Many users ask me how to modify the upload size. You can search the method on Baidu, or you can modify it according to the following steps:

1. Find the php.ini file on the server, usually in PHP in the installation directory.

2. Search for post_max_size in the php.ini file. Generally, post_max_size=2M means that each POST data is 2M. Change it to the value you want,

for example

post_max_size=100M

3. Search for upload_max_filesize in the php.ini file. Generally upload_max_filesize=8M means the upload file size is 8M. Change it to the value you want,

for example

upload_max_filesize=50M

4. Search for max_execution_time in the php.ini file. Generally max_execution_time=30S means that the page execution time is 30S. Change it to the value you want,

for example

max_execution_time=300S

Generalpost_max_size > upload_max_filesize , the upload size depends on the minimum value.

max_execution_time When set to 0, the page execution time is not limited. When your bandwidth is slow, it is best to set it larger.

        #
        location ~ \.php$ {
            root           /home/www/htdocs;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /home/www/htdocs$fastcgi_script_name;
            include        fastcgi_params;
            client_max_body_size 35m;        #客户端上传文件大小设为35M
            client_body_temp_path /home/www/nginx_temp;        #设置临时目录
        }
