gitlab 源码安装=》rpm安装横向迁移（version 9.0）

准备：

下载版本地址：

https://packages.gitlab.com/gitlab/gitlab-ce

迁移环境：

源码安装的gitlab9.0.13

目标迁移至9.0.13 RPM安装的环境

###################源码安装gitlab9.0.13############参考官方文档

https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/

###################RPM安装gitlab9.0.13#######################

https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

OS :rhel7.4

关闭防火墙： setenforce 0

修改主机名： vim /etc/hostname  /etc/sysconfig/network   /etc/hosts

安装依赖包：

yum install curlopenssh-server openssh-clients postfix -y

安装glibc新版：

 rpm -ivh gitlab-ce-9.x.x-ce.0.el7.x86_64.rpm

 编辑文件

vim /etc/gitlab/gitlab.rb

修改如下：

external_url 'http://10.2.177.57:8090'

重置配置

gitlab-ctl reconfigure

gitlab-ctl restart

 #################################备份还原#####################

一，备份

cd /home/git/gitlab

sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production

cd tmp/backups/

 scp XXXX  root@IP:/var/opt/gitlab/backups/

二，RPM服务器停止服务

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

cd /var/opt/gitlab/backups/

gitlab-rake gitlab:backup:restore BACKUP=1542476495_2018_11_18

=======》报错    =====》解决： ln -s /usr/local/mysql/bin/mysql  /usr/bin/mysql

Errno::ENOENT: No such file or directory - mysql

(See full trace by running task with --trace)

仓库要单独打包还原到/var/opt/gitlab/git-data/repositories

三，启动服务

gitlab-ctl start 

四，额外配置

假设源码使用的MySQL数据库

修改RPM默认的数据库

1）登陆MySQL&配置

CREATE USER 'git'@'localhost' IDENTIFIED BY '123456';

SET GLOBAL innodb_file_per_table=1, innodb_file_format=Barracuda, innodb_large_prefix=1;

CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_general_ci`;

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES, REFERENCES ON `gitlabhq_production`.* TO 'git'@'localhost';

flush privileges;

2)修改gitlab配置文件

vim /etc/gitlab/gitlab.rb

gitlab_rails['db_adapter'] = "mysql2"
gitlab_rails['db_encoding'] = "utf8"
gitlab_rails['db_database'] = "gitlabhq_production"
gitlab_rails['db_username'] = "git"
gitlab_rails['db_password'] = "123456"
gitlab_rails['db_host'] = "127.0.0.1"
gitlab_rails['db_port'] = 3306
postgresql['enable'] = false

3)消除postgresql依赖

vim /opt/gitlab/embedded/service/gitlab-rails/.bundle/config

修改内容为：

BUNDLE_WITHOUT: "development:test:postgres"  ===》MySQL改为postgres

保存

重新启动配置

gitlab-ctl reconfigure

4)安装MySQL依赖

cd /opt/gitlab/embedded/bin/

./gem install mysql2  -v “0.3.20” ===>默认安装的是0.3.20

gitlab-rake gitlab:check  ====》运行该命令会提示版本是否正确  ===》其余信息不用看

  ==>这里可能i显示没有mysql2 0.3.20版本，修改Gemfile文件，修改完成cd /opt/gitlab/embedded/service/gitlab-rails/  && /opt/gitlab/embedded/bin/bundle install

gitlab-rake gitlab:setup  gitlab初始化

初始化完成之后可以执行 gitlab-rake gitlab:check检查

5）启动服务

gitlab-ctl restart

gitlab-ctl status 查看启动信息
