DEVOPS技術實踐_01:jenkins集成平臺
一、準備環境
準備三臺機器
| 角色 | IP地址 | 用戶名 | 密碼 |
| jenkins-master | 172.25.254.130 | admin | meiyoumima |
| gitlab | 172.25.254.131 | tseter | meiyoumima |
| jenkins-slave（Maven | 172.25.254.134 | N/A | N/A |
二、jenkins-master安裝
2.1 安裝Java
[[email protected] ~]# yum install java-1.8.0-openjdk-devel.x86_64
[[email protected] ~]# vi /etc/profile
export JAVA_HOME=/usr/lib/jvm/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin
[[email protected] ~]# source /etc/profile
[[email protected] ~]# java -version
openjdk version "1.8.0_201" OpenJDK Runtime Environment (build 1.8.0_201-b09) OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode) [[email protected]-master ~]# vi /etc/profile
2.2 安裝jenkins
[[email protected] ~]# cd /usr/local/src/
[[email protected] src]# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war
[[email protected] src]# nohup java -jar /usr/local/src/jenkins.war --httpPort=9000 &
[[email protected] src]# tail -f nohup.out
Jenkins initial setup is required. An admin user has been created and a password generated. Please use the following password to proceed to installation: 5d3a5a8d50304bcf90845c6b55e4e280 This may also be found at: /root/.jenkins/secrets/initialAdminPassword
[[email protected] ~]# cat /root/.jenkins/secrets/initialAdminPassword
5d3a5a8d50304bcf90845c6b55e4e280
安裝插件
創建用戶
三、安裝gitlab
3.1 安裝依賴
[[email protected] ~]# yum install -y curl policycoreutils-python openssh-server
[[email protected] ~]# systemctl enable sshd
[[email protected] ~]# systemctl restart sshd
[[email protected] ~]# yum install -y postfix
[[email protected] ~]# firewall-cmd --add-service=ssh --permanent
[[email protected] ~]# firewall-cmd --add-service=http --permanent
[[email protected] ~]# firewall-cmd --reload
3.2 添加GitLab社區版Package
[[email protected] ~]# curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
[[email protected] ~]# yum install -y gitlab-ce
3.3 配置GitLab站點Url
GitLab默認的配置文件路徑是/etc/gitlab/gitlab.rb
默認的站點Url配置項是：external_url ‘http://gitlab.example.com‘
這裏我將GitLab站點Url修改external_url ‘http://172.25.254.131‘
3.4 啟動gitlab
[[email protected] ~]# gitlab-ctl reconfigure
Running handlers: Running handlers complete Chef Client finished, 475/1268 resources updated in 03 minutes 23 seconds gitlab Reconfigured!
四、jenkins配置slave
4.1 master端配置
點擊系統管理------------------->全局安全配置----------------->設置TCP端口
系統管理-節點管理-新建節點：
店家slave1
4.2 配置slave
在slave節點上安裝agent.jar
[[email protected] ~]# yum -y install java-1.8.0-openjdk-devel.x86_64
[[email protected] ~]# vim /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin
[[email protected] ~]# java -version
openjdk version "1.8.0_201" OpenJDK Runtime Environment (build 1.8.0_201-b09) OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)
[[email protected] ~]# mkdir /usr/local/jenkins-slave
[[email protected] ~]# cd /usr/local/jenkins-slave/
[[email protected] jenkins-slave]# ll
-rw-r--r--. 1 root root 789283 Apr 19 2019 agent.jar
根據提示執行
[[email protected] jenkins-slave]# java -jar agent.jar -jnlpUrl http://172.25.254.130:9000/computer/slave1/slave-agent.jnlp -secret e8b183c671c0f5efa09380c04bc54dedd1299528d2fce5d358a4c7b7b5af437d -workDir "/var/jenkins"
放後臺啟動
[[email protected] jenkins-slave]#nohup java -jar agent.jar -jnlpUrl http://172.25.254.130:9000/computer/slave1/slave-agent.jnlp -secret e8b183c671c0f5efa09380c04bc54dedd1299528d2fce5d358a4c7b7b5af437d -workDir "/var/jenkins" &
[[email protected] jenkins-slave]# tail nohup.out
Apr 10, 2019 10:26:15 PM hudson.remoting.jnlp.Main$CuiListener status INFO: Handshaking Apr 10, 2019 10:26:15 PM hudson.remoting.jnlp.Main$CuiListener status INFO: Connecting to 172.25.254.130:8181 Apr 10, 2019 10:26:15 PM hudson.remoting.jnlp.Main$CuiListener status INFO: Trying protocol: JNLP4-connect Apr 10, 2019 10:26:15 PM hudson.remoting.jnlp.Main$CuiListener status INFO: Remote identity confirmed: e7:b8:51:28:e5:14:c4:3f:a2:ca:9d:08:01:20:7a:ce Apr 10, 2019 10:26:16 PM hudson.remoting.jnlp.Main$CuiListener status INFO: Connected

