Gitlab是一个用Ruby on Rails开发的开源项目管理程序.可以通过WEB界面进行访问公开的或者私人项目. 它和Github有类似的功能,能够浏览源代码,管理缺陷和注释.

本文选择NGINX与MYSQL来配合GitLab实现web管理,数据存储等功能,配置过程中难点基本在GitLab的脚本修改,SSH秘钥连接,Nginx SSL证书等这些方面,作者也是耗费非常大的力气,结合很多文档的clue以及很多老外的debug comment,终于最终完成,希望在此给大家一个抛砖引玉的机会,了解到SCM(软件配置管理)其实也不是想象中那么小儿科,很多逻辑也着实需要下功夫investigation.

最后我是一路向北,我为我自己带盐....

解决方案:

环境部署

操作系统               centos6.3 x64

GitLab                   GitLab 6-3-stable

GitLab Shell           1.8.0

Ruby                     2.0.0p353

NGINX                  nginx-1.4.0

MYSQL                 mysql-5.6.10

         

server端配置:

Git server(centos6.3 x64): git.example.com
Git client(centos6.3 x64): client.example.com

一.安装前的准备工作

1.关闭iptables和SELINUX

# service iptables stop

# setenforce 0

# vi /etc/sysconfig/selinux

---------------

SELINUX=disabled

---------------

2.同步时间

# ntpdate cn.pool.ntp.org

3.安装LNMP

传送门:http://www.showerlee.com/archives/73


4.安装GitLab的所需依赖包和工具

# su -
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-5-4.noarch.rpm
# yum -y groupinstall 'Development Tools'
# yum -y install vim-enhanced readline readline-devel ncurses-devel gdbm-devel glibc-devel tcl-devel openssl-devel curl-devel expat-devel db4-devel byacc sqlite-devel gcc-c++ libyaml libyaml-devel libffi libffi-devel libxml2 libxml2-devel libxslt libxslt-devel libicu libicu-devel system-config-firewall-tui python-devel redis sudo wget crontabs logwatch logrotate perl-Time-HiRes git

5.配置redis

配置redis开机启动:

# chkconfig redis on
# service redis start
 
 6.更改gem源(若默认无法连接)
 a.显示当前使用的sources
# gem sources
 
 b.删除缺省source
# gem sources -r http://rubygems.org/
 
 c.添加一个source
# gem sources -a https://ruby.taobao.org
 
 d.更新source cache
# gem sources -u
 
 6.安装Ruby
 
 a.源码安装Ruby
传送门: http://www.showerlee.com/archives/1123
 
 b.安装bundle组件:
# gem install bundler --no-ri --no-rdoc
 
二.安装GITLab shell
 
 1.创建用户git
# su -
# adduser --system --shell /bin/bash --comment 'GitLab' --create-home --home-dir /home/git/ git
 
 2、配置GitLab shell
 GitLab shell是专门为GitLab开发的提供ssh访问和版本管理的软件。
 a.使用git账户登陆
# su - git
 
 b.克隆gitlab shell
# git clone https://github.com/gitlabhq/gitlab-shell.git
 
 c.切换成1.8.0版本,并编辑配置
# cd gitlab-shell
# git checkout v1.8.0
 
 d.拷贝配置文件
# cp config.yml.example config.yml
# vi config.yml
—————————————————————————————————————————
# 将gitlab_url修改成gitlab的访问域名。例如本文档:https://git.example.com/
gitlab_url: "https://git.example.com"
# 将self_signed_cert修改成 true
self_signed_cert: true
# 添加网站SSL证书 
ca_file: "/usr/local/nginx/ssl/gitlab.crt"
 —————————————————————————————————————————
注:如果gitlab是使用http访问,则需将https替换成http,配置文件中的self_signed_cert要修改成false,否则gitlab shell在通过api和gitlab进行通信的时候就会出现错误,导致项目push出错。因为后面配置web服务器的时候是使用ssl,所以这里要按照ssl的方式配置。
另外本文档的域名为测试域名,不要忘记在C/S两端均做好域名映射。
 
 e.安装一些需要的目录和文件
# ./bin/install
 
 5、配置MySQL数据库(安装过程详见上文)
 a.登录数据库
# mysql -u root -p
 
 b. 为gitlab创建使用用户
> create user gitlab@'localhost' identified by '123456';
 
 c.创建gitlaba使用的数据库
> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
 
 d.给予gitlab用户权限
> GRANT SELECT, LOCK TABLES, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';

三.安装GitLab

1.将GitLab安装在git的家目录下:

