centos安装jenkins遇到的问题

官方网站https://pkg.jenkins.io/redhat-stable/，按着步骤来

第一步

1	sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

不成功，提示错误是

Resolving pkg.jenkins.io (pkg.jenkins.io)... 151.101.74.133, 2a04:4e42:1a::645
Connecting to pkg.jenkins.io (pkg.jenkins.io)|151.101.74.133|:443... connected.
ERROR: cannot verify pkg.jenkins.io's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’:
  Issued certificate has expired.
To connect to pkg.jenkins.io insecurely, use `--no-check-certificate'.

加上--no-check-certificate再试

3

sudo wget --no-check-certificate -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
// jenkins.repo会添加到/etc/yum.repos.d/中
cat /etc/yum.repos.d/jenkins.repo

第二步

1	sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

不成功，提示错误

安装java

java已安装，跳过

1 2	yum install epel-release yum install java-1.8.0-openjdk-devel

安装jenkins

1	yum install jenkins

不成功，提示
