Install the Docker
- Download the repO of Docker-CE
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
Copy the code- Install dependencies
Yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm
Copy the codePs: Containerd version is too late to install Containerd docker
- Install the docker – ce
yum install docker-ce
Copy the code- Start the docker
systemctl start docker
Copy the code- Setting domestic source
"registry-mirrors": [
"https://1nj0zren.mirror.aliyuncs.com"."https://docker.mirrors.ustc.edu.cn".
"http://f1361db2.m.daocloud.io"."https://registry.docker-cn.com"]
Copy the code- restart
sudo systemctl daemon-reload
sudo systemctl restart docker
Copy the codeInstall the Portainer
Introduction of a docker visual interface Portainer, you can easily view the start delete stop container, also can manage images
docker pull portainer/portainer
docker run -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -d portainer/portainer
Copy the code
Install Jenkins
docker pull jenkinsci/blueocean
docker run -d --name jenkins -p 9001:8080 -p 50000:50000 --env PATH = / usr/share/maven/bin: / usr/local/sbin, / usr/local/bin: / usr/sbin, / usr/bin, / sbin, / bin: / usr/lib/JVM/Java - 1.8 - its/jre / bin: / usr/lib/JVM/Java - 1.8 - its/bin - v/var/run/docker. The sock: / var/run/docker. The sock - v /dockerworkspace/jenkins:/var/jenkins_home -v /opt/maven:/usr/share/maven -v /etc/localtime:/etc/localtime jenkinsci/blueocean
Copy the codePs:
-
Jenkins plug-in mirror address https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json, tsinghua university
-
May appear java.net.UnknownHostException, troubled me for a long time, baidu search out answers are unreliable. I read an article that said it might be the firewall. Turn off the firewall and restart immediately. The pit!
Systemctl Status firewalld.service Displays the firewall status
Systemctl stop firewalld. Service Run the command to stop running the firewall
Systemctl disable firewalld.service Disables automatic firewall startup
Copy the codeFirewall start and start commands:
A. start:
systemctl start firewalld.service
Copy the codeB. The firewall starts with the system:
systemctl enable firewalld.service
Copy the code- Error:
Touch: cannot touch '/var/jenkins_home/copy_reference_file.log' : Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
Copy the codeYou need to change the directory permissions, because when mapping local data volumes, the owner of the /home/docker-Jenkins directory is user root, and the UID of Jenkins user in the container is 1000
sudo chown -R 1000:1000 /dockerworkspace/jenkins
Copy the code- Port 8080 is the Jenkins port, and port 5000 is the master and slave communication port
- Jenkin calls Docker without permission
chmod 666 /var/run/docker.sock
Copy the code- clock of the subversion server appears to be out of sync. This can result in inconsistent check out behavior. svn Add @HEAD to the end of the URL
Install Maven
- download
Wget HTTP: / / http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
Copy the code- Unpack the
tar xf /tmp/apache-maven-*.tar.gz -C /opt
Copy the code- Set the environment variable (Jenkins of DockerHub is used here, so it can be omitted)
nano /etc/profile.d/maven.sh
Copy the codePaste the following code:
Export JAVA_HOME = / usr/lib/JVM/Java - 1.8 - its
export MAVEN_HOME=/usr/opt/maven
export PATH=${MAVEN_HOME}/bin:${PATH}
Copy the codeFor better control of Maven versions and updates, we will create a symbolic link, Maven, that points to the Maven installation directory:
Ln -s/opt/apache maven - 3.6.3 / opt/maven
Copy the codeMake the script executable by running the following chmod command
chmod +x /etc/profile.d/maven.sh
Copy the codeLoad environment variables using the following source command:
source /etc/profile.d/maven.sh
Copy the code-
Build the Maven multi-module project
Configure a Maven-style project and then configure it
The root POM points to the top-level pom.xml
mvn clean install -pl ETECSA-SERVER/ETECSA-SERVER-EUREKA -am -amd -Dmaven.test.skip=true
Copy the codeThis way, the Etecsa-server-Eureka jar is built separately, and the dependencies are built without having to put them into maven’s repository ahead of time
According to the information:
| parameter | The full name | paraphrase | instructions |
|---|---|---|---|
| -pl | –projects | Build specified reactor projects instead of all projects | Options can be followed by {groupId}:{artifactId} or the relative path of the selected module (multiple modules separated by commas) |
| -am | –also-make | If project list is specified, also build projects required by the list | Represents the module on which the selected module depends |
| – amd | –also-make-dependents | If project list is specified, also build projects that depend on projects on the list | Represents simultaneous processing of modules that depend on the selected module |
| -N | –Non-recursive | Build projects without recursive | Represents a non-recursive submodule |
| -rf | –resume-from | Resume reactor from specified project | Indicates that processing continues from the specified module |
Ps:
Permission denied exceptions
Solutions:
Add Jenkins user to docker group and restart Jenkins service
sudo gpasswd -a jenkins docker
sudo systemctl jenkins restart