# su - git
 
 2.克隆GitLab并切换分支到6-3-stable
a.克隆GitLab
# git clone https://github.com/gitlabhq/gitlabhq.git gitlab
 
 b. 切换到6-3-stable分支
# cd /home/git/gitlab
# git checkout 6-3-stable
 
 c、配置项目
a.复制配置文件
# cp config/gitlab.yml.example config/gitlab.yml
 
 b.修改配置文件中的访问域名
# sed -i 's|localhost|git.example.com|g' config/gitlab.yml
 
 d.设定log和tmp目录所有者和权限
# chown -R git log/
# chown -R git tmp/
# chmod -R u+rwX log/
# chmod -R u+rwX tmp/
 
 e.创建gitlab-satellites目录
# mkdir /home/git/gitlab-satellites
 
 f.创建tmp/pids/和tmp/sockets/目录,确保gitlab有相应的权限
# mkdir tmp/pids/
# mkdir tmp/sockets/
# chmod -R u+rwX tmp/pids/
# chmod -R u+rwX tmp/sockets/
 
 g.创建public/uploads目录
# mkdir public/uploads
# chmod -R u+rwX public/uploads
 
 h.复制unicorn配置
# cp config/unicorn.rb.example config/unicorn.rb

i.保持unicorn配置文件默认配置

g.配置git的用户和邮件

# git config --global user.name "GitLab"
# git config --global user.email "gitlab@git.example.com”
# git config --global core.autocrlf input

k.配置数据库访问文件

# cp config/database.yml.mysql config/database.yml
 编辑config/database.yml,设置其中连接数据库的账号密码
# vi config/database.yml
———————————————————————————————————
#
# PRODUCTION
#
production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: gitlabhq_production
  pool: 10
gitlab
123456”
  # host: localhost
  # socket: /tmp/mysql.sock

———————————————————————————————————

修改其中username和password就可以了,其中密码就是上面数据库步骤中创建gitlab用户的密码。

l.确保该文件只有git账号有权限读取。

# chmod o-rwx config/database.yml
 
四.安装Gems
 
 1.安装charlock_holmes
# su -
# gem install charlock_holmes --version '0.6.9.4'
# exit
 
 2.安装mysql包
# cd /home/git/gitlab/
# vi Gemfile 
修改 https://rubygems.org 为 https://ruby.taobao.org
 
 # bundle install --deployment --without development test postgres puma aws
若报Could not find modernizr-2.6.2 in any of the sources错误,没有则无视:

修复方案:

# vi Gemfile

搜索该行   gem "modernizr",        "2.6.2"

更改为:   gem "modernizr-rails",  "2.7.1"

# vi Gemfile.lock

搜索该行   modernizr (2.6.2)

更改为:   modernizr-rails (2.7.1)

搜索该行   modernizr (= 2.6.2):

更改为:   modernizr-rails (= 2.7.1)

重新执行

# bundle install --deployment --without development test postgres puma aws
 
 3.初始化数据和激活高级功能
# cd /home/git/gitlab
# bundle exec rake gitlab:setup RAILS_ENV=production
这步完成后,会生一个默认的管理员账号/密码:
admin@local.host/5iveL!fe

4.安装启动脚本

# su -
# wget -O /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlab-recipes/5-0-stable/init.d/gitlab
# chmod +x /etc/init.d/gitlab

5.开机时启动

# chkconfig --add gitlab
# chkconfig gitlab on
 
 6.检测应用程序状态
# su - git
# cd gitlab/
# bundle exec rake gitlab:env:info RAILS_ENV=production
# exi

t

可以查看到系统、Ruby、GitLab和GitLab Shell的版本和其他信息。

7.启动GitLab实例

# service gitlab start

8.查看应用更加详细的信息

# su - git
# cd gitlab/
 # bundle exec rake gitlab:check RAILS_ENV=production
这里会提示一个Init script up-to-date的错误,如下:
——————————————————————————————————————————————————
Init script up-to-date? ... no
Try fixing it:
Redownload the init script
For more information see:
doc/install/installation.md in section "Install Init Script"
Please fix the error above and rerun the checks.

——————————————————————————————————————————————————

查阅官方自带文档,说明此问题可忽略.

五.Nginx配置

1.配置Gitlab虚拟主机及SSL连接:

# cd /usr/local/nginx/conf/vhosts/
# vi gitlab-ssl.conf
注: 这里先感谢提供此脚本的极客,该脚本在原基础上稍作改动.
内容用红字标注的地方为需要自定义的地方.

##################################
##        CHUNKED TRANSFER      ##
##################################
##
## It is a known issue that Git-over-HTTP requires chunked transfer encoding [0]
## which is not supported by Nginx < 1.3.9 [1]. As a result, pushing a large object
## with Git (i.e. a single large file) can lead to a 411 error. In theory you can get
## around this by tweaking this configuration file and either:
## - installing an old version of Nginx with the chunkin module [2] compiled in, or
 ## - using a newer version of Nginx.
 ##
## At the time of writing we do not know if either of these theoretical solutions works. As a workaround
## users can use Git over SSH to push large files.

