环境

[root@iZ2851te7e5Z ~]# lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 7.1.1503 (Core)
Release:    7.1.1503
Codename:   Core

服务器安装了

• PHP7
• Nginx,占用80端口
• Mysql

安装

安装采用官网提供的安装方法.

进入页面 https://about.gitlab.com/downloads/

选择 CentOS 7

硬件要求

GitLab对硬件的要求不是很高,很显然,越好的硬件,越能支撑起更多的项目的和用户.

系统要求

支持的类UNIX系统

• Ubuntu
• Debian
• CentOS
• Red Hat Enterprise Linux (please use the CentOS packages and instructions)
• Scientific Linux (please use the CentOS packages and instructions)
• Oracle Linux (please use the CentOS packages and instructions)

不支持的类UNIX系统

• OS X
• Arch Linux
• Fedora
• Gentoo
• FreeBSD

不是类UNIX的系统

比如Windows,并不支持.

安装和配置必要的依赖关系

如果你安装postfix发送邮件，请选择“网站设置”中。而不是使用后缀也可以使用sendmail配置自定义SMTP服务器配置为SMTP服务器。

sudo yum install curl policycoreutils openssh-server openssh-clients
sudo systemctl enable sshd
sudo systemctl start sshd
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
sudo firewall-cmd --permanent --add-service=http
sudo systemctl reload firewalld

postfix 服务启动失败

 /usr/sbin/postconf: fatal: parameter inet_interfaces: no local interface found for ::1

修改配置文件 vi /etc/postfix/main.cf

修改的部分为

inet_interfaces = 127.0.0.1 #只能接受内部邮件，其它邮件不接受

inet_protocols = all

启动服务 sudo systemctl start postfix,成功.

安装firewalld

yum install firewalld

systemctl unmask firewalld

添加GitLab安装包到服务器

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

添加国内的镜像源

执行上面的命令,会一直 time out ,所以我们要换成国内的源.

以下操作针对CentOS 7 ,其他的请戳 https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce/

vim /etc/yum.repos.d/gitlab-ce.repo

[gitlab-ce]
name=gitlab-ce
baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
repo_gpgcheck=0
gpgcheck=0
enabled=1
gpgkey=https://packages.gitlab.com/gpg.key

注意,如果对应配置文件下有文件gitlab_gitlab-ce.repo,重命名一下,不然会默认加载这个导致上面的文件不起作用.

查看目前的yum进程,并杀死

 ps -a
  PID TTY          TIME CMD
18781 pts/0    00:00:00 sudo
18783 pts/0    00:00:00 bash
18796 pts/0    00:00:00 yum
18855 pts/0    00:00:00 sudo
18856 pts/0    00:00:00 yum
18871 pts/0    00:00:00 ps

kill -9 18796
kill -9 18856

sudo yum makecache
sudo yum install gitlab-ce 

上面执行完了,是这样的展示结果

sudo gitlab-ctl reconfigure

gitlab: GitLab should be reachable at http://iZ2851te7e5Z
gitlab: Otherwise configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
gitlab: And running reconfigure again.
gitlab: 
gitlab: For a comprehensive list of configuration options please see the Omnibus GitLab readme
gitlab: https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
gitlab: 
It looks like GitLab has not been configured yet; skipping the upgrade script.
  验证中      : gitlab-ce-8.7.6-ce.0.el7.x86_64                                                                                         1/1 

已安装:
  gitlab-ce.x86_64 0:8.7.6-ce.0.el7                                                                                                         

完毕！

配置和开始使用GitLab

sudo gitlab-ctl reconfigure

接下来会自动配置文件权限,安装数据库….

提示!安装的时间会很长!!!

根据我们服务器监控记录,配置过程花了5个小时!

修改配置文件 /etc/gitlab/gitlab.rb

目前的状态是完成了安装包的安装,但是还没有启用配置文件,所以依赖还都没有装。

所以非常不建议直接运行sudo gitlab-ctl reconfigure,不能再踩一次坑!QAQ

基本我们要调的东西都在/etc/gitlab/gitlab.rb里面,所以这个文件一定要仔细看好。

修改连接数据库为Mysql

因为我们本机已经用了LNMP做了环境,所以可以直接采用Mysql作为我们的数据库,而不用postgresql,减少服务器的负担。

企业版才支持使用mysql

查看状态

上面的命令是通过gitlab-ctl安装的,那么通过gitlab-ctl命令一样也能做别事情~

  hup
    Send the services a HUP.
  int
    Send the services an INT.
  kill

tail 查看日志

这个命令查看我们的gitlab在运行过程中有没有问题.

gitlab-ctl tail

后记

GitLab对服务器的要求比较高,文档上说4核8G,我的1核512M的小服务器在安装多次后卡死多次。我决定暂时先放放。。。以后再做这个。。。
