测试环境

Linux系统 Centos 7

安装步骤：

1、安装jdk

我安装的是jdk8，此处就不多说了，自己百度哈，很简单

2、安装jenkins

首先依次执行如下三个命令：

2.1、导入镜像：

[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

Resolving pkg.jenkins.io (pkg.jenkins.io)... 52.202.51.185

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、导入公钥

[root@centos7 ~]# sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

2.3、安装jenkins：

[root@centos7 ~]# yum install jenkins

Loaded plugins: fastestmirror

Complete!

2.4、修改配置文件

[root@centos7 ~]# vi /etc/sysconfig/jenkins

修改这部分：

## Default: 8080

## ServiceRestart: jenkins

#

# Port Jenkins is listening on.

# Set to -1 to disable

#

JENKINS_PORT="8091"

## Type: string

## Default: ""

## ServiceRestart: jenkins

2.5、启动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的启动状态

[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 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.

出现这种情况的解决办法是：

修改 jenkins 的配置文件中使用的 jdk 路径

[root@centos7 ~]# echo $JAVA_HOME

/usr/java/jdk1.8.0_191

[root@centos7 ~]# vi /etc/init.d/jenkins

注意：这里echo $JAVA_HOME 出来的路径，后面一定跟启动路径(/bin/java)

2.7、重启并查看 jenkins 状态

systemctl daemon-reload

systemctl restart jenkins

我的 jenkins 启动后是这样子的：

[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)

好了，此时已经表示 Jenkins 顺利安装并启动成功了！

Please wait while Jenkins is getting ready to work...

解决办法：

进入jenkins的工作目录(/var/lib/jenkins/)，打开 hudson.model.UpdateCenter.xml

把 http://updates.jenkins-ci.org/update-center.json 改成如下三个地址之一均可：

# 修改更新地址(到其中一种即可)：

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

然后重启并查看 jenkins 状态：

[root@centos7 ~]# vi hudson.model.UpdateCenter.xml

[root@centos7 ~]# systemctl daemon-reload

[root@centos7 ~]# systemctl restart jenkins

[root@centos7 ~]# systemctl status jenkins

查看密码：

cat /var/lib/jenkins/secrets/initialAdminPassword

然后直接选推荐安装的插件，或者直接下一步就完事儿了！

2.9、设置jenkin语言为中文

需要的话，还可以设置语言为中文

3、系统管理->系统管理->locale language->输入zh_CN

最新版本的jenkins，即使设置了zh_CN也有可能是中英文混搭风， 因为最新版本没有针对所有内容都翻译成中文。

卸载

[root@centos7 ~]# rpm -e jenkins

warning: /etc/sysconfig/jenkins saved as /etc/sysconfig/jenkins.rpmsave

warning: /etc/init.d/jenkins saved as /etc/init.d/jenkins.rpmsave

[root@centos7 ~]# systemctl stop jenkins

[root@centos7 ~]# rpm -ql jenkins

package jenkins is not installed

[root@centos7 ~]# find / -iname jenkins | xargs -n 1000 rm -rf
