在Linux环境下提升PHP并发能力,可以从多个方面进行优化。以下是一些常见的方法:
max_execution_time:减少脚本的最大执行时间,避免长时间运行的脚本占用资源。memory_limit:适当增加内存限制,确保脚本有足够的内存运行。opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
worker_processes auto;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
gzip on;
server {
listen 80;
server_name example.com;
location / {
root /var/www/html;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
}
$memcached = new Memcached();
$memcached->addServer('127.0.0.1', 11211);
$data = $memcached->get('key');
if (!$data) {
$data = fetchDataFromDatabase();
$memcached->set('key', $data, 3600); // 缓存1小时
}
$queue = new \PhpAmqpLib\Queue\Connection();
$channel = $queue->channel();
$channel->queue_declare('task_queue', false, true, false, false);
$msg = new \PhpAmqpLib\Message\AMQPMessage('Hello World!');
$channel->basic_publish($msg, '', 'task_queue');
通过以上方法,可以显著提升Linux环境下PHP应用的并发处理能力。根据具体应用场景和需求,选择合适的优化策略。
