这次有点难搞,由于第一次使用nginx和php的php-fpm,mysql也是使用第三方修改过mysql( 这是增强版的mysql,一个dba推荐给我 ),所以觉得有点难搞,首先就是去检查数据库用户是否远程登录,于是登录mysql,,发现的确是不允许远程登录到mysql,然
GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;后就授权远程登录依然执行程序时依然是拒绝,然后我就怀疑是否与php-fpm执行用户有关,于是又去看了一遍php-fpm的配置文件,没有看到有配置用户或者权限,真是蛋疼,然后又把关的日志文件都翻了一次,没有任何记录,

Concurrency control coordinates access to multiple transactions through MySQL isolation levels (read uncommitted, read committed, repeatable read, serialized). In practical applications, transactions, locks and concurrency control are used for product inventory management on shopping websites to ensure data integrity and avoid inventory problems.
