Zabbix-server post-Installation fault handling and zabbix-agent configuration add process

Fault Handling

In the first case, if the Web interface is prompted with the correct configuration of other parameters (Iptables, SELinux, etc.), such as:

650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M00/78/0C/wKioL1Z07gSgrUvsAAC6P2ObuUM654.png "title=" capture. PNG1. PNG "alt=" Wkiol1z07gsgruvsaac6p2obuum654.png "/>

If you are unable to connect, go to the system where Zabbix-server is located and test with Telnet.

[[Email protected] conf]# telnet localhost 10051Trying:: 1...telnet:connect to Address:: 1:connection refusedtrying 127. 0.0.1...telnet:connect to address 127.0.0.1:connection refusedtrying 192.168.2.101 ... [Email protected] conf]# telnet 127.0.0.1 10051Trying 127.0.0.1 ...

It is not possible to see the 10051 port on localhost, at which point you can make the following adjustments.

[Email protected] conf]#/usr/share/zabbix/conf/zabbix.conf.php #官方RPM安装的PHP代码文件位置 $ZBX _server = ' loc                     Alhost '; #修改此参数

Change localhost to 127.0.0.1.

Second case: The database Mysql.sock file could not be found for an issue

Make sure the/var/lib/mysql/mysql.sock exists and if it does not, modify the Dbsocket configuration in the/etc/zabbix/zabbix_server.conf.

Dbsocket=/var/lib/mysql/mysql.sock

Note: After modifying the path to Mysql.sock actually exists, restart the service.

Third case: Database cannot connect prompt

There are three workarounds: check whether the database service is healthy, whether the firewall is allowed, or if the permissions are accessible.

Zabbix-agent the configuration Add process

1. Installing Zabbix-agent
   

   In the previous article, I introduced Zabbix can adopt the Agent/server architecture, the client's collection method is divided into agent, SNMP, etc., here first to learn to use Agent to monitor the server, I will be on other monitoring methods (SNMP, JMX, IPMI) is described in detail below, which describes how zabbix-agent is installed manually.

   The client is still installed in rpm (install Zabbix's official Yum source).

[[email protected] conf]# rpm-ivh[[email protected] conf]# yum–y install Zabbix zabbix-agent

2. Configuration of the firewall

The setup statements for the firewall are as follows.

#vim/etc/sysconfig/iptables-a input–m State--state new–m tcp–p TCP--dport 10050-j accept-a output–m State-- State new–m tcp–p TCP--dport 10051-j ACCEPT #service iptables restart

3. Configure zabbix_agent.conf

The default configuration parameters are as follows.

#vim/etc/zabbix/zabbix-agent.confserver=x.x.x.x Zabbix-server's iphostname=xxx.xxx.xxx.xxx monitored host address

An agent can send data to multiple servers at the same time, with multiple IPs separated by commas.

#service zabbix-agent restartchkconfig zabbix-agent onchkconfig iptables on

So far, the work on the Zabbix-agent host has been configured, and the next step is to add the monitored host to the Zabbix-server Web management interface.
