GitLab是用于仓库管理系统的开源项目，一般安装于Ubuntu和Debian系统，当然也可以安装于CentOS系统，今天给大家介绍的就是GitLab在CentOS系统下的安装，以及GitLab安装前的配置。
前置要求
一定要先关闭iptable与selinux
本文安装的系统为centos 6.2 64位系统，安装在dell r410机器
1、安装epel与基础依赖库及软件
cd /tmp
wget http://download.Fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
1rpm -Uvh epel-release-6-8.noarch.rpm
2yum install -y readline-devel libyaml-devel gdbm-devel ncurses-devel redis openssl-devel
3zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel
4tk-devel libxml2-devel libffi-devel libxslt-devel libicu-devel httpd httpd-devel gitolite git-all python-devel python-pip sqlite-devel sendmail vim mysql-devel mysql-server patch libyaml* pcre-devel
2、安装ruby（一般默认安装都是1.8的，官方要求1.9以上）
mkdir /tmp/ruby && cd /tmp/ruby
curl --progress http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p392.tar.gz | tar xz
cd ruby-1.9.3-p392/
。/configure
make
make install
gem install bundler
ln -s /usr/local/bin/ruby /usr/bin/ruby
ln -s /usr/local/bin/gem /usr/bin/gem
ln -s /usr/local/bin/bundle /usr/bin/bundle
3、创建一个git用户供GitLab使用
adduser --comment ‘GitLab’ git
chmod –R 755 /home/git
4、安装gitlab 的shell
# Login as git
sudo su git
# Go to home directory
cd /home/git
# Clone gitlab shell
git clone https://github.com/gitlabhq/gitlab-shell.git
cd gitlab-shell
# switch to right version
git checkout v1.3.0
cp config.yml.example config.yml
# Edit config and replace gitlab_url
# with something like ‘http://domain.com/’
vim config.yml
# Do setup
。/bin/install
5、建立gitlab数据库并授权
# Login to MySQL
mysql -u root -p
# Create a user for GitLab. （change $password to a real password）
mysql》 CREATE USER ‘gitlab’@‘localhost’ IDENTIFIED BY ‘gitlab’;
# Create the GitLab production database
mysql》 CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
# Grant the GitLab user necessary permissopns on the table.
mysql》 GRANT SELECT， LOCK TABLES， INSERT， UPDATE， DELETE， CREATE， DROP， INDEX， ALTER ON `gitlabhq_production`.* TO ‘gitlab’@‘localhost’;
# Quit the database session
mysql》 q
6、克隆gitlab源
# Clone GitLab repository
cd /home/git
sudo -u git -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab
# Go to gitlab dir
cd /home/git/gitlab
# Checkout to stable release
sudo -u git -H git checkout 5-1-stable
Configure it
cd /home/git/gitlab
# Copy the example GitLab config
sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml
# Make sure to change “localhost” to the fully-qualified domain name of your
# host serving GitLab where necessary
sudo -u git -H vim config/gitlab.yml
# Make sure GitLab can write to the log/ and tmp/ directories
sudo chown -R git log/
sudo chown -R git tmp/
sudo chmod -R u+rwX log/
sudo chmod -R u+rwX tmp/
# Create directory for satellites
sudo -u git -H mkdir /home/git/gitlab-satellites
# Create directories for sockets/pids and make sure GitLab can write to them
sudo -u git -H mkdir tmp/pids/
sudo -u git -H mkdir tmp/sockets/
sudo chmod -R u+rwX tmp/pids/
sudo chmod -R u+rwX tmp/sockets/
# Create public/uploads directory otherwise backup will fail
sudo -u git -H mkdir public/uploads
sudo chmod -R u+rwX public/uploads
# Copy the example Puma config
sudo -u git -H cp config/puma.rb.example config/puma.rb
# Configure Git global settings for git user， useful when editing via web
# Edit user.email according to what is set in gitlab.yml
sudo -u git -H git config --global user.name “GitLab”
sudo -u git -H git config --global user.email “gitlab@localhost”
以上就是CentOS安装配置GitLab的方法介绍了，在安装GitLab前需要配置GitLab环境，需安装安装epel与基础依赖库及软件，再配置GitLab数据库。
