jenkins rpm包安装
jenkins依赖java环境,启动jenkins要安装jdk
1.此次安装采用rpm包方式安装,版本为jenkins-2.234-1.1
2.jdk版本为: jdk-8u51-linux-x64.tar.gz
3.jenkins要结合mvn用,版本为:apache-maven-3.6.3-bin.tar.gz
4.jenkins安装完成后以root方式启动
5.服务器系统为centos7.6 X86_64位,关闭selinx ,开启iptables
二、jenkins具体安装过程
2.1安装jdk
[ soft]# tar xf /data/soft/jdk-8u51-linux-x64.tar.gz -C /usr/local/ [ soft]# cd /usr/local/ [ local]# ln -sv jdk1.8.0_51 jdk "jdk" -> "jdk1.8.0_51"
2.2安装maven
[ ~]# tar xf /data/soft/apache-maven-3.6.3-bin.tar.gz -C /usr/local/ [ ~]# ln -sv /usr/local/apache-maven-3.6.3 /usr/local/maven "/usr/local/maven" -> "/usr/local/apache-maven-3.6.3"
2.3添加环境变量:
[ ~]# tail -7 /etc/profile export MAVEN_HOME=/usr/local/maven export JAVA_HOME=/usr/local/jdk export JRE_HOME=/usr/local/jdk/jre export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH [ ~]# source /etc/profile [ ~]# which java /usr/local/jdk/bin/java [ ~]# which mvn /usr/local/maven/bin/mvn [ ~]# mvn -v Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven home: /usr/local/maven Java version: 1.8.0_51, vendor: Oracle Corporation, runtime: /usr/local/jdk1.8.0_51/jre Default locale: zh_CN, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix" [ ~]# java -version java version "1.8.0_51" Java(TM) SE Runtime Environment (build 1.8.0_51-b16) Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)
2.4 jenkins rpm包安装
rpm包下载地址:
https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/
插件下载地址如下:
http://mirror.serverion.com/jenkins/plugins/
[ soft]# wget -P /data/soft/ https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/jenkins-2.222.3-1.1.noarch.rpm [ soft]# rpm -ivh /data/soft/jenkins-2.234-1.1.noarch.rpm 警告:/data/soft/jenkins-2.234-1.1.noarch.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID 45f2c3d5: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:jenkins-2.234-1.1 ################################# [100%]
2.5准备jenkins配置文件
cp /etc/sysconfig/jenkins /etc/sysconfig/jenkins.ori [ data]# cat /etc/sysconfig/jenkins JENKINS_HOME="/data/jenkins" JENKINS_JAVA_CMD="/usr/local/jdk/bin/java" JENKINS_USER="root" JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Duser.timezone=Asia/Shanghai -Djava.util.logging.config.file=/etc/sysconfig/jenkins.logging.properties" JENKINS_PORT="55266"
2.6启动jenkins服务并让jenkins开机自启动:
[ ~]# /etc/init.d/jenkins start Starting jenkins (via systemctl): [ 确定 ] [ ~]# chkconfig jenkins on 或者: [ soft]# systemctl enable jenkins.service jenkins.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig jenkins on [ ~]# chkconfig --list|grep jenkins 注:该输出结果只显示 SysV 服务,并不包含 原生 systemd 服务。SysV 配置数据 可能被原生 systemd 配置覆盖。 要列出 systemd 服务,请执行 ‘systemctl list-unit-files‘。 查看在具体 target 启用的服务请执行 ‘systemctl list-dependencies [target]‘。 jenkins 0:关 1:关 2:开 3:开 4:开 5:开 6:关
jenkins服务已经启动:
