件包，要卸载 0 个软件包，有 27 个软件包未被升级。
需要下载 0 B/85.8 MB 的归档。
解压缩后会消耗 86.6 MB 的额外空间。
正在选中未选择的软件包 jenkins。

正在设置 jenkins (2.440.2) ...
Created symlink /etc/systemd/system/multi-user.target.wants/jenkins.service → /lib/systemd/system/jenkins.service.

8.看下状态，没有问题，完成。端口号也是默认的8080.
