CenterOS7手动安装gitlab

1.准备工作

gitlab的安装，需要依赖相关组件，主要有

policycoreutils-python
openssh
postfix

实测默认的centerOS7上都已经安装了

1.1 检查policycoreutils-python是否安装

[root@localhost .jenkins]# rpm -qa|grep policycoreutils-python
policycoreutils-python-2.5-34.el7.x86_64

1.2 检查openssh是否安装

[root@localhost .jenkins]# rpm -qa|grep openssh
openssh-clients-7.4p1-23.el7_9.x86_64
openssh-7.4p1-23.el7_9.x86_64
openssh-server-7.4p1-23.el7_9.x86_64

1.3 检查postfix是否安装

[root@localhost .jenkins]# rpm -qa|grep postfix
postfix-2.10.1-9.el7.x86_64

2.下载gitlab安装包

从gitlab官网地址中下载：https://packages.gitlab.com/gitlab/gitlab-ce，选择适用于CentOS7的el/7版本进行下载。

wget --content-disposition https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-16.6.8-ce.0.el7.x86_64.rpm/download.rpm

镜像站下载地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-17.1.1-ce.0.el7.x86_64.rpm

3.安装gitlab

rpm -i gitlab-ce-17.1.1-ce.0.el7.x86_64.rpm

当出现以下内容提示，说明gitlab安装成功；

warning: gitlab-ce-17.1.1-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

Help us improve the installation experience, let us know how we did with a 1 minute survey:
https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=17-1

4.修改对外暴露的IP及端口

修改/etc/gitlab/gitlab.rb文件中的external_url，设置gitlab的登录地址；

vim /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-external-url-for-gitlab
##!
##! Note: During installation/upgrades, the value of the environment variable
##! EXTERNAL_URL will be used to populate/replace this value.
##! On AWS EC2 instances, we also attempt to fetch the public hostname/IP
##! address from AWS. For more details, see:
##! https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html
external_url 'http://192.168.124.17:8080'

重新加载配置

gitlab-ctl reconfigure     #重新生成相关配置文件，执行此命令时间比较长

5.启动GitLab

# 关闭防火墙 也可以自行开放端口
systemctl stop firewalld   

# 开放端口号
firewall-cmd --zone=public --add-port=8080/tcp --permanent
# 重启防火墙
systemctl restart firewalld

# 重启gitlab
gitlab-ctl restart

访问测试:http://192.168.124.17:8080

502问题定位：端口冲突导致的

vim /etc/gitlab/gitlab.rb

找到如下内容

### Advanced settings
# puma['listen'] = '127.0.0.1'
# puma['port'] = 8080
# puma['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
# puma['somaxconn'] = 2048

修改为

### Advanced settings
puma['listen'] = '127.0.0.1'
puma['port'] = 8008
# puma['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
# puma['somaxconn'] = 2048

重新配置启动

#重新生成相关配置文件，执行此命令时间比较长
gitlab-ctl reconfigure 
# 重启gitlab
gitlab-ctl restart

再次访问测试：http://192.168.124.17:8080/

6. 配置gitlab开机自动启动

systemctl enable gitlab-runsvdir.service
systemctl start gitlab-runsvdir.service
# 关闭gitlab的自动启动命令：
systemctl disable gitlab-runsvdir.service
