1 - GitLab安装
1.1 信息确认
[Anliven@node102 ~]$ uname -a
Linux node102 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[Anliven@node102 ~]$ cat /etc/system-release
CentOS Linux release 7.5.1804 (Core)
[Anliven@node102 ~]$
1.2 准备步骤
# 安装依赖
sudo yum install -y curl policycoreutils-python openssh-server postfix
# 启动SSH和postfix
sudo systemctl enable sshd
sudo systemctl start sshd
sudo systemctl enable postfix
sudo systemctl start postfix
# 开放端口
sudo firewall-cmd --add-service=ssh --permanent
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload
1.3 安装方式1：Yum
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install -y gitlab-ce
1.4 安装方式2：下载并安装rpm包
清华镜像：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/ 
注意：可以单独下载RPM包，然后上传到Server，要节约时间点。
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.5.0-ce.0.el7.x86_64.rpm
rpm -i gitlab-ce-12.5.0-ce.0.el7.x86_64.rpm
2 - 初始化配置
GitLab默认的配置文件路径：/etc/gitlab/
- /etc/gitlab/gitlab.rb：主配置文件，包含外部URL、仓库目录、备份目录等
- /etc/gitlab/gitlab-secrets.json：（执行gitlab-ctl reconfigure命令行后生成），包含各类密钥的加密信息
2.1 初始化配置
- 配置首页地址（需将设置的域名DNS解析到服务器IP，或者修改本地host将域名指向服务器IP）
- 修改服务端口，避免和其他服务端口冲突
- 重新配置并启动，使配置生效，并确认相关组件或进程的状态
- 设置账号密码和管理员信息
