gitlab可以成功clone和push，但是提交后的文件却无法查看。从页面上看的话只显示出500错误。
查了下gitlab的日志
tail -f /var/log/gitlab/gitlab-rails/production.log
显示如下异常：

查了下内存为2G，已经满足gitlab最小内存1G的要求。
[root@xxxxxx ~]# free -h total used free shared buffers cached Mem: 1.8G 1.7G 63M 43M 9.7M 140M -/+ buffers/cache: 1.6G 213M Swap: 0B 0B 0B
但是非常诡异的是swap为0，网上找了发现也有人遇到相应的问题。于是修改下swap的大小
[root@xxxx ~]# free -h total used free shared buffers cached Mem: 1.8G 1.7G 63M 43M 9.7M 140M -/+ buffers/cache: 1.6G 213M Swap: 0B 0B 0B [root@xxxx ~]# mkdir /swapfile [root@xxxx ~]# cd /swapfile [root@xxxx swapfile]# sudo dd if=/dev/zero of=swap bs=1024 count=2000000 2000000+0 records in 2000000+0 records out 2048000000 bytes (2.0 GB) copied, 39.1198 s, 52.4 MB/s [root@xxxx swapfile]# sudo mkswap -f swap Setting up swapspace version 1, size = 1999996 KiB no label, UUID=75b00bde-7aed-48f3-b373-126a2054ad26 [root@xxxx swapfile]# sudo swapon swap swapon: /swapfile/swap: insecure permissions 0644, 0600 suggested.

修改后再次查看，果断地出来了，记录于此。
