[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/

[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

二、安装jenkins
[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
[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
[root@jenkins ~]# java -version

jenkins配置文件
[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:
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
[root@jenkins ~]# cat /var/lib/jenkins/users/admin_6975698030007194989/config.xml
[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
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
[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
https://updates.jenkins.io/update-center.json
清华源jenkins插件站点
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
[root@jenkins ~]#tar -zxvf plugins。tar。gz
[root@jenkins ~]#cd plugins
[root@jenkins plugins]#mv ./* /var/lib/jenkins/plugins
[root@jenkins ~]#systemctl restart jenkins
