zabbix server is not running: the infomation displayed may not be current

正确的思路应该是先看log ( /tmp/zabbix_server.log) 在查看端口

Connection to database 'xxx' failed: [1045] Access denied for user 'xxx'@'localhost' (using password: NO)

解决方法

1. 检查 zabbix_server.conf 里面 密码是否启动

2. 检查 mysql用户zabbix 是否能够正常登录

3. 检查数据库是否授权
   show grants for zabbix@'localhost';

mysql> select user,host from mysql.user;
+--------+-----------+
| user   | host      |
+--------+-----------+
| root   | 127.0.0.1 |
| root   | localhost |
+--------+-----------+

创建,授权
grant all privileges on zabbix.* to 'zabbix'@'%' identified by 'zabbix';

如果还不行,则查看端口 其实这个应该放在第一位进行排查的

[root@localhost conf]# netstat -ntlp |grep zabbix
tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN      3672/zabbix_agentd
tcp        0      0 :::10050                    :::*                        LISTEN      3672/zabbix_agentd

我本机装了agent ,自己监控自己.
可以看到zabbix_server的端口10051根本就没起来!!!!
所以可能根本就不是帐号或者权限的问题

要去检查下配置文件 zabbix_server.conf

DBPassword=zabbix   #注意这个配置文件 不需要加引号的!

如果出现

ERROR 1045 (28000): Access denied for user 'xxx'@'localhost' (using password: YES)

首先照上 查看各权限,如果还不行 则

删除匿名用户.
mysql> use mysql 
mysql> delete from user where user=''; 
mysql> flush privileges;

今天监控突然启动不起来了.报错如出一辙,以为谁动了配置.赶紧上去看log

显示CacheSize不足了.所以去配置文件调整下就好了.
