首先准备实验环境
| 虚拟机 | 主机名 | IP地址 | 服务 | 系统版本 | 内核版本 |
| Vmware Workstation 14 | gitlab.example.com | 192.168.244.130 | gitlab | CentOS Linux release 7.5.1804 (Core) | 3.10.0-862.el7.x86_64 |
| jenkins.example.com | 192.168.244.131 | jenkis | |||
| ansible.example.com | 192.168.244.132 | asible |
除此之外，还要在宿主机win10系统下的C:\Windows\System32\drivers\etc\hosts文件中添加如下内容
192.168.244.130 gitlab.example.com 192.168.244.131 jenkins.example.com 192.168.244.132 ansible.example.com
关闭防火墙和selinux
[root@gitlab ~]# sed -i "s/enforcing/disabled/" /etc/selinux/config [root@gitlab ~]# systemctl stop firewalld && systemmctl disable firewalld [root@gitlab ~]# reboot [root@gitlab ~]# getenforce Permissive [root@server01 ~]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1)
安装postfix并启动
[root@gitlab ~]# yum install postfix [root@gitlab ~]# systemctl start postfix && systemctl enable postfix
安装Gitlab组件及gitlab-ce
[root@gitlab ~]# yum install curl policycoreutils openssh-server openssh-clients [root@gitlab ~]# curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash [root@gitlab ~]# yum install -y gitlab-ce
也可以去https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm安装方法。
证书创建与配置加载
[root@gitlab ~]# mkdir -p /etc/gitlab/ssl 创建私有密钥 [root@gitlab ~]# openssl genrsa -out "/etc/gitlab/ssl/gitlab.example.com.key" 2048 Generating RSA private key, 2048 bit long modulus ...............+++ ...............................................................................+++ e is 65537 (0x10001) 创建私有证书 [root@gitlab ~]# openssl req -new -key "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.csr" You are about to be asked to enter information that will be incorporated into your certificate request.

配置gitlab
[root@gitlab ~]# cp /etc/gitlab/gitlab.rb{,.bak} [root@gitlab ~]# vim /etc/gitlab/gitlab.rb ## 更改如下 13 external_url 'https://gitlab.example.com' 13行左右 952 nginx['redirect_http_to_https'] = true 964 nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.example.com.crt" 965 nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.example.com.key" 979 # nginx['ssl_dhparam'] = /etc/gitlab/ssl/dhparam.pem # Path to dhparams.pem, eg. /etc/gitlab/ssl/dhparams.pem
初始化gitlab相关服务配置
[root@gitlab ~]# gitlab-ctl reconfigure Starting Chef Client, version 13.6.4 resolving cookbooks for run list: ["gitlab"] Synchronizing Cookbooks: - gitlab (0.0.1) - package (0.1.0) - postgresql (0.1.0) - redis (0.1.0) - mattermost (0.1.0) - registry (0.1.0) - gitaly (0.1.0) - consul (0.0.0) - nginx (0.1.0) - runit (0.14.2) - letsencrypt (0.1.0) - acme (3.1.0) - crond (0.1.0) - compat_resource (12.19.0) Installing Cookbook Gems: Compiling Cookbooks...

对nginx配置
[root@gitlab ~]# cp /var/opt/gitlab/nginx/conf/gitlab-http.conf{,.bak} [root@gitlab ~]# vim /var/opt/gitlab/nginx/conf/gitlab-http.conf 37 server_name gitlab.example.com; #在此行下面添加38行的内容 38 rewrite ^(.*)$ https://$host$1 permanent;
重启gitlab
[root@gitlab ~]# gitlab-ctl restart ok: run: alertmanager: (pid 6526) 1s ok: run: gitaly: (pid 6543) 0s ok: run: gitlab-monitor: (pid 6556) 0s ok: run: gitlab-workhorse: (pid 6579) 1s ok: run: logrotate: (pid 6589) 0s ok: run: nginx: (pid 6597) 1s ok: run: node-exporter: (pid 6681) 0s ok: run: postgres-exporter: (pid 6687) 1s ok: run: postgresql: (pid 6698) 0s ok: run: prometheus: (pid 6706) 0s ok: run: redis: (pid 6722) 0s ok: run: redis-exporter: (pid 6856) 0s ok: run: sidekiq: (pid 6866) 0s ok: run: unicorn: (pid 6880) 0s # 可以看出gitlab的所有服务重启完成
使用宿主机win10下的chrome浏览器访问gitlab.example.com:80
开始使用gitlab
创建一个测试工程
复制仓库地址
回到win10宿主机，重新打开一个git命令行窗口如下所示操作
# 粘贴仓库地址回车后会弹出输入账户和密码的窗口
之后就会将空的测试仓库克隆到本地宿主机的桌面上的repo目录下
xueji@xueji MINGW64 ~/Desktop/repo $ git -c http.sslVerify=false clone https://gitlab.example.com/root/test-repo.git Cloning into 'test-repo'... warning: You appear to have cloned an empty repository. xueji@xueji MINGW64 ~/Desktop/repo $ pwd /c/Users/xueji/Desktop/repo xueji@xueji MINGW64 ~/Desktop/repo $ ls test-repo/ xueji@xueji MINGW64 ~/Desktop/repo $ ls test-repo/
在win10宿主机下的test-repo目录下新建一个test.py文件，并上传至gitlab
xueji@xueji MINGW64 ~/Desktop/repo $ cd test-repo/ xueji@xueji MINGW64 ~/Desktop/repo/test-repo (master) $ vi test.py xueji@xueji MINGW64 ~/Desktop/repo/test-repo (master) $ git add . warning: LF will be replaced by CRLF in test.py.

Please make sure you have the correct access rights and the repository exists. xueji@xueji MINGW64 ~/Desktop/repo/test-repo (master)
报错，跟据提示信息我们进行如下操作

回到gitlab的浏览器页面，刷新查看
已经成功上传到test-repo工程当中。
Gitlab应用
比如说Systeminfo
比如说日志
需要我们关注的是application.log和production.log两项
比如说健康状况
创建开发人员及leader的账号
开发人员账号
其他选项不要动，点击创建即可。
创建leader的账号
其他也不要动。
建好后的账户
同理添加lead账户
更改两个账户的密码
其他选项保持不变，然后点击页面最下面的save changes，同理更改lead的密码
使用dev账户进行git命令行的提交操作

返回gitlab的浏览器页面
使用开发账户登录
设置新密码
至此，gitlab安装配置完成，接下来演示gitlab应用：
开发人员创建一个分支，然后发申请到主管请求合并到主分支，
回到gitbash命令行，首先删除之前的test-repo目录：
然后使用dev账号登陆gitlab，并复制gitlab仓库地址：
本地提交并推送到gitlab远端：
开始提交合并到主分支的申请
接着退出当前的dev账号，使用lead账号登录，同样lead账号首次登录需要更改密码，步骤同dev一样：
jenkins的配置与使用见Jenkins+Gitlab+Ansible自动化部署(二)。
