1. 简介

Jenkins 是一个 CI/CD 工具。这里CI是指持续集成，CD是指持续交付。Jenkins 也被认为是自动化工具或服务器，它有助于自动化与构建、测试和部署相关的软件开发。

2. 准备条件

系统：centos 8.2
cpu：4
内存：8G
硬盘：40G

3. 安装依赖工具

安装依赖

sudo dnf -y install make autoconf automake cmake perl-CPAN libcurl-devel libtool gcc gcc-c++ glibc-headers zlib-devel git-lfs telnet lrzsz jq expat-devel openssl-devel

安装 Git


cd /tmp
wget --no-check-certificate https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.38.1.tar.gz
tar -xvzf git-2.38.1.tar.gz
cd git-2.38.1/
./configure
make
sudo make install

$ git --version          # 输出 git 版本号，说明安装成功
git version 2.38.1

4. 配置 jenkins 源

官方 Linux 本地安装 Jenkins

echo "192.168.10.90 jenkins_master " | sudo tee -a /etc/hosts

dnf 命令软件更新

sudo dnf update -y
sudo dnf repolist

下载 jenkins 源

sudo dnf install wget -y
sudo wget http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo -O /etc/yum.repos.d/jenkins.repo

运行以下 rpm 命令以导入 Jenkins 包的 GPG 密钥

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

5. 安装 java 17

查询 java 版本

dnf list java* --showduplicates  | sort -r

Available Packages

自 Jenkins 2.357 和 LTS 2.361.1 以来，Jenkins 需要 Java 11 或 17。

java-17-openjdk-devel.x86_64           1:17.0.0.0.35-4.el8             appstream

Java 是 Jenkins 的必备条件之一，所以运行下面的 dnf 命令来安装 java

sudo dnf install -y java-17-openjdk-devel

查看 java 版本

$ java -version
openjdk version "17.0.1" 2021-10-19 LTS
OpenJDK Runtime Environment 21.9 (build 17.0.1+12-LTS)
OpenJDK 64-Bit Server VM 21.9 (build 17.0.1+12-LTS, mixed mode, sharing)

设置Java环境

$ sudo vi /etc/profile.d/java.sh
export JAVA_HOME=$(dirname $(dirname $(readlink $(readlink $(which javac)))))
export PATH=$PATH:$JAVA_HOME/bin
export JRE_HOME=/usr/lib/jvm/jre
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

生效

source /etc/profile.d/java.sh

检查

$ echo $JAVA_HOME

$ env |grep java
