（一）GitLab安装
1.安装并配置必要的依赖项
在CentOS 7（和RedHat / Oracle / Scientific Linux 7）上，以下命令还将在系统防火墙中打开HTTP和SSH访问
[root@docker01 ~]# yum install -y curl policycoreutils-python openssh-server

软件包 curl-7.29.0-51.el7.x86_64 已安装并且是最新版本
软件包 policycoreutils-python-2.5-29.el7_6.1.x86_64 已安装并且是最新版本
软件包 openssh-server-7.4p1-16.el7.x86_64 已安装并且是最新版本
无须任何处理
[root@docker01 ~]# systemctl enable sshd
[root@docker01 ~]# systemctl start sshd
[root@docker01 ~]# firewall-cmd --permanent --add-service=http
success
[root@docker01 ~]# systemctl reload firewalld
关闭selinux防火墙
[root@docker01 ~]# vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are prote
cted.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
重启生效
[root@docker01 ~]# reboot
下载安装文件
安装文件也可去国内源网站，速度更快。
清华大学开源软件镜像站

此次下载稳定版gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm
2.安装GitLab
使用ftp工具将安装文件上传到当前目录
[root@docker01 ~]# rpm -ivh gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm
警告：gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm: 头V4 RSA/SHA1 Signature, 密钥 ID f27eab47: NOKEY

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 reconfigure
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
（1）修改配置文件
[root@docker01 ~]# vi /etc/gitlab/gitlab.rb
## GitLab URL
##! URL on which GitLab will be reachable.
##! For more details on configuring external_url see:
##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-ex
ternal-url-for-gitlab
external_url 'http://gitlab.example.com'修改为
external_url 'http://192.168.32.128'
更改配置文件后需重新配置（等待时间较长）
[root@docker01 ~]# gitlab-ctl reconfigure
