[安裝 Ruby]

# using RVM to install Ruby
# install RVM in system wide

su - 

curl -L get.rvm.io | bash -s stable
source ~/.bash_profile
rvm requirements
rvm install 1.9.2
rvm use 1.9.2 --default

which ruby
which gem

[設定 Gitolite]

adduser -r -s /bin/sh -c 'git version control' -U -m git
adduser -c 'gitlab system' -U -m gitlab

usermod -a -G git gitlab
usermod -a -G rvm gitlab
usermod -a -G rvm git

chmod 755 /home/git
chmod 755 /home/gitlab

logout & login

sudo -H -u gitlab ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa
sudo -H -u git git clone http://github.com/gitlabhq/gitolite /home/git/gitolite

sudo -u git sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" > /home/git/.profile'
sudo -u git -i -H /home/git/gitolite/src/gl-system-install
cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
chmod 777 /home/git/gitlab.pub

sudo -u git -H sed -i 's/0077/0007/g' /home/git/share/gitolite/conf/example.gitolite.rc
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gl-setup -q /home/git/gitlab.pub"

chmod -R g+rwX /home/git/repositories/
chown -R git:git /home/git/repositories/

# check if gitolite works
# If you CAN NOT clone gitolite-admin repository - DONT PROCEED INSTALLATION
su - gitlab
git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin
rm -rf /tmp/gitolite-admin 
exit

[設定 Gitlab]

gem install charlock_holmes
gem install bundler

su - gitlab

cd /home/gitlab
git clone http://github.com/gitlabhq/gitlabhq.git gitlab

cd gitlab
cp config/gitlab.yml.example config/gitlab.yml # using default website setting
cp config/database.yml.sqlite config/database.yml # using SQLite as database

bundle install --without development test --deployment

bundle exec rake gitlab:app:setup RAILS_ENV=production
bundle exec rake gitlab:app:status RAILS_ENV=production

bundle exec rake environment resque:work QUEUE=* RAILS_ENV=production BACKGROUND=yes
bash /home/gitlab/gitlab/resque.sh

bundle exec rails s -e production # test running
bundle exec rails s -e production -d # test running as a daemon

[設定 Nginx]

yum install nginx

su - gitlab
cd ~/gitlab
cp config/unicorn.rb.orig config/unicorn.rb
bundle exec unicorn_rails -c config/unicorn.rb -E production -D

exit

編輯 /etc/nginx/nginx.conf,在 http { 後加入以下內容:

# 注意修改 YOUR_SERVER_IP 與 YOUR_SUBDOMAIN

upstream gitlab {
    server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.socket;
}

server {
    listen YOUR_SERVER_IP:80;
    server_name YOUR_DOMAIN;
    root /home/gitlab/gitlab/public;

    # individual nginx logs for this gitlab vhost
    access_log  /var/log/nginx/gitlab_access.log;
    error_log   /var/log/nginx/gitlab_error.log;

    location / {
    # serve static files from defined root folder;.
    # @gitlab is a named location for the upstream fallback, see below
    try_files $uri $uri/index.html $uri.html @gitlab;
    }

    # if a file, which is not found in the root folder is requested, 
    # then the proxy pass the request to the upsteam (gitlab unicorn)
    location @gitlab {
      proxy_redirect     off;
      # you need to change this to "https", if you set "ssl" directive to "on"
      proxy_set_header   X-FORWARDED_PROTO http;
      proxy_set_header   Host              YOUR_SUBDOMAIN:80;
      proxy_set_header   X-Real-IP         $remote_addr;

      proxy_pass http://gitlab;
    }

}

編輯 /etc/init.d/gitlab

exit 0

避免 SSH 主機信任問題

su - gitlab
ssh git@YOUR_DOMAIN

The authenticity of host 'YOUR_DOMAIN (YOUR_IP)' can't be established.  
RSA key fingerprint is 98:2e:d7:e0:de:9f:ac:67:28:c2:42:2d:37:16:58:4d.
Are you sure you want to continue connecting (yes/no)? 

# 回答 yes 表示信任該主機

注意!目前 Gitlab 有一個 README 顯示 utf8 的 bug

測試啓動

chmod +x /etc/init.d/gitlab
/etc/init.d/nginx restart
/etc/init.d/gitlab restart

設定開機啓動

yum install postfix
chkconfig postfix on
chkconfig nginx on
echo "/etc/init.d/gitlab start" >> /etc/rc.local
