CenterOS7 installation and configuration environment jdk1.8 tutorial

CenterOS7 installation and configuration environment jdk1.8 tutorial

1. Uninstall the JDK that comes with centeros first

rpm-qa|grepopenjdk

The built-in openjdk found out

2. Delete

rpm -e --nodeps

3. Query again

rpm-qa|grepjdk

4. Create a folder in usr/local

cd /usr/local
mkdirjava

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

cd /usr/local/java

Upload with xftp and then decompress

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

6. Enter the folder you just unzipped

cdjdk1.8.0_181/pwd# (This step records the path of jdk1.8, which will be used to configure the environment later)

7. Configure the environment

vim/etc/profile

Press i to insert the following path

exportJAVA_HOME=/usr/local/java/jdk1.8.0_181exportCLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexportPATH=$PATH:$JAVA_HOME/bin

After pressing Esc: wq exits

source/etc/profile

8. Check if it is successful

java-version

Maven environment configuration

1. Create a maven folder under /usr/local

cd /usr/localmkdirmaven

2. Enter the newly created folder

cdmaven

Upload apache-maven-3.5.4-bin.zip

3. Unzip

unzipapache-maven-3.5.4-bin.zip

4. Enter the unzipped folder

cdapache-maven-3.5.4/pwd#(Record this path, it will be used in the configuration environment later)

5. Configure the environment

vim/etc/profile

Press i to insert the following

exportMAVEN_HOME=/usr/local/maven/apache-maven-3.5.4exportPATH=$PATH:$MAVEN_HOME/bin

After pressing Esc: wq save

source/etc/profile

6. Check if it is successful

mvn-v

Install git on centeros7

yuminstallgit

Just go down y

Check if it is successful

git --version

View the git command address

which-agit

Now the environment has been set up, and we can start to build Maven private server and gitlab.

Gitlab setup

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

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

Then press the i key to insert the following content

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

2.

sudoyummakecachesudoyuminstallgitlab-ce#(install the latest) or sudoyuminstallgitlab-ce-12.0.4#(specify the version number)

3. Configure external_url

vim/etc/gitlab/gitlab.rb

Modify the external_url address to: http://本機地址:端口號/

Check the local address: ifconfig

Check the application running on the port number lsof -i:port number

4.

gitlab-ctlreconfigure

5.

gitlab-ctlrestart#Startgitlab-ctlstart|stop|status|restart#Other operations

6. Access

http://localhost address:port number/

FAQ gitlab502 : This port is occupied

Make sure the port is not occupied and continue from 4.

centeros7 builds maven private server

Download nexus3.x:

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

1. Create a nexus file in /usr/local

cd /usr/localmkdirnexuscdnexus

2. Upload the nexus compressed package 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 the remote access port

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

Browser access

6. Set the startup to start automatically

1. Create a service

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

2. Press i to copy the following

[Unit]Description=nexusservice[Service]Type=forkingLimitNOFILE=65536 #Warning handlingExecStart=/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 the service to startup

systemctlenablenexus.service

4. Reload the configuration file

systemctldaemon-reload

7. Run as 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

The java_home address can be output using echo $JAVA_HOME (assuming that /etc/profile is exported)

9. Modify the default port of nexus3

Files in nexus-xx

etc/nexus-default.properties

It has been built here. The following is to deploy to the private server and download from the private server for testing

1. Create a facade and upload it to a private server

Create projects under /usr

cd /usr/mkdirprojects

Unzip the zip file to the project directory and enter the directory where pom.xml is located.

mvndeploy -Dmaven.test.skip=true -U

Uploaded successfully

Here we need to allow anonymous users to access the server (allow anonymous users to access the server)

Because the local Maven has no configured user

You can also use the idea maven command depoly

Jenkins build

1. Check the environment version

java-version#If not available, please refer to jdk1.8 installation above mvn-v#If not available, please refer to maven installation above git--version#If not available, please refer to git installation above

2. Install Jenkins

Add the Jenkins repository:

sudowget -O /etc/yum.repos.d/jenkins.repohttp://jenkins-ci.org/redhat/jenkins.reposudorpm --importhttp://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

3. Installation

yuminstalljenkins

4. Start

sudoservicejenkinsstart

5. Access

http://ip:8080/#jenkenisThe default is 8080

First time password:

vim /var/lib/jenkins/secrets/initialAdminPassword

Click to install the recommended plugin (I don’t know what to install when I choose to install it later)

Change the Jenkins port

vim/etc/sysconfig/jenkins

Change JENKINS_PORT="8080" ===> to the port you want to change that is not occupied JENKINS_PORT="8089"

Restart the service

servicejenkinsrestart

Problem encountered: Reinstalled JDK, java address changed

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

Follow the prompts and enter systemctl status jenkins.service

Solution:

1> View the current Java environment variables

echo$JAVA_HOME

2> Copy the Java environment variable address, edit the /etc/init.d/jenkins file, add the address to the specified location, and add the suffix /bin/java

vim/etc/init.d/jenkins

The key point is to configure Jenkins:

1. Configure global jdk maven git

Click Manage Jenkins (System Management) -> Global Tool Configuration (Global Tool Configuration)

1. Maven configuration: configure settings.xml address

2. Configure the jdk address (can be obtained using echo $JAVA_HOME )

3. The git configuration address can be viewed using (which -a git)

4. Maven configuration address

2. Create a new task

3. Configure tasks

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

Repository URL: the name of the repository to be accessed Credentials: the access account password or ssh certificate Branch Specifier (blank for 'any'): the branch to be accessed, multiple source code repositories can be used Browser: select the source code repository Server URL: source code repository URL Version: source code repository server version number

2. Configure the build

cleancompilepackageinstalldeploy-Dmaven.test.skip=true-U#Publish the jar

Then apply, the configuration is complete!

3. In my view -> find the newly created project --> click build now

Click on the build just now in the build history as shown below: #1: is the build id, console output: you can see the specific output

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

The error above is a project problem. You can see that the project has been pulled. So we must ensure the correctness of the project.

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

Background: gitlab nexus jenkins have all been completed

1. Download the project from gitlab and publish the jar to the private server

Reconfigure the gitlab address:

Configure Maven command:

cleancompilepackageinstalldeploy -Dmaven.test.skip=true -U

2. Publish the running jar to the specified machine

Make sure Jenkins has the Publish Over SSH plugin installed. Manage Jenkins -> Manage Plugins -> Search for ssh

Then configure ssh

After configuration, click Test Configuration and success will appear.

After the configuration is completed, the new Item (project) is just an additional build (note that the previous configuration needs to be changed:項目的git地址)

# Find the original process and kill it
pid=$(ps -ef | grep java | grep $Project_name | awk -F '[ ]+' '{print $2}')
kill -9 $pid
#Start jar
