🗣 Wd提问: 程序PHPNginx配置

🤖 Ai回答:
PHP与Nginx配置指南

1、基础配置

Nginx服务器块配置

server {
listen 80;
server_name example.com;
root /var/www/html;
index index.php index.html index.htm;

location / {
try_files $uri $uri/ /index.php?$query_string;
}

location ~ \.php$ {
include fastcgi_params;
fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}

2、PHP-FPM配置

PHP-FPM池配置 (/etc/php/8.1/fpm/pool.d/www.conf)

[www]
user = www-data
group = www-data
listen = /var/run/php/php8.1-fpm.sock
listen.owner = www-data
listen.group = www-data
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

3、性能优化配置

Nginx优化参数

在http块中添加
client_max_body_size 100M;
client_body_timeout 60;
keepalive_timeout 65;

启用Gzip压缩
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

PHP优化参数 (php.ini)

memory_limit = 256M
max_execution_time = 300
upload_max_filesize = 100M
post_max_size = 100M
opcache.enable = 1
opcache.memory_consumption = 256
opcache.max_accelerated_files = 20000

4、安全配置

Nginx安全设置

隐藏Nginx版本号
server_tokens off;

防止点击劫持
add_header X-Frame-Options SAMEORIGIN;

防止MIME类型嗅探
add_header X-Content-Type-Options nosniff;

PHP安全设置

expose_php = Off
display_errors = Off
log_errors = On

5、常见问题解决

502 Bad Gateway错误
检查PHP-FPM服务状态：
bash
systemctl status php8.1-fpm

文件权限问题
设置正确的文件权限：
bash
chown -R www-data:www-data /var/www/html
find /var/www/html -type f -exec chmod 644 {} \;
find /var/www/html -type d -exec chmod 755 {} \;

6、重启服务
bash
重启Nginx
systemctl restart nginx

重启PHP-FPM
systemctl restart php8.1-fpm

这个配置涵盖了PHP与Nginx集成的主要方面，包括基础配置、性能优化、安全设置和常见问题解决方案。
