    前言

    GitLab：GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭建起来的web服务。
    功能：Gitlab 是一个提供代码托管、提交审核和问题跟踪的代码管理平台。对于软件工程质量管理非常重要。
    版本：GitLab 分为社区版（CE） 和企业版（EE）。
    配置：建议CPU2核，内存2G以上。

    安装

    一、gitlab安装

    1、安装gitlab yum库

    1.安装最新版gitlab-ee（企业版）

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

    2.安装最新版gilab-ce（社区版）

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

    2、安装gitlab

    其中ip为gitlab的访问地址。

    1.企业最新版：

    • EXTERNAL_URL="http://ip" yum install -y gitlab-ee

    2.社区最新版：

    • EXTERNAL_URL="http://ip" yum install -y gitlab-ce

    3.安装指定版本：

    • EXTERNAL_URL="http://ip" yum install -y gitlab-ee-12.1.9-ee.0.el7.x86_64
    • EXTERNAL_URL="http://ip" yum install -y gitlab-ce-12.1.9-ce.0.el7.x86_64

    4.安装完成基本指令：

    查看运行状态

    • gitlab-ctl status

    启动

    • gitlab-ctl start

    停止

    • gitlab-ctl stop

    重启

    • gitlab-ctl restart

    查看版本

    • cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

    重载配置

    • gitlab-ctl reconfigure

    3、访问gitlab

    http://ip 浏览器打开

    gitlab安装、备份、恢复、升级、内存消耗问题

    设置root管理员初始密码。

    设置邮箱及https等请参考原文。

     

    二、gitlab备份、恢复

    1.gitlab备份

    1.设置gitlab备份目录、权限、有限期

     
     
    [root@localhost /]# cat /etc/gitlab/gitlab.rb | grep -v "#"
external_url 'http://192.168.8.127'   //安装设定的访问域名
gitlab_rails['manage_backup_path'] = true
gitlab_rails['backup_path'] = "/data/gitlab/backups"    //备份路径
gitlab_rails['backup_archive_permissions'] = 0644     //备份文件权限
gitlab_rails['backup_keep_time'] = 7776000    //备份文件有效期 30天
     

    2.创建备份路径

     
    [root@localhost /]# mkdir -vp /data/gitlab/backups
mkdir: 已创建目录 "/data"
mkdir: 已创建目录 "/data/gitlab"
mkdir: 已创建目录 "/data/gitlab/backups"

    3.重载配置

    4.开始备份

     
     
     1 [root@localhost /]# gitlab-rake gitlab:backup:create
 2 2019-09-16 11:00:23 +0800 -- Dumping database ...

32 Please back them up manually.
33 Backup task is done.
     

    红字部分表示 gitlab.rb 和 gitlab-secrets.json 两个文件包含敏感信息。未被备份到备份文件中。需要手动备份。

     
     
    1 [root@localhost backups]# pwd
2 /data/gitlab/backups
3 [root@localhost backups]# ls -l
4 总用量 132
5 -rw-r--r-- 1 git git 133120 9月  16 11:00 1568602824_2019_09_16_12.2.5-ee_gitlab_backup.tar
6 [root@localhost backups]#
     

    执行完成后在 /data/gitlab/backups 中生成了备份文件。

    2.gitlab恢复备份

    1.首先停用gitlab的数据连接部分服务

     
     
    [root@localhost backups]# gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up
[root@localhost backups]# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
[root@localhost backups]# gitlab-ctl stop nginx
ok: down: nginx: 0s, normally up
[root@localhost backups]# gitlab-ctl status
run: alertmanager: (pid 30960) 3683s; run: log: (pid 30623) 3735s
run: gitaly: (pid 30846) 3685s; run: log: (pid 30081) 3828s
run: gitlab-monitor: (pid 30843) 3685s; run: log: (pid 30498) 3753s
run: gitlab-workhorse: (pid 30820) 3686s; run: log: (pid 30349) 3784s
run: grafana: (pid 30980) 3682s; run: log: (pid 30750) 3698s
run: logrotate: (pid 37253) 178s; run: log: (pid 30384) 3777s
down: nginx: 4s, normally up; run: log: (pid 30368) 3781s
run: node-exporter: (pid 30830) 3685s; run: log: (pid 30418) 3764s
run: postgres-exporter: (pid 30971) 3683s; run: log: (pid 30650) 3730s
run: postgresql: (pid 30127) 3825s; run: log: (pid 30139) 3821s
run: prometheus: (pid 30943) 3684s; run: log: (pid 30588) 3741s
run: redis: (pid 29960) 3838s; run: log: (pid 29972) 3835s
run: redis-exporter: (pid 30854) 3684s; run: log: (pid 30522) 3747s
down: sidekiq: 13s, normally up; run: log: (pid 30324) 3788s
down: unicorn: 17s, normally up; run: log: (pid 30307) 3792s
     

    2.执行恢复

    远程复制的备份需要  chmod 777 1568602824_2019_09_16_12.2.5-ee.....   赋予权限

     
     
     1 [root@localhost backups]# gitlab-rake gitlab:backup:restore BACKUP=1568602824_2019_09_16_12.2.5-ee
 2 Unpacking backup ... done
 3 Before restoring the database, we will remove all existing
 4 tables to avoid future upgrade problems. Be aware that if you have
 5 custom tables in the GitLab database these tables and all data will be
 6 removed.
 7 ……………………………………
 8 Do you want to continue (yes/no)? yes
 9 This task will now rebuild the authorized_keys file.
10 You will lose any data stored in the authorized_keys file.
11 Do you want to continue (yes/no)? yes
12 
13 Deleting tmp directories ... done
14 done
15 done
16 done
17 done
18 done
19 done
20 done
21 Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data 
22 and are not included in this backup. You will need to restore these files manually.
23 Restore task is done.
     

