# 安装jdk1.8（参考上面的安装步骤，或者源码安装java环境）

# 获取jenkins源
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
# 错误: 无法验证 pkg.jenkins.io 的由 “/C=US/O=Let's Encrypt/CN=R3” 颁发的证书:
#   颁发的证书已经过期。
#     要以不安全的方式连接至 pkg.jenkins.io，使用“--no-check-certificate”。

[root@localhost ~]# yum install -y ca-certificates             #安装ca-certificates 解决错误
[root@localhost ~]# yum -y install fontconfig java-11-openjdk  #安装java环境
[root@localhost ~]# yum install -y jenkins                     #直接安装
[root@localhost ~]# java -version                              #查看Java环境
[root@localhost ~]# systemctl start jenkins                    #启动jenkins
[root@localhost ~]# ps -ef |grep jenkins                       #查看jenkins进程
[root@localhost ~]# rpm -ql jenkins                            #可查看jenkins文件放置的目录

#密码放置位置
