在LNMP(Linux, Nginx, MySQL, PHP)环境中实现PHP会话持久化,可以通过以下几种方法:
安装Memcached和PHP Memcached扩展:
sudo apt-get install memcached
sudo apt-get install php-memcached
配置Nginx以支持Memcached:
编辑Nginx配置文件(例如 /etc/nginx/nginx.conf
或 /etc/nginx/sites-available/default
),添加以下内容:
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_param PHP_VALUE[session.save_handler] = memcached;
fastcgi_param PHP_VALUE[session.save_path] = "/var/run/memcached/memcached.sock";
}
启动Memcached服务:
sudo systemctl start memcached
sudo systemctl enable memcached
安装Redis和PHP Redis扩展:
sudo apt-get install redis-server
sudo apt-get install php-redis
配置Nginx以支持Redis:
编辑Nginx配置文件(例如 /etc/nginx/nginx.conf
或 /etc/nginx/sites-available/default
),添加以下内容:
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_param PHP_VALUE[session.save_handler] = redis;
fastcgi_param PHP_VALUE[session.save_path] = "tcp://127.0.0.1:6379";
}
启动Redis服务:
sudo systemctl start redis-server
sudo systemctl enable redis-server
编辑Nginx配置文件(例如 /etc/nginx/nginx.conf
或 /etc/nginx/sites-available/default
),添加以下内容:
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_param PHP_VALUE[session.save_handler] = files;
fastcgi_param PHP_VALUE[session.save_path] = "/var/lib/php/sessions";
}
设置会话存储目录权限:
sudo mkdir -p /var/lib/php/sessions
sudo chown www-data:www-data /var/lib/php/sessions
sudo chmod 770 /var/lib/php/sessions
创建会话表(例如在MySQL中):
CREATE TABLE `sessions` (
`id` char(32) NOT NULL DEFAULT '',
`data` blob NOT NULL,
`expire` int(11) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
配置PHP以使用数据库存储会话:
编辑 php.ini
文件,添加以下内容:
session.save_handler = db
session.save_path = "mysql:host=localhost;dbname=your_database;charset=utf8"
session.gc_probability = 1
session.gc_divisor = 100
session.gc_maxlifetime = 1440
启动MySQL服务(如果尚未启动):
sudo systemctl start mysql
sudo systemctl enable mysql
通过以上方法,您可以在LNMP环境中实现PHP会话持久化。选择哪种方法取决于您的具体需求和环境。
