系统环境描述
System information System: Ubuntu 14.04 Current User: git Using RVM: no Ruby Version: 2.1.5p273 Gem Version: 2.2.1 Bundler Version:1.5.3 Rake Version: 10.3.2 Sidekiq Version:3.3.0 GitLab information Version: 7.8.1 Revision: e2d785c Directory: /opt/gitlab/embedded/service/gitlab-rails DB Adapter: postgresql URL: https://git.zhuima.com HTTP Clone URL: https://git.zhuima.com/some-project.git SSH Clone URL: ssh://git@git.zhuima.com:10086/zhuima.git Using LDAP: yes Using Omniauth: no GitLab Shell Version: 2.5.4 Repositories: /data/gitlab/data/repositories Hooks: /opt/gitlab/embedded/service/gitlab-shell/hooks/ Git: /opt/gitlab/embedded/bin/git
问题症状
每天总有一段时间会出现403的情况 办公网不能访问位
拍错思路
1、日志中出现401、403状态吗
2、gitlab-rake gitlab:check发现的问题 [修复未能解决问题]
zhuima-library / yii-framework ... no Try fixing it: sudo -u git -H bundle exec rake gitlab:satellites:create RAILS_ENV=production If necessary, remove the tmp/repo_satellites directory ... ... and rerun the above command For more information see: doc/raketasks/maintenance.md
3、网上的文档搜索相关文档
http://boardreader.com/thread/Gitlab_7_10_4_Forbidden_Error_56o55lX769.html 怀疑是rack_attack.rb文件的策略导致的，修改文件,重启不生效
rack_attack.rb文件的额配置，修改1s并发300不生效！！！！！
unless Rails.env.test?
Rack::Attack.throttle('protected paths', limit: 300, period: 1.seconds) do |req|
if req.post? && req.path =~ paths_regex
req.ip
end
end
end
其他
每次服务中断时间为1小时
该时间段内没有设置任务计划 gitlab是通过ladp进行账号验证的
仅仅办公网不能正常访问gitlab，外部网络访问正常
1、仅仅办公网不能正常访问gitlab，外部网络访问正常 2、办公网络开发人数150+ 3、并发30+
需要解决的问题
想要的效果
1、如何禁用rack_attack.rb的策略 2、稳定的服务

排错过程中所做的操作
1_settings.rb中定义的
1_settings.rb中添加白名单，生效，但是gitlab-ctl reconfigure之后配置被初始化
Settings['rack_attack'] ||= Settingslogic.new({})
Settings.rack_attack['git_basic_auth'] ||= Settingslogic.new({})
Settings.rack_attack.git_basic_auth['enabled'] = true if Settings.rack_attack.git_basic_auth['enabled'].nil?
Settings.rack_attack.git_basic_auth['ip_whitelist'] ||= %w{127.0.0.1}
Settings.rack_attack.git_basic_auth['ip_whitelist'] ||= %w{118.187.12.36}
Settings.rack_attack.git_basic_auth['maxretry'] ||= 10
Settings.rack_attck.git_basic_auth['findtime'] ||= 1.minute
Settings.rack_attack.git_basic_auth['bantime'] ||= 1.hour
禁用rack_attack.rb文件
