jenkins升級

1丶查看war包所在的目錄

#rpm -ql jenkins
/etc/init.d/jenkins                //jenkins的啓動文件
/etc/logrotate.d/jenkins           //日誌切割
/etc/sysconfig/jenkins             //jenkins的配置文件
/usr/lib/jenkins                   
/usr/lib/jenkins/jenkins.war       //jenkins的程序war包
/usr/sbin/rcjenkins                //jenkins的爲二進制文件
/var/cache/jenkins                 //jenkins的程序文件，運行程序解壓出來的
/var/lib/jenkins                   //jenkins的主目錄
/var/log/jenkins                   //jenkins的日誌文件

2丶下載最新版本的jenkins的war包

test -d /tools || mkdir /tools 
cd /tools 
wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/war/2.125/jenkins.war

3丶中止jenkins服務

systemctl stop jenkins

4丶備份原來的war包,並拷貝最新版本war包到/usr/lib/jenkins目錄下

cd /usr/lib/jenkins/
mv jenkins.war jenkins-2.89.4.war.bak
mv /tools/jenkins.war .

5丶啓動jenkins

systemctl start jenkins 
ss -anltup | grep 8080
