在Linux上實現GitLab的高可用性架構通常涉及以下幾個關鍵步驟:
硬件和網絡準備:
安裝GitLab:
# 使用Docker安裝
docker pull gitlab/gitlab-ce:latest
docker run --detach \
--hostname gitlab.example.com \
--publish 80:80 \
--publish 443:443 \
--publish 2222:22 \
--name gitlab \
--restart always \
--volume /srv/gitlab/config:/etc/gitlab \
--volume /srv/gitlab/logs:/var/log/gitlab \
--volume /srv/gitlab/data:/var/opt/gitlab \
gitlab/gitlab-ce:latest
配置負載均衡器:
upstream gitlab {
server gitlab1.example.com;
server gitlab2.example.com;
server gitlab3.example.com;
}
server {
listen 80;
server_name gitlab.example.com;
location / {
proxy_pass http://gitlab;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
配置GitLab實例:
/etc/gitlab/gitlab.rb 文件,設置不同的實例ID:external_url 'http://gitlab1.example.com'
unicorn['listen_address'] "0.0.0.0:8080"
gitlab_rails['lfs_enabled'] true
gitlab_rails['gitlab_shell_ssh_port'] 2222
external_url 'http://gitlab2.example.com'
unicorn['listen_address'] "0.0.0.0:8081"
gitlab_rails['lfs_enabled'] true
gitlab_rails['gitlab_shell_ssh_port'] 2223
external_url 'http://gitlab3.example.com'
unicorn['listen_address'] "0.0.0.0:8082"
gitlab_rails['lfs_enabled'] true
gitlab_rails['gitlab_shell_ssh_port'] 2224
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
配置數據庫和緩存:
sudo apt-get install postgresql postgresql-contrib
sudo systemctl start postgresql
sudo systemctl enable postgresql
CREATE DATABASE gitlabhq_production;
CREATE USER gitlab WITH ENCRYPTED PASSWORD 'your_password';
GRANT ALL PRIVILEGES ON DATABASE gitlabhq_production TO gitlab;
sudo apt-get install redis-server
sudo systemctl start redis-server
sudo systemctl enable redis-server
配置GitLab Shell:
sudo gitlab-ctl start gitlab-shell
測試高可用性:
通過以上步驟,可以在Linux上實現GitLab的高可用性配置。這只是一個基本的指南,實際部署可能需要根據具體需求進行調整。
