01启动jenkins

Jenkins最初是由日本人Kohsuke Kawaguchi在Sun公司主导开发，项目最初被称为Hudson。

环境初始化：

软件版本：jre 11, Jenkins 2.394,tomcat 8 jenkins 版本对jre版本有要求自行测试。

1. jdk

   #apt-get install fontconfig freetype2-demos
   yum install fontconfig freetype
   

   安装jdk
   wget https://download.java.net/java/ga/jdk11/openjdk-11_linux-x64_bin.tar.gz 
   tar xf openjdk-11_linux-x64_bin.tar.gz -C /opt
   ln -svf  /opt/{jdk-11,jdk}
   
   cat>>/etc/profile<<EOF
   export JAVA_HOME=/opt/jdk
   export JAVA_JRE=\$JAVA_HOME/jre
   export CLASSPATH=\$JAVA_HOME/lib:\$JAVA_HOME/jre/lib
   export PATH=\$JAVA_HOME/bin:\$JAVA_JRE/bin:$PATH:.
   EOF
   
   source /etc/profile
   
   [root@lavm-ioreaqndwv ~]# java -version
   openjdk version "11" 2018-09-25
   OpenJDK Runtime Environment 18.9 (build 11+28)
   OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)
   
   

   _{java11及以上本版提示缺少java.lang 文件，解决办法从java8中拷贝issue}

   cp jdk1.8.0_391/jre/lib/fontconfig.bfc /opt/jdk/lib/
   
   cp -a jdk1.8.0_391/jre/lib/fonts/ /opt/jdk/lib/
   

2. tomcat

   wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.99/bin/apache-tomcat-8.5.99.tar.gz
   
   tar xf apache-tomcat-8.5.99.tar.gz -C /opt
   ln -svf /opt/apache-tomcat-8.5.99/ /opt/tomcat
   

3. jenkins

   wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/war/2.394/jenkins.war
   

启动jenkins

1. 通过tomcat启动

   部署war包

   cp  jenkins.war /opt/tomcat/webapps/
   

   启动tomcat

   # 前台启动
   /opt/tomcat/bin/catalina.sh run 
   

   # 守护进程启动
   /opt/tomcat/bin/catalina.sh start
   /opt/tomcat/bin/catalina.sh stop 
   

   访问jenkins

   # 初始化密码位置 cat /$USER/.jenkins/secrets/initialAdminPassword 
   http://localhost:8080/jenkins/
   

2. 通过java -jar jenkins.var 启动

   启动

   _{Jenkins内置jetty应用服务器,Jetty 是 Java 实现的一个轻量级的 Servlet 容器}

   java -jar jenkins.war
   

   访问jenkins

   # 初始化密码位置 cat /$USER/.jenkins/secrets/initialAdminPassword 
   http://localhost:8080
   

   该方式支持一些参数和java 环境变量

   --httpPort=8080
   --httpsPort=8083
   --prefix=/jenkins
   --webroot=/var/cache/jenkins
   --argumentsRealm.passwd.admin=admin
   --argumentsRealm.roles.admin=admin
   --httpsPrivateKey=/var/lib/jenkins/pk
   --httpsCertificate=/var/lib/jenkins/cert
   

   -Djenkins.install.runSetupWizard=true
   -Djenkins.security.ApiTokenProperty.adminCanGenerateNewTokens=false
   -Dcom.cloudbees.hudson.plugins.folder.computed.ThrottleComputationQueueTaskDispatcher.LIMIT=10
   

3. 通过docker启动

   docker run -p 9090:8080 --rm jenkinszh/jenkins-zh:2.238
   docker run -p 9090:8080 --rm jenkins/jenkins:2.238
