１　关于gitlab7

无论如何gitlab是个好东西，但是极难安装和配置。bitnami(https://bitnami.com/)的一键安装包虽然可以解决大问题，但是仍有很多人无法配置gitlab+nginx和email发送等等问题。今天特意完整地再梳理一次。对各位读者的问题不再逐一解答。

首先，bitmami的一些版本有问题，无法成功在rhel6.4上成功安装。因此，我找到了一个较新的可以使用的版本7.8.1（响应式页面）：

ftp://pepstack.com/pub/tarball/bitnami-gitlab-7.8.1-0-linux-x64-installer.run

（我的ftp不会一直提供，请想要的尽快下载）

那么，最后安装好的效果就是（点击可访问，第一次访问可能会比较慢，要求较新版本的firefox或chrome，IE未测试）：

http://pepstack.com/gitlab

２　需求描述

好了，先把需求陈述一下，如果读者的需求与我不同，我无能为力。假设我有一台web主机（我这里是pepstack.com)，我在主机后面创建虚拟机（vm-gitlab），在vm-gitlab上安装gitlab7，然后通过配置web主机上的ngnix，可以通过下面的url访问到我的gitlab:

http://pepstack.com/gitlab

创建虚拟机vm-gitlab的过程不细说了，如果你使用实体机也是一样的。vm-gitlab安装的是rhel6.4版本。确保在vm内部可以访问外部主机和internet(如ping www.baidu.com)。

３　安装gitlab

ssh 到vm-gitlab：

# ssh root@vm-gitlab

下载一键式安装包：

# wget ftp://pepstack.com/pub/tarball/bitnami-gitlab-7.8.1-0-linux-x64-installer.run

安装：

# chmod a+x bitnami-gitlab-7.8.1-0-linux-x64-installer.run
# ./bitnami-gitlab-7.8.1-0-linux-x64-installer.run
安装过程中会提示：

４　配置gitlab

配置尤其要小心。下面几个配置文件要用到：

/opt/gitlab-7.8.1-0/apps/gitlab/htdocs/config/environments/production.rb
/opt/gitlab-7.8.1-0/apps/gitlab/htdocs/config/initializers/smtp_settings.rb
/opt/gitlab-7.8.1-0/apps/gitlab/htdocs/config/gitlab.yml
/opt/gitlab-7.8.1-0/apps/gitlab/conf/httpd-app.conf
/opt/gitlab-7.8.1-0/apps/gitlab/gitlab-shell/config.yml

下面逐一说明：

4.1 production.rb

......
  # config.action_mailer.delivery_method = :sendmail
  # Defaults to:
  # # config.action_mailer.sendmail_settings = {
  # #   location: '/usr/sbin/sendmail',
  # #   arguments: '-i -t'
  # # }
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address => "smtp.qq.com",
    :port => "25",
    :domain => "qq.com",
    :authentication => :plain,
    :user_name => "cheungmine@qq.com",
    :password => "********",
    :enable_starttls_auto => true
  }

  config.eager_load = true
  config.assets.js_compressor = :uglifier

  config.allow_concurrency = false
......

4.2 smtp_settings.rb

# cp smtp_settings.rb.sample smtp_settings.rb

# To enable smtp email delivery for your GitLab instance do the following:
# 1. Rename smtp_settings.rb.sample to smtp_settings.rb
# 2. Edit settings inside this file
# 3. Restart GitLab instance
#
if Rails.env.production?
  Gitlab::Application.config.action_mailer.delivery_method = :smtp

  ActionMailer::Base.smtp_settings = {
    address: "smtp.qq.com",
    port: 25,
    user_name: "cheungmine@qq.com",
    password: "********",
    domain: "qq.com",
    authentication: :login,
    enable_starttls_auto: true,
    openssl_verify_mode: 'none'
  }
end

4.3 gitlab.yml

# # # # # # # # # # # # # # # # # #
# GitLab application config file  #
# # # # # # # # # # # # # # # # # #
#
# How to use:
# 1. Copy file as gitlab.yml
# 2. Update gitlab -> host with your fully qualified domain name
# 3. Update gitlab -> email_from
# 4. If you installed Git from source, change git -> bin_path to /usr/local/bin/git
# 5. Review this configuration file for other settings you may want to adjust

production: &base
  #
  # 1. GitLab app settings
  # ==========================

  ## GitLab settings
  gitlab:
    ## Web server settings (note: host is the FQDN, do not include http://)
    host: pepstack.com
    port: 80                # Set to 443 if using HTTPS, see installation.md#using-https for additional HTTPS configuration details
    https: false            # Set to true if using HTTPS, see installation.md#using-https for additional HTTPS configuration details

