gitlab-runner註冊

開啟 gitlab 專案 -> 設定 -> CI / CD -> Runners 設定，獲取令牌

執行以下命令開始註冊：

sudo gitlab-runner register

輸入GitLab例項URL：

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

輸入註冊令牌來註冊 Runner

Please enter the gitlab-ci token for this runner
xxx

輸入 Runner 說明

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

輸入 Runner 的 tags

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

輸入 Runner 執行方式

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

驗證

runner配置修改

.gitlab-ci.yml

要實現CI/CD，首先要在專案根路徑下建立.gitlab-ci.yml檔案，我的目錄結構如下：

.gitlab-ci.yml檔案內容：

# CI/CD管道分三步，這裡可以根據需求自行配置
stages:
  - build
  - test
  - deploy
build:
  stage: build
  # 測試構建
  script:
    - gradle clean build -x test
test:
  stage: test
  # 這裡可以寫一些測試相關的指令碼
  script:
    - echo SKIPPING TEST
deploy:
  stage: deploy
  script:
    # 修改部署指令碼檔案型別為可執行檔案
    - chmod +x .gitlab-ci/deploy.sh
    # 執行指令碼
    - sh .gitlab-ci/deploy.sh
  only:
    # 只有master分支執行這個步驟
    - /^master.*$/
  tags:
    # 對應註冊runner時候的tag名
    - tag

deploy.sh檔案內容：

#!/usr/bin/env bash

echo "Start deploying!"

gradle build

# 把檔案從本地傳到伺服器上去
scp /home/gitlab-runner/builds/n637Af4S/0/root/project-test/build/libs/project-test-0.0.1-SNAPSHOT.jar root@伺服器ip:/usr/local/project_test/project-test-0.0.1-SNAPSHOT.jar

# 執行伺服器上的部署指令碼檔案
ssh root@伺服器ip "sh /usr/local/project_test/deploy.sh"

echo "Deploy jar success!"

執行deploy.sh檔案需要兩個前提條件，一是需要gitlat伺服器可以免密登入待部署伺服器，而是要在待部署伺服器上也建立一個deploy.sh檔案。成功執行待部署伺服器上的deploy.sh檔案需要資料夾建立格式和我這裡相同。

待部署伺服器上的deploy.sh檔案：

#!/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:提交程式碼後沒有觸發，一直停留在pending

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

原因：註冊gitlab runner 的時候，有一步提示：Can run untagged jobs: [false/true]，預設值為false。

這句話的意思是：是否在沒有標記tag的job上執行，如果選擇預設值false，那沒有標記tag的程式碼提交是不會觸發gitlab runner的，如果做測試，最好填true。

Q: bash:行91: git:未找到命令

A：gitlab伺服器需要安裝git

Q:bash:行90: gradle:未找到命令

A：gitlab伺服器需要安裝gradle
