Build Jenkins+springcloud one-click automatic deployment

Enterprise 2023-04-08 21:57:45 views: null

Use jenkins to realize automatic project deployment notes

1. Purpose

1. One-click realization of project automatic construction, packaging and release (for production environment)

2. Realize that the code is submitted to the code warehouse and automatically packaged and deployed immediately (for the test environment)

3. The test script code is at the end

2. Operating environment

  • hundreds

  • jdk

  • maven

  • jenkins

  • gitee

  • git

  • docker

2. Implementation idea

1. Production environment

  1. Merge the code development branch to the master branch, ready to release the latest code

  2. Jenkins one-click release

  3. Jenkins pulls the latest code from the code repository

  4. Packaging via maven

  5. Package the jar package into a mirror image and upload it to your own mirror warehouse private server

  6. Jenkins notifies the application server to pull the latest image

  7. The application server pulls the latest image and runs the new container

  8. Delete old containers and images

  9. If the release fails, roll back to the previous version

2. Test environment, development environment

  1. Submit code to code warehouse dev or other branches

  2. Automatically trigger jenkins to build the project

  3. Jenkins pulls the latest code from the code repository

  4. Copy the latest code to the test server

  5. Automatically connect to the test server for maven packaging

  6. Package the jar package into a mirror image

  7. Delete old containers and images

  8. Run the new container from the newly packaged image

3. Preliminary preparation

  1. Two centos servers can ping each other (or two virtual machines)

  2. Prepare a springcloud or springboot project for automatic release testing (I am preparing a multi-module project here, the directory structure is as follows)

    picture

  3. jdk 1.8 installation package, maven 3.6 package

  • jdk download address: https://wp.boytian.com/#/s/p8Fv password tiantian123

  • maven download address: https://wp.boytian.com/#/s/2lc1 password tiantian321

4. Install jdk environment and maven environment

“

It is best to install both, here is a demonstration of a server

”

1. jdk environment installation

  1. Create jdk storage directorymkdir -p /home/jdk

  2. Upload jdk to this directory, enter this directory and decompress, decompress command:tar -zxvf jdk-8u144-linux-x64.tar.g

    picture

2. maven installation

  1. Create maven directory and maven warehouse directory

  • mkdir -p /home/maven

  • mkdir -p /home/maven/repo

  1. Upload maven to /home/maven/the directory, enter the directory and decompress, decompress command:tar -zxvf apache-maven-3.6.3

3. Configure the environment variables of jdk and maven

  1. modify /etc/profilethe file, the commandvim /etc/profile

  2. If the directory creation is consistent with mine, add the following configuration at the bottom, otherwise you can modify it yourself

    #输入i 进入编辑模式

# java配置
export JAVA_HOME=/home/jdk/jdk1.8.0_144
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/bin

#maven 配置
export MAVEN_HOME=/home/maven/apache-maven-3.6.3
export PATH=$MAVEN_HOME/bin:$PATH

  3. Refresh the configuration to take effect

  • source /etc/profile

  1. To test whether the environment is effective, the commandjava mvn -v

    picture

  2. Another server host is also configured

5. Configure secret-free login (two servers log in without secret each other)

  1. Enter ssh-keygen -t rsaand hit three carriage returns

  2. Enter ssh-copy-id -i ~/.ssh/id_rsa.pub ip地址Enter

  3. Enter the password verification of the second server to realize password-free login

  4. In the same way, configure the second server to log in to the first server without password

”

6. Install the jenkin service on the first server

1. Execute the following commands in sequence on the first server installation

  • sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

  • sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

  • yum install jenkins

  • ln -s /home/jdk/jdk1.8.0_144/bin/java /usr/bin/java

  • sudo ln -s /home/maven/apache-maven-3.6.3 /usr/local/maven

  • systemctl start jenkins

“

(1, 2, 3) is to install jenkins, (4, 5) is the soft link environment command to the usr directory (6) start Jenkins

”

2. Modify the authority of jenkins to root authority, so as to facilitate the problem of insufficient authority to execute commands in the future
# 打开配置文件
vim /etc/sysconfig/jenkins
# 修改$JENKINS_USER
$JENKINS_USER="root"

#修改Jenkins相关文件夹用户权限
chown -R root:root /var/lib/jenkins
chown -R root:root /var/cache/jenkins
chown -R root:root /var/log/jenkins

#重启
systemctl restart jenkins

7. Access the jenkins service for some basic configuration

  1. Browser access: ip:8080

  1. Get the password command from the server:cat /var/lib/jenkins/secrets/initialAdminPassword

  1. Install custom plugins

  1. Install the gitee plugin, push code to gitee is mainly triggered by this plugin

    picture

  2. Configure gitee interaction credentials

10. Automated deployment scripts

“

The automatic build configuration is completed, and then write a script for the real deployment project

The content of the script is as follows. Currently, the function is implemented but it is still not perfect. It will be improved later

ENV JAVA_OPTS="-Xmx512m -Xms512m -Xmn512m -Xss256K -XX:SurvivorRatio=8 -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -XX:+UseConcMarkSweepGC -XX:ConcGCThreads=4 -XX:+CMSClassUnloadingEnabled -Dfile.encoding=UTF-8 -XX:+DisableExplicitGC -XX:+PrintGC -XX:+PrintGCTimeStamps -Xloggc:./gc.log"
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

  3. Modify the jenkins shell configuration just now as follows

    #!/bin/bash
chmod u+x run.sh # 一行是赋予脚本执行权限
./run.sh #一行是执行脚本
