PHP mysql连接帮助（ubuntu LAMP服务器）
[英]PHP mysql connections help ( ubuntu LAMP server)
问题描述
So last night I had a cpu spike for 100% for 30 minutes which made the server not very usable :-( 
因此，昨晚我在30分钟内将CPU峰值提高了100％，这使得服务器不太可用:-(
The server doesn't seem to be the quickest even today (its running on Amazon cloud!). 即使在今天，该服务器似乎也不是最快的（它在Amazon云上运行！）。
The application is a chat application which only has about registered 5 users who's client polls a php script every every 5 seconds for new information ( each request hits mysql). 该应用程序是一个聊天应用程序，只有大约5个注册用户，其客户端每5秒钟轮询一次php脚本以获取新信息（每个请求都命中mysql）。
Running some commands I found on the net it returned that I have 200 thousand connections - is this active or since the server was up? 运行我在网上发现的一些命令后，它返回了20万个连接-这是活动的还是服务器已启动？
Can anyon offer any advice if there is anything out of the ordinary in the below. 如果以下任何异常之处，任何人都可以提供任何建议。
(Note these stats are from today where there were only 2 users logged in) （请注意，这些统计数据是从今天开始只有2位用户登录的）

120 thosand connections since your mysql running up. 自从您的mysql运行以来，已有120个thosand连接。 About 100% of cpu. 大约100％的CPU。 Check apache logs in /var/logs/apacheX looking for excessive error messages. 检查/ var / logs / apacheX中的apache日志，查找过多的错误消息。 It can be the server slow. 可能是服务器运行缓慢。
