CentOS6.3下GitLab+Nginx(SSL)+MySQL+Ruby安装部署

showerlee 2014-08-29 22:12 Git 阅读 (24,039) 8条评论

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

         

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

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


server端配置:

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

  username: gitlab

  password: “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.orghttps://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

# exit

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

nginx直接跳转URL为https://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.

QQ20140829-7@2x

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:

QQ20140829-9@2x

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

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

Counting objects: 3, done.

Writing objects: 100% (3/3), 238 bytes | 0 bytes/s, done.

Total 3 (delta 0), reused 0 (delta 0)

To git@git.example.com:root/testproject.git

* [new branch]      master -> master

Branch master set up to track remote branch master from origin.

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

https://github.com/gitlabhq/gitlabhq/blob/master/doc/update/7.14-to-8.0.md

      @非常有帮助 建议放在同一台机器上, gitlab目前的后续版本你如果后期upgrade的话会抛弃nginx, 转而用gitlab自己开发的web engine.
      所以你这么隔离开以后更新会出现问题.

    群主,这篇文章里,在命令出全是#,我都不知道,你到底是切换git用户没了
    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

    • showerlee2016年12月7日下午12:43 回复

      “#”这个标示你如果经常用centOS可以注意到这个默认是root专属的shell command标示。
      所以我的所有命令都是在root下执行的,如果需要切换,我会使用su – “XXX”去更换用户。
