gitlab数据迁移至其他gitlb服务器上

需求：

A : 待迁移服务器，上边存有数据

B：接收项目得服务器，本身存在数据

验证方案：

一，搭建gitlab8.15.2

OS:rhel7.4

yum install policycoreutils-python.x86_64

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.15.2-ce.0.el7.x86_64.rpm

chmod 777 gitlab-ce-8.15.2-ce.0.el7.x86_64.rpm

rpm -ivh gitlab-ce-8.15.2-ce.0.el7.x86_64.rpm

########################更新配置文件########修改数据库为mysql###################

1）安装MySQL

wget -i -c  http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql-community-server

yum install mysql-devel

2）修改mysql密码

systemctl start mysqld.service

grep "password" /var/log/mysqld.log   ===》获得临时密码

mysql -uroot -p     # 回车后会提示输入密码

alter user 'root'@'localhost' identified by '123qweASD!';   ===》修改密码

set global validate_password_policy=0;  ===》关闭MySQL密码验证

set global validate_password_length=1;

3）创建必要数据库

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;

4）修改配置文件

vim /etc/gitlab/gitlab.rb

 

修改内容如下

external_url 'http://10.2.177.31:8090'  ===》AIP

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

 

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

修改内容如下：

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

 

5）重构

cd /opt/gitlab/embedded/bin/

./gem install mysql2 --version="0.3.20"

./gem install -i /opt/gitlab/embedded/service/gem/ruby/2.3.0/ mysql2 --version="0.3.20"

//gitlab-rake gitlab:setup

gitlab-ctl reconfigure

gitlab-ctl restart

6)检查

gitlab-rake gitlab:check
