Summary of server configuration gitlab-runner process problems

Purpose: Get rid of Jenkins deployment; if the front end has its own server environment; you can use gitlab-runner realize CI automatic deployment and send result notification messages

1. Server installation gitlab-runner

After confirming the server environment information, find the corresponding gitlab-runner installation package

1. Use uname -a view server version information
   
2. Here find the installation package that matches your version information

3. Use the installation package to install the gitlab-runner program; if it prompts sudo: curl: the command is not found, use yum install curl and then reinstall the program yum update -y && yum install curl -y (because the yum update will be performed before installing curl).

   sudo curl -L --output /usr/local/bin/gitlab-runner "https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64"

4. Given execution permission

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

5. Create a user

   sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

6. Install and run services

   sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
   sudo gitlab-runner start

   If this step also prompts sudo: gitlab-runner: command not found; required

   # 修改/etc/sudoers文件；找到这一行
   Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin  
   # 将要执行的命令所在的目录添加到后面，即可
   Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin 

   Re-execute the installation and run the service to continue

7. Verify installation information gitlab-runner -v


2. Configure and register the Runner

1. Find the corresponding information in your gitlab warehouse> Settings -> CI/CD -> Runners -> Specific Runners

2. Execute the registration command sudo gitlab-runner register

3. View the active Runner gitlab-runner verify

4. You can also see that it has been activated CI


3. Write yml configuration file

.gitlab-ci.yml script file in the root path of your own project

Write your own program

stages: # 分阶段
  - install
  - build
  - deploy
  - notify

cache: # 缓存内容
  paths:
    - node_modules/
    - dist/

install-job:
  tags: # 触发runner(这个就是注册的时候填写的tag)
    - master
  only: # 哪些分支触发
    - master
  stage: install # 当前阶段
  script:
    - echo '安装依赖阶段....'
    - npm install

build-job:
  tags:
    - master
  only:
    - master
  stage: build
  script:
    - npm run build:dev

deploy-job:
  tags:
    - master
  only:
    - master
  stage: deploy
  script:
    - whoami
    - sudo scp -r ./dist/* /www/html/kangshifu/kangshifu-vue/mars/dist


# 构建成功时的通知消息
notifySuccessWeChat:
  stage: notify
  script:
    - echo $title $sucContent
    - curl 'http://pushplus.hxtrip.com/send' -H 'Content-Type:application/json' -d "{\"token\":\"130a550e3a6d4dd2a019a98a5c022900\",\"title\":\"康师傅_前端_智云系统-部署结果(ci)\",\"content\":\"成功\",\"template\":\"html\",\"topic\":\"kangshifuFeZhiyun\"}"
  only:
    - master
  tags:
    - master
  when: on_success    

# 构建失败时的通知消息
notifyFailWeChat:
  stage: notify
  script:
    - curl 'http://pushplus.hxtrip.com/send' -H 'Content-Type:application/json' -d "{\"token\":\"130a550e3a6d4dd2a019a98a5c022900\",\"title\":\"康师傅_前端_智云系统-部署结果(ci)\",\"content\":\"失败\",\"template\":\"html\",\"topic\":\"kangshifuFeZhiyun\"}"
  only:
    - master
  tags:
    - master
  when: on_failure  

This script contains a notice deployment results; specific configurations can view corresponding documents configured, you can use nail message or enterprise micro-channel messages, etc.

   fatal: The remote end hung up unexpectedly
   Cleaning up project directory and file based variables
   00:00
   ERROR: Job failed: exit status 1
   
   原因：
   centos7 基础仓库，提供的 git 版本只有到 1.8.3，沒办法使用 git 2 的一些新功能
   
   解决方法：

2. Copy file problem
sshpass is not used to manipulate files; the currently used scp is used to manipulate files; you may be prompted

   报错： 
   We trust you have received the usual lecture from the local System
   Administrator. It usually boils down to these three things:
    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.
   sudo: no tty present and no askpass program specified
   Cleaning up project directory and file based variables
   00:00
   ERROR: Job failed: exit status 1
   
   原因：
   由于尝试使用sudo运行命令引起的 ，但是调用用户没有被授权使用 sudo
   
   解决：
   打开 sudoers 文件`vim /etc/sudoers` ；将以下内容添加到文件底部
   gitlab-runner ALL=(ALL) NOPASSWD: ALL

So far gitlab-runner can successfully run "Manual Spreading Flowers🎉"; you can also receive the push message of the deployment result