[ ~]# ss -lntup|grep java tcp LISTEN 0 50 :::55266 :::* users:(("java",pid=24246,fd=161)) [ ~]# ps -ef|grep jenkins root 24246 1 24 19:07 ? 00:00:26 /usr/local/jdk/bin/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -Duser.timezone=Asia/Shanghai -Djava.util.logging.config.file=/etc/sysconfig/jenkins.logging.properties -DJENKINS_HOME=/data/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=55266 root 24931 11970 0 19:09 pts/2 00:00:00 grep --color jenkins [ ~]#
2.7解锁Jenkins
浏览器访问:http://21.110.16.39:55266/
提示:到这里,先不急着去输入密码,我们可以在这里先把插件源换掉,这样可以加快后续安装插件的速度,失败的机率大大降低,也不会再初始化部分卡好久 我曾经卡过1个多小时
2.8替换jenkins插件源地址
修改hudson.model.UpdateCenter.xml 文件中https为http:
[ updates]# cat /data/jenkins/hudson.model.UpdateCenter.xml <?xml version=‘1.1‘ encoding=‘UTF-8‘?> <sites> <site> <id>default</id> <url>http://updates.jenkins.io/update-center.json</url> </site>
重启jenkins服务:
systemctl stop jenkins
systemctl start jenkins
/data/jenkins下面会生成updates文件:
[ jenkins]# ll /data/jenkins/updates/ 总用量 1900 -rw-r--r-- 1 root root 1936882 5月 4 08:33 default.json -rw-r--r-- 1 root root 5350 5月 4 08:33 hudson.tasks.Maven.MavenInstaller
要是没有生成updates文件夹的话,修改/data/jenkins/hudson.model.UpdateCenter.xml 也就是 修改默认Jenkins插件源与连接检测位置:
sed -i "s/http:\/\/updates.jenkins.io\/update-center.json/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins\/updates\/update-center.json/g" /data/jenkins/hudson.model.UpdateCenter.xml
要是修改完地址还没生成updates目录的话,可以尝试重启下jenkins服务试下:
systemctl restart jenkins
如果提示/data/jenkins/updates/default.json不存在,那么可能是你的网络连不到Jenkins官方仓库上,是不会生成updates目录的,解决方式也简单
执行如下命令,重启Jenkins,再查看updates文件夹是否生成
sed -i "s/http:\/\/updates.jenkins.io\/update-center.json/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins\/updates\/update-center.json/g" /data/jenkins/hudson.model.UpdateCenter.xml
重启jenkins服务,经测试,updates目录没有生成的话,主要还是你的网络连不到Jenkins官方仓库上。需要多次尝试重启下jenkins服务
如果/data/jenkins/updates/default.json文件生成了,则执行下面的命令替换掉默认的下载源:
sed -i ‘s/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g‘ /data/jenkins/updates/default.json sed -i ‘s/http:\/\/www.google.com/http:\/\/www.baidu.com/g‘ /data/jenkins/updates/default.json systemctl stop jenkins systemctl start jenkins
2.9正常替换掉下载源地址注册jenkins服务
从服务器找到密码文件输入密码
输入管理员账户和密码登录
提示:要是/data/jenkins/updates/default.json文件一直没生成的话,浏览器访问链接进行注册jenkins服务时会一直提示离线安装的
截图如下:
三、安装注册总结
Jenkins所谓的update site换源没什么用,每次在初次安装jenkins以及在jenkins安装完成后安装所需插件时,都要等好久,或者经常安装失败。
最终的解决办法如下:
换成清华源的同时,也要同时把下载插件包的地址也要换成清华的下载源,具体需要修改的配置文件:
[ ~]# cat /data/jenkins/hudson.model.UpdateCenter.xml <?xml version=‘1.1‘ encoding=‘UTF-8‘?> <sites> <site> <id>default</id> <url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url> </site> sed -i ‘s/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g‘ /data/jenkins/updates/default.json sed -i ‘s/http:\/\/www.google.com/http:\/\/www.baidu.com/g‘ /data/jenkins/updates/default.json systemctl restart jenkins
采用如上方式,比原先安装要快好多。
