   When installing a fox head finally appears, the installation was successful.

3. Boot configuration
   directory structure
   / opt / gitlab home directory
   / etc / gitlab / profile directory
   / var / log / gitlab / log directory
   modify the configuration
   vim /etc/gitlab/gitlab.rb

   external_url 'http://10.10.10.55'    #这如果nginx 修改端口，external_url 里面也必须带端口
   gitlab_rails['time_zone'] = 'Asia/Shanghai'    #时区
   unicorn['worker_processes'] = 4    #依据服务器CPU核数
   nginx['listen_port'] = 80   #默认Nginx端口80，这里使用gitlab已有的Nginx服务，当然也可使用自己安装的Nginx服务。

   After modifying the configuration needs to be performed, reload the configuration:

   gitlab-ctl reconfigure

   gitlab start: gitlab-ctl Start
   gitlab view the status: gitlab-ctl status

4. Gitlab structure
   Gitlab and directories created according to the user defined configuration after startup, a default dependent component at / var / opt / gitlab directory.
   Gitlab main components are:

   Nginx: web access entry
   postgresql: database, or MySQL
   Redis: cache, distribute tasks
   sidekiq: background tasks, it is responsible for sending e-mail, tasks, from Redis
   Unicorn: gitlab main process
   gitlab-workhorse: a reverse proxy server that can handle the primary process unicorn unrelated request
   gitaly: back-office services, call processing git all Gitlab issued
   Speaking
   1. prepare the environment
   ready to install the finished package directory.
   cd / opt / src / Download

   git clone https://gitlab.com/xhang/gitlab.git

   2. Check the clone download the finished version of this patch

   # cat /opt/src/gitlab/VERSION 
   12.3.5

   3. Stop gitlab

   gitlab-ctl stop

   4. Check the installed version:

   head -1 /opt/gitlab/version-manifest.txt
   gitlab-ce 12.4.2

   5. Get finished package:

   cd /opt/src/gitlab
   git diff origin/12.3.5-stable origin/12.3.5-stable-zh > /tmp/12.3.5.diff

   6. Update patch to gitlab in:

   # yum -y install patch
   cd /tmp/
   #patch -d /opt/gitlab/embedded/service/gitlab-rails -p1 < 12.3.5.diff

   If you install the patch to perform the following problems, skip that carriage has been skipped. Because there are some newer patch package patch file, the files are not on gitlab.

   can't find file to patch at input line 5
   Perhaps you used the wrong -p or --strip option?
   The text leading up to this was:
   |diff --git a/app/assets/javascripts/awards_handler.js b/app/assets/javascripts/awards_handler.js
   |index 976d32a..7967edb 100644
   |--- a/app/assets/javascripts/awards_handler.js
   |+++ b/app/assets/javascripts/awards_handler.js

   7. reload the configuration and start Gitlab:

   gitlab-ctl reconfigure & gitlab-ctl start

   Log back Gitlab.
