測試環境
- Linux系統 Centos 7
安裝步驟：
1、安裝jdk
我安裝的是jdk8，此處就不多說了，自己百度哈，很簡單
2、安裝jenkins
首先依次執行如下三個命令：
2.1、導入鏡像：
[root@centos7 ~]# sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
--2019-12-24 17:59:44-- https://pkg.jenkins.io/redhat-stable/jenkins.repo

Connecting to pkg.jenkins.io (pkg.jenkins.io)|52.202.51.185|:443... connected.

2019-12-24 18:00:47 (17.4 MB/s) - ‘/etc/yum.repos.d/jenkins.repo’ saved [85/85]
2.2、導入公鑰
[root@centos7 ~]# sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
2.3、安裝jenkins：
[root@centos7 ~]# yum install jenkins

Complete!
2.4、修改配置文件
[root@centos7 ~]# vi /etc/sysconfig/jenkins
修改這部分：
## Default: 8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8091"
## Type: string
## Default: ""
## ServiceRestart: jenkins
2.5、啟動jenkins
[root@centos7 ~]# systemctl start jenkins
Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.
2.6、查看jenkins的啟動狀態
[root@centos7 ~]# systemctl status jenkins
● jenkins.service - LSB: Jenkins Automation Server
Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)
Active: failed (Result: exit-code) since Tue 2019-12-24 18:12:05 CST; 11s ago
Docs: man:systemd-sysv-generator(8)
Process: 23175 ExecStart=/etc/rc.d/init.d/jenkins start (code=exited, status=1/FAILURE)
Dec 24 18:12:05 centos7 systemd[1]: Starting LSB: Jenkins Automation Server...

Dec 24 18:12:05 centos7 jenkins[23175]: Starting Jenkins bash: /usr/bin/java: Is a directory
Dec 24 18:12:05 centos7 systemd[1]: jenkins.service: control process exited, code=exited status=1
Dec 24 18:12:05 centos7 jenkins[23175]: [FAILED]
Dec 24 18:12:05 centos7 systemd[1]: Failed to start LSB: Jenkins Automation Server.
Dec 24 18:12:05 centos7 systemd[1]: Unit jenkins.service entered failed state.
Dec 24 18:12:05 centos7 systemd[1]: jenkins.service failed.
出現這種情況的解決辦法是：
修改 jenkins 的配置文件中使用的 jdk 路徑
[root@centos7 ~]# echo $JAVA_HOME
/usr/java/jdk1.8.0_191
[root@centos7 ~]# vi /etc/init.d/jenkins
注意：這里echo $JAVA_HOME 出來的路徑，后面一定跟啟動路徑（/bin/java）
2.7、重啟並查看 jenkins 狀態
systemctl daemon-reload
systemctl restart jenkins
我的 jenkins 啟動后是這樣子的：
[root@centos7 docker]# systemctl daemon-reload
[root@centos7 docker]# systemctl restart jenkins
[root@centos7 docker]# systemctl status jenkins
● jenkins.service - LSB: Jenkins Automation Server
Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)
Active: active (running) since Tue 2019-12-24 18:16:08 CST; 12s ago
Docs: man:systemd-sysv-generator(8)
Process: 23787 ExecStart=/etc/rc.d/init.d/jenkins start (code=exited, status=0/SUCCESS)
CGroup: /system.slice/jenkins.service

Dec 24 18:16:08 centos7 systemd[1]: Started LSB: Jenkins Automation Server.
Dec 24 18:16:08 centos7 jenkins[23787]: Starting Jenkins [ OK ]
[root@centos7 ~]# lsof -i:8091
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 23832 jenkins 160u IPv4 11605726 0t0 TCP *:jamlink (LISTEN)
好了，此時已經表示 Jenkins 順利安裝並啟動成功了！
2.8、訪問瀏覽器: http://localhost:8091/ 出現如下提示：
Please wait while Jenkins is getting ready to work...
解決辦法：
進入jenkins的工作目錄（/var/lib/jenkins/），打開 hudson.model.UpdateCenter.xml
把 http://updates.jenkins-ci.org/update-center.json 改成如下三個地址之一均可：
# 修改更新地址（到其中一種即可）：
http://mirror.xmission.com/jenkins/updates/update-center.json
http://updates.jenkins.io/update-center.json
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
http://mirror.esuni.jp/jenkins/updates/update-center.json
然后重啟並查看 jenkins 狀態：
[root@centos7 ~]# vi hudson.model.UpdateCenter.xml
[root@centos7 ~]# systemctl daemon-reload
[root@centos7 ~]# systemctl restart jenkins
[root@centos7 ~]# systemctl status jenkins
查看密碼：
cat /var/lib/jenkins/secrets/initialAdminPassword
然后直接選推薦安裝的插件，或者直接下一步就完事兒了！
2.9、設置jenkin語言為中文
需要的話，還可以設置語言為中文
- 1、系統管理->插件管理->可用插件：安裝Locale Plugin插件（https://wiki.jenkins.io/display/JENKINS/Locale+Plugin），重啟；
- 2、如果沒有搜索到這個插件，就直接官網（https://github.com/jenkinsci/locale-plugin或者https://updates.jenkins.io/download/plugins/locale/）下載安裝：
系統管理->插件管理->高級->上傳插件，安裝重啟； - 3、系統管理->系統管理->locale language->輸入zh_CN
最新版本的jenkins，即使設置了zh_CN也有可能是中英文混搭風， 因為最新版本沒有針對所有內容都翻譯成中文。
