Migrate Bitnami Gitlab to another server

原來裝的 Bitnami Gitlab Virtual Machine是 Gitlab 6.8，因為我手賤升級Ubuntu就不太正常，要把原來的Gitlab升級。

先看了GitLab Upgrader發覺不太夠，再看6.9 to 7.0，確認 Ruby版本也要新版，於是抓了新版的 Bitnami Gitlab Virtual Machine，打算直接連OS一併升級。


Bitnami原廠的升級步驟在這裡，但是不完全足夠，所以我整理成一篇筆記。

我會利用到ssh，所以必須啟動ssh

sudo mv /etc/init/ssh.conf.back /etc/init/ssh.conf
sudo service ssh start

首先要知道 mysql的密碼，root預設是 bitnami1。至於bitnami的mysql密碼則要看database.yml
grep password /opt/bitnami/apps/gitlab/htdocs/config/database.yml
先用bitnami登入
sudo su -
cd /opt/bitnami
./use_gitlab
export PATH_TO_BACKUP=/opt/backup
cd /opt/bitnami
sudo ./use_gitlab

if [ ! -d $PATH_TO_BACKUP ]
then
   mkdir $PATH_TO_BACKUP
fi


cd /opt/bitnami/mysql/bin/
mysqldump -u bitnami -p bitnami_gitlab > $PATH_TO_BACKUP/bitnami_gitlab_bk.sql
mysqldump -u bitnami -p bitnami_gitlabci > $PATH_TO_BACKUP/bitnami_gitlabci_bk.sql
if [ ! -d $PATH_TO_BACKUP/git ]
then
   mkdir $PATH_TO_BACKUP/git
fi
if [ ! -d $PATH_TO_BACKUP/gitlab_ci ]
then
   mkdir $PATH_TO_BACKUP/gitlab_ci
fi

cp -r /home/git/.ssh $PATH_TO_BACKUP/git/.ssh
cp -r /home/gitlab_ci/.ssh $PATH_TO_BACKUP/gitlab_ci/.ssh
cd /opt/bitnami/apps/gitlab
tar czf $PATH_TO_BACKUP/repositories.tgz repositories
cd /opt/bitnami/apps/gitlabci/conf
tar czf $PATH_TO_BACKUP/certs.tgz certs


備份完成後，到新建好的VM，查出bitnami的mysql密碼 (同樣是利用 grep password /opt/bitnami/apps/gitlab/htdocs/config/database.yml )
同樣要啟動ssh
sudo mv /etc/init/ssh.conf.back /etc/init/ssh.conf
sudo service ssh start
接著
sudo su -
scp -r  root@舊的server:/opt/backup /opt

grep password /opt/bitnami/apps/gitlab/htdocs/config/database.yml
/opt/bitnami/ctlscript.sh stop
/opt/bitnami/ctlscript.sh start mysql
/opt/bitnami/use_gitlab
mysql -u root -p


drop database bitnami_gitlab;
drop database bitnami_gitlabci;
create database bitnami_gitlab;
create database bitnami_gitlabci;
grant all privileges on bitnami_gitlab.* to 'bitnami'@'localhost' identified by 'bitnami密碼';
grant all privileges on bitnami_gitlab.* to 'gitlab'@'localhost' identified by 'bitnami密碼';
grant all privileges on bitnami_gitlabci.* to 'bitnami'@'localhost' identified by 'bitnami密碼';
grant all privileges on bitnami_gitlabci.* to 'gitlab'@'localhost' identified by 'bitnami密碼';
flush privileges;

\q

export PATH_TO_BACKUP=/opt/backup
mysql -u root -pbitnami1 bitnami_gitlab < $PATH_TO_BACKUP/bitnami_gitlab_bk.sql
mysql -u root -pbitnami1  bitnami_gitlabci < $PATH_TO_BACKUP/bitnami_gitlabci_bk.sql
cp -r $PATH_TO_BACKUP/git /home
cp -r $PATH_TO_BACKUP/gitlab_ci /home
cd /opt/bitnami/apps/gitlab
tar xzf  $PATH_TO_BACKUP/repositories.tgz
cd /opt/bitnami/apps/gitlabci/conf
tar xzf $PATH_TO_BACKUP/certs.tgz
chown -Rf git:git /home/git/.ssh
chown -Rf gitlab_ci:gitlab_ci /home/gitlab_ci/.ssh
hown -Rf gitlab_ci:gitlab_ci /opt/bitnami/apps/gitlabci/conf/certs
cd /opt/bitnami/apps/gitlab/htdocs
 sudo -u git -H bundle install --deployment --without development test postgres --binstubs
cd /opt/bitnami/apps/gitlabci/htdocs
 sudo -u git -H ruby bin/rake db:migrate RAILS_ENV=production
cd /opt/bitnami/apps/gitlab/htdocs
 sudo -u git -H ruby bin/rake db:migrate migrate_iids RAILS_ENV=production
/opt/bitnami/ctlscript.sh restart
 sudo -u git -H ruby bin/rake assets:clean assets:precompile cache:clear RAILS_ENV=production
/opt/bitnami//ctlscript.sh restart

萬一遇到問題，再用這招
cd /opt/bitnami/apps/gitlab/htdocs
sudo -u git -H ruby bin/rake gitlab:check RAILS_ENV=production


我的步驟是做了
sudo chmod u+rwx,g=rx,o-rwx /opt/bitnami/apps/gitlab/gitlab-satellites

cd /opt/bitnami/apps/gitlab/htdocs
sudo -u git -H /opt/bitnami/apps/gitlab/gitlab-shell/bin/create-hooks

最後再用這招檢查，沒問題再重啟apache
cd /opt/bitnami/apps/gitlab/htdocs
sudo -u git -H ruby bin/rake gitlab:check RAILS_ENV=production

同場加映：修改Ubuntu 14.04 hostname與 改為固定IP

改hostname很簡單

sudo vi /etc/hostname

接下來改固定IP
sudo vi /etc/network/interfaces

把原本的iface eth0 inet dhcp 改成

iface eth0 inet static

address  192.168.1.111[你的IP]

netmask 255.255.255.0[你的netmask]

gateway 192.168.1.254[你的gateway]

network 192.168.1.0[你的network]

broadcast  192.168.1.255[你的broadcast]

dns-nameservers 8.8.8.8 8.8.4.4

VMware現在推薦使用open-vm-tools instead of VMware Tools for Linux，所以：

sudo apt-get install open-vm-tools

改完hostname後，再去改 /opt/bitnami/apps/gitlab/htdocs/config/gitlab.yml ，將host: 後面的IP改成hostname。但是只要重開機或重新執行/opt/bitnami/ctlscript.sh後 在gitlab的 hostname 還是會變成IP，所以完成後要刪掉Bitnami做的 /opt/bitnami/apps/gitlab/bnconfig ，才不會一直改 gitlab.yml。

改好後，只要 sudo /opt/bitnami/apache2/bin/apachectl restart 就會生效。
