前提：有可访问的站点
1. 先到域名对应的项目地址根目录，例如：
cd /home/yxy/discuz
2. 编写PHP文件
vim upload.php
内容如下：
<?php
$path = "upload/" .date("Y/m/d/");
if(!is_dir($path)){
exec("mkdir -p ".$path);
}
move_uploaded_file($_FILES["file"]["tmp_name"],
$path. $_FILES["file"]["name"]);
echo "http://域名/". $path . $_FILES["file"]["name"];
3. 创建存文件的目标路径
mkdir upload
4. 授权Apache
chown -R apache.apache *
chmod -R 755 *
5. 编写测试页面
vim test.html
内容如下：
<html>
<body>
<form action="./upload.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
6. 授权Apache
chown apache.apache test.html
chmod 755 test.html
7. 修改PHP配置（先备份 cp /etc/php.ini /etc/php.ini20190109bak ），修改最大限制
vim /etc/php.ini
修改内容：
post_max_size = 100M
upload_max_filesize = 100M
max_execution_time = 30
8. 重启PHP
service php-fpm restart
9. 修改NGINX配置（先备份 cp nginx.conf nginx.conf20190109bak），修改最大限制
cd /etc/nginx/
vim nginx.conf
参考如下：
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
client_max_body_size 100m;
fastcgi_buffers 8 128k;
fastcgi_read_timeout 300;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
server_names_hash_bucket_size 128;
client_body_buffer_size 100m;
client_header_buffer_size 100m;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
}
10. 查看配置文件是否正确，并重启
nginx -t
nginx -s reload
11. 完毕！打开测试地址（站点域名/test.html）即可。
12. 开通接口上传
修改upload.php
如下：
<?php
$path = "upload/" .date("Y/m/d/");
if(!is_dir($path)){
exec("mkdir -p ".$path);
}
move_uploaded_file($_FILES["file"]["tmp_name"],
$path. $_FILES["file"]["name"]);
$url = "http://域名/". $path . $_FILES["file"]["name"];
$return = array('file'=>$url);
exit(json_encode($return));
postman使用效果：
