mysql 风控、事务、锁表、索引
2019-12-07 by Jinyang | No Comments | Filed in Uncategorized虽然在前端发起请求会做限制、在java中会做业务的限制，但是依然是无法保证绝对安全的，尤其是还是分布式部署的多集群，这时比较好的模式应该是用消息队列的生产者消费者模型，我没有使用 ，所以只能依赖数据库insert或update时在where子句中检查业务规则。 假如业务对数据安全要求不高，比如只是发放低值的优惠券，在秒杀场景下 可以降低事务等级来提高并发，这个作用很明显。但是要求严格的场景 如现金红包就不必须使用严格的事务控制机制。 假如没有正确的索引，mysql会直接锁表 导致内存占用高 事务处理慢，死锁回滚也可能发生。 所以务必要消除所有慢查询
手工升级openssh到8.1
2019-12-07 by Jinyang | No Comments | Filed in Uncategorized先升级openssl 然后在手工编译升级openssh 源只能到7.4 ，很奇怪，既然有大漏洞风险，为什么源内的版本不更新 ？

Nginx ip_hash 无效时的调整
2019-10-28 by Jinyang | No Comments | Filed in Uncategorized需要指定下hash的算法 比如： hash $remote_addr 主要看是否真实取到了客户的ip，因为有时前端可能有f5等设备改变了包文。
