Linux（centos7.X）安装Jenkins

it2025-09-01 6

1、新建用户

个人习惯用户新用户去安装新技术插件，如果不喜欢可以省略。

# 新增加用户Jenkins，指定用户组为fordream，指定用户家目录为/home/jenkins useradd -g fordream -d /home/jenkins jenkins # 修改密码 passwd jenkins

2、安装jenkins

1.1 安装仓库

# 如果使用的是root用户，没必要用sudo sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

注意：如果已经导入过key，那么rpm --import命令会报错，无需理会即可。

1.2 安装

# 安装Jenkins，中途需要确认大小，输入y即可。 yum install jenkins

1.3 修改配置

（1）添加本地jdk配置目录

vi /etc/init.d/jenkins 修改 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/lib/jvm/java-11.0/bin/java /usr/lib/jvm/jre-11.0/bin/java /usr/lib/jvm/java-11-openjdk-amd64 /usr/bin/java /usr/local/java/jdk1.8.0_231/bin/java # 此处添加本地jdk安装的java "

**注意：**上面添加的是本地的java运行文件，不是安装地址或目录！

（2）修改Jenkins端口

vi /etc/sysconfig/jenkins 修改 JENKINS_PORT="8088" # 默认为8080，此处我修改为8088

1.4 安装记录

[root@localhost jenkins]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --2020-10-22 08:44:47-- https://pkg.jenkins.io/redhat-stable/jenkins.repo Resolving pkg.jenkins.io (pkg.jenkins.io)... 151.101.230.133, 2a04:4e42:36::645 Connecting to pkg.jenkins.io (pkg.jenkins.io)|151.101.230.133|:443... connected.

3、简单使用

# 启动Jenkins服务 systemctl start jenkins # 查看Jenkins状态 systemctl status jenkins # 停止Jenkins服务 systemctl stop jenkins # 重新启动jenkins服务 systemctl restart jenkins # 如果访问失败，请检查防火墙 systemctl status firewalld # 关闭防火墙 systemctl stop firewalld # 开启防火墙 systemctl start firewalld

4、首次使用

首次访问页面如下：

# 查看初始化密码 cat /var/lib/jenkins/secrets/initialAdminPassword

将密码复制到管理员密码处，然后进行首次登陆。
