devops-jenkins部署和基本使用
1. jenkins部署和基本使用
1.1) 先关闭centos 7的自带防火墙和selinux
[root@test-2 ~]# /bin/systemctl stop firewalld [root@test-2 ~]# /bin/systemctl disable firewalld [root@localhost ~]# getenforce #查看selinux是否开启 Enforcing #enforcing表示selinux开启的， [root@test-2 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config #修改配置文件，需要重启才后永久关闭 [root@test-2 ~]# setenforce 0 #临时关闭selinx [root@test-2 ~]# getenforce #查看是否关闭 Disabled
1.2) 下载jenkins官方包安装
jenkins官方下载地址： http://pkg.jenkins.io/
点击红色下载地址进入
1.3) 安装jdk的java应用程序
[root@jenkins ~]# yum install -y java-1.8.0
1.4) 验证jdk是否正常
[root@jenkins ~]# java -version openjdk version "1.8.0_191" OpenJDK Runtime Environment (build 1.8.0_191-b12) OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
1.5) 下载jenkins的源，进行jenkins源的安装
[root@jenkins ~]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo #导入jenkins源 [root@jenkins ~]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key #导入官方jenkins证书
1.6) 安装jenkins
root@jenkins ~]# yum install jenkins #安装jenkins Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.aliyun.com * extras: mirrors.cn99.com * updates: mirrors.cn99.com jenkins | 2.9 kB 00:00:00 jenkins/primary_db | 26 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package jenkins.noarch 0:2.150.2-1.1 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================= Package Arch Version Repository Size ======================================================================================================================================================= Installing: jenkins noarch 2.150.2-1.1 jenkins 72 M Transaction Summary ======================================================================================================================================================= Install 1 Package Total download size: 72 M Installed size: 72 M Is this ok [y/d/N]: y Downloading packages: jenkins-2.150.2-1.1.noarch.rpm | 72 MB 00:00:09 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : jenkins-2.150.2-1.1.noarch 1/1 Verifying : jenkins-2.150.2-1.1.noarch 1/1 Installed: jenkins.noarch 0:2.150.2-1.1 Complete! [root@jenkins ~]# rpm -ql jenkins #安装的文件列表 /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
1.7) 安装完成了，启动jenkins
[root@jenkins ~]# /bin/systemctl start jenkins [root@jenkins ~]# /bin/systemctl enable jenkins jenkins.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig jenkins on [root@jenkins ~]# netstat -lntup | grep 80 tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 1710/java [root@jenkins ~]# ps -ef |grep java jenkins 1710 1 14 16:53 ? 00:00:37 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20 root 1816 1339 0 16:58 pts/0 00:00:00 grep --color=auto java
2. jenkins启动完成后浏览器访问
2.1) 浏览器访问 “http://localhost:8080”
2.2) 管理密码获取
[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword #查看密码 97d6ab7b8b8745ef8771455be60de68a #注释：将查看到密码复制到浏览器密码框里
2.3) 安装插件
解决：安装jenkins时web界面出现该jenkins实例似乎已离线
(1) 修改 /var/lib/jenkins/updates/default.json 文件，把www.google.com修改为www.baidu.com
解释：jenkins在下载插件之前会先检查网络连接，其会读取这个文件中的网址。默认是：访问谷歌，在国内是无法访问谷歌的，所以要修改为我们国内的连接的地址：www.baidu.com
(2) 修改 /var/lib/jenkins/hudson.model.UpdateCenter.xml
解释：该文件是jenkins下载插件的源地址，更改地址默认jenkins默认为的：https://updates.jenkins.io/update-center.json 就是因为https的问题更改为：http://updates.jenkins.io/update-center.json
[root@jenkins ~]# vim /var/lib/jenkins/hudson.model.UpdateCenter.xml [root@jenkins ~]# cat /var/lib/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> </sites>
2.4) 重启jenkins服务
[root@jenkins ~]# /bin/systemctl restart jenkins
[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword #查看密码 97d6ab7b8b8745ef8771455be60de68a #注释：将查看到密码复制到浏览器密码框里
我们选择推荐自定义选择安装
安装效果
2.5) 创建第一个管理员用户
提示，配置用户时必须添加邮箱
进入到登录界面了
登录后的界面
3. jenkins的配置文件
[root@jenkins ~]# vim /etc/sysconfig/jenkins
4. jenkins添加插件
4.1） jenkins添加gitlab插件
4.2) 插件安装blue Ocean
