GitLab安装
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

2.2 登录
http://192.168.16.102 注意：这个地址是“external_url 'http://192.168.16.102'” 首次登录显示为密码设置界面，设置管理员密码，管理员账号默认username是root 设置完成之后，刷新即可使用root账号登录，登陆后会进入欢迎界面。
2.3 更新管理员资料
2.4 查看管理员面板
Admin Area的主面板显示整体数据，左侧导航菜单可以查看具体的分类信息
2.5 创建新用户
方式1：管理员直接创建用户
Admin Area ---》New user，根据规则和需要分别设置Account、Access部分，Password部分可以由本人进行设置。
查看邮箱，点击邮件中的链接，设置密码并登陆
方式2：用户直接注册新的账户
在GitLab登录界面，直接点击“Register”，添加用户相关信息。
3 - GitLab常用配置
3.1 配置Git存储仓库目录
默认存储目录为/var/opt/gitlab/git-data/repositories
[root@test102 ~]# ll /var/opt/gitlab/git-data/
total 0
drwxrws--- 3 git root 45 Nov 27 13:53
[root@test102 ~]#
如果要更新或增加存储仓库目录，可以修改/etc/gitlab/gitlab.rb配置文件中git_data_dirs部分的内容，然后执行“gitlab-ctl reconfigure”命令使之生效。 例如：
git_data_dirs({
"default" => {"path" => "/var/opt/gitlab/git-data"}
"newrepo" => {"path" => "/mnt/nfs-01/git-data"}
})
特别注意：
- 如果修改仓库目录，用户有权限访问，否则重新配置时会报错。
- 修改仓库目录后，必须将旧仓库的数据迁移到新目录下，否则相关项目会提示“没有仓库”。
sudo gitlab-ctl upgrade # 组件更新（可选）
sudo gitlab-ctl stop # 停止服务
sudo rsync -av <old-dir> <new-dir>/ # 目录同步（注意斜杠的作用）
ls <new-dir> # 检查文件及目录层级
sudo gitlab-ctl start # 启动服务
sudo gitlab-ctl reconfigure # 重配置
3.2 配置邮件SMTP
GitLab可以直接发送邮件，但如果内网对网络访问有限制，就需要配置内部的SMTP服务来发送邮件。
[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep smtp
559 ###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
560 ###! **Use smtp instead of sendmail/postfix.**
562 # gitlab_rails['smtp_enable'] = true
563 # gitlab_rails['smtp_address'] = "smtp.server"
564 # gitlab_rails['smtp_port'] = 465
565 # gitlab_rails['smtp_user_name'] = "smtp user"
566 # gitlab_rails['smtp_password'] = "smtp password"
567 # gitlab_rails['smtp_domain'] = "example.com"
568 # gitlab_rails['smtp_authentication'] = "login"
569 # gitlab_rails['smtp_enable_starttls_auto'] = true
570 # gitlab_rails['smtp_tls'] = false
574 # gitlab_rails['smtp_openssl_verify_mode'] = 'none'
576 # gitlab_rails['smtp_ca_path'] = "/etc/ssl/certs"
577 # gitlab_rails['smtp_ca_file'] = "/etc/ssl/certs/ca-certificates.crt"
[root@test102 ~]#
此外，也可以修改邮件的默认发送地址、显示名称等信息。
[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep gitlab_email
60 # gitlab_rails['gitlab_email_enabled'] = true
61 # gitlab_rails['gitlab_email_from'] = 'example@example.com'
62 # gitlab_rails['gitlab_email_display_name'] = 'Example'
63 # gitlab_rails['gitlab_email_reply_to'] = 'noreply@example.com'
64 # gitlab_rails['gitlab_email_subject_suffix'] = ''
65 # gitlab_rails['gitlab_email_smime_enabled'] = false
66 # gitlab_rails['gitlab_email_smime_key_file'] = '/etc/gitlab/ssl/gitlab_smime.key'
67 # gitlab_rails['gitlab_email_smime_cert_file'] = '/etc/gitlab/ssl/gitlab_smime.crt'

3.3 禁用创建组权限
GitLab默认所有的注册用户都可以创建组，在实际使用中，通常只会给指定的少部分用户相关权限。 将/etc/gitlab/gitlab.rb中的gitlab_rails['gitlab_default_can_create_group']参数设为false，然后重载配置即可。
[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep "create_group"
70 # gitlab_rails['gitlab_default_can_create_group'] = true
[root@test102 ~]#
3.4 集成OpenLDAP
设置/etc/gitlab/gitlab.rb文件中关于LDAP的内容，并重载配置，然后通过“gitlab-rake gitlab:ldap:check ”命令验证是否是否能正常获取用户列表，最后重启gitlab服务。
[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep "LDAP Settings"