2.将nginx加入git用户组(重要)
# usermod -a -G git nginx
# chmod g+rx /home/git/
 
 3.生成ssl证书
# mkdir /usr/local/nginx/ssl
# cd /usr/local/nginx/ssl
# openssl req -new -x509 -nodes -days 3560 -out gitlab.crt -keyout gitlab.key
 
 4.开启Git over SSL
 # vi /home/git/gitlab/config/gitlab.yml
 
## GitLab settings
  gitlab:
    ## Web server settings
    host: git.example.com
    port: 443
    https: true
 
 # vi /home/git/gitlab-shell/config.yml
 
gitlab_url: "https://git.example.com"
http_settings:
#  user: someone
#  password: somepass
#  ca_file: /etc/ssl/cert.pem
#  ca_path: /etc/ssl/
  self_signed_cert: true

ca_file: "/usr/local/nginx/ssl/gitlab.crt"
 
5.启动nginx
# service nginx start

 
 6.打开web页面 git.example.com
git.example.com

注:视浏览器不同这里首先会提示证书不受信任,因为我们在此是自己给自己颁发的证书,所以非官方CA授权,有需要授权的朋友可以通过很多其他途径购买.

gitlab 社区版 安装 gitlab安装部署_nginx

GitLab默认的账号密码如下:

admin@local.host/5iveL!fe
 
 Client端配置:
 
六.上传git仓库
1.客户端生成秘钥
# cd ~
# ssh-keygen -t rsa
一路回车后生成公钥和秘钥对
$ cat ~/.ssh/id_rsa.pub

—————————————————————————————————————————————————

将这里生成的秘钥全部复制并粘贴到gitlab web SSH Keys后台保存即可

—————————————————————————————————————————————————

上传后如图:

gitlab 社区版 安装 gitlab安装部署_ico_02

2.测试SSH连接

# ssh -p22 git@git.example.com

若报如下错误:

——————————————————————————————————————
PTY allocation request failed on channel 1
/usr/bin/env: ruby: No such file or directory
Connection to git.example.com closed.
——————————————————————————————————————
说明服务端ruby环境变量未在此目录/usr/bin/ruby
在服务器端加此软链即可:
# ln -s /usr/local/ruby/bin/ruby /usr/bin/ruby
注:若服务器端SSH自定义端口,则需要在客户端~/.ssh/config下添加端口配置
假定自定义SSH端口为2222
# echo “Port 2222” >> ~/.ssh/config
 
 3.重新连接
# ssh -p22 git@git.example.com
——————————————————————————————————————
PTY allocation request failed on channel 1
Welcome to GitLab, Anonymous!
Connection to git.example.com closed.
——————————————————————————————————————

4.命令行上传git仓库
# su - 
# mkdir testprojiect
 # cd testprojiect/
# git init
# echo "What a fucking Hello World" > readme.txt
# git add .
# git commit -m 'first commit'
# git remote add origin git@git.example.com:root/testproject.git
# git push -u origin master

gitlab 社区版 安装 gitlab安装部署_git_03


大功告成...


注: 若主页CSS出现错误未加载, 可从新编译assets, 可从新获取CSS文件.

# cd /home/git/gitlab
# bundle exec rake assets:precompile RAILS_ENV=production

注: 解决Gravatar的头像加载timeout问题

搜索plain_url部分, 将原有部分改成:
plain_url: "http://gravatar.duoshuo.com/avatar/%{hash}?s=%{size}&d=identicon"#cd /home/git/gitlab
清除缓存
# RAILS_ENV=production bundle exec rake cache:clear
# service gitlab restart


注: 解决内存耗尽问题

如果你的VPS 为1G内存+1核处理器

建议将默认的unicorn worker_process设置为2, timeout设定为60s, 这样就不会因为长时间加载web页面而出现timeout等问题.

# vi /home/git/gitlab/config/unicorn.rb


... worker_processes 2 timeout 60 ...

官方推荐配置详见: https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/requirements.md

本文的Gitlab为6.3版本, 如果大家有升级到7.14或者8.0版本的需要的话, 可以参考官方的升级文档

https://github.com/gitlabhq/gitlabhq/blob/master/doc/update/6.x-or-7.x-to-7.14.md
