1.安装配置必须的依赖
yum install curl policycoreutils openssh-server openssh-clients
systemctl enable sshd
systemctl start sshd
yum install postfix
systemctl enable postfix
systemctl start postfix
firewall-cmd --permanent --add-service=http
systemctl reload firewalld
2.安装gitlab
rpm -ivh gitlab-ce-8.11.6-ce.0.el6.x86_64.rpm
3.配置并启动gitlab
gitlab-ctl reconfigure
4.默认账户密码
Username: root
Password: 5iveL!fe
5.备份
gitlab-rake gitlab:backup:create
默然的备份目录为： /var/opt/gitlab/backups
修改备份目录
vi /etc/gitlab/gitlab.rb
gitlab_rails['backup_path'] = '/mnt/gitlab_backups'
6.数据恢复和还原
停止服务
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
BACKUP后面跟的是备份文件的时间戳，比如恢复备份文件1458217074_gitlab_backup.tar，注：需要恢复的文件必须放在gitlib的备份目录下
gitlab-rake gitlab:backup:restore BACKUP=1458213020
恢复完成启动服务
gitlab-ctl start/restart
以上gitlab基本搭建完成 网页直接IP访问 默认端口为80
#修改默认端口
1.Change port to 81 (You can choose your own) at port: near by production:$base >> gitlab: for file /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml
2.Change your host address if you like to use different from your ip address or localhost
3.Change server port to 81 in file "/opt/gitlab/embedded/conf/nginx.conf"
4.Restart gitlab using command "sudo gitlab-ctl restart".
5.Open "/etc/gitlab/gitlab.rb" to text editor where currently I have external_url 'http://myipaddress/' as text. I just change to
external_url 'http://gitlab.com.local:81/'
then reconfigure using command "sudo gitlab-ctl reconfigure" and voila, Gitlab is now working on port 81.
#开机自启动
systemctl enable gitlab-runsvdir.service
systemctl start gitlab-runsvdir.service
gitlab-cmd start
