| - | ====== Jenkins Topics ====== | + | <typo fs:xx-large; fw:bold>Jenkins Topics</typo> |
| + | ====== Installation & Configuration ====== | ||
| + | ===== Prerequisites ===== | ||
| + | * OpenJDK 8: ''yum install java-1.8.0-openjdk-devel'' | ||
| + | * Maven: [[#maven_installation|see installation instructions below]] | ||
| + | |||
| + | ===== Jenkins Installation ===== | ||
| + | Pull the Jenkins repository file and import its GPG key: | ||
| + | <code> | ||
| + | wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo | ||
| + | rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key | ||
| + | </code> | ||
| + | ... then, do a ''yum update'' and ''yum install jenkins'' \\ | ||
| + | If the ''jenkins'' login isn't locked down off-server: | ||
| + | * Enable login for Jenkins with ''usermod -s /bin/bash jenkins'' | ||
| + | * Log in as ''jenkins'' and create SSH key with: ''ssh-keygen -t rsa'' | ||
| + | Otherwise: | ||
| + | * Create SSH key for ''jenkins'' from root: ''ssh-keygen -f id_rsa -C "jenkins@bluejay"'' | ||
| + | Open firewall for Jenkins:<code> | ||
| + | firewall-cmd --permanent --zone=public --add-port=8080/tcp | ||
| + | firewall-cmd --reload | ||
| + | </code> | ||
| + | Remember to ''systemctl enable jenkins'' and ''systemctl start jenkins'' \\ | ||
| + | Log in (default login is ''admin'' with password ''admin'') and change password, add user(s) \\ | ||
| + | |||
| + | ===== Maven Installation ===== | ||
| + | Get latest maven archive, example:<code>wget http://www-eu.apache.org/dist/maven/maven-3/3.6.0/binaries/apache-maven-3.6.0-bin.tar.gz</code> | ||
| + | Extract to suitable location and sym-link to it (''/usr/maven'' or ''/opt/maven'') \\ | ||
| + | Set environment variables in ''/etc/profile.d/maven.sh'':<code> | ||
| + | export M3_HOME=/usr/maven | ||
| + | export M2_HOME=${M3_HOME} | ||
| + | export PATH=${M3_HOME}/bin:${PATH} | ||
| + | </code> | ||
| + | ... perform a ''source /etc/profile.d/maven.sh'' to get these in current shell. | ||
| + | |||
| + | |||
| + | ===== Configuration ===== | ||
| + | |||
| + | ==== Environment Variables ==== | ||
| + | Some environment variables may need to be set at the global level, which can be configured under the "Manage Jenkins" section: | ||
| + | * PATH | ||
| + | * JAVA_HOME | ||
| + | * M3_HOME | ||
| + | |||
| + | ===== Trivia ===== | ||

| You will need to explicitly install a Java runtime environment, because Oracle's Java RPMs are incorrect and fail to register as providing a java dependency. Thus, adding an explicit dependency requirement on Java would force installation of the OpenJDK JVM. \\ | You will need to explicitly install a Java runtime environment, because Oracle's Java RPMs are incorrect and fail to register as providing a java dependency.
