CentOS7下gitlab的搭建

gitlab的搭建

• 安裝基礎包

yum -y install curl policycoreutils openssh-server openssh-clients

 

• 啓動sshd

systemctl enable sshd
systemctl start sshd

 

• 安裝postfix

yum -y install postfix
systemctl enable postfix
systemctl start postfix

 

• 添加防火牆規則

firewall-cmd --permanent --add-service=http
systemctl reload firewalld

 or

yum install firewalld
systemctl unmask firewalld

 

• 下載並安裝軟件包（軟件包下載較慢）

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
yum install gitlab-ce

 

添加國內的鏡像源

執行上面的命令,會一直 time out ,因此咱們要換成國內的源.

如下操做針對CentOS 7 ,其餘的請戳 https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce/

vi /etc/yum.repos.d/gitlab-ce.repo

[gitlab-ce]
name=gitlab-ce
baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
repo_gpgcheck=0
gpgcheck=0
enabled=1
gpgkey=https://packages.gitlab.com/gpg.key

注意,若是對應配置文件下有文件gitlab_gitlab-ce.repo,重命名一下,否則會默認加載這個致使上面的文件不起做用.

查看目前的yum進程,並殺死

ps -a
  PID TTY          TIME CMD
18781 pts/0    00:00:00 sudo
18783 pts/0    00:00:00 bash
18796 pts/0    00:00:00 yum
18855 pts/0    00:00:00 sudo
18856 pts/0    00:00:00 yum
18871 pts/0    00:00:00 ps

kill -9 18796
kill -9 18856

而後安裝:

sudo yum makecache
sudo yum install gitlab-ce 

上面執行完了,是這樣的展現結果

sudo gitlab-ctl reconfigure

gitlab: GitLab should be reachable at http://iZ2851te7e5Z
gitlab: Otherwise configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
gitlab: And running reconfigure again.
gitlab: 
gitlab: For a comprehensive list of configuration options please see the Omnibus GitLab readme
gitlab: https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
gitlab: 
It looks like GitLab has not been configured yet; skipping the upgrade script.
  驗證中      : gitlab-ce-8.7.6-ce.0.el7.x86_64                                                                                         1/1 

已安裝:
  gitlab-ce.x86_64 0:8.7.6-ce.0.el7                                                                                                         

完畢！

 

默認安裝的是最新的gitlab-ce的包，若是須要特定的版本能夠在官網去下載特定的版本 地址：

https://packages.gitlab.com/gitlab/gitlab-ce/

 

• 配置並啓動gitlab

 gitlab-ctl reconfigure

 

• 默認帳戶密碼是

Username: root 
Password: 5iveL!fe

 測試地址(默認80端口):

http://127.0.0.1/

 

二、 gitlab的備份

• 備份命令

gitlab-rake gitlab:backup:create

 

默然的備份目錄爲：    /var/opt/gitlab/backups 備份文件名相似：       1393513186_gitlab_backup.tar

• 備份目錄的修改

vi /etc/gitlab/gitlab.rb
gitlab_rails['backup_path'] = '/mnt/gitlab_backups'

 

三、gitlab數據的恢復或還原

提示：gitlab數據的恢復或者遷移成功的前提——兩臺服務器的gitlab的版本必須相同，若不相同則可能遷移或者恢復失敗

• 將備份文件放在gitlab的默認備份目錄

好比/var/opt/gitlab/backups下的1458217074_gitlab_backup.tar

• 設置自動備份

0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create 

 

• 恢復或者還原

停服務

 gitlab-ctl stop unicorn
 gitlab-ctl stop sidekiq

 

恢復數據

gitlab-rake gitlab:backup:restore BACKUP=1458213020

 

BACKUP後面跟的是備份文件的時間戳，好比恢復備份文件1458217074_gitlab_backup.tar

gitlab-rake gitlab:backup:restore BACKUP=1458217074

 

• 恢復完啓動服務

 gitlab-ctl start

 

gitlab nginx 修改

• 配置文件 /var/opt/gitlab/nginx/conf/gitlab-http.conf。這個文件是gitlab內置的nginx的配置文件，裏面能夠影響到nginx真實監聽端口號。

server {
  listen *:82;

  server_name gitlab.123.123.cn;
  server_tokens off; ## Don't show the nginx version number, a security best practice

• 修改完成後，重啓下，就能夠放82端口的gitlab了。

gitlab-ctl restart

gitlab redis 修改啓用

默認狀況下gitlab是沒有啓用自帶的redis的(雖然redis已經和gitlab一塊兒啓動):

ok: run: gitlab-workhorse: (pid 14263) 1s
ok: run: logrotate: (pid 14271) 0s
ok: run: nginx: (pid 14278) 1s
ok: run: node-exporter: (pid 14284) 0s
ok: run: postgres-exporter: (pid 14288) 1s
ok: run: postgresql: (pid 14303) 0s
ok: run: prometheus: (pid 14312) 1s
ok: run: redis: (pid 14317) 0s
ok: run: redis-exporter: (pid 14320) 0s
ok: run: sidekiq: (pid 14330) 1s
ok: run: unicorn: (pid 14336) 0s

啓用自帶的redis,修改/etc/gitlab/gitlab.rb:

redis['port'] = 6379
redis['bind'] = '127.0.0.1'

[root@localhost ~]# gitlab-ctl reconfigure

能夠看到redis-server和端口6379,redis已經開始工做了:

Running handlers:
Running handlers complete
Chef Client finished, 15/397 resources updated in 25 seconds
gitlab Reconfigured!

[root@localhost ~]# gitlab-ctl restart

[root@localhost ~]# ps -ef|grep redis
root 639 632 0 14:54 ? 00:00:00 runsv redis

root 14376 8935 0 16:36 pts/2 00:00:00 grep --color=auto redis

訪問一下gitlab主頁和各頁面,而後查看redis裏的緩存清況,已經出現緩存內容了:

[root@localhost ~]# /opt/gitlab/embedded/bin/redis-cli
