本文介绍了解决Zabbix在Ubuntu14.0.4环境下因MySQL连接数过多导致服务无法正常启动的问题。通过调整MySQL的最大连接数设置，成功解决了Zabbix的服务启动问题。

在Ubuntu 14.0.4环境下部署Zabbix时，Zabbix服务启动不了：一启动就自动关闭。

排查Zabbix的日志文件，发现有大量的MySQL连接错误：

[Z3001]connection to database 'zabbix' failed: [1040] Too many connections

问题原因：Zabbix连接MySQL的请求比较多，而MySQL默认安装时，最大连接数默认值为100，解决该问题的办法就是把MySQL的最大连接数修改大一点，我改到1000.

然后重启MySQL服务、Zabbix服务，问题解决。

在讲安装过程之前需要先把zabbix的工作流程简单的讲一遍：zabbix是个开源监控软件，通过web才能更直观的监控我们想要监控的主机，同时，zabbix从被监控主机获取到的信息需要存放在数据库中，因此zabbix+nginx/apache+php+mysql是常用的组合方式。nginx/apache提供web服务器，zabbix的web监控是由php写的，因此需要php环境，最后mysql提供存...
