gitlab 数据迁移、升级打怪之路：8.8.5--> 8.10.8 --> 8.17.8 --> 9.5.9 --> 10.1.4 --> 10.2.5
打怪之路背景介绍：
    我们的gitlab服务器原先服务器版本是8.8.5,使用的是源码安装，每个插件单独安装，数据库使用的是mysql5.6.39，
    现在有个需求是升级gitlab的版本。现在最新的gitlab的版本是11.0.2
    https://about.gitlab.com/blog/categories/releases/
    gitlab的版本更新也真是快，所以这里我们决定升级。
    因为我们使用的是源码安装，升级不太方便，同时gitlab不支持跨版本的数据迁移。所以......看下面：
1、新买一台服务器使用rpm（或者yum）的方式安装gitlab-ce-8.8.5（我这里用的是rpm包）
2、在老的gitlab服务器上备份数据，然后导入到新服务器的gitlab上。
3、数据导入完毕后，开始一步一步的版本升级。本次版本升级的历程是这样的：
    8.8.5--> 8.10.8 --> 8.17.8 --> 9.5.9 --> 10.1.4 --> 10.2.5

gitlab 安装包下载路径：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

gitlab 上部署pages：https://www.chenxuefei.com/2017/build-gitlab-pages/

1、初始化服务器
cd /init
sudo sh init.sh live test-gitlab

2、下载gitlab对应版本的安装包。这里我们下载8.8.5
cd /data/tools
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.8.5-ce.1.el7.x86_64.rpm

3、这里我们因为要设置把默认的数据库postgrasql 修改为mysql
这里我们之前的mysql 是5.6
所以这里我们使用yum 的形式来安装mysql
centos自带的repo是不会自动更新每个软件的最新版本，所以无法通过yum方式安装MySQL的高级版本。
所以，即使使劲用yum -y install mysql mysql-server mysql-devel，也是没用的。
所以，正确的安装mysql5姿势是要先安装带有可用的mysql5系列社区版资源的rpm包
cd /data/tools
sudo rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

这个时候查看当前可用的mysql安装资源：
[wwwad@test-gitlab tools]$ yum repolist enabled | grep "mysql.*-community*"
mysql-connectors-community/x86_64 MySQL Connectors Community                  51
mysql-tools-community/x86_64      MySQL Tools Community                       63
mysql56-community/x86_64          MySQL 5.6 Community Server                 395

这里我们只安装mysql-server 和 mysql-client
sudo yum -y install mysql-community-server
这里我们可以看到进度条中我们安装的是mysql5.6.40
开机自启动
sudo systemctl enable mysqld
启动
sudo systemctl start mysqld
重置密码
mysql_secure_installation

下面就是mysql有关gitlab的一些操作了
mysql> CREATE DATABASE IF NOT EXISTS`gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_general_ci`;
Query OK, 1 row affected (0.00 sec)

> GRANT SELECT, INSERT, UPDATE, DELETE,CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES, REFERENCES ON`gitlabhq_production`.* TO 'git'@'localhost' identified by "123456";
Query OK, 0 rows affected (0.00 sec)

> flush privileges;

4、接下来就是安装gitlab了
cd /data/tools/
sudo rpm -ivh gitlab-ce-8.8.5-ce.1.el7.x86_64.rpm

gitlab 的配置文件是/etc/gitlab/gitlab.rb
sudo vim /etc/gitlab/gitlab.rb
修改gitlab的访问地址
external_url "http://git.bigbao.com"

这里gitlab的默认配置文件使用的数据库是postgresql,这里我们要给他改成mysql的
postgresql['enable'] = false
gitlab_rails['db_adapter'] = 'mysql2'
gitlab_rails['db_encoding'] = 'utf8'
gitlab_rails['db_host'] = '10.19.104.17'
gitlab_rails['db_port'] = '3306'
gitlab_rails['db_username'] = 'git'
gitlab_rails['db_password'] = '123456'

执行：
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

bundle禁止使用postgresql：不要舍弃mysql包
sudo vi /opt/gitlab/embedded/service/gitlab-rails/.bundle/config
把mysql替换成postgresql

安装插件ruby插件，要不然执行gitlab:check 会报错，如果没有安装mysql-devel库也会有提示的。
cd /opt/gitlab/embedded/bin/
这里我们更换gem 源

#查看gem源
/opt/gitlab/embedded/bin/gem source
*** CURRENT SOURCES ***

https://rubygems.org/

#更换开源中国的gem源,否则使用时会出现错误
/opt/gitlab/embedded/bin/gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/

