安裝
oracle和openjdk選擇其一
安裝jdk
oracleJdk官網: https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
安裝oracle JDK
# 自行下載
rpm -ivh jdk-8u251-linux-x64.rpm
# tar包 安裝方法
tar xf jdk-8u251-linux-x64.tar.gz -C /usr/local/
mv /usr/local/jdk-8u251/ /usr/local/jdk
vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
source /etc/profile
# 驗證安裝
[root@node2 ~]# java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)安裝openjdk
dnf install java-1.8.0-openjdk java-1.8.0-openjdk-devel
安裝maven
清華大學maven源:https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/
wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz tar xf apache-maven-3.6.3-bin.tar.gz -C /usr/local/ ln -s /usr/local/apache-maven-3.6.3/ /usr/local/maven echo 'export PATH="/usr/local/maven/bin:$PATH"' >> /etc/profile source /etc/profile # 驗證安裝 [root@node2 ~]# mvn -v Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven home: /usr/local/maven Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: /usr/java/jdk1.8.0_251-amd64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "4.18.0-193.6.3.el8_2.x86_64", arch: "amd64", family: "unix"
安裝jenkins
下載地址:https://www.jenkins.io/zh/download/
rpm -ivh jenkins-2.235.1-1.1.noarch.rpm
修改配置檔案
主配置檔案主要修改執行使用者即可:/etc/sysconfig/jenkins
[root@node2 ~]# vim /etc/sysconfig/jenkin JENKINS_USER="root"
手動安裝的jdk要在jenkins配置檔案中指一下:/etc/init.d/jenkins
vim /etc/init.d/jenkins candidates=" /etc/alternatives/java /usr/lib/jvm/java-1.8.0/bin/java /usr/lib/jvm/jre-1.8.0/bin/java /usr/lib/jvm/java-1.7.0/bin/java /usr/lib/jvm/jre-1.7.0/bin/java /usr/bin/java /usr/local/jdk/bin/java # 新新增jdk路徑 "
修改外掛庫源需要先啟動下jenkins才會生成配置檔案
[root@node2 ~]# cat /var/lib/jenkins/hudson.model.UpdateCenter.xml
<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<--! <url>https://updates.jenkins.io/update-center.json</url> -->
<url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url>
</site>
</sites>
修改升級地址
sed -i 's@http://updates.jenkins-ci.org/download/@https://mirrors.tuna.tsinghua.edu.cn/jenkins/@g' /var/lib/jenkins/updates/default.json sed -i 's@http://www.google.com/@http://www.baidu.com/@g' /var/lib/jenkins/updates/default.json
啟動並設定開機啟動
[root@node2 ~]# systemctl restart jenkins && systemctl enable jenkins
