Jenkins installation and upgrade
Background
Recently, I have been working on jenkins continuous integration. I am going to write a blog post and record it. Please see the previous blog post about jenkins. This article mainly introduces jenkins installation and upgrade, the operation is still very simple. Installation environment: Centos6.8 X64.
Installation introduction
Jenkins can be started through the java-jar jenkins.war command, or the war package of jenkins can be started under tomcat, which is called method one and method two, respectively.
Method one environment prepares yum install java-1.8.0-openjdk* wget-y wyum-y install zlib-devel openssl-devel perl cpio expat-devel gettext-devel autoconf curl-devel expect to install maven
Download the apache-maven-3.3.3-bin.tar.gz package at http://maven.apache.org/download.cgi
Decompression
Tar-zxvf apache-maven-3.3.3-bin.tar.gz-C / data/service
Establish a soft link
Ln-sv apache-maven-3.3.3 maven
Configure environment variables
Vim / etc/profile
M3_HOME=/data/service/maven
PATH=$ {M3_HOME} / bin:$ {PATH}
Export PATH
Install wget-O / etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.reporpm-- import https://jenkins-ci.org/redhat/jenkins-ci.org.key yum install jenkins-y

Method 2 Environmental preparation
Refer to method 1, you also need to install tomcat, this test environment installed the Apache Tomcat/9.0.0.M19 version, the tomcat installation directory is / home/tomcat.
Install maven
Reference method 1
Installation
Download the jenkins.war package at wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war
Put the package in the webapps directory of tomcat, and then start tomcat.

Upgrade
After Jenkins is installed, the upgrade is relatively simple. If it is installed in yum or apt-get mode, you can upgrade it directly through the relevant commands. Because the server is abroad, so the online installation will be slow, so we will upgrade directly through the war package.
Upgrade steps:
1. Download the latest version of the war package of jenkins. Generally, you can download it through these links:
Http://mirror.xmission.com/jenkins/war-stable/
Http://ftp.yz.yamagata-u.ac.jp/pub/misc/jenkins/war-stable/
Https://updates.jenkins-ci.org/download/war/
Https://mirrors.tuna.tsinghua.edu.cn/jenkins/
2. Stop the jenkins service and back up jenkins's original war package and jenkins home directory data
3. Upload the latest war package to the jenkins server and start jenkins