/opt/gitlab/embedded/bin/gem sources --add https://rubygems.org/ --remove https://gems.ruby-china.org/

#查看更好后的gem源
/opt/gitlab/embedded/bin/gem sources
*** CURRENT SOURCES ***

https://gems.ruby-china.org/

#更改配置Gemfile文件的gem源
vi /opt/gitlab/embedded/service/gitlab-rails/Gemfile
source 'https://gems.ruby-china.org'

bundle install安装更新
cd /opt/gitlab/embedded/service/gitlab-rails/
执行下面的命令之前必须执行上面这一步，在这个目录下执行才有效
sudo /opt/gitlab/embedded/bin/bundle install ---》这个命令会尝试更新系统中已经存在的gem包
报错了：
An error occurred while installing mysql2 (0.3.20), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.20'` succeeds before bundling.

执行一下

这里报错了：
libmysqlclient is missing. You may need to 'apt-get install libmysqlclient-dev' or 'yum install mysql-devel', and try again.

yum install mysql-devel
cd /opt/gitlab/embedded/service/gitlab-rails/
sudo /opt/gitlab/embedded/bin/gem install mysql2 -v'0.3.20' 这里安装之后check 的话一直说没有，就用了下面指定-i的方法。gem源我也是一直在切换china 和官方源来回切
Building native extensions. This could take a while...
Successfully installed mysql2-0.3.20
Parsing documentation for mysql2-0.3.20
Installing ri documentation for mysql2-0.3.20
Done installing documentation for mysql2 after 0 seconds
1 gem installed

这里我们要指定 -i 路径。之前这里被坑了
cd /opt/gitlab/embedded/service/gitlab-rails/
sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.1.0 mysql2 -v'0.3.20'
[root@test-gitlab backups]# sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.1.0 mysql2 -v'0.3.20'
Building native extensions. This could take a while...
Successfully installed mysql2-0.3.20 这里会提示success
1 gem installed

这里我check的时候提示没有表，先不管，我们那老机器的备份文件来恢复
gitlab-rake gitlab:backup:restore BACKUP:1530554436

还是提示没有相关表
那么执行初始化数据库
gitlab-rake gitlab:setup

gitlab-rake gitlab:backup:restore BACKUP:1530554436
再次报错
ActiveRecord::StatementInvalid: Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'keys CASCADE' at line 1: DROP TABLE IF EXISTS keys CASCADE

》》keys占用了关键字，导入备份drop表的时候报错了，登录到数据库drop tables `keys`;成功删除表后，重新导入备份

mysql> use gitlabhq_production;
mysql> drop tables `keys`;

再来：
gitlab-rake gitlab:backup:restore BACKUP:1530554436

终于导入成功了。要死人啊

这里我配置的URL是git.bigbao.com

所以这里修改数据库
use gitlabhq_production;

update application_settings set signin_enabled = '1';

update application_settings set home_page_url = 'http://git.bigbao.com';

update application_settings set after_sign_out_path = 'http://git.bigbao.com'

浏览器访问登录 http://git.bigbao.com
访问成功，yes,感谢上帝，点击项目，我擦，500 了
看日志
tail -f production.log

接下来不如gitlab的正式升级之路
升级目前的流程定位8.8.5--> 8.10.8 --> 8.17.8 --> 9.5.9 --> 10.1.4
我们现在下载8.10.8 安装包
cd /data/tools
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.10.8-ce.0.el7.x86_64.rpm

关闭gitlab 的部分服务：
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-8.10.8-ce.0.el7.x86_64.rpm
[wwwad@test-gitlab tools]$ sudo rpm -Uvh gitlab-ce-8.10.8-ce.0.el7.x86_64.rpm

gitlab preinstall: try again:

又报错，解决，mysql去给这个host授权一下。目前只受理了select，我擦，select的权限还是权限拒绝，添加权限
mysql> GRANT SELECT, INSERT, UPDATE, DELETE,CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES, REFERENCES ON`gitlabhq_production`.* TO 'git'@'git.bigbao.com' identified by '123456';

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

再次执行：sudo rpm -Uvh gitlab-ce-8.10.8-ce.0.el7.x86_64.rpm
又报别的错误了：
    Error executing action `run` on resource 'bash[migrate gitlab-rails database]'

    STDOUT: rake aborted!
    Gem::LoadError: Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

