二、jenkins的安装部署

1、下载jenkins

[root@jenkins ~]# wget https://mirrors.aliyun.com/jenkins/redhat-stable/jenkins-2.452.2-1.1.noarch.rpm

2、安装jenkins

[root@jenkins ~]# yum install -y fontconfig jdk-17.0.10_linux-x64_bin.rpm  jenkins-2.452.2-1.1.noarch.rpm

[root@jenkins ~]# java -version

</sites>
[root@jenkins jenkins]# 
[root@jenkins jenkins]# systemctl restart jenkins

4、初始化jenkins

[root@jenkins ~]# sed -i 's/https:\/\/updates.jenkins.io\/download/http:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' /var/lib/jenkins/updates/default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' /var/lib/jenkins/updates/default.json