成功連接
五、Jenkins構建maven項目
5.1安裝maven
[[email protected] jenkins-slave]# mkdir /usr/local/maven
[[email protected] jenkins-slave]# cd /usr/local/maven
[[email protected] maven]# wget http://apache.communilink.net/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz
[[email protected] maven]# tar -xf apache-maven-3.6.1-bin.tar.gz
[[email protected] maven]# ll
total 8924 drwxr-xr-x. 6 root root 99 Apr 10 22:56 apache-maven-3.6.1 -rw-r--r--. 1 root root 9136463 Apr 5 03:30 apache-maven-3.6.1-bin.tar.gz
[[email protected] maven]# cd apache-maven-3.6.1
[[email protected] apache-maven-3.6.1]# pwd
/usr/local/maven/apache-maven-3.6.1
[[email protected] apache-maven-3.6.1]# vim /etc/profile
export M2_HOME=/usr/local/maven/apache-maven-3.6.1 export PATH=$PATH:$M2_HOME/bin
[[email protected] apache-maven-3.6.1]# mvn -version
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
是因為Java的環境變量配置錯誤
修改
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin export M2_HOME=/usr/local/maven/apache-maven-3.6.1 export PATH=$PATH:$M2_HOME/bin
[[email protected] apache-maven-3.6.1]# source /etc/profile
[[email protected] apache-maven-3.6.1]# mvn -version

5.2簡單測試Maven項目
在github找一個maven項目
https://github.com/initcron/mvn-test
[[email protected] ~]# mkdir /git
[[email protected] ~]# cd /git
[[email protected] git]# git clone https://github.com/initcron/mvn-test
[[email protected] git]# ll
drwxr-xr-x. 4 root root 44 Apr 11 00:09 mvn-test
[[email protected] git]# cd mvn-test/
[[email protected] mvn-test]# ll
所有的maven項目都有一個pom.xml的文件
5.3 maven簡單用法
[[email protected] mvn-test]# mvn clean #清除緩存數據
[INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 8.527 s [INFO] Finished at: 2019-04-11T00:15:03+08:00

會生成一個target目錄
5.4 測試
[[email protected] mvn-test]# mvn test
[[email protected] mvn-test]# ll
drwxr-xr-x. 7 root root 141 Apr 11 00:22 target
[[email protected] mvn-test]# cd target/
[[email protected] target]# ll
drwxr-xr-x. 3 root root 17 Apr 11 00:19 classes -rw-r--r--. 1 root root 2275 Apr 11 00:20 maven-app-1.3-SNAPSHOT.jar #生成一個可以直接運行的jar包 drwxr-xr-x. 2 root root 28 Apr 11 00:20 maven-archiver drwxr-xr-x. 3 root root 35 Apr 11 00:19 maven-status drwxr-xr-x. 2 root root 81 Apr 11 00:20 surefire-reports drwxr-xr-x. 3 root root 17 Apr 11 00:19 test-classes
[[email protected] target]# java -jar maven-app-1.3-SNAPSHOT.jar
上傳到自己本地的倉庫
六、手動構建項目
6.1 創建一個新的project
6.2 把這個項目clone到本地
[[email protected] mvn-test01]# cd /git/
[[email protected] git]# git clone http://172.25.254.131/tester/mvn-test01.git
[[email protected] git]# ll
drwxr-xr-x. 5 root root 58 Apr 11 00:19 mvn-test drwxr-xr-x. 3 root root 18 Apr 11 00:38 mvn-test01
[[email protected] mvn-test01]# mv ../mvn-test/* ./
[[email protected] mvn-test01]# ll
-rw-r--r--. 1 root root 646 Apr 11 00:09 pom.xml drwxr-xr-x. 4 root root 30 Apr 11 00:09 src drwxr-xr-x. 7 root root 141 Apr 11 00:22 target
6.3 提交
[[email protected] mvn-test01]# git add *
[[email protected] mvn-test01]# git commit -m ‘test‘
