基于gitlab和jenkins的自动化部署实例
gitlab+jenkins服务简述：java
GitLab是一个代码仓库，用来管理代码。Jenkins是一个自动化服务器，能够运行各类自动化构建、测试或部署任务。 因此这二者结合起来，就能够实现开发者提交代码到GitLab，Jenkins以必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：linux
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：ios
[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
安装过程比较慢由于是跟咱们分配内存大小相关，安装成功会出来gitlab的图案：
git
[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

配置gitlab的免密链接：
web

在gitlab界面能够看到实时数据：
从新打开一台虚拟机配置jenkins：vim
[root@localhost ~]# ls [root@localhost ~]# route -n 查看网关 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.25.0.0 0.0.0.0 255.255.0.0 U 100 0 0 eth0 [root@localhost ~]# ip route add default via 172.25.38.250 添加网关 [root@localhost ~]# route -n 查看网关 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 172.25.38.250 0.0.0.0 UG 0 0 0 eth0 172.25.0.0 0.0.0.0 255.255.0.0 U 100 0 0 eth0 [root@localhost ~]# vim /etc/resolv.conf 配置dns [root@localhost ~]# cat /etc/resolv.conf nameserver 114.114.114.114
