Git升级迁移

1 原有机器进行升级和备份：

https://about.gitlab.com/update/#centos-6

1. Make a backup (Optional)

If you would like to make a backup before updating, the below command will backup data in /var/opt/gitlab/backups by default.

sudo gitlab-rake gitlab:backup:create STRATEGY=copy


2. Update GitLab

Update to the latest version of GitLab.

sudo yum install -y gitlab-ce

2 新机器上安装社区版：

https://about.gitlab.com/installation/#centos-6?version=ce

3 修改配置文件（可选，为改端口）

1） vim /etc/gitlab/gitlab.rb
#unicorn['port'] = 8080 
-->改为 unicorn['port'] = 8070
#nginx['listen_port'] = nil 
-->改为 nginx['listen_port'] = 5091

2） vim /var/opt/gitlab/gitlab-rails/etc/unicorn.rb

#listen "127.0.0.1:8080", :tcp_nopush => true
--> 改为 listen "127.0.0.1:8070", :tcp_nopush => true

3）vim /var/opt/gitlab/nginx/conf/gitlab-http.conf
#listen *:80;
--> 改为 listen *:5091;

gitlab-ctl reconfigure
gitlab-ctl restart

4 nginx 转发配置（可选）,

新建 gitlab-http.conf 放到独立nginx下

upstream gitlab-workhorse {
  server unix:/var/opt/gitlab/gitlab-workhorse/socket;
}


server {
  listen 80;
  server_name gitlab.xf120.com;

  location / {
    proxy_pass  http://gitlab.xxx.com:5091;
  }
 
}

5 还原

sudo cp xxx_gitlab_backup.tar  /var/opt/gitlab/backups/
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-rake gitlab:backup:restore BACKUP=xxx       注：xxx是第1步备份文件的前缀
sudo gitlab-ctl start
sudo gitlab-rake gitlab:check SANITIZE=true

 6 卸载gitlab

http://www.bubuko.com/infodetail-2310132.html

sudo gitlab-ctl stop

sudo rpm -e gitlab-ce

ps -ef|grep gitlab 会看到如下一个进程

 runsvdir -P /opt/gitlab/service log: ........................................................................
..............................................................................................................
..............................................................................................................
.......................................................................................................

把它kill掉

7 修改邮箱（未验证）

配置smtp邮件发送
$ sudo vi /etc/gitlab/gitlab.rb                            
# Change the external_url to the address your users will type in their browser
external_url 'http://xxhost.com'

#Sending application email via SMTP
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25 
gitlab_rails['smtp_user_name'] = "xxuser@163.com"
gitlab_rails['smtp_password'] = "xxpassword"
gitlab_rails['smtp_domain'] = "163.com"
gitlab_rails['smtp_authentication'] = :login
gitlab_rails['smtp_enable_starttls_auto'] = true

##修改gitlab配置的发信人
gitlab_rails['gitlab_email_from'] = "xxuser@163.com"
user["git_user_email"] = "xxuser@163.com"

 疑难解答：

1）gitlab上传文件大小限制

# 1修改nginx conf(如果使用了nginx转发，转发的nginx和内部nginx都设置一下)
http内添加client_max_body_size

http{
 client_max_body_size 0;
}

# 2 设置postBuffer（服务器和本地上都设一下）
单独项目设置: 
git config http.postBuffer 1024000000
 全局设置：
git config --global http.postBuffer 1024000000

# 3 重启 nginx 和 gitlab 
sudo service nginx restart
sudo gitlab-ctl restart

2）有时候文件过多，下载超时，修改如下：

/var/opt/gitlab/gitlab-rails/etc/unicorn.rb

timeout 600

3) 检查错误

# 检查状态
sudo gitlab-ctl status
