1、安装依赖项：yum -y install curl policycoreutils-python openssh-server openssh-clients
[root@izuf6fy69k7l7e20jogcj7z ~]# yum -y install curl policycoreutils-python openssh-server openssh-clients Loaded plugins: fastestmirror Determining fastest mirrors base | 3.6 kB 00:00:00 epel | 3.2 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/7): epel/x86_64/group_gz | 88 kB 00:00:00 (2/7): base/7/x86_64/group_gz | 166 kB 00:00:00 (3/7): extras/7/x86_64/primary_db | 156 kB 00:00:00 (4/7): epel/x86_64/updateinfo | 948 kB 00:00:00 (5/7): updates/7/x86_64/primary_db | 1.3 MB 00:00:00 (6/7): epel/x86_64/primary | 3.6 MB 00:00:00 (7/7): base/7/x86_64/primary_db | 6.0 MB 00:00:00 epel 12852/12852 Package openssh-server-7.4p1-16.el7.x86_64 already installed and latest version Package openssh-clients-7.4p1-16.el7.x86_64 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package curl.x86_64 0:7.29.0-46.el7 will be updated ......此处省略...... ---> Package libselinux-python.x86_64 0:2.5-14.1.el7 will be an update --> Finished Dependency Resolution Dependencies Resolved =========================================================================================================================================================================================== Package Arch Version Repository Size =========================================================================================================================================================================================== Installing: policycoreutils-python x86_64 2.5-29.el7 base 456 k Updating: ......此处省略...... nss-pem x86_64 1.0.3-5.el7 base 74 k policycoreutils x86_64 2.5-29.el7 base 916 k Transaction Summary =========================================================================================================================================================================================== Install 1 Package (+ 6 Dependent packages) Upgrade 1 Package (+10 Dependent packages) Total download size: 4.4 M Downloading packages: Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

2、重启SSHD服务并配置服务自启动（一般这一步可忽略）：systemctl restart sshd && systemctl enable sshd
[root@izuf6fy69k7l7e20jogcj7z ~]# systemctl restart sshd && systemctl enable sshd
一般情况使用Gitlab环境发送邮件服务功能都是直接使用其他外部SMTP服务器发送电子邮件方案，使用时配置外部SMTP服务器即可。所以Postfix邮件服务无需安装
3、下载Gitlab程序
[root@izuf6j9tjuw2zd5wodwiztz ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.1.4-ce.0.el7.x86_64.rpm --2018-08-20 15:29:43-- https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.1.4-ce.0.el7.x86_64.rpm Resolving mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)... 101.6.8.193, 2402:f000:1:408:8100::1 Connecting to mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)|101.6.8.193|:443... connected.

4、安装Gitlab程序：rpm -ivh gitlab-ce-11.1.4-ce.0.el7.x86_64.rpm
[root@izuf6j9tjuw2zd5wodwiztz ~]# rpm -ivh gitlab-ce-11.1.4-ce.0.el7.x86_64.rpm

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
5、编辑Gitlab配置文件（/etc/gitlab/gitlab.rb）定义访问地址参数external_url
## 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-external-url-for-gitlab external_url 'http://gitlab.ityww.cn'
6、重载Gitlab配置文件：gitlab-ctl reconfigure
Running handlers: Running handlers complete Chef Client finished, 429/613 resources updated in 02 minutes 35 seconds gitlab Reconfigured!
当出现以上提示时表示Gitlab重载配置文件顺利完成
7、根据实际地址访问Gitlab；初始访问Gitlab时需要初始化root管理员账户密码
