基于gitlab和jenkins的自动化部署实例
gitlab+jenkins服务简述：
GitLab是一个代码仓库，用来管理代码。Jenkins是一个自动化服务器，可以运行各种自动化构建、测试或部署任务。
所以这两者结合起来，就可以实现开发者提交代码到GitLab，Jenkins以一定频率自动运行测试、构建和部署的任务，
帮组开发团队更高效的集成和发布代码。
实验环境：
红帽7.3版本虚拟机
gitlab的安装配置,官网给的配置最低要求为4G，使用虚拟机配置的话结合物理机的配置要求分配内存：
[root@test1 ~]# yum install curl policycoreutils openssh-server openssh-clients postfix 安装依赖性
[root@test1 ~]# systemctl status postfix.service 查看服务状态确保开启
[root@test1 ~]# yum install -y net-tools 安装工具包
[root@test1 ~]# ls
gitlab-ce-11.2.0-ce.0.el7.x86_64.rpm
[root@test1 ~]# rpm -ivh gitlab-ce-11.2.0-ce.0.el7.x86_64.rpm 安装gitlab服务
安装过程比较慢因为是跟我们分配内存大小相关，安装成功会出来gitlab的图案：
[root@test1 ~]# vim /etc/gitlab/gitlab.rb 编辑配置文件写入当前主机IP，修改gitlab仓库路径
[root@test1 ~]# gitlab-ctl reconfigure 初始化gitlab
[root@test1 ~]# gitlab-ctl restart 重载服务
