jenkins+gitlab持续集成图文教程

需要准备的环境：

1、jdk

2、maven

3、git

安装jenkins

1、下载地址：https://jenkins.io/index.html

2、稳定版本下载安装：

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo

sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

sudo yum install jenkins

3、修改jenkins端口默认8080：

vim /etc/sysconfig/jenkins

4、jenkins 目录位置：

Jenkins安装目录: /usr/lib/jenkins

Jenkins工作目录: /var/lib/jenkins(对应于环境变量 JENKINS_HOME)

构建项目源码目录：/var/lib/jenkins/workspace

日志默认路径：/var/log/jenkins/jenkins.log

jenkins配置文件：/etc/sysconfig/jenkins

jenkins启动脚本：/etc/init.d/jenkins

5、启动：service jenkins start

有可能出现错误：“Starting Jenkins -bash: /usr/bin/java: No such file or directory”,或Starting jenkins (via systemctl): Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.如图：

这表示找不到Jenkins找不到java

解决方法：vim /etc/init.d/jenkins，把java路径加上,如下图

卸载jenkins

service jenkins stopyum clean allyum -y remove jenkinsrm -rf /var/cache/jenkinsrm -rf /var/lib/jenkins/

配置jenkins

1、初始密码获取：

cat /var/lib/jenkins/secrets/initialAdminPassword

2、启动后插件无法加载：

在$JENKINS_HOME/hudson.model.UpdateCenter.xml文件中，默认url

<url>http://updates.jenkins-ci.org/update-center.json</url>

替换成：<url>http://mirror.xmission.com/jenkins/updates/update-center.json</url>

vim /var/lib/jenkins/hudson.model.UpdateCenter.xml

3、插件下载

常用插件：Deploy to container Plugin，Git plugin，Maven Integration plugin，Publish Over SSH，SSH plugin，Role-based Authorization Strategy

4、权限配置：系统管理 --> 全局安全配置

如果权限没有配置好，首页进入是空白的，做以下修改：

vim /var/lib/jenkins/config.xml

<authorizationStrategy class="hudson.security.GlobalMatrixAuthorizationStrategy">
<permission>hudson.model.Hudson.Administer:authenticated</permission>
</authorizationStrategy>
