2. 安装Gitlab
（1）Gitlab提供了一个安装安装器，可以简化安装的一些步骤。 下载安装器，并执行脚本。
[root@c7201 ~]# curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
sudo gitlab-ctl reconfigureFor a comprehensive list of configuration options please see the Omnibus GitLab readme

3. 配置 Gitlab URL
cd /etc/gitlab/
vim gitlab.rb
改变gitlab服务器的外部域名
（2）执行下面命令让配置生效。
gitlab-ctl reconfigure
4. 配置防火墙
（1）开启防火墙
systemctl start firewalld
systemctl enable firewalld
(2)开放所需服务，如下是开通ssh, http,https服务.
[root@c7201 gitlab]# firewall-cmd --permanent --add-service ssh
success
[root@c7201 gitlab]# firewall-cmd --permanent --add-service http
success
[root@c7201 gitlab]# firewall-cmd --permanent --add-service https
success[root@c7201 gitlab]# firewall-cmd --reload
success
(3)校验开通了哪些服务，使用以下命令
[root@c7201 gitlab]# firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
interfaces: ens33
sources:
services: ssh dhcpv6-client http https
ports:
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
4. 执行基本配置
（1）设置密码
（2）进行登陆，默认的用户名是root.
(3) 点击如下图所示，更改个人信息。
