一、 安装并配置必要的依赖关系
在CentOS系统上安装所需的依赖：ssh，防火墙,postfix(用于邮件通知) ，wget，以下这些命令也会打开系统防火墙中的HTTP和SSH端口访问。
1.安装ssh
[root@defaultStart41 ~]# sudo yum install -y curl policycoreutils-pythonopenssh-server
... ...
Updated:
curl.x86_64 0:7.29.0-59.el7_9.1
Dependency Updated:
libcurl.x86_64 0:7.29.0-59.el7_9.1 libssh2.x86_64 0:1.8.0-4.el7
Complete!
[root@defaultStart41 ~]#
2.将SSH服务设置成开机自启动，安装命令：sudo systemctl enable sshd
3.启动SSH服务，安装命令：sudo systemctl start sshd
[root@defaultStart41 ~]# sudo systemctl enable sshd
[root@defaultStart41 ~]# sudo systemctl start sshd
[root@defaultStart41 ~]#
4。安装防火墙（如果已经安装了防火墙并且已经在运行状态，则可直接进行第6步）
yum install firewalld systemd -y
[root@defaultStart41 ~]# yum install firewalld systemd -y
...
...
Updated:
firewalld.noarch 0:0.6.3-13.el7_9 systemd.x86_64 0:219-78.el7_9.3
Dependency Updated:
firewall-config.noarch 0:0.6.3-13.el7_9 firewalld-filesystem.noarch 0:0.6.3-13.el7_9 libgudev1.x86_64 0:219-78.el7_9.3 python-firewall.noarch 0:0.6.3-13.el7_9
systemd-libs.x86_64 0:219-78.el7_9.3 systemd-python.x86_64 0:219-78.el7_9.3 systemd-sysv.x86_64 0:219-78.el7_9.3
Complete!
5.开启防火墙，安装命令：service firewalld start
[root@defaultStart41 ~]# service firewalld start
Redirecting to /bin/systemctl start firewalld.service
[root@defaultStart41 ~]#
6.添加http服务到firewalld,pemmanent表示永久生效，若不加--permanent系统下次启动后就会失效。
sudo firewall-cmd --permanent --add-service=http
[root@defaultStart41 ~]# sudo firewall-cmd --permanent --add-service=http
success
[root@defaultStart41 ~]#
7.重启防火墙，安装命令：sudo systemctl reload firewalld
[root@defaultStart41 ~]# sudo systemctl reload firewalld
[root@defaultStart41 ~]#
8.接下来，安装Postfix以发送通知邮件，安装命令：sudo yum install postfix
注意：有个提示y/n ,需要输入y
在安装Postfix期间，可能会出现配置屏幕。选择“Internet Site”并按enter键。使用您的服务器的外部DNS以“mail name”并按enter。如果出现额外的屏幕，继续按enter键接受默认值。
[root@defaultStart41 ~]# sudo yum install postfix
...
...

Updating : 2:postfix-2.10.1-9.el7.x86_64 1/2
Cleanup : 2:postfix-2.10.1-7.el7.x86_64 2/2

Updated:
postfix.x86_64 2:2.10.1-9.el7
Complete!
[root@defaultStart41 ~]#
9.将postfix服务设置成开机自启动，安装命令：sudo systemctl enable postfix
10.启动postfix，安装命令：sudo systemctl start postfix
[root@defaultStart41 ~]# sudo systemctl enable postfix
[root@defaultStart41 ~]# sudo systemctl start postfix
[root@defaultStart41 ~]#
11.wget 用于从外网上下载插件
检查系统中是否已经安装wget，使用命令若出现下图wget相关版本描述则说明系统中已经安装wget 若报系统找不到命令说明wget未安装
若wget未安装则进行安装，安装命令：yum -y install wget
[root@defaultStart41 ~]# clear
[root@defaultStart41 ~]# wget -V
GNU Wget 1.14 built on linux-gnu.

