##### 一. 基础环境准备 ###### 1. 关闭防火墙 关闭selinux ```bash systemctl stop firewalld setenforce 0 sed -i "s/SELINUX=.*$/SELINUX=disabled/g" /etc/selinux/config ``` ###### 2. 安装java ```bash 检查java是否安装，如果没有则先安装java环境：java -version cd && wget http://8.210.81.239/linux/java/install_jdk1.8.0_221.sh && source install_jdk1.8.0_221.sh ``` ##### 二 . 安装 Jenkins ###### 1.下载指定版本Jenkins-2.164.3 ```bash wget http://8.210.81.239/linux/Jenkins-2.164-1.1/jenkins-2.164-1.1.noarch.rpm ### https://mirrors.jenkins-ci.org/redhat/ ### 官网rpm包下载 不同版本要求的Java版本不一样 ``` ###### 2.安装 Jenkins ```bash rpm -ivh jenkins-2.164-1.1.noarch.rpm ``` ###### 3.配置 Jenkins 端口号 ```bash # vim /etc/sysconfig/jenkins 搜索 JENKINS_PORT 可以修改为指定端口号 ``` .配置Jenkins的JDK环境变量 ```bash # vim /etc/init.d/jenkins 搜索 candidates /etc/alternatives/java /usr/lib/jvm/java-1.8.0/bin/java /usr/lib/jvm/jre-1.8.0/bin/java /usr/lib/jvm/java-1.7.0/bin/java /usr/lib/jvm/jre-1.7.0/bin/java /usr/bin/java /opt/jdk1.8.0_221/bin/java 添加这一行 ``` 5.启动Jenkins 也可以最后启动 ```bash systemctl start jenkins ``` ##### 三. 安装maven 安装node 安装git 1.安装 Git ```bash # yum -y install git # which git ``` ###### 2.安装Maven ```bash # wget http://8.210.81.239/linux/Jenkins-2.164-1.1/apache-maven-3.5.4-bin.tar.gz # tar -xf apache-maven-3.5.4-bin.tar.gz # mv /root/apache-maven-3.5.4 /root/maven # mv apache-maven-3.5.4 /usr/local/maven # vim /etc/profile #maven export MAVEN_HOME=/usr/local/maven export PATH=$MAVEN_HOME/bin:$PATH # source /etc/profile # mvn -v 不行就看看是不是文件夹里面还有文件夹 ``` ###### 3.安装Node ```bash # wget http://8.210.81.239/linux/Jenkins-2.164-1.1/node-v16.10.0-linux-x64.tar.xz # tar -xf node-v16.10.0-linux-x64.tar.xz # mv node-v16.10.0-linux-x64 /usr/local/nodejs # vim /etc/profile #node export NODE_HOME=/usr/local/nodejs export PATH=$NODE_HOME/bin:$PATH export NODE_PATH=$NODE_HOME/lib/node_modules # source /etc/profile # node -v v16.10.0 # npm -v 7.24.0 ``` \# npm install -g cnpm --registry=https://registry.npm.taobao.org #安装包没有这个命令所以我需要安装以下，如果你的安装包有这个命令可以跳过这个步骤 ```bash # cnpm -v cnpm@9.0.1 (/usr/local/nodejs/lib/node_modules/cnpm/lib/parse_argv.js) npm@8.19.3 (/usr/local/nodejs/lib/node_modules/cnpm/node_modules/npm/index.js) node@16.10.0 (/usr/local/nodejs/bin/node) npminstall@7.3.1 (/usr/local/nodejs/lib/node_modules/cnpm/node_modules/npminstall/lib/index.js) prefix=/usr/local/nodejs linux x64 3.10.0-1160.80.1.el7.x86_64 registry=https://registry.npmmirror.com ``` ##### JDK错误解决方法 ###### 1.可以直接在配置文件配置`/etc/init.d下的jenkins文件`中增加现有jdk的路径 ```bash # vim /etc/init.d/jenkins 搜索 candidates /etc/alternatives/java /usr/lib/jvm/java-1.8.0/bin/java /usr/lib/jvm/jre-1.8.0/bin/java /usr/lib/jvm/java-1.7.0/bin/java /usr/lib/jvm/jre-1.7.0/bin/java /usr/bin/java /opt/jdk1.8.0_221/bin/java 添加这一行 ``` ###### 2.创建软链接 ```bash ln -s /opt/jdk1.8.0_221/bin/java /usr/bin/java systemctl start jenkins ``` ``` 参考文档: https://blog.csdn.net/zwjzone/article/details/125170820 参考文档: https://blog.csdn.net/qq_27229113/article/details/125522388 参考文档: https://blog.csdn.net/zwjzone/article/details/125170820 JDK错误 ``` ```bash 在Google中突然发现一篇修改端口踩坑的[文章](https://juejin.cn/post/7078601241542000654)，文章中提到使用systemctl 启动时不会使用上述的etc/init.d/jenkins配置文件。而是会使用/usr/lib/systemd/system/jenkins.service文件 所以使用vim打开该文件，查找了java相关的配置，找到了如下配置： vim /usr/lib/systemd/system/jenkins.service #Environment="JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64" 目前这行被注释了 ``` ##### 卸载 Jenkins ###### 1.卸载`yum`方式安装的`jenkins`（默认安装主目录是在`/var/lib/jenkins/`） ```bash service jenkins stop yum clean all yum -y remove jenkins ``` ###### 2.卸载`rpm`方式安装的`jenkins` ```bash 1. 卸载rpm方式安装的jenkins rpm -e jenkins 2. 检查是否卸载成功： rpm -ql jenkins 3. 彻底删除残留文件： find / -iname jenkins | xargs -n 1000 rm -rf 参考文档: https://blog.csdn.net/qq_25112523/article/details/100044027 ```
