1. Build the environment needed by Jenkins

two。 Choose how to install Jenkins

The process is as follows:

Environment (git, maven, java)

Jdk installation: download the jdk package in advance before uploading / usr/local

Rpm-qa | grep openjdk

Rpm-e-- nodeps deletes the jdk package that comes with it

(wget-O / usr/local/jdk-8u191-linux-x64.tar.gz http://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jdk-8u231-linux-x64.tar.gz) (wget download does not accept the agreement by default, so it is not adopted)

Cd / usr/local

Tar-xvf jdk-8u231-linux-x64.tar.gz

Vi / etc/profile

Export JAVA_HOME= / usr/local/jdk1.8.0_231

Export CLASSPATH=.:$ {JAVA_HOME} / jre/lib/rt.jar:$ {JAVA_HOME} / lib/dt.jar:$ {JAVA_HOME} / lib/tools.jar

Export PATH=$PATH:$ {JAVA_HOME} / bin

Source / etc/profile

Maven installation: (mvn-v view version)

Wget-O / usr/local/apache-maven-3.6.1-bin.tar.gz http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

Cd / usr/local

Tar-zxvf apache-maven-3.6.1-bin.tar.gz

Vi / etc/profile

Export MAVEN_HOME=/usr/local/apache-maven-3.6.1

Export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin

Source / etc/profile

Git installation

Yum install-y git (git-- version) View version

Jenkins installation (choose yum installation)

Cd / etc/yum.repos.d/

Wget http://pkg.jenkins.io/redhat/jenkins.repo

Rpm-- import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

Yum install-y jenkins

Systemctl start jenkins

Finally, open the browser and enter ip:8080 to install it.

Start the jenkins error message:

Starting Jenkins bash: / usr/bin/java: No such file or directory

Solution:

Vim / etc/init.d/jenkins

Join here

Candidates= "

/ setup/tools/jdk1.8.0_144/bin/java # here is the java path to join

Vim / etc/sysconfig/jenkins

Do

[- x "$JENKINS_JAVA_CMD"] & & break

JENKINS_JAVA_CMD= "$candidate" # here is $candidate

Done

Systemctl daemon-reload

Systemctl start Jenkins
