使用yum安装Jenkins

一、安装之前

  1. 1.安装Jenkins所依赖的jdk
  2. yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel

二、安装

  1. 2.安装方法1
  2. sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
  3. sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
  4. yum install -y jenkins
  6. #安装方法2
  7. wget https://pkg.jenkins.io/redhat/jenkins-2.156-1.1.noarch.rpm
  8. rpm -ivh jenkins-2.156-1.1.noarch.rpm

三、创建文件与授权

  1. mkdir -p /var/lib/jenkins
  2. mkdir -p /var/cache/jenkins
  3. mkdir -p /var/log/jenkins
  5. chown -R root:root /var/lib/jenkins
  6. chown -R root:root /var/cache/jenkins
  7. chown -R root:root /var/log/jenkins

四、设置调整防火墙

FirewallD是Centos 8上的默认防火墙解决方案
在安装过程中，Nginx使用预定义的规则创建防火墙服务文件，以允许访问HTTP（80）和 HTTPS（443） 端口

  1. 3.使用以下命令永久打开必要的端口
  2. systemctl start firewalld
  3. sudo firewall-cmd --permanent --zone=public --add-service=http
  4. sudo firewall-cmd --permanent --zone=public --add-service=https
  5. firewall-cmd --zone=public --add-port=7001/tcp --permanent
  6. firewall-cmd --zone=public --add-port=8080/tcp --permanent
  7. firewall-cmd --zone=public --add-port=8888/tcp --permanent
  8. firewall-cmd --zone=public --add-port=27017/tcp --permanent
  9. sudo firewall-cmd --reload
  10. systemctl restart firewalld

五、设置jenkins配置

输入命令 vim /etc/sysconfig/jenkins 进入编辑模式 ggdG 全删 ggyG 全部复制 ggvG ggVG 高亮显示

快速部署Jenkins

  1. yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
  3. sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
  4. sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
  5. yum install -y jenkins
  7. mkdir -p /var/lib/jenkins
  8. mkdir -p /var/cache/jenkins
  9. mkdir -p /var/log/jenkins
  11. chown -R root:root /var/lib/jenkins
  12. chown -R root:root /var/cache/jenkins
  13. chown -R root:root /var/log/jenkins
  15. systemctl start firewalld

点击定位配置jenkins文件的位置

查看

  1. #执行命令查看密码
  2. cat /var/lib/jenkins/secrets/initialAdminPassword
  4. #检查是否已安装JDK,以下命令二选一，中括号选一即可
  5. yum list installed | grep [java][jdk]
  6. rpm -qa | grep [java][jdk][gcj]
  9. #查看centos系统版本
  10. cat /etc/redhat-release 
  12. #查看部署的库主目录
  13. ls /var/lib/jenkins/

修改密码

1. 查找jenkins的路径

  1. #方法1：
  2. [root@iZedbi0f3jvy9lZ ~]# whereis jenkins
  3. jenkins: /usr/lib/jenkins
  5. #方法2：
  6. [root@iZedbi0f3jvy9lZ ~]# find / -name config.xml
  7. /var/lib/jenkins/jobs/gitee test/config.xml
  8. /var/lib/jenkins/users/kim_1794366939214431569/config.xml
  9. /var/lib/jenkins/config.xml

2. 修改目录

  1. #方法1:
  2. 修改config.xml文件
  3. 找到关键词 useSecurity, 把后面的值 true 改为false
  4. 可以无账号和密码登录Jenkins
  6. #方法2:
  7. 打开该配置文件找到<passwordHash>节点
  8. 将#jbcrypt:后面的内容替换成
  9. $2a$10$d6oDwJRKYlWQMOKhW/Mi0eNq4xs/utxvfHLeWBUeeXbQLN9vpNhuK
  10. 即可

上面那串如何生成的呢？
Jenkins采用Java加密工具jBCrypt，所以我们在生成密码的时候需要添加相关的jar包。

  1. <dependency>
  2.     <groupId>org.mindrot</groupId>
  3.     <artifactId>jbcrypt</artifactId>
  4.     <version>0.4</version>
  5. </dependency>
  1. public class Test {
  2.   public static void main(String[] args) {
  3.     // 加密
  4.     String admin = BCrypt.hashpw("admin", BCrypt.gensalt());
  5.     System.out.println("加密：" + admin);
  7.     // 解密
  8.     if (BCrypt.checkpw("admin", admin)) {
  9.       System.out.println("is match");
  10.     } else {
  11.       System.out.println("is not match");
  12.     }
  13.   }
  14. }

3. 重启 Jenkins

  1. /etc/init.d/jenkins restart
  2. 或
  3. sudo systemctl restart jenkins

插件

Git Parameter

Extended Choice Parameter

  1. #覆盖内容
  2. echo "abc==master,develop,test" > /opt/jenkins.properties
  4. #追加内容
  5. echo "abc=master,develop,test" >> /opt/jenkins.properties
  7. #cat  用户保存下的路径/jenkins.property > /opt/jenkins.property

错误解决

错误信息为Starting Jenkins bash: /usr/bin/java: No such file or directory是java环境配置的问题

  1. yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
  2. #或者如下命令，安装jdk1.8.0的所有文件
  3. #yum install -y java-1.8.0-openjdk*
  4. #ln -s /usr/local/java/jdk1.8.0_171/bin/java /usr/bin/java
