jenkins安装插件问认证问题

【根因】：看报错是由于证书问题导致，jenkins使用了java自带的证书
[root@k8s-master jenkins]# find / -type f -name cacerts
/etc/pki/ca-trust/extracted/java/cacerts
/opt/jdk1.8.0_77/jre/lib/security/cacerts
【方法】：更新java目录下的cacerts证书，重启Jenkins
cd /opt/jdk1.8.0_77/jre/lib/security
mv cacerts /cacerts.bak
cp /etc/pki/ca-trust/extracted/java/cacerts cacerts
systemctl restart jenkins
刷次Jenkins页面，报错解决：
