jenkins 1から2へのアップグレード

概要

CentOS7にインストールしたJenkinsをコマンドラインからjenkins2へアップデートする手順

動作環境

CentOS 7.1
Jenkins 1.xxx　あげる前に確認するの忘れました

手順

基本、/usr/lib/jenkins/jenkins.warに最新版のwarファイルを配置して再起動するだ

# cd /usr/lib/jenkins/
# systemctl stop jenkins
# mv jenkins.war jenkins.war.20160611
# wget http://mirrors.jenkins-ci.org/war/latest/jenkins.war
# systemctl start jenkins

/var/log/jenkins/jenkins.log　にエラーでた

サービス自体は起動するものの、ブラウザアクセス不可

復旧手順

/etc/sysconfig/jenkinsに、JENKINS_AJP_PORT="-1" を追記

# cd /etc/sysconfig/
# cp jenkins jenkins.20160611

# vi jenkins

# diff -c jenkins jenkins.20160611
*** jenkins 2016-06-11 21:39:47.321932449 +0900
--- jenkins.20160611    2016-06-11 21:13:03.909234217 +0900
***************
*** 164,168 ****
  # Full option list: java -jar jenkins.war --help
  #
  JENKINS_ARGS=""
-
- JENKINS_AJP_PORT="-1"
--- 164,166 ----

そしてjenkins再起動

# systemctl restart jenkins

無事にブラウザで表示できました
