關於Gitlab CI與Gitlab Runner的概念自行百度，此處不做贅述；Gitlab8.0之後已經集成了Gitlab CI；整合環境：CentOS6.5+Gitlab8.2.3-4+Gitlab Runner1.10.7-1

1、新增GitLab官方庫

curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash

2、安裝Gitlab Runner（若安裝其他版本，請參考官方文件）

yum install gitlab-ci
 
-multi-runner-1.10.7-1

3、註冊Gitlab Runner（Gitlab CI的url和token請從自己的gitlab裡面的專案裡的runners模組裡面檢視）

[root@localhost ~]# gitlab-ci-multi-runner register
Running in system-mode.                            

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://192.168.4.241:81/ci
Please enter the gitlab-ci token for
 
 this runner:
c5552857cfa2bd91c7b69507c8aec5
Please enter the gitlab-ci description for this runner:
[localhost.localdomain]: my-runner
Please enter the gitlab-ci tags for this runner (comma separated):
my-tag
Whether to run untagged builds [true/false]:
[false]: true
Registering runner... succeeded                     runner=c5552857
Please enter the executor
 
: parallels, shell, virtualbox, docker+machine, docker-ssh+machine, docker, docker-ssh, ssh, kubernetes:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 
[[email protected] ~]# 

4、啟動Gitlab Runner

gitlab-ci-multi-runner run

此時可以在你們專案裡看到剛剛新增的runner

5、在專案根目錄新增.gitlab-ci.yml檔案，Gitlab Runner執行全靠它（具體配置參考官方文件）

# Define commands that run before each job's script
before_script:
  - mvn clean

# Define build stages
stages:
  - deploy_test
  #- deploy_stage

# Define job
deploy_test_job:
  stage: deploy_test
  only:
      - develop
  script:
    # You can also list all environment variables with the export command
    #- export
    - mvn install -Ptest -DskipTests
    - sh /data/apps/tomcat-instance/deploy_test.sh

deploy_test.sh

#!/bin/sh
export JAVA_HOME=/data/apps/jdk1.8.0_111
export JRE_HOME=/data/apps/jdk1.8.0_111/jre
export CATALINA_HOME=/data/apps/tomcat-8.5.8
export CATALINA_BASE=/data/apps/tomcat-instance/jgj-api
war=/data/target/*.war
bin=$(cd `dirname $0`; pwd)
echo "Deploy ${war##*/}..."
rm -rf ${bin}/jgj-api/webapps/*
rm -rf ${bin}/jgj-api/logs/*
cp ${war} ${bin}/jgj-api/webapps/
echo "Restart tomcat.."
pid=$(lsof -t -i:8098)
if [ ! $pid ]; then
  echo "jgj-api pid not exist"
else
  echo "jgj-api pid is ${pid}"
  kill -9 $pid
fi
sleep 1

如果要部署其他環境可以通過ssh無密碼登入實現參考文件

這裡有一個弱點，至今沒找到解決辦法，就是在deploy_test.sh指令碼最後直接啟動tomcat，啟動不起來，應該是跟jenkins一樣，jenkins執行完job後會殺死其他程序，只不過jenkins有解決辦法，Gitlab Runner沒找到，各位大俠如果有辦法，歡迎留言！