    备份tar包一定要放到备份路径下。恢复是删除原有数据，恢复备份tar包中的数据。

    如果是在其他服务器恢复备份，一定要记得将 gitlab.rb 和 gitlab-secrets.json 手动复制到相应路径下。

    gitlab.rb路径：/etc/gitlab/gitlab.rb

    gitlab-secrets.json路径：/etc/gitlab/gitlab-secrets.json

    3.重载配置 

    • gitlab-ctl reconfigure

    4.重启gitlab，check检查

     
     
     1 [root@localhost backups]# gitlab-ctl restart
 2 ok: run: alertmanager: (pid 30960) 3785s
 3 ok: run: gitaly: (pid 30846) 3787s
 4 ok: run: gitlab-monitor: (pid 30843) 3787s
 5 ok: run: gitlab-workhorse: (pid 30820) 3788s
 6 ok: run: grafana: (pid 30980) 3784s
 7 ok: run: logrotate: (pid 37253) 280s
 8 ok: run: nginx: (pid 37535) 0s
 9 ok: run: node-exporter: (pid 30830) 3787s
10 ok: run: postgres-exporter: (pid 30971) 3785s
11 ok: run: postgresql: (pid 30127) 3927s
12 ok: run: prometheus: (pid 30943) 3786s
13 ok: run: redis: (pid 29960) 3940s
14 ok: run: redis-exporter: (pid 30854) 3786s
15 ok: run: sidekiq: (pid 37547) 1s
16 ok: run: unicorn: (pid 37553) 0s
17 [root@localhost backups]# gitlab-rake gitlab:check SANITIZE=true

    ok，至此恢复完成

    三、gitlab版本升级

    1.停止数据传输服务

     
     
     1 [root@localhost backups]# gitlab-ctl stop unicorn
 2 ok: down: unicorn: 0s, normally up
 3 [root@localhost backups]# gitlab-ctl stop sidekiq
 4 ok: down: sidekiq: 0s, normally up
 5 [root@localhost backups]# gitlab-ctl stop nginx
 6 ok: down: nginx: 1s, normally up
 7 [root@localhost backups]# gitlab-ctl status
 8 run: gitaly: (pid 73164) 939s; run: log: (pid 72843) 968s
 9 run: gitlab-monitor: (pid 73232) 938s; run: log: (pid 73021) 957s
10 run: gitlab-workhorse: (pid 75742) 136s; run: log: (pid 72919) 962s
11 run: logrotate: (pid 72985) 960s; run: log: (pid 72984) 960s
12 down: nginx: 5s, normally up; run: log: (pid 72960) 961s
13 run: node-exporter: (pid 73003) 959s; run: log: (pid 73002) 959s
14 run: postgres-exporter: (pid 73253) 937s; run: log: (pid 73086) 948s
15 run: postgresql: (pid 72644) 997s; run: log: (pid 72643) 997s
16 run: prometheus: (pid 73241) 938s; run: log: (pid 73064) 950s
17 run: redis: (pid 72598) 1003s; run: log: (pid 72597) 1003s
18 run: redis-exporter: (pid 73048) 951s; run: log: (pid 73047) 951s
19 down: sidekiq: 7s, normally up; run: log: (pid 72818) 974s
20 down: unicorn: 10s, normally up; run: log: (pid 72778) 976s
     

    2.下载最新的ce/ee rpm包（清华源https://mirrors.tuna.tsinghua.edu.cn/gitlab-ee/yum/el7/ 或者https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/）

    • wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ee/yum/el7/gitlab-ee-12.2.5-ee.0.el7.x86_64.rpm

    gitlab10.0.0版本升级最新版本需要先升级到11.11.0，再升级12.2.5！

    gitlab安装、备份、恢复、升级、内存消耗问题

    3.升级ce/ee

    • rpm -Uvh gitlab-ee-12.2.5-ee.0.el7.x86_64.rpm

    4.重载配置

    • gitlab-ctl reconfigure

    5.重启gitlab

    • gitlab-ctl restart

    四、gitlab解决内存消耗问题

     
     
     
     1 [root@storage100 backups]# cat /etc/gitlab/gitlab.rb | grep -v "#"
 2 #进程超时时间
 3 unicorn['worker_timeout'] = 60
 4 #进程数
 5 unicorn['worker_processes'] = 10
 6 #进程最小内存
 7 unicorn['worker_memory_limit_min'] = "200 * 1 << 20"
 8 #进程最大内存
 9 unicorn['worker_memory_limit_max'] = "300 * 1 << 20"
10 #并发数
11 sidekiq['concurrency'] = 16
12 #数据库缓存
13 postgresql['shared_buffers'] = "256MB"
14 #数据库并发数
15 postgresql['max_worker_processes'] = 8
     

     

     

     

     

     

     

     

     

    附gitlab备份脚本：

     
     
    #!/bin/bash
