git push 时报错：

之前处理过一个类似的报错：git push报错：“RPC failed; curl 56 GnuTLS recv error (-54): Error in the pull function.”。方案大致如下：

git config --global http.postBuffer 524288000

这次修改之后再次提交仍然报错。

最后找到一个方案提到需要修改 web 服务器的 client_max_body_size（httpd.conf）：

...
http {
...
client_max_body_size 100m;
}
...

报错之后，重载 Nginx 配置 nginx -s reload之后，再次尝试 git push，成功！
