Jenkins–基础–02–安装
1、系统要求
1.1、最低推荐配置
| 内存 | 磁盘空间 | 说明 |
|---|---|---|
| 256MB | 1GB | Docker容器运行jenkins的话推荐10GB磁盘空间 |
1.2、小团队推荐的硬件配置
| 内存 | 磁盘空间 | 说明 |
|---|---|---|
| 1GB+ | 50GB+ | ---- |
1.3、软件配置
- 需要安装jdk11
- 注意: 如果将Jenkins作为Docker 容器运行，这不是必需的
1.4、安装jdk11

1.5、安装maven(建议)
https://blog.csdn.net/zhou920786312/article/details/125832759
1.6、安装git(建议)
yum -y install git
git version
2、Docker安装Jenkins(这是我部署的)
2.1、创建目录
# 创建目录
mkdir -p /home/jenkins_home
# 授权
chmod -R 777 /home/jenkins_home
# 给docker.sock添加读写权限
chmod a+rw /var/run/docker.sock
2.2、脚本
mkdir -p /root/shell
vi jenkins.sh
内容
docker run \
-u root \
-di \
--name=jenkins \
-p 8080:8080 \
-p 50000:50000 \
-v /home/jenkins_home:/var/jenkins_home \
-v /usr/java/jdk-11:/usr/java/jdk-11 \
-v /usr/local/maven/apache-maven-3.3.9:/usr/local/maven/apache-maven-3.3.9 \
-v $(which docker):/usr/bin/docker \
-v /var/run/docker.sock:/var/run/docker.sock \
jenkins/jenkins:lts
2.2.1、/var/run/docker.sock:/var/run/docker.sock(可选)
- 表示Docker守护程序通过其监听的基于Unix的套接字。
- 该映射允许 jenkinsci/blueocean 容器与Docker守护进程通信，如果 jenkinsci/blueocean 容器需要实例化其他Docker容器，则该守护进程是必需的。
2.2.2、/home/jenkins_home:/var/jenkins_home
持久化Jenkins的一些配置信息
2.2.3、/usr/java/jdk-11:/usr/java/jdk-11 \
- 是把linux下的jdk和容器内的关联
- 配置Jenkins时使用
2.2.4、/usr/local/maven/apache-maven-3.3.9:/usr/local/maven/apache-maven-3.3.9
- 是把linux下的maven和容器内的关联
- 配置Jenkins时使用
2.3、授权和执行
chmod +x /root/shell/jenkins.sh
/root/shell/jenkins.sh
2.4、安装成功后的显示页面
http://192.168.187.171:8080
3、war安装Jenkins
3.1、下载
http://mirrors.jenkins.io/war-stable/latest/jenkins.war
3.2、执行
java -jar /root/jenkins/jenkins.war
启动日志
[[email protected] jenkins]# java -jar /root/jenkins/jenkins.war