这个mysql2 我已经添加到gem里面了，我去

BUNDLE_RETRY: 5
BUNDLE_PATH: "/opt/gitlab/embedded/service/gem"
BUNDLE_JOBS: 9
BUNDLE_WITHOUT: development:test:mysql
BUNDLE_DISABLE_SHARED_GEMS: '1'

我们看到这里变成了mysql
我们修改一下，把这里的mysql变成postgresql

重新配置gitlab和重启
gitlab-ctl reconfigure
gitlab-ctl restart

yes 升级成功，我的小心脏。。。

我们登录到git.bigbao.com 查看一下面板，终于变成了8.10.8

接下来我们升级到8.17.8
cd /data/tools
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.17.8-ce.0.el7.x86_64.rpm
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-8.17.8-ce.0.el7.x86_64.rpm
果然又报上面的同一个错误了，这个错误是在检测的时候报的错误。我们不需要再次执行rpm -Uvh gitlab-ce-8.17.8-ce.0.el7.x86_64.rpm，
执行一下也没有问题。会提示你已经安装    package gitlab-ce-8.17.8-ce.0.el7.x86_64 is already installed
sudo sed -i "s#mysql#postgresql#g" /opt/gitlab/embedded/service/gitlab-rails/.bundle/config
我擦，这样修改尽然不可以了
仔细看一下报错内容：尽然和上面的报错不一样，大意了
================================================================================
    Error executing action `run` on resource 'bash[migrate gitlab-rails database]'
    ================================================================================

    Mixlib::ShellOut::ShellCommandFailed

    You'll need to update your bundle to a different version of rake (10.5.0) that hasn't been removed in order to install.

这里我们查看gem源是官方国外源，修改一下
cd /opt/gitlab/embedded/service/gitlab-rails/
/opt/gitlab/embedded/bin/gem source

又报错：

Make sure that `gem install charlock_holmes -v '0.7.3'` succeeds before bundling.

sudo /opt/gitlab/embedded/bin/gem install bundler

再次报错：

报错再解决：
yum -y install gcc automake autoconf libtool make gcc-c++

再执行：sudo /opt/gitlab/embedded/bin/gem install charlock_holmes -v '0.7.3'
好了，通过

gitlab-ctl reconfigure

处理思路：
sudo /opt/gitlab/embedded/bin/bundle install
一个报错没解决，又来一个：
Downloading omniauth-google-oauth2-0.4.1 revealed dependencies not in the API or the lockfile (omniauth-oauth2 (>= 1.3.1), jwt (~> 1.5.2)).
Either installing with `--full-index` or running `bundle update omniauth-google-oauth2` should fix the problem.

In Gemfile:
omniauth-google-oauth2

sudo /opt/gitlab/embedded/bin/bundle install --full-index
报相同的错误，那么执行
sudo /opt/gitlab/embedded/bin/bundle update omniauth-google-oauth2
又来一个报错：屋漏偏逢连夜雨......

pg

解决方案：
sudo yum install freetype-devel ghostscript-devel jasper-devel lcms-devel libpng-devel libtiff-devel zlib-devel libxml2-devel
sudo yum install ImageMagick-devel
sudo yum install postgresql-devel
sudo /opt/gitlab/embedded/bin/gem install pg -v '0.18.4'

再次执行：
sudo /opt/gitlab/embedded/bin/bundle update omniauth-google-oauth2

又报错：

      修改过之后还是有之前一样的报错，DBA帮忙看了一下还是要修改，使用下面的sql，dba说可能只要执行下面这个，上面的不用执行，但是这个之前已经执行过了，等到线上版本真正升级的时候，再试试只用下面的sql
      这里在第二次进行升级的时候验证了。只要执行下面这一句sql 就行
      use gitlabhq_production;
      ALTER TABLE `members` MODIFY COLUMN `source_type` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL AFTER `source_id`;
访问成功，yes

gitlab 访问502 Google 说可能是unicorn的问题，查看日志，是mysql授权问题

接下来接着干,升级到9.5.9
cd /data/tools/
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-9.5.9-ce.0.el7.x86_64.rpm
这里把后面要升级用到的压缩包都下载下来：
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.8.5-ce.0.el7.x86_64.rpm

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-9.5.9-ce.0.el7.x86_64.rpm
下面截取了一段升级的进度条，可以看到它做了哪些事情

我们之前装的是0.3.20,按照报错提示他是找不到mysql2-0.4.5，找不到，那我们就装
cd /opt/gitlab/embedded/service/gitlab-rails/
sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.3.0 mysql2 -v'0.4.5'