[root@defaultStart41 ~]#
12.安装vim编辑器 安装命令：yum install vim -y
[root@defaultStart41 ~]# yum install vim -y
...
...
Updated:
vim-enhanced.x86_64 2:7.4.629-8.el7_9
Dependency Updated:
vim-common.x86_64 2:7.4.629-8.el7_9
Complete!
[root@defaultStart41 ~]#
二、添加GitLab镜像源并安装gitlab服务器
1.添加gitlab镜像
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm
[root@defaultStart41 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm
--2021-07-29 08:29:24-- https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm

[root@defaultStart41 ~]#
2.安装gitlab 安装命令：rpm -i gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm
安装过程需要些时间，如果出现下图，则说明安装成功。
[root@defaultStart41 ~]# rpm -i gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm
warning: gitlab-ce-10.0.0-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
[root@defaultStart41 ~]#
4.修改gitlab配置文件指定服务器ip和自定义端口：
vim /etc/gitlab/gitlab.rb
external_url 'http://gitlab.example.com'
修改为
external_url 'http://192.168.121.41:8080'
进入编辑器后按“i”键进入编辑状态，ESC键退出编辑状态
退出并保存，命令输入“:wq”
ps:注意这里设置的端口不能被占用，默认是8080端口，如果8080已经使用，请自定义其它端口，并在防火墙设置开放相对应得端口
5.重置并启动GitLab
执行：
gitlab-ctl reconfigure
大概3分钟时间
[root@defaultStart41 ~]# gitlab-ctl reconfigure
...
...
Recipe: gitlab::postgres-exporter
* service[postgres-exporter] action restart
- restart service service[postgres-exporter]
* ruby_block[reload postgres-exporter svlogd configuration] action create
- execute the ruby block reload postgres-exporter svlogd configuration
Running handlers:
Running handlers complete

gitlab Reconfigured!
[root@defaultStart41 ~]# gitlab-ctl restart
提示 "ok: run:"表示启动成功
[root@defaultStart41 ~]#
[root@defaultStart41 ~]# gitlab-ctl restart

[root@defaultStart41 ~]#
6.访问 GitLab页面
如果没有域名，直接输入服务器ip和指定端口进行访问
初始账户: root 密码:5iveL!fe
没有显示
lsof -i:8080 看到8080 被 两个程序占用
[root@defaultStart41 ~]# lsof -i:8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 39749 root 7u IPv4 262144 0t0 TCP *:webcache (LISTEN)
nginx 39786 gitlab-www 7u IPv4 262144 0t0 TCP *:webcache (LISTEN)
[root@defaultStart41 ~]# netstat -tunlp | grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 39749/nginx: master
[root@defaultStart41 ~]#
参考文章
---https://www.runoob.com/w3cnote/linux-check-port-usage.html3. 重新配置端口
配置gitlib的IP和端口
vi /etc/gitlab/gitlab.rb 进入gitlab.rb修改IP和端口：进入编辑器后按“i”键进入编辑状态，ESC键退出编辑状态，退出并保存，命令输入“:wq”
[root@defaultStart41 ~]# vim /etc/gitlab/gitlab.rb
如果8080端口被别的服务占用可以改成8081 8082等，如果开启额防火墙，需要把相应的端口放开：例如：firewall-cmd --zone=public --add-port=8080/tcp --permanent
external_url 'http://192.168.121.41:8081'
改用8081 端口，
[root@defaultStart41 ~]# firewall-cmd --zone=public --add-port=8081/tcp --permanent
success
[root@defaultStart41 ~]#
重置并启动GitLab
配置：gitlab-ctl reconfigure
大概2,3 分钟配置
[root@defaultStart41 ~]# gitlab-ctl reconfigure
...
...
...
Recipe: gitlab::gitlab-rails
* execute[clear the gitlab-rails cache] action run
- execute /opt/gitlab/bin/gitlab-rake cache:clear
Recipe: gitlab::unicorn
* service[unicorn] action restart
- restart service service[unicorn]
Recipe: gitlab::sidekiq
* service[sidekiq] action restart
- restart service service[sidekiq]
Recipe: gitlab::nginx
* service[nginx] action restart
- restart service service[nginx]

虚拟机可以访问 实体机不可以访问 gitLab
访问gitlib
1、外部系统是win10
2、虚拟机地址：192.168.121.41，主机地址：10.147.228.92
问题一：在主机上不能通过http://192.168.121.41:8081来访问虚拟机中的Web服务器
https://www.cnblogs.com/yaomajor/p/8538999.html
解决方法：
1、切换到root用户
2、在终端内输入以下两条命令
iptables -F
iptables -P INPUT ACCEPT（设置默认允许规则）
实体机访问web
访问gitlib
在浏览器输入刚才设置的IP和端口号（http://192.168.121.41:8081） 就可以访问的gitlib页面，初始账户: root 密码:5iveL!fe。登录之后就可以创建远程项目了
root: 5iveL!fe
weilei:12346578
暂时都访问不了 20210730
root: 12345678
weilei: 12345678
