Gitlab 訪問報 403 Forbidden 錯誤

處理方法：

1、I just backed up redis (by copying /var/opt/gitlab/redis/dump.rdb).
2、I deleted all keys inside:
3、a) Login to redis by /opt/gitlab/embedded/bin/redis-cli -s /var/opt/gitlab/redis/redis.socket
     b) FLUSHALL

Retry - dont worry - first of all I found a rake::attack key inside. But after another retry it worked.
