CentOS7下gitlab的搭建

gitlab的搭建

安装基础包

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

启动sshd

systemctl enable sshd

systemctl start sshd

安装postfix

yum -y install postfix

systemctl enable postfix

systemctl start postfix

添加防火墙规则

firewall-cmd --permanent --add-service=http

systemctl reload firewalld

yum install firewalld

systemctl unmask firewalld

下载并安装软件包（软件包下载较慢）

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

yum install gitlab-ce

添加国内的镜像源

执行上面的命令,会一直 time out ,所以我们要换成国内的源.

以下操作针对CentOS 7 ,其他的请戳 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,如果对应配置文件下有文件gitlab_gitlab-ce.repo,重命名一下,不然会默认加载这个导致上面的文件不起作用.

查看目前的yum进程,并杀死

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

然后安装:

sudo yum makecache

sudo yum install gitlab-ce

上面执行完了,是这样的展示结果

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.

  验证中      : gitlab-ce-8.7.6-ce.0.el7.x86_64                                                                                         1/1 

已安装:

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

完毕！

默认安装的是最新的gitlab-ce的包，如果需要特定的版本可以在官网去下载特定的版本地址：

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

配置并启动gitlab

 gitlab-ctl reconfigure

默认账户密码是

Username: root

Password: 5iveL!fe

测试地址(默认80端口):

http://127.0.0.1/

2、 gitlab的备份

备份命令

gitlab-rake gitlab:backup:create

默然的备份目录为： /var/opt/gitlab/backups 备份文件名类似： 1393513186_gitlab_backup.tar

vi /etc/gitlab/gitlab.rb

gitlab_rails['backup_path'] = '/mnt/gitlab_backups'

3、gitlab数据的恢复或还原

提示：gitlab数据的恢复或者迁移成功的前提——两台服务器的gitlab的版本必须相同，若不相同则可能迁移或者恢复失败

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

设置自动备份

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

恢复或者还原

停服务

 gitlab-ctl stop unicorn

 gitlab-ctl stop sidekiq

恢复数据

gitlab-rake gitlab:backup:restore BACKUP=1458213020

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

gitlab-rake gitlab:backup:restore BACKUP=1458217074

恢复完启动服务

 gitlab-ctl start

gitlab nginx 修改

配置文件 /var/opt/gitlab/nginx/conf/gitlab-http.conf。这个文件是gitlab内置的nginx的配置文件，里面可以影响到nginx真实监听端口号。

server {

  listen *:82;

  server_name gitlab.123.123.cn;

  server_tokens off; ## Don't show the nginx version number, a security best practice

修改完成后，重启下，就可以放82端口的gitlab了。

gitlab-ctl restart

gitlab redis 修改启用

默认情况下gitlab是没有启用自带的redis的(虽然redis已经和gitlab一起启动):

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

启用自带的redis,修改/etc/gitlab/gitlab.rb:

redis['port'] = 6379

redis['bind'] = '127.0.0.1'

[root@localhost ~]# gitlab-ctl reconfigure

可以看到redis-server和端口6379,redis已经开始工作了:

Running handlers:

gitlab Reconfigured!

[root@localhost ~]# gitlab-ctl restart

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

访问一下gitlab主页和各页面,然后查看redis里的缓存清况,已经出现缓存内容了:

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