源码安装GitLab

GitLab是由GitLab Inc.开发，使用MIT许可证的基于网络的Git仓库管理工具，且具有wiki和issue跟踪功能。

安装要求

系统为Ubuntu 20，内存至少4G，建议增加Swap交换分区解决内存不足等问题。

1.安装软件包及依赖

安装vim编辑器并设置为默认编辑器

1 2	apt-get install -y vim update-alternatives --set editor /usr/bin/vim.basic

安装依赖

apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libre2-dev libreadline-dev libncurses5-dev libffi-dev curl openssh-server libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev logrotate rsync python-docutils pkg-config cmake runit-systemd

从GitLab13.6起，需要安装Gitaly提供的Git。

apt-get install -y libcurl4-openssl-dev libexpat1-dev gettext libz-dev libssl-dev libpcre2-dev build-essential git-core
git clone https://gitlab.com/gitlab-org/gitaly.git -b <X-Y-stable> /tmp/gitaly
cd /tmp/gitaly
make git GIT_PREFIX=/usr/local

为了使自定义图标能够正常工作，需要安装GraphicsMagick。

1	apt-get install -y graphicsmagick

为了接收邮件通知，需要安装postfix。

1	apt-get install -y postfix

2.Ruby

运行GitLab需要使用Ruby，需要安装Ruby。


# 下载Ruby源码并编译安装
mkdir /tmp/ruby && cd /tmp/ruby
curl --remote-name --progress-bar "https://cache.ruby-lang.org/pub/ruby/2.7/ruby-2.7.4.tar.gz"
echo '3043099089608859fc8cce7f9fdccaa1f53a462457e3838ec3b25a7d609fbc5b ruby-2.7.4.tar.gz' | sha256sum -c - && tar xzf ruby-2.7.4.tar.gz
cd ruby-2.7.4
./configure --disable-install-rdoc --enable-shared
make
make install

3.Go

GitLab有几个用Go编写的守护程序。要安装GitLab，需要一个Go编译器。

# 如果有旧的Go编译器的话，需要先移除掉旧版本
rm -rf /usr/local/go

curl --remote-name --progress-bar "https://golang.org/dl/go1.16.9.linux-amd64.tar.gz"
echo 'd2c095c95f63c2a3ef961000e0ecb9d81d5c68b6ece176e2a8a2db82dc02931c' go1.16.9.linux-amd64.tar.gz' | shasum -a256 -c - && sudo tar -C /usr/local -xzf go1.15.12.linux-amd64.tar.gz
ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
rm go1.16.9.linux-amd64.tar.gz

4.Node

GitLab需要使用Node来编译JavaScript，并使用Yarn来管理JavaScript依赖。

# 安装node v14.x
curl --location "https://deb.nodesource.com/setup_14.x" | sudo bash -
apt-get install -y nodejs
npm install --global yarn

5.添加GitLab用户

为GitLab创建一个git用户。

1	adduser --disabled-login --gecos 'GitLab' git

6.数据库

创建PostgreSQL数据库

1	apt-get install -y postgresql postgresql-client libpq-dev postgresql-contrib

启动PostgreSQL数据库并查看状态

1 2	service postgresql start service postgresql status

为GitLab创建数据库用户

1	sudo -u postgres psql -d template1 -c "CREATE USER git CREATEDB;"

创建pg_trgm扩展

1	sudo -u postgres psql -d template1 -c "CREATE EXTENSION IF NOT EXISTS pg_trgm;"

创建btree_gist扩展

1	sudo -u postgres psql -d template1 -c "CREATE EXTENSION IF NOT EXISTS btree_gist;"

创建数据库并赋予用户权限

1	sudo -u postgres psql -d template1 -c "CREATE DATABASE gitlabhq_production OWNER git;"

尝试使用git用户连接数据库

1	sudo -u git -H psql -d gitlabhq_production

检查扩展pg_trgm是否生效

SELECT true AS enabled
FROM pg_available_extensions
WHERE name = 'pg_trgm'
AND installed_version IS NOT NULL;

如果扩展生效，则显示以下内容

enabled
---------
 t
(1 row)

检查扩展btree_gist是否生效

SELECT true AS enabled
FROM pg_available_extensions
WHERE name = 'btress_gist'
AND installed_version IS NOT NULL;

如果扩展生效，则显示以下内容

enabled
---------
 t
(1 row)

退出数据库

1	gitlabhq_production> \q

修改Postgresql的配置文件允许机器访问

vim /etc/postgresql/12/main/pg_hba.conf

# 修改文件末尾处
# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust

重启PostgreSQL服务。

7.Redis

GitLab需要安装Redis。

1	apt-get install redis-server

配置Redis

cp /etc/redis/redis.conf /etc/redis/redis.conf.orig

sed 's/^port .*/port 0/' /etc/redis/redis.conf.orig | tee /etc/redis/redis.conf

echo 'unixsocket /var/run/redis/redis.sock' | tee -a /etc/redis/redis.conf

echo 'unixsocketperm 770' | tee -a /etc/redis/redis.conf

mkdir -p /var/run/redis
chown redis:redis /var/run/redis
chmod 755 /var/run/redis

if [ -d /etc/tmpfiles.d ]; then
  echo 'd  /var/run/redis  0755  redis  redis  10d  -' | tee -a /etc/tmpfiles.d/redis.conf
fi

service redis-server restart

usermod -aG redis git
