第1章 系统准备

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 Repository baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/ gpgcheck=0 enabled=1
2.3安装gitlab-ce
yum makecache yum install gitlab-ce
2.4查看安装gitlab的版本
head -1 /opt/gitlab/version-manifest.txt gitlab-ce 9.1.2
2.5重新配置并启动Gitlab
# gitlab-ctl reconfigure会把一些过去的config还原,导致修改的端口以及域名等都没有了 gitlab-ctl reconfigure #重启gitlab-ce gitlab-ctl restart
第3章 安装MySQL5.6.36
3.1添加mysql源
vi /etc/yum.repo.d/mysql.repo [mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/7/$basearch/ enabled=1 gpgcheck=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> \q Bye #测试新用户是否能连接新的数据库 sudo -u git -H mysql -u git -p -Dgitlabhq_production Enter password: Reading table information for completion of tableand column names You 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'] = false gitlab_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gitlab gitlab-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/ Gemfile source '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gcc yum install gcc –y /opt/gitlab/embedded/bin/gem install mysql2 -v'0.3.20' Building native extensions. This could take a while... Successfully installed mysql2-0.3.20 Parsing documentation for mysql2-0.3.20 Installing ri documentation for mysql2-0.3.20 Done installing documentation for mysql2 after 1seconds 1 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 master Counting 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
