MYSQL interactive_timeout跟wait_timeout、NGINX keepalive_timeout
MYSQL interactive_timeout和wait_timeout、NGINX keepalive_timeout
MYSQL interactive_timeout和wait_timeout
交互式和非交互式连接,是否是交互模式的连接,由客户端决定的
大家一般什么情况下使用哪种连接,根据是什么?
NGINX keepalive_timeout
这个配置的第二个参数是什么意思
我现在的服务器已经配置了第一个参数 keepalive_timeout 50;
但请求的时候进程号一直在变化,并没有等50秒。。
为什么呢?
------解决方案--------------------
以下是我的理解
NGINX keepalive_timeout
要理解这个就得理解HTTP,一般一个HTTP请求结束以后连接就关闭了,但是有时候为了性能可以保持这个连接,下次请求就直接用这个连接。keepalive_timeout的时间就是两次请求的最大等待时间,如果超过keepalive_timeout的话就会作为超时处理。但是这也取决于客户端,如果客户端不支持keep-alive的,这个连接也不会保持,而会马上关闭,下次重新开连接。
MYSQL interactive_timeout和wait_timeout
一般可以理解成通过tcp/ip 3306端口访问的就是非交互式连接,用mysql命令访问的就是交互式连接。
超时时间的意思都是一样的,就是什么操作也不做的时候等待的最大时间。
