gitlab太占内存，降低gitlab内存占用的配置优化

在新买的阿里云2C4G服务器上部署上了gitlab，启动后服务器竟然死机了，远程都连不上，原因在gitlab太吃内存，我这里使用的是docker部署。启动脚本如下：本文地址:http://www.04007.cn/article/1169.html,未经许可,不得转载.

docker run -d 
    --name gitlab13.3 
    -p 9001:80 
    -v /opt/gitlab13.3/config:/etc/gitlab 
    -v /opt/gitlab13.3/logs:/var/log/gitlab 
    -v /opt/gitlab13.3/data:/var/opt/gitlab 
    gitlab/gitlab-ee:13.3.5-ee.0

要减少gitLab的内存占用，需要修改其配置文件，以上面的配置启动后，gitlab的配置文件 gitlab.rb就在目录/opt/gitlab13.3/config 中。然后我们就可以开始编辑这个配置文件。进行以下修改：

1.减少数据库缓存
postgresql['shared_buffers'] = "64MB"
2.减少数据库并发数
postgresql['max_worker_processes'] = 1
3.减少sidekiq并发数
sidekiq['concurrency'] = 1
4.减少进程数
unicorn['worker_processes'] = 1
nginx['worker_processes'] = 2
5.减少超时时间
unicorn['worker_timeout'] = 10
6.减少数据库缓存
postgresql['shared_buffers'] = "64MB"
7.将worker内存上限设置小一点
unicorn['worker_memory_limit_min'] = "100 * 1 << 20"
unicorn['worker_memory_limit_max'] = "220 * 1 << 20"
8.禁用prometheus
prometheus_monitoring['enable'] = false本文地址:http://www.04007.cn/article/1169.html,未经许可,不得转载.

9关闭一些监控和性能基准相关的功能
prometheus['enable'] = false
prometheus_monitoring['enable'] = false
alertmanager['enable'] = false
node_exporter['enable'] = false
redis_exporter['enable'] = false
postgres_exporter['enable'] = false
pgbouncer_exporter['enable'] = false
gitlab_exporter['enable'] = false
grafana['enable'] = false
sidekiq['metrics_enabled'] = false

docker重载配置生效命令：
重载配置：docker exec -it gitlab容器ID gitlab-ctl reconfigure
重启：docker exec -it gitlab容器ID gitlab-ctl restart

使用以上方式处理后，服务器算是把gitlab运行起来了，但是看了一下，还是吃了不少内存，基本在1.8G内存左右。我也试着去再降低内存占用。网上还有很多可修改配置。但我发现再怎么修改配置，内存占用也没有再减少。仍然在1.7-1.8G。有些提到的可优化配置如下。我这里试过了没什么明显的效果。本文地址:http://www.04007.cn/article/1169.html,未经许可,不得转载.
