一、安装JDK

bash 复制代码 
[root@jenkins ~]# ls
install.sh
jdk-8u361-linux-x64.tar.gz
jenkins-2.416-1.1.noarch.rpm
original-ks.cfg
[root@jenkins ~]# tar -xf  jdk-8u361-linux-x64.tar.gz
[root@jenkins ~]# ls
install.sh
jdk1.8.0_361
jdk-8u361-linux-x64.tar.gz
jenkins-2.416-1.1.noarch.rpm
original-ks.cfg
[root@jenkins ~]# mv jdk1.8.0_361/ /usr/local/
[root@jenkins ~]# ln -s  /usr/local/jdk1.8.0_361/  /usr/local/java
[root@jenkins ~]# ll  /usr/local/

-rwxr-xr-x   1 root root 6486345 Aug 10  2022 vm-agent
[root@jenkins ~]# vim /etc/profile

....

JAVA_HOME=/usr/local/java
PATH=$JAVA_HOME/bin:$PATH
export  JAVA_HOME PATH




[root@jenkins ~]# source /etc/profile
[root@jenkins ~]#  env |grep JAVA
JAVA_HOME=/usr/local/java
[root@jenkins ~]# java -version
java version "1.8.0_361"
Java(TM) SE Runtime Environment (build 1.8.0_361-b09)

二、安装jenkins

bash 复制代码 
[root@jenkins ~]# ls
install.sh                  jenkins-2.416-1.1.noarch.rpm
jdk-8u361-linux-x64.tar.gz  original-ks.cfg
[root@jenkins ~]# rpm -ivh jenkins-2.416-1.1.noarch.rpm 
warning: jenkins-2.416-1.1.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID ef5975ca: NOKEY

[root@jenkins ~]# systemctl daemon-reload

这里的报错，只需要安装跟jenkins匹配的版本即可

bash 复制代码 
[root@jenkins ~]# systemctl start jenkins
Job for jenkins.service failed because the control process exited with error code.
See "systemctl status jenkins.service" and "journalctl -xe" for details.
[root@jenkins ~]#  yum install fontconfig java-11-openjdk -y
bash 复制代码 
[root@jenkins ~]# java -version

[root@jenkins ~]# systemctl start jenkins
[root@jenkins ~]# systemctl status jenkins

jenkins配置文件

bash 复制代码 
[root@jenkinso1 learn_jenkins]# rpm -ql jenkins/etc/init.d/jenkins
/etc/logrotate.d/jenkins
/etc/sysconfig/jenkins
/usr/lib/jenkins/
usr/lib/jenkins/jenkins.war
/usr/sbin/rcjenkins
/var/cache/jenkins
/var/lib/jenkins
/var/log/jenkins

jenkins加载插件很多，非常吃内存，且所有操作都是io操作，需要系统1o速度较快，需要机器配置较高jenkins配置文件：

bash 复制代码 
jenkins配置文件： /etc/sysconfig/jenkins 
jenkins核心目录: /var/lib/jenkins
/usr/lib/jenkins/jenkins.war WAR包
/etc/sysconfig/jenkins 配置文件
/var/lib/jenkins/ 默认的JENKINS_HOME目录
/var/log/Jenkins/Jenkins.log Jenkins日志文件
/var/lib/jenkins/secrets/initialAdminPassword 存放初始密码
/var/lib/jenkins/plugins插件目录

jenkins 是由xml文件组成的，也是针对某个用户生成的

用户配置信息

bash 复制代码 
[root@jenkins ~]# cat /var/lib/jenkins/users/admin_6975698030007194989/config.xml
bash 复制代码 
[root@jenkins ~]# grep -Ev "^$|^#" /etc/sysconfig/jenkins //去掉注释
JENKINS_HOME="/var/lib/jenkins"  # jenkins主数据目录，数据备份，也只需要打包该文件即可
JENKINS_JAVA_CMD=""
JENKINS_USER="root"  # 启动用户
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true"
JENKINS_PORT="8080"  #启动端口
JENKINS_LISTEN_ADDRESS=""     # 监听地址
JENKINS_HTTPS_PORT=""
JENKINS_HTTPS_KEYSTORE=""
JENKINS_HTTPS_KEYSTORE_PASSWORD=""
JENKINS_HTTPS_LISTEN_ADDRESS=""
JENKINS_HTTP2_PORT=""
JENKINS_HTTP2_LISTEN_ADDRESS=""
JENKINS_DEBUG_LEVEL="5"
JENKINS_ENABLE_ACCESS_LOG="no"
JENKINS_ARGS=""

检查 jenkins 时间

bash 复制代码 
System.setProperty('org.apache.commons.jelly.tags.fmt.timeZone','Asia/Shanghai')

三、访问 Jenkins 初始化页面

1.访问http://`IP`:8080/

注意：需要在安全组开放端口


2.获取admin密码

bash 复制代码 
[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword 
8aa6ae338cbb42b8b8385a33c4048267 //密码

修改Jenkins 密码

修改成功，会自动退出

Jenkins 如何安装插件

  • 修改 jenkins 的插件下载源
  • 在页面上导入jenkins插件
  • 在服务器上，进行插件迁移

配置 jenkins 下载插件的代理

默认升级站点

bash 复制代码 
https://updates.jenkins.io/update-center.json

清华源jenkins插件站点

bash 复制代码 
https://mirrors.tuna.tsinghua.edu.cn/jenkins/plugins/

修改jenkins的下载源配置

服务器 jenkins 插件导入

bash 复制代码 
[root@jenkins ~]#tar -zxvf plugins。tar。gz
[root@jenkins ~]#cd plugins
[root@jenkins plugins]#mv ./* /var/lib/jenkins/plugins
[root@jenkins ~]#systemctl restart jenkins
