centos7.4+GitLab部署

GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭建起来的web服务。

建议：内存4G以上不然带不动

#yum源更新，重启系统

[[email protected] ~]# yum update && reboot

#安装相应工具

[[email protected] ~]yum install curl policycoreutils openssh-server openssh-clients postfix -y
[[email protected] ~]systemctl start postfix

#新建GitLab源

[[email protected] ~]# vim /etc/yum.repos.d/gitlab-ce.repo

[[email protected] ~]# yum makecache
[[email protected] ~]# yum install -y gitlab-ce

#安装git工具

[[email protected] ~]# yum install git -y

通常我们在部署的时候会发现80和8080端口均被占用，那么我们就需要修改gitlab的默认端口。
#gitlab配置文件路径，用于gitlab如何调用80和8080的服务等。

/etc/gitlab/gitlab.rb

编辑配置文件并找到 unicorn 配置，将端口修改成想要的端口
修改/etc/gitlab/gitlab.rb

vim /etc/gitlab/gitlab.rb

#unicorn[‘port‘] = 8080 修改 8070  默认是注释的去掉前面的#
unicorn[‘port‘] = 8070
#nginx[‘listen_port‘] = nil 修改 8090  默认是注释的去掉前面的#
nginx[‘listen_port‘] = 8090

修改/var/opt/gitlab/gitlab-rails/etc/unicorn.rb

vim /var/opt/gitlab/gitlab-rails/etc/unicorn.rb

#listen "127.0.0.1:8080", :tcp_nopush => true
listen "127.0.0.1:8070", :tcp_nopush => true

修改默认的gitlab nginx的web服务80端 /var/opt/gitlab/nginx/conf/gitlab-http.conf

vim /var/opt/gitlab/nginx/conf/gitlab-http.conf

#listen *:80;
listen *:8090;

#加载配置文件并启动，时间稍长

[[email protected] ~]# gitlab-ctl reconfigure

#gitlab-ctl其他命令

启动：gitlib-ctl start
关闭：gitlab-ctl stop
重启：gitlab-ctl restart
重载配置：gitlab-ctl reconfigure
查看状态：gitlab-ctl status

#查看端口保证80端口不被占用

[[email protected] ~]# lsof -i:80
COMMAND PID       USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   700       root    7u  IPv4  16903      0t0  TCP *:http (LISTEN)
nginx   804 gitlab-www    7u  IPv4  16903      0t0  TCP *:http (LISTEN)

浏览器登录gitlab，输入http://服务器ip:配置的nginx端口，进入下图：

设置一个密码后，使用 root 用户进行登录。

新建一个项目

那么我们怎样为 GitLab 的账号添加 SSH keys 呢
1).首先打开 linux 服务器，输入命令：ls -al ~/.ssh，检查是否显示有 id_rsa.pub 或者 id_dsa.pub 存在，如果存在请直接跳至第3步。

2).在 bash 中输入 ssh-keygen -t rsa -C ”[email protected]” ,注意这个地方的邮箱地址地址替换成你自己的邮箱地址即可，在显示如下的输出后一直按回车即可：

[[email protected] ~]# useradd web-gitlab
[[email protected] ~]# su !$
su web-gitlab
[[email protected] root]$
[[email protected] root]$
[[email protected] root]$ ssh-keygen -t rsa -C ”[email protected]”
Generating public/private rsa key pair.
Enter file in which to save the key (/home/web-gitlab/.ssh/id_rsa):
Created directory ‘/home/web-gitlab/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/web-gitlab/.ssh/id_rsa.
Your public key has been saved in /home/web-gitlab/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:hwumGaUbZy7pD/R1LmaRC4NV42NToJZIuqsv1CMyhuo ”[email protected]”
The key‘s randomart image is:
+---[RSA 2048]----+
|    .   +..      |
|   o . = o       |
|  . . * =        |
|   . * . =       |
|. o * B S o      |
|++ = & = B       |
|=.o O o * .      |
|o. . o o .       |
|oE. ...          |
+----[SHA256]-----+
[[email protected] root]$ 

在这里可以看到 id_rsa 和 id_rsa.pub 已经生成，并且生成的路径为 /home/web-gitlab/.ssh/。

[[email protected] root]$ cd /home/web-gitlab/
[[email protected] ~]$
[[email protected] ~]$
[[email protected] ~]$ ll
total 0
[[email protected] ~]$
[[email protected] ~]$ ll .ssh/
total 8
-rw------- 1 web-gitlab web-gitlab 1679 Apr 28 10:42 id_rsa
-rw-r--r-- 1 web-gitlab web-gitlab  402 Apr 28 10:42 id_rsa.pub

3).打开 id_rsa.pub 文件，并且复制全部内容。

[[email protected] ~]$ cat .ssh/id_rsa.pub 

4).打开 GitLab 账户，添加 SSH Keys:

这样就添加了一个SSH key。
5).完成上面的步骤之后就可以使用ssh来连接GitLab，并进行相应的操作了。
我们可以通过 ssh 来 clone 项目

[[email protected] ~]# su web-gitlab
[[email protected] root]$
[[email protected] root]$ cd /home/web-gitlab/
[[email protected] ~]$ git clone [email protected]服务器IP:root/test-demo.git

[[email protected] ~]$
[[email protected] ~]$ ll

drwxrwxr-x 3 web-gitlab web-gitlab 4096 Apr 28 11:03 test-demo

这就是我们通过 ssh 克隆下来的项目。
