安装前准备

VMWare虚拟机
版本推荐CentOS7（我当前使用的版本是CentOS7）
配置好Linux的IP地址
保证Gitlab可用运行内存大于4G(否则虚拟机会变得非常消耗磁盘读写)
安装依赖软件

1	yum -y install policycoreutils openssh-server openssh-clients postfix

设置postfix开机自启，并启动，postfix支持gitlab发信功能

1	systemctl enable postfix && systemctl start postfix

安装GitLab

下载GitLab安装包

国内GitLab安装包地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/

我下载的是 11.3.3 版本，大家可以根据自己需求选择下载。

进入/usr/local/src/目录下载GitLab安装包

1	[root@localhost src]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.3.3-ce.0.el7.x86_64.rpm

安装GitLab安装包

[root@localhost src]# rpm -i gitlab-ce-11.3.3-ce.0.el7.x86_64.rpm 
warning: gitlab-ce-11.3.3-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY
It looks like GitLab has not been configured yet; skipping the upgrade script.

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

修改GitLab配置文件

修改GitLab配置文件指定服务器ip和自定义端口

1	vim /etc/gitlab/gitlab.rb

修改成如下(IP地址+端口号)：

1	external_url 'http://192.168.100.14:8801'

## Roles for multi-instance GitLab
##! The default is to have no roles enabled, which results in GitLab running as an all-in-one instance.
##! Options:
##!   redis_sentinel_role redis_master_role redis_slave_role geo_primary_role geo_secondary_role
##! For more deatils on each role, see:
