1. 安裝JDK【java8】

1.1. 軟件安裝

[yun@mini05 software]# pwd

/app/software

[yun@mini05 software]# tar xf jdk1.8.0_112.tar.gz

[yun@mini05 software]# ll

total 201392

drwxr-xr-x 8 10 143 4096 Dec 20 13:27 jdk1.8.0_112

-rw-r--r-- 1 root root 189815615 Mar 12 16:47 jdk1.8.0_112.tar.gz

[yun@mini05 software]# mv jdk1.8.0_112/ /app/

[yun@mini05 software]# cd /app/

[yun@mini05 app]# ll

total 8

drwxr-xr-x 8 10 143 4096 Dec 20 13:27 jdk1.8.0_112

[yun@mini05 app]# ln -s jdk1.8.0_112/ jdk

[yun@mini05 app]# ll

total 8

lrwxrwxrwx 1 root root 13 May 16 23:19 jdk -> jdk1.8.0_112/

drwxr-xr-x 8 10 143 4096 Dec 20 13:27 jdk1.8.0_112

1.2. 環境變量

[root@mini05 ~]$ pwd

/app

[root@mini05 ~]$ ll -d jdk*

lrwxrwxrwx 1 yun yun 11 Mar 15 14:58 jdk -> jdk1.8.0_112

drwxr-xr-x 8 yun yun 4096 Dec 20 13:27 jdk1.8.0_112

[root@mini05 profile.d]$ pwd

/etc/profile.d

[root@mini05 profile.d]$ cat jdk.sh # java環境變量

export JAVA_HOME=/app/jdk

export JRE_HOME=/app/jdk/jre

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH

export PATH=$JAVA_HOME/bin:$PATH

[root@mini05 profile.d]# source /etc/profile

[root@mini05 profile.d]$ java -version

java version "1.8.0_112"

Java(TM) SE Runtime Environment (build 1.8.0_112-b15)

Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

2. 安裝jenkins

2.1. 軟件安裝

[root@mini05 ~]# cd /etc/yum.repos.d/

[root@mini05 yum.repos.d]# wget http://pkg.jenkins.io/redhat/jenkins.repo

[root@mini05 yum.repos.d]# rpm --import http://pkg.jenkins.io/redhat/jenkins.io.key

[root@mini05 yum.repos.d]# yum install -y jenkins

2.2. 啟動jenkins

[root@mini05 ~]# 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.

[root@mini05 ~]# systemctl status jenkins.service # 查看Jenkins狀態【因為有問題】

● jenkins.service - LSB: Jenkins Automation Server

Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)

Active: failed (Result: exit-code) since Sun 2018-10-07 10:28:30 CST; 5s ago

Docs: man:systemd-sysv-generator(8)

查看jenkins狀態

解決方法修改 jenkins 啟動腳本

[root@mini05 ~]# vim /etc/rc.d/init.d/jenkins

# 添加了 /app/jdk/bin/java 這樣信息

candidates="

/etc/alternatives/java

/usr/lib/jvm/java-1.8.0/bin/java

/usr/lib/jvm/jre-1.8.0/bin/java

再次報錯修改

1 [root@mini05 ~]# systemctl start jenkins

2 Warning: jenkins.service changed on disk. Run 'systemctl daemon-reload' to reload units.

3 [root@mini05 ~]# systemctl daemon-reload # 執行該命令

啟動jenkins

重啟Jenkins服務

[root@mini05 ~]# systemctl stop jenkins

[root@mini05 ~]# systemctl start jenkins

3.首次訪問Jenkins

http://10.0.0.15

根據頁面提示找密碼，輸入即可

參考博文：安裝Jenkins時不能聯網安裝插件問題解決

說明：在網上找了很多文章去解決該離線問題，但是最後都沒有解決。所以只能進入頁面後再手動安裝常用插件。
