1.yum -y install zabbix-agent;
2.安装完成后配置文件一般在 /etc/zabbix/zabbix_agentd.conf，打开把里面内容全部清空然后加入
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log #错误日志
LogFileSize=0
ListenPort=10050 #启动监听端口
StartAgents=3 #被动模式下选择，主动模式则为0
ListenIP=0.0.0.0 #监听所有IP
Server=10.27.146.250 #被动模式下必填，将zabbix-server端的ip填入
#ServerActive=10.27.146.250 #主动模式下填写
Hostname=Api1Bearead #本机的hostname，此值必须与zabbix的网页上创建的主机名一致即可
Include=/etc/zabbix/zabbix_agentd.d/3.service zabbix-agent restart #启动客户端
4.在zabbix的网页端创建一个新的项目
请确保这里的主机名和配置的主机名一致，这里的IP填写的是安装客户端服务器的IP地址

解决办法：
出现该错误的原因是一般是zabbix_agentd.conf里面的Hostname和前端zabbix web里面的配置不一样所造成的，即在zabbix web页面Monitoring->Configuration->Hosts 页面的Host Name和zabbix_agentd.conf里面的Hostname要一样。
再看后台日志信息，正常如下：
[root@db_m1_slave_1 zabbix-3.0.2]# tail -f/var/log/zabbix/zabbix_agentd.log

后台zabbix服务器日志： [root@hch_test_121_12 ~]# /usr/local/zabbix/bin/zabbix_get -s 192.168.1..71 -p10050 -k mysql.status[Com_update] Warning: Using a password on the command line interface can be insecure. 92315 [root@hch_test_121_12 ~]#
解决办法是，在zabbix客户端，添加用户名密码配置，这样避免shell密码外泄也不会报错，（这里报这种错误是因为返回的结果集中有字符串提醒信息，而后台zabbix的item的是decimal所以存储不进去报错）： vim /usr/local/mysql/my.cnf [mysqladmin] user=zabbix password=ys_ipowerlong0418
然后重启zabbix_agent 然后在后台zabbix测试，没有报多余的信息： [root@hch_test_121_12 ~]# /usr/local/zabbix/bin/zabbix_get -s 192.168.1..71 -p10050 -k mysql.status[Com_insert] 58272 [root@hch_test_121_12 ~]#
之后再看zabbix_server后台日志，正常了不会报错了，如下所示： 12855:20160422:233520.636 item "db_master_2:mysql.status[Bytes_received]" became supported 12857:20160422:233521.636 item "db_master_2:mysql.status[Bytes_sent]" became supported 12854:20160422:233522.637 item "db_master_2:mysql.status[Com_begin]" became supported 12856:20160422:233523.638 item "db_master_2:mysql.status[Com_commit]" became supported 12857:20160422:233524.641 item "db_master_2:mysql.status[Com_delete]" became supported 12855:20160422:233525.642 item "db_master_2:mysql.status[Com_insert]" became supported 12856:20160422:233526.642 item "db_master_2:mysql.status[Com_rollback]" became supported 12854:20160422:233527.643 item "db_master_2:mysql.status[Com_select]" became supported 12855:20160422:233528.645 item "db_master_2:mysql.status[Com_update]" became supported 12857:20160422:233529.646 item "db_master_2:mysql.status[Questions]" became supported 12856:20160422:233530.646 item "db_master_2:mysql.status[Slow_queries]" became supported

配置文件坏了，copy一个备份的过来，改下，重启agent。