    # Uncommment this line below if your ssh host is different from HTTP/HTTPS one
    # (you'd obviously need to replace ssh.host_example.com with your own host).
    # Otherwise, ssh host will be set to the `host:` value above
    # ssh_host: ssh.host_example.com

    # WARNING: See config/application.rb under "Relative url support" for the list of
    # other files that need to be changed for relative url support
    relative_url_root: /gitlab

    # Uncomment and customize if you can't use the default user to run GitLab (default: 'git')
    # user: git

    ## Date & Time settings
    # Uncomment and customize if you want to change the default time zone of GitLab application.
    # To see all available zones, run `bundle exec rake time:zones:all RAILS_ENV=production`
    # time_zone: 'UTC'

    ## Email settings
    # Uncomment and set to false if you need to disable email sending from GitLab (default: true)
    # email_enabled: true
    # Email address used in the "From" field in mails sent by GitLab
    email_from: cheungmine@qq.com
    support_email: cheungmine@qq.com

    # Email server smtp settings are in config/initializers/smtp_settings.rb.sample

    # default_can_create_group: false  # default: true
    # username_changing_enabled: false # default: true - User can change her username/namespace
    ## Default theme
    ##   BASIC  = 1
    ##   MARS   = 2
    ##   MODERN = 3
    ##   GRAY   = 4
    ##   COLOR  = 5
    # default_theme: 2 # default: 2
......

上面文件改动之处在于:

host: pepstack.com
relative_url_root: /gitlab
email_from: cheungmine@qq.com
support_email: cheungmine@qq.com

下面的配置是因为要把gitlab置于nginx后面使用：

4.4 httpd-app.conf

<Directory "/opt/gitlab-7.8.1-0/apps/gitlab/htdocs/public">
    Options -MultiViews
    AllowOverride All
    <IfVersion < 2.3 >
        Order allow,deny
        Allow from all
    </IfVersion>
    <IfVersion >= 2.3>
        Require all granted
    </IfVersion>

    SetEnv RAILS_RELATIVE_URL_ROOT "/gitlab"

    PassengerEnabled on
    PassengerAppRoot "/opt/gitlab-7.8.1-0/apps/gitlab/htdocs/"
    <IfModule pagespeed_module>
        ModPagespeedDisallow "*"
    </IfModule>
    PassengerUser git
    PassengerGroup git
    SetEnv MAGIC "/opt/gitlab-7.8.1-0/ruby/lib/ruby/gems/2.0.0/gems/charlock_holmes-0.6.9.4/ext/charlock_holmes/src/file-5.08/magic/magic.mgc"
    SetEnv PATH "/opt/gitlab-7.8.1-0/python/bin:${PATH}"

</Directory>
PassengerPreStart http://127.0.0.1:80/gitlab

不同之处在于：

SetEnv RAILS_RELATIVE_URL_ROOT "/gitlab"
PassengerPreStart http://127.0.0.1:80/gitlab

4.5 config.yml

...
gitlab_url: http://pepstack.com:80/gitlab/
...

这样我们访问gitlab就是按照下面的地址：

http://pepstack.com/gitlab/

5 主机nginx配置

上面的配置都是在vm-gitlab上进行的，注意打开80:http端口。下面要给主机nginx增加配置，配置文件：

/etc/nginx/conf.d/redmine.conf

内容如下（我同时还提供了redmine服务）：

# 指向内网redmine的web服务(192.168.122.21:80)
#
upstream redmine {
    server 192.168.122.21:80;
}

upstream gitlab {
    server 192.168.122.20:80;
}

server {
    server_name pepstack.com;

    # /var/log/nginx 本地目录必须存在
    access_log  /var/log/nginx/redmine_access.log;
    error_log   /var/log/nginx/redmine_error.log;

    location /redmine {
        try_files $uri @red;      # @red 名字是任意的
    }

    location /gitlab {
        try_files $uri @git;
    }

    location @red {
        proxy_set_header  Host             $host;
        proxy_set_header  X-Real_IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_read_timeout     300;
        proxy_connect_timeout  300;
        proxy_redirect         off;

        proxy_pass http://redmine;  # 指向 upstream redmine
    }

    location @git {
        proxy_set_header  Host             $host;
        proxy_set_header  X-Real_IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_read_timeout     300;
        proxy_connect_timeout  300;
        proxy_redirect         off;

        proxy_pass http://gitlab;  # 指向 upstream gitlab
    }
}

注意修改：

/etc/nginx/nginx.conf

......
http {
......
        include /etc/nginx/conf.d/*.conf;
        #  include /etc/nginx/sites-enabled/*;
}
......

即注释掉：include /etc/nginx/sites-enabled/*;

６　启动服务

大功告成，在主机启动nginx:

$ sudo nginx -s reload

在vm-gitlab启动gitlab:

# cd /opt/gitlab-7.8.1-0/

# ./ctlscript.sh restart
