Ubuntu18注册gitlab-runner并激活CI/CD

gitlab-runner安装

下载

sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-arm

设置执行权限

sudo chmod +x /usr/local/bin/gitlab-runner

创建 GitLab CI 用户

useradd --comment 'gitLab-runner' --create-home gitlab-runner --shell /bin/bash

运行服务

gitlab-runner start

gitlab-runner注册

打开 gitlab 项目 -> 设置 -> CI / CD -> Runners 设置，获取令牌

运行以下命令开始注册：

sudo gitlab-runner register

输入GitLab实例URL：

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com )
https://xxx.xxx

输入注册令牌来注册 Runner

Please enter the gitlab-ci token for this runner
xxx

输入 Runner 说明

Please enter the gitlab-ci description for this runner
[hostame] gitlab-runner

输入 Runner 的 tags

Please enter the gitlab-ci tags for this runner (comma separated):
tag

输入 Runner 执行方式

Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell:
shell

runner配置修改

.gitlab-ci.yml

要实现CI/CD，首先要在项目根路径下创建.gitlab-ci.yml文件，我的目录结构如下：

.gitlab-ci.yml文件内容：

# CI/CD管道分三步，这里可以根据需求自行配置
stages:
  - build
  - test
  - deploy
build:
  stage: build
  # 测试构建
  script:
    - gradle clean build -x test
test:
  stage: test
  # 这里可以写一些测试相关的脚本
  script:
    - echo SKIPPING TEST
deploy:
  stage: deploy
  script:
    # 修改部署脚本文件类型为可执行文件
    - chmod +x .gitlab-ci/deploy.sh
    # 执行脚本
    - sh .gitlab-ci/deploy.sh
  only:
    # 只有master分支执行这个步骤
    - /^master.*$/
  tags:
    # 对应注册runner时候的tag名
    - tag

deploy.sh文件内容：

#!/usr/bin/env bash

echo "Start deploying!"

gradle build

# 把文件从本地传到服务器上去
scp /home/gitlab-runner/builds/n637Af4S/0/root/project-test/build/libs/project-test-0.0.1-SNAPSHOT.jar root@服务器ip:/usr/local/project_test/project-test-0.0.1-SNAPSHOT.jar

# 执行服务器上的部署脚本文件
ssh root@服务器ip "sh /usr/local/project_test/deploy.sh"

echo "Deploy jar success!"

执行deploy.sh文件需要两个前提条件，一是需要gitlat服务器可以免密登录待部署服务器，而是要在待部署服务器上也创建一个deploy.sh文件。成功执行待部署服务器上的deploy.sh文件需要文件夹创建格式和我这里相同。

待部署服务器上的deploy.sh文件：

#!/bin/bash
#defined
export JAVA_HOME=/usr/local/java/jdk1.8.0_231


PID=`ps -ef | grep java | grep project-test | awk '{print $2}'`

if [ -z $PID_EXIST];then
echo the process $PID is not exist
else
echo the process $PID exist
kill -9 $PID
fi

echo "remover jar file"

rm -rf /jar/project-test*

echo "copy jar to dir"

cp project-test-0.0.1-SNAPSHOT.jar /usr/local/project_test/jar/project-test.jar

echo "start jar"

nohup java -jar /usr/local/project_test/jar/project-test.jar >/dev/null 2>&1 &

echo "started"

Q:提交代码后没有触发，一直停留在pending

A：报错：This job is stuck, because you don't have any active runners that can run this job.

原因：注册gitlab runner 的时候，有一步提示：Can run untagged jobs: [false/true]，默认值为false。

这句话的意思是：是否在没有标记tag的job上运行，如果选择默认值false，那没有标记tag的代码提交是不会触发gitlab runner的，如果做测试，最好填true。
