Centos7下Gitlab迁移数据库mysql过程

第1章 系统准备

[root@test ~]# cat /etc/redhat-releaseCentOS Linux release 7.2.1511 (Core)[root@test ~]# uname -r3.10.0-327.el7.x86_64

1.1添加阿里云的镜像

cd /etc/yum.repos.d

#备份原镜像

mv CentOS-Base.repo CentOS-Base.repo.backup   #添加阿里云Base源wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo #添加阿里云epel源wget https://mirrors.aliyun.com/repo/epel-7.repo

#清除缓存yum clean all && yum makecache

第2章 yum安装最新版Gitlab9.1.2

2.1安装依赖软件

yum install curl policycoreutils openssh-serveropenssh-clients

2.2添加清华大学镜像

vi /etc/yum.repos.d/gitlab-ce.repo[gitlab-ce]name=Gitlab CE Repositorybaseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/gpgcheck=0enabled=1

2.3安装gitlab-ce

yum makecacheyum install gitlab-ce

2.4查看安装gitlab的版本

head -1 /opt/gitlab/version-manifest.txtgitlab-ce 9.1.2

2.5重新配置并启动Gitlab

# gitlab-ctl reconfigure会把一些过去的config还原，导致修改的端口以及域名等都没有了gitlab-ctl reconfigure #重启gitlab-cegitlab-ctl restart

第3章 安装mysql5.6.36

3.1添加mysql源

vi /etc/yum.repo.d/mysql.repo[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/7/$basearch/enabled=1gpgcheck=0

3.2mysql配置

yum -y install mysql-server mysql-devel #基本配置，新建密码等mysql_secure_installation   #登录数据库mysql -uroot -p$password   #查看用户情况mysql> select user,host from mysql.user;+------+-----------+| user | host     |+------+-----------+| root | 127.0.0.1 || root | ::1      || root | localhost || root | test     |+------+-----------+4 rows in set (0.03 sec) #创建一个gitlab管理用户mysql> CREATE USER 'git'@'localhost' IDENTIFIED BY '123456';Query OK, 0 rows affected (0.00 sec) #创建gitlab数据库mysql> CREATE DATABASE IF NOT EXISTS`gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_general_ci`;Query OK, 1 row affected (0.00 sec) #授予git用户对gitlabhq_production数据库所有表的权限mysql> GRANT SELECT, INSERT, UPDATE, DELETE,CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES, REFERENCES ON`gitlabhq_production`.* TO 'git'@'localhost';Query OK, 0 rows affected (0.00 sec) #使修改用户生效mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> \qBye #测试新用户是否能连接新的数据库sudo -u git -H mysql -u git -p -Dgitlabhq_productionEnter password:Reading table information for completion of tableand column namesYou can turn off this feature to get a quickerstartup with -A Welcome to the MySQL monitor.

第4章 配置Gitlab连接mysql

4.1修改/etc/gitlab/gitlab.rb

postgresql['enable'] = falsegitlab_rails['db_adapter'] = 'mysql2'gitlab_rails['db_encoding'] = 'utf8'gitlab_rails['db_host'] = '127.0.0.1'gitlab_rails['db_port'] = '3306'gitlab_rails['db_username'] = 'git'gitlab_rails['db_password'] = '123456'按官方文档重新配置gitlabgitlab-ctl reconfigure迁移数据库时出现以下错误

第5章 排错步骤

5.1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 --addhttps://gems.ruby-china.org/ --remove https://rubygems.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/ Gemfilesource 'https://gems.ruby-china.org'

5.2bundle install安装更新

#此命令会尝试更新系统中已存在的gem包
/opt/gitlab/embedded/bin/bundle install

#执行该命令需要切换到Gemfile上一级目录才可以运行
cd /opt/gitlab/embedded/service/gitlab-rails/
/opt/gitlab/embedded/bin/bundle install

5.3bundle禁止使用postgresql

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

5.4 安装mysql2 "0.3.20"

gitlab-rake gitlab:check

#安装mysql2 0.3.20版本/opt/gitlab/embedded/bin/gem install mysql2 -v'0.3.20'出错

查看文件后发现没有安装gcc软件，导致不能编译文件。故需要yum安装gccyum install gcc -y /opt/gitlab/embedded/bin/gem install mysql2 -v'0.3.20'Building native extensions.  This could take a while...Successfully installed mysql2-0.3.20Parsing documentation for mysql2-0.3.20Installing ri documentation for mysql2-0.3.20Done installing documentation for mysql2 after 1seconds1 gem installed

5.5重置检查

#重新配置gitlab-ctl reconfigure#检查gitlab-rake gitlab:check

5.6客户端测试

[root@test chen]# touch README.md[root@test chen]# git add README.md[root@test chen]# git commit -m "addREADME"[master（根提交） bed61ad] addREADME 1 filechanged, 0 insertions(+), 0 deletions(-) create mode100644 README.md[root@test chen]# git push -u origin masterCounting objects: 3, done.Writing objects: 100% (3/3), 216 bytes | 0 bytes/s,done.Total 3 (delta 0), reused 0 (delta 0)To git@10.0.0.10:root/chen.git * [newbranch]      master -> master分支 master 设置为跟踪来自 origin 的远程分支 master。

成功
