步驟

前提

1扼仲、確保jdk已經(jīng)安裝载庭，至少是java8以上批什，如果沒(méi)有安裝卧斟，可以參考https://blog.csdn.net/Think_and_work/article/details/122842622?spm=1001.2014.3001.5502

1糠涛、下載jenkins

方式一：公眾號(hào)獲取

關(guān)注"I am Walker"援奢，回復(fù)"jenkins"獲取

方式二：官網(wǎng)下載

http://mirrors.jenkins-ci.org/redhat/
在這里可以選擇自己想要的版本

2、下載好之后移動(dòng)到linux虛擬機(jī)上

可以使用xftp進(jìn)行轉(zhuǎn)移

3忍捡、解壓

rpm -ivh jenkins-2.174-1.1.noarch.rpm

[root@localhost jenkins]# rpm -ivh jenkins-2.174-1.1.noarch.rpm 
warning: jenkins-2.174-1.1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID d50582e6: NOKEY
Preparing...                          ################################# [100%]
Updating / installing...
   1:jenkins-2.174-1.1                ################################# [100%]

4集漾、配置jenkins中的java路徑

（1）查詢java安裝路徑

[root@localhost develop]# whereis java
java: /opt/env/jdk1.8.0_202/bin/java

(2)修改/etc/init.d/jenkins文件 ，配置jdk安裝路徑

vim /etc/init.d/jenkins
下拉到candidates這個(gè)變量砸脊，然后將java的安裝路徑添加進(jìn)去

5具篇、啟動(dòng)

service jenkins start

若顯示ok即可

6、測(cè)試訪問(wèn)

默認(rèn)的端口是8080
訪問(wèn)http://ip:8080即可凌埂，ip是自己虛擬機(jī)的ip

第一次進(jìn)入比較緩慢驱显，等待進(jìn)入，之后進(jìn)入到這個(gè)頁(yè)面瞳抓，需要獲取管理員的密碼

7埃疫、獲取密碼

（1）復(fù)制該地址，然后讀取該地址的內(nèi)容即可孩哑，里面就是我們需要的密碼

（2）點(diǎn)擊繼續(xù)栓霜，進(jìn)入到插件安裝界面，一般新手的推薦選擇“安裝推薦的插件”

就會(huì)裝載這些插件了横蜒。

8胳蛮、創(chuàng)建賬戶并保存

9秤掌、實(shí)例配置

本次的安裝教程就到此為止了，后續(xù)的教程會(huì)繼續(xù)發(fā)上鹰霍。

問(wèn)題

1闻鉴、ERROR: cannot verify pkg.jenkins.io's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’:

Issued certificate has expired.

[root@localhost kit]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

解決方式：

sudo yum install -y ca-certificates

2、stat: cannot stat ‘/var/cache/jenkins’: No such file or directory

原因：
因?yàn)樵谥耙呀?jīng)安裝過(guò)jenkins茂洒，新建了jenkins文件孟岛，將其刪除即可

3、插件安裝失敗

可能是因?yàn)榘姹据^低的原因督勺，可以選擇安裝最新的版本
