Centos6安装Gitlab

参考 https://about.gitlab.com/downloads/ 可以从清华的镜像下载安装包, 注意区分自己用的是哪个发行版 https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce/

1. iptables打开80端口

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

2. 安装依赖包

yum install curl openssh-server openssh-clients postfix cronie

3. 启动postfix服务, 并设为默认开启

service postfix start
chkconfig postfix on

4. 安装gitlab

rpm -i gitlab-ce-8.10.2-ce.0.el6.x86_64.rpm 
# 安装结束后初始化配置 gitlab
gitlab-ctl reconfigure

5. 访问后发现会重定向回 http://localhost, 需要修改external_url

vi /etc/gitlab/gitlab.rb 
# 然后修改 external_url 'http://192.168.11.22'
# 然后reconfigure
gitlab-ctl reconfigure

安装就完成了

备份

查看/etc/gitlab/gitlab.rb里的配置信息

# gitlab_rails['manage_backup_path'] = true
# gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"
# gitlab_rails['backup_archive_permissions'] = 0644 # See: http://doc.gitlab.com/ce/raketasks/backup_restore.html#backup-archive-permissions
# gitlab_rails['backup_pg_schema'] = 'public'
# gitlab_rails['backup_keep_time'] = 604800

这是默认的备份配置, 需要检查一下默认的备份路径是否存在, 以及owner是否是git. 创建备份的命令很简单, 就是

gitlab-rake gitlab:backup:create

会依次导出postgresql, repository 和 uploads, 然后打成一个压缩包

恢复时备份文件必须在 /var/opt/gitlab/backups路径下, 命令

#gitlab-rake gitlab:backup:restore BACKUP=备份文件编号
gitlab-rake gitlab:backup:restore BACKUP=1502357536_2017_08_10_9.4.3

命令行重置root密码

在命令行下运行

# 切换到git用户
su - git
# 进入gitlab console
-sh-4.1$ gitlab-rails console production
Loading production environment (Rails 4.2.7)
# 令user为root用户
irb(main):001:0> user = User.where(id:1).first
=> #<User id: 1, email: "[email protected]", encrypted_password: ... 
...
# 输入新密码
irb(main):002:0> user.password='passwd.2016'
=> "passwd.2016"
# 保存新密码
irb(main):003:0> user.save!
=> true
# 退出
irb(main):004:0> exit
-sh-4.1$ exit
logout

升级Gitlab版本

在12.x.x之前, 跨大版本升级可以升级到大版本下的最后一个版本, 例如 8.10.2 -> 8.17.8, -> 9.5.10 -> 10.8.7 -> 11.11.8

在12.x.x之后, 不能直接升级到最后版本了, 每次要先升级到大版本的第一个小版本, 再继续升到这个大版本下的最后一个版本, 例如 11.11.8 -> 12.0.12 -> 12.10.14 -> 13.0.14

升级的命令

# 停止服务
sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx

# 升级, 此时会自动处理migration和pgresql升级
sudo dpkg -i gitlab-ce_12.0.12-ce.0_amd64.deb 
# 根据上一步的提示, restart服务
sudo gitlab-ctl restart

虽然官方提示从8.10.2先要升到8.12.0才能继续升到8.17.7, 但是实际测试直接升到8.17.8也没问题.

在8.x.x升到最高版本的过程中, 会遇到"Permission error 0700 not 2770", "Failed asserting that mode permissions on "/mnt/AZLSERV/git-data/repositories" is 2770"的错误, 这时候运行一下

chmod -R 2770 /var/opt/gitlab/git-data/repositories

再运行 gitlab-ctl reconfigure就可以了

# This will take a while
gitlab-ctl reconfigure

# Install docker
apt install docker.io

# Add user, you must add with -m and -s /bin/bash milton, this is a bit weird in Aliyun Ubuntu
useradd milton -m

对应的Dockerfile和setup.sh

如果需要Gitlab Runner优先使用本地docker上的image, 需要修改其配置, 位于/etc/gitlab-runner/config.toml , 增加pull_policy = "if-not-present" 注意有双引号

[[runners]]
  name = "Ubuntu 18.04 x64 runner"
  url = "http://172.17.54.19/"
  token = "UsJyRYap61AxbJ3pY_in"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
  [runners.docker]
    tls_verify = false
    image = "ubuntu_bionic_runner:1.0"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
    pull_policy = "if-not-present"
