環(huán)境: CentOS 7.6

方式一(不推薦使用yum安裝)

• 獲取安裝源

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

• 安裝公鑰

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

• 安裝Jenkins

yum install jenkins

• 修改配置

vim /etc/sysconfig/jenkins

修改如下:

JENKINS_PORT="8080"  #Jenkins服務(wù)訪問(wèn)端口
JENKINS_USER="root"  #用戶為root

• 修改目錄權(quán)限

chown -R root:root /var/lib/jenkins
chown -R root:root /var/cache/jenkins
chown -R root:root /var/log/jenkins

• 啟動(dòng)Jenkins

service jenkins start
ps -ef | grep jenkins

錯(cuò)誤信息:

Starting Jenkins bash: /usr/bin/java: No such file or directory      #未找到j(luò)ava文件

解決方法,創(chuàng)建java文件軟連接:

ln -s /usr/local/java/jdk1.8.0_171/bin/java /usr/bin/java

• 重新啟動(dòng)Jenkins

service jenkins restart

• 訪問(wèn)Jenkins控制臺(tái)
  瀏覽器輸入http://ip:8080,提示輸入密碼,執(zhí)行如下命令查看:

#查看初始密碼
cat /var/lib/jenkins/secrets/initialAdminPassword

提示實(shí)例已離線,解決辦法:

訪問(wèn): http://ip:8080/pluginManager/advanced 

修改升級(jí)站點(diǎn)為:
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
或者
http://mirror.xmission.com/jenkins/updates/current/update-center.json

#鏡像倉(cāng)庫(kù)倉(cāng)庫(kù)網(wǎng)站:
http://mirrors.jenkins-ci.org/status.html
#重啟Jenkins
service jenkins restart

方式二(推薦使用docker安裝)

• 拉取鏡像

docker pull jenkins/jenkins

• 添加用戶

useradd jenkins

• 掛載目錄

mkdir -p /home/jenkins            #新增jenkins目錄
vim /home/jenkins/log.properties  #編輯日志配置文件

添加如下配置:

handlers=java.util.logging.ConsoleHandler
jenkins.level=FINEST
java.util.logging.ConsoleHandler.level=FINEST

• 賦予權(quán)限

chmod -R 777 /home/jenkins                    #給目錄賦權(quán)
chown -R jenkins:jenkins /home/jenkins        #賦予用戶權(quán)限
chown -R 1000:1000 /home/jenkins
#查看權(quán)限是否設(shè)置成功
ls -nd /home/jenkins

如下顯示證明賦權(quán)成功:

drwxrwxrwx 2 1000 1000 4096 Aug  8 10:40 /home/jenkins

• 啟動(dòng)容器

docker run -d --name jenkins \
-p 8080:8080 -p 50000:50000  \
--privileged=true \
--restart=always \
-v /etc/timezone:/etc/timezone \
-v /etc/localtime:/etc/localtime \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $(which docker):/usr/bin/docker \
-v /home/jenkins:/var/jenkins_home \
-v /usr/bin/mv:/usr/bin/mv \
-v /usr/java/jdk-11.0.4/bin/java:/usr/local/jdk/bin/java \
-v /usr/local/maven:/usr/local/maven \
-v /usr/java/jdk-11.0.4:/usr/local/jdk \
-v /usr/lib64/libltdl.so.7:/usr/lib/x86_64-linux-gnu/libltdl.so.7 \
-u 0 jenkins/jenkins \
--prefix=/jenkins

• 訪問(wèn)jenkins控制臺(tái)
  http://ip:8080/jenkins,提示輸入密碼,因?qū)enkins容器掛載至 /home/jenkins,直接執(zhí)行如下命令:

cat /home/jenkins/secrets/initialAdminPassword

若提示該實(shí)例似乎已離線,參考yum安裝方式該問(wèn)題處理辦法即可.
