先來一張報錯信息，真的是拉不到頭。。

一、首先解決第一個問題，將插件下載地址換為國內(nèi)源

官方源：https://updates.jenkins.io/update-center.json
國內(nèi)源： https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/current/update-center.json
國內(nèi)源2：http://mirror.xmission.com/jenkins/updates/update-center.json

修改配置文件

• 進入jenkins安裝目錄下的/updates/default.json ，將其中的updates.jenkins-ci.org/download 替換為mirrors.tuna.tsinghua.edu.cn/jenkins ，
• 有些 jenkins 版本當(dāng)中，是將updates.jenkins.io/download 替換為mirrors.tuna.tsinghua.edu.cn/jenkins
• 然后，把 www.google.com 修改為 www.baidu.com

sed -i 's#http://updates.jenkins-ci.org/download#https://mirrors.tuna.tsinghua.edu.cn/jenkins#g' default.json
sed -i 's#http://www.google.com#https://www.baidu.com#g' default.json

重啟jenkins

二、在解決插件安裝問題的過程中，我發(fā)現(xiàn)我的jenkins版本過低了，導(dǎo)致安裝的一些插件或者已安裝的插件依賴的插件不兼容，所以第二個問題，升級jenkins

我這里是用docker安裝的jenkins，安裝可以看我之前的文章，所以要先進到j(luò)enkins容器

# 進到j(luò)enkins.war文件所在的目錄
root@456fcdc45cdf:/var/jenkins_home# cd /usr/share/jenkins/
root@456fcdc45cdf:/usr/share/jenkins# ls
jenkins.war  ref
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
# 備份原war包
root@456fcdc45cdf:/usr/share/jenkins# cp jenkins.war jenkins.war.2.328.bak
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins# ls
jenkins.war  jenkins.war.2.328.bak  ref
# 新建文件夾，存儲新的war包
root@456fcdc45cdf:/usr/share/jenkins# mkdir other-version
root@456fcdc45cdf:/usr/share/jenkins# cd other-version/
# 下載最新的war包
root@456fcdc45cdf:/usr/share/jenkins/other-version# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

root@456fcdc45cdf:/usr/share/jenkins# ls
jenkins.war  jenkins.war.2.328.bak  other-version  ref
# 刪除原war包
root@456fcdc45cdf:/usr/share/jenkins# rm jenkins.war
root@456fcdc45cdf:/usr/share/jenkins# ls
jenkins.war.2.328.bak  other-version  ref
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins#
root@456fcdc45cdf:/usr/share/jenkins# cd other-version/
# 替換war包
root@456fcdc45cdf:/usr/share/jenkins/other-version# mv jenkins.war ../
root@456fcdc45cdf:/usr/share/jenkins/other-version#
root@456fcdc45cdf:/usr/share/jenkins/other-version#
root@456fcdc45cdf:/usr/share/jenkins/other-version# ls
root@456fcdc45cdf:/usr/share/jenkins/other-version# cd ..
root@456fcdc45cdf:/usr/share/jenkins# ls
jenkins.war  jenkins.war.2.328.bak  other-version  ref
root@456fcdc45cdf:/usr/share/jenkins#
# 退出容器
root@456fcdc45cdf:/usr/share/jenkins# exit
[root@qa work]#
# 重啟
[root@qa work]# docker restart jenkins
jenkins

jenkins下載官網(wǎng)：https://www.jenkins.io/download/
下載最新版本鏈接：http://mirrors.jenkins.io/war-stable/latest/jenkins.war
所有的war包地址：https://mirrors.tuna.tsinghua.edu.cn/jenkins/war/

三、替換jenkins.war文件后docker鏡像文件無法啟動解決方法

  777  docker ps -a
  778  docker cp 456f:/usr/share/jenkins/jenkins.war ./
  779  ll
  780  docker cp 456f:/usr/share/jenkins/jenkins.war.2.328.bak ./
  781  ll
  782  rm -rf jenkins.war
  783  mv jenkins.war.2.328.bak jenkins.war
  784  docker cp ./jenkins.war 456f:/usr/share/jenkins/jenkins.war
  785  docker start 456f
  786  docker ps

  795  ll
  796  docker ps
  797  docekr logs -f 456f
  798  docker logs -f 456f
  799  ll
  800  mv jenkins.war jenkins.war.2.328.bak
  801  docker exec -it 456f bash
  802  docker exec -it 456f -u root /bin/bash
  803  docker exec -it jenkins -u root /bin/bash
  804  rz
  805  docker ps
  806  docker cp ./jenkins.war 456f:usr/share/jenkins
  807  docker restart 456f
  808  docekr ps
  809  docker ps
  810  docker logs -f 456f
  811  history

修復(fù)問題后截圖
注：因更換了war文件，ssh憑證和java-web文件都需要重新更換，更換后重新啟動即可
