1. 修改nginx的配置文件

client_max_body_size 500M;        
client_header_timeout 3600s;
client_body_timeout 3600s;
fastcgi_connect_timeout 3600s;
fastcgi_send_timeout 3600s;
fastcgi_read_timeout 3600s;
# 其他webserver相应修改类似限制;如apache需要修改LimitRequestBody
# 修改完成重启nginx生效: service nginx reload

2. 修改php配置文件php.ini;

post_max_size = 500M;
upload_max_filesize = 500M;
memory_limit = 500M;
max_execution_time = 3600;
max_input_time = 3600;

# php中设置set_time_limit无效(safe_mode=on时php代码中修改超时无效) php.ini
safe_mode = off

# php-fpm.conf 配置优化(超时时间; 4G内存推荐如下子进程配置)
request_terminate_timeout 3600
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 30
pm.max_requests = 500
