4. Create a folder in usr/local

Cd/usr/localmkdirjava

5. Put jdk1.8 in the file you just created

Cd/usr/local/java

Decompress after uploading with xftp

Tar-zxvfjdk-8u181-linux-x64.tar.gz

6. Go to the folder you just unzipped

At this point, the environment has been set up, and we have started to build maven and gitlab.

Gitlab building

1. New / etc/yum.repos.d/gitlab-ce.repo

Vim/etc/yum.repos.d/gitlab-ce.repo

Then press the I key to insert the following

[gitlab-ce] name=GitlabCERepositorybaseurl= https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/gpgcheck=0enabled=1

two。

3. Configure external_url

Vim/etc/gitlab/gitlab.rb

Modify the external_url address to: http:// native address: Port number /

Local address view: ifconfig

View the application running by the port number lsof-I: Port number

4.

Gitlab-ctlreconfigure

5.

Gitlab-ctlrestart# starts gitlab-ctlstart | stop | status | other restart# operations

6. Visit

Http:// native address: Port number /

FAQ gitlab502: this is where the port is occupied

After ensuring that the port is not occupied, continue to do it again from 4.

Centeros7 builds maven private server

Download nexus3.x:

Https://www.sonatype.com/download-oss-sonatype

1. Create a nexus file under / usr/local

Cd/usr/localmkdirnexuscdnexus

two。 Upload the nexus package you just downloaded and decompress it

Tar-zxvfnexus-3.18.1-01-unix.tar.gz

3.

Cdnexus-3.18.1-01/bin/ls

4. Start

. / nexusrun&

5. Open remote access port

Firewall-cmd--zone=public--add-port=8081/tcp--permanentfirewall-cmd--reload

Browser access

6. Set Boot self-boot

1. Create a service

Vim/usr/lib/systemd/system/nexus.service

two。 Press I to copy the following

[Unit] Description= nexus service [service] Type=forkingLimitNOFILE=65536# warning processing ExecStart=/usr/local/nexus/nexus-3.7.1-02/bin/nexusstartExecReload=/usr/local/nexus/nexus-3.7.1-02/bin/nexusrestartExecStop=/usr/local/nexus/nexus-3.7.1-02/bin/nexusstopRestart=on-failure [Install] WantedBy=multi-user.target

3. Add service to boot boot

Systemctlenablenexus.service

4. Reload the configuration file

Systemctldaemon-reload

7. The running user is root (edit nexus.rc under nexus bin)

Cd/usr/local/nexus/nexus-3.18.1-01/bin/vimnexus.rc

The content is changed to:

Run_as_user= "root"

8. Modify the jdk version to be used when nexus3 starts

Cd/usr/local/nexus/nexus-3.18.1-01/bin/vimnexus

Press I to add the following

INSTALL4J_JAVA_HOME_OVERRIDE=/usr/local/java/jdk1.8.0_181

Java_home address can be output with echo $JAVA_HOME (provided / etc/profile has export)

9. Modify nexus3 default port

The file is in nexus-xx

Etc/nexus-default.properties

Here has been built, the following is deploy to private server and download from private server to test

1. Create facade and upload it to private server

Create a projects under / usr

Cd/usrmkdirprojects

Unzip the changed zip to projects and enter the directory where pom.xml is located.

Mvndeploy-Dmaven.test.skip=true-U

Has been uploaded successfully

Here we want to put Allow anonymous users to access the server (allowing anonymous users to access the server)

Because the local maven does not have a user configured

You can also use the idea maven command depoly

The id defined in servers in settings.xml is consistent

Add the following image in settings

Central http://repo1.maven.org/maven2central

Finally, the settings file. At this point, the jar package can be released to the private server.

Let's see how to pull it.

Pom.xml of the maven_demo_impl project

After the configuration is completed, you will automatically download jar from the private server.

Jenkins building

1. View the environment version

If there is no java-version#, check the above jdk1.8 installation mvn-v#. If there is no maven installation, check the above git installation.

two。 Install jenkenis

Add Jenkins source:

Sudowget-O/etc/yum.repos.d/jenkins.repo http://jenkins-ci.org/redhat/jenkins.reposudorpm--importhttp://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

3. Installation

Yuminstalljenkins

4. Start

Sudoservicejenkinsstart

5. Visit

Http://ip:8080/#jenkenis defaults to 8080

First password:

Vim / var/lib/jenkins/secrets/initialAdminPassword

Click to install the recommended plug-in (I don't know what to install later)

Modify jenkins port

Vim/etc/sysconfig/jenkins

Modify JENKINS_PORT= "8080" = = > to not occupy the port JENKINS_PORT= "8089" you want to modify

Restart the service

Servicejenkinsrestart

Problem encountered: JDK reinstalled, java address changed

Start jenkins to report error: Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl-xe" for details.

Enter systemctl status jenkins.service as prompted

Solution:

1 > View the environment variables of the current Java

Echo$JAVA_HOME

2 > copy the environment variable address of Java, edit the / etc/init.d/jenkins file, specify the location to add the address, and append the suffix / bin/java

Vim/etc/init.d/jenkins

The point is to configure Jenkins:

1. Configure global jdk maven git

Point Manage Jenkins (system Management)-> Global Tool Configuaration (Global tool configuration)

1.maven configuration: configuring settings.xml addr

two。 Configure the jdk address (which can be obtained with echo $JAVA_HOME)

3.git configuration address can be used (which-a git view)

4.maven configuration address

two。 Create a new task

3. Configuration task

1. Configure source code management the following version is the version number of gitlab

Repository URL: name of warehouse accessed Credentials: access account password or ssh certificate Branch Specifier (blank for 'any'): branch accessed, multiple source code database browsers: select source code database server URL: source code warehouse url Version: source code database server version number

two。 Configuration construction

Cleancompilepackageinstalldeploy-Dmaven.test.skip=true-U# publishes jar

Then apply and complete the configuration!

3. Go to my view (my View)-> find the new project-- > Click build now (build now)

Click the just build in the construction history as shown in the following figure: # 1: build id, console output: you can see the specific output

The following is the input log. You can see the master branch that was previously pulled to the specified project.

The error reported above is a problem with the project, and you can see that the project has been pulled. So make sure the project is correct.

Here are two correct project running examples to automatically send jar to the private server and start the jar project after setting up the gitlab nexus jenkins

Background: the gitlab nexus jenkins has been completed.

1. Release jar to private server after downloading the project from gitlab

Reconfigure the gitlab address:

Configure the maven command:

Cleancompilepackageinstalldeploy-Dmaven.test.skip=true-U

Click build now and look at the console output as follows
