# 105

which git
/usr/bin/git

which java
/usr/bin/java

which mvn
/opt/apache-maven-3.8.7/bin/mvn

which jenkins
/usr/bin/jenkins

安装 jdk

安装 git

安装 maven

修改 /opt/apache-maven-3.8.7/conf/settings.xml

安装 nodejs

url:
https://nodejs.org/en/download
https://nodejs.org/en/download/releases
https://nodejs.org/download/release/v16.19.1/

一开始安装的18版本的nodejs，与我自己的centos不匹配，改装的16版本

tar -xf node-v16.19.1-linux-x64.tar.gz 
mv node-v16.19.1-linux-x64 /usr/local/nodejs

vim /etc/profile

#node
export NODE_HOME=/usr/local/nodejs
export PATH=$NODE_HOME/bin:$PATH
export NODE_PATH=$NODE_HOME/lib/node_modules

source /etc/profile
node -v
npm -v

npm install -g yarn
yarn --version


yarn config get registry
yarn config set registry https://registry.npm.taobao.org

安装 Jenkins

https://www.jenkins.io/

wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/jenkins-2.346.3-1.1.noarch.rpm --no-check-certificate
yum -y install jenkins-2.346.3-1.1.noarch.rpm

 

修改用户

默认 Jenkins Jenkins

vim /usr/lib/systemd/system/jenkins.service

 

 

 修改端口号

默认8080

vim /usr/lib/systemd/system/jenkins.service

 

上述方案若未生效 可使用下面的方案直接指定脚本执行时的port

vim /usr/bin/jenkins

 

工作目录

jenkins默认工作目录为~/.jenkins，可以通过配置JENKINS_HOME环境变量来指定。

比如在 /etc/profile 中添加 export JENKINS_HOME="/data/jenkins/"

 vim /etc/profile

 export JENKINS_HOME=/run/app/jenkins

source /etc/profile

 

jenkins服务中的配置 

/usr/lib/systemd/system/jenkins.service
