Jenkins：安装配置

本机安装jenkins

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-2023.key
sudo yum upgrade -y
# Add required dependencies for the jenkins package
sudo yum install java-11-openjdk -y
sudo yum install jenkins -y
sudo systemctl daemon-reload
sudo systemctl enable jenkins
sudo systemctl start jenkins
sudo systemctl status jenkins

说明

Ubuntu：

jenkins安装目录：/var/lib/jenkins
jenkins日志目录：/var/log/jenkins/jenkins.log
jenkins默认配置：/etc/default/jenkins

Centos7：

jenkins安装目录：/var/lib/jenkins
jenkins日志目录：/var/log/jenkins/jenkins.log
jenkins默认配置：/etc/sysconfig/jenkins

配置root启动（不建议）

# 设置权限
sudo chown -R root:root /var/lib/jenkins/*

# 修改配置:/etc/sysconfig/jenkins
sudo vi /etc/sysconfig/jenkins

# 把以下两个值改为root，默认是$NAME
JENKINS_USER=root
JENKINS_GROUP=root

# 重启Jenkins
sudo systemctl restart jenkins

增加Java虚拟机内存

由于 npm 编译导致jenkins报错502，需要增加Java虚拟机内存，在配置文件中，修改：

# Centos
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Xmx1024m -XX:MaxPermSize=512m"

# 如果是ubuntu
JAVA_ARGS="-Xmx1024m" # 默认是256

配置镜像加速

访问/var/lib/jenkins，编辑hudson.model.UpdateCenter.xml文件

vim hudson.model.UpdateCenter.xml
将url的地址链接https://updates.jenkins.io/update-center.json
修改为https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
