Shulou(Shulou.com)06/01 Report--

First, a brief introduction to the monitoring system

(1) cacti: strong data storage capacity and poor alarm performance

(2) nagios: the alarm performance is poor, and there is only a simple section to judge whether the data length is within a reasonable range, which is stored in memory. For example, when continuously sampled data is stored, the alarm will be given if the data is not within a reasonable range for three consecutive times.

(3) zabbix: combining the advantages of the above two tools, it can not only store data, but also alarm.

II. Zabbix characteristics

(1) data sampling: collect the data of the monitored host through snmp, ssh, telnet, agent, ipmi, jmx and other channels. You can customize the detection mechanism and the time interval

(2) Real-time drawing: display, read data drawing, support graph,map,screen, slide show (slide show)

(3) alarm: (upgrade the alarm and upload things that cannot be solved within a specified period of time)

(4) data storage: databases include mysql,pgsql, time series database, etc.

III. Program composition

(1) zabbix_server: server daemon

(2) daemon on zabbix_agented:agent

(3) zabbix_proxy: proxy server (optional, distributed only)

(4) zabbix_get: command line tool for manual test data acquisition

(5) zabbix_sender: a command-line tool that runs on the agent side and manually sends data to the server side

(6) zabbixjavagateway:java gateway

4. Zabbix deployment (monitoring side)

(1) zabbix depends on database configuration

① yum install mariadb-server

② vim / etc/my.cnf, add under [mysqld_safe]

Skip_name_resolve=oninnodb_file_per_table=on

③ systemctl start mariadb.service, ss-tnl

④ create database: CREATE DATABASE zabbix CHARSET utf8

⑤ authorizes an ordinary user to (access it remotely or locally): GRANT ALL ON zabbix.* TO zbxuser@'192.168.%.%' IDENTIFIED BY & apos;zbxpass'; I set it to be remote, and the local one is 127.0.0.1

⑥ FLUSH PRIVILEGES

⑦ exit

(2) configure server components

① installation server: yum install zabbix-server-mysql zabbix-get

② install webGUI:yum install zabbix-web zabbix-web-mysql

③ installs the Agent side (you can monitor yourself): yum install zabbix-agent zabbix-sender

④ zabbix server database initialization: (import create.sql into database)

Cd / usr/share/doc/zabbix-server-mysql-3.0.7/gzip-d creat.sql.gzmysql-h292.168.1.108-uzbxuser-p zabbix < create.sql

⑤ mysql; use zabbix; SHOW TABLES; View

(3) modify the server configuration file: / etc/zabbix/zabbix_server.conf (backup first)

① SourceIP: if there is more than one IP, enable one source IP and the IP authorized by the other party

② DBHost: database service address

③ DBname: same as the one we created

④ DBuser: same as the one we created

⑤ DBpassword: we customized

⑥ DBSocket: if database and server are on the same host, it will be changed. If not, it will be fine.

⑦ startup: systemctl start zabbix-server, note that if the centos is version 7. 0 or 7. 1, the trousers package should be updated.

(4) configure other matters

① installs php-mysql (rpm-Q php-mysql), which has been installed before

② configure zabbix-web, configure php time zone assignment: vim / etc/httpd/conf.d/zabbix.conf, php_value date.timezone Asia/Shanghai

③ starts httpd:systemctl start httpd.service

④ access: 192.168.1.108/zabbix

All the ok on the ⑤ side are ok:

⑥ went through the last few steps. All right.

5. Zabbix deployment (monitored side, based on agent)

① installation: yum install zabbix-agent zabbix-sender-y

② edit configuration file cd / etc/zabbix, cp zabbix_agentd.conf {, .bak}

③ vim zabbix_agentd.conf

Passive monitoring, agent waits for server to request data under passive checks related what active monitoring can be authorized by Server=192.168.1.108 separated by commas: the monitored end actively sends the data to the normal host name of the ServerActive=192.168.1.108Hostname= server under the server active checks related.

④ startup service: systemctl start zabbix-agent.service