我们之前把包都是安装在/opt/gitlab/embedded/service/gem/ruby/2.1.0 ，现在都是安装在2.3.0下面
[root@test-gitlab gitlab-rails]# ls /opt/gitlab/embedded/service/gem/ruby/2.3.0/gems/mysql2-0.
mysql2-0.3.20/ mysql2-0.4.5/
我们可以看到已经有mysql2-0.4.5
这里我刚刚尝试了一下不指定 -i 的话，他这里也没有报错，但是到路径下面找，找不到

gitlab-clt reconfigure
又来一个报错

cd /opt/gitlab/embedded/service/gitlab-rails/
sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.3.0/ peek-mysql2 -v'1.1.0'

这里出现一个诡异的现象就是我执行上面那一步的时候。提示安装成功了，/opt/gitlab/embedded/service/gem/ruby/2.3.0/gems 目录下也有了
但是 gitlab-ctl reconfigure的时候还是报错，于是抱着试试的态度，执行了下面的语句
sudo /opt/gitlab/embedded/bin/gem install peek-mysql2 -v'1.1.0'
但是我看历史命令我好像没有执行sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.3.0/ peek-mysql2 -v'1.1.0'
可能是我真的没有执行吧，错误排除就好

第二次遇到的错误：
Bundler::PermissionError: There was an error while trying to write to `/opt/gitlab/embedded/service/gitlab-rails/Gemfile.lock`. It is likely that you need to grant write permissions for that path.
说没有权限写入。那么chmod 777 /opt/gitlab/embedded/service/gitlab-rails/Gemfile.lock
问题解决

再次执行gitlab-ctl reconfigure
gitlab-ctl restart
访问又报错：500

接下来接着干，搞10.1.4
cd /data/tools
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm
没想到在这一步就报错了。你尽然需要policycoreutils-python，那我就给你装
[root@test-gitlab tools]# sudo sudo rpm -Uvh gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm
warning: gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY
error: Failed dependencies:
policycoreutils-python is needed by gitlab-ce-10.1.4-ce.0.el7.x86_64

sudo yum -y install policycoreutils-python

sudo vi /opt/gitlab/embedded/service/gitlab-rails/.bundle/config
把mysql替换成postgresql
gitlab-ctl reconfigure
gitlab-ctl restart

第一次我们从10.1.4--->10.8.5升级失败了，现在跨度小一点
现在升级到10.2.5
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-10.2.5-ce.0.el7.x86_64.rpm
sudo vi /opt/gitlab/embedded/service/gitlab-rails/.bundle/config
把mysql替换成postgresql
gitlab-ctl reconfigure
gitlab-ctl restart
升级成功，

现在升级到10.3.9有数据库结构问题
按照https://gitlab.com/gitlab-org/gitlab-ce/issues/41483方法修改无效，决定到此为止，不在往上升级

下面的忽略这个是之前10.1.4直接往10.8.5升级的。错误也保留在这里，方便以后有空查看
接下来接着干，搞10.8.5
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx
sudo rpm -Uvh gitlab-ce-10.8.5-ce.0.el7.x86_64.rpm

上面我们装的是mysql2 0.4.5的版本，按照报错需要装0.4.10，你要啥我就给你啥
cd /opt/gitlab/embedded/service/gitlab-rails/
sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/embedded/service/gem/ruby/2.3.0 mysql2 -v'0.4.10'

干，又报错：
        [wwwad@test-gitlab gitlab-rails]$ sudo /opt/gitlab/embedded/bin/gem install mysql2 -v'0.4.10'
        Fetching: mysql2-0.4.10.gem (100%)

Google让我执行bundle install
sudo vim /opt/gitlab/embedded/service/gitlab-rails/Gemfile
改成https://gems.ruby-china.org

sudo /opt/gitlab/embedded/bin/bundle install
报错信息：

An error occurred while installing mysql2 (0.4.10), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.4.10' --source 'https://gems.ruby-china.org/'` succeeds before bundling.

In Gemfile:
peek-mysql2 was resolved to 1.1.0, which depends on
mysql2

sudo /opt/gitlab/embedded/bin/gem install -i /opt/gitlab/<em></em>bedded/service/gem/ruby/2.3.0 mysql2 -v'0.4.10'

https://ruby-china.org/topics/18737?locale=en ruby升级到2.3.7 最后问了一下群里的朋友。说是我没有安装ruby-devel。
