About 1.1 zabbix

zabbix is based on providing a distributed system monitoring and network monitoring capabilities WEB interface, enterprise-class open source solutions.
zabbix can monitor various network parameters to ensure safe operation of the server system; and to provide a flexible notification mechanism to allow system administrators to quickly locate / solve problems.
zabbix consists of two parts, zabbix server and optional components zabbix agent.
zabbix server can provide monitoring, data collection and other functions on the remote server / network status through SNMP, zabbix agent, ping, port monitoring and other methods, it can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X and other platforms.

Said bluntly, is zabbix we are all familiar, is now more popular with a distributed control system, of course, people are now Open-Falcon (millet monitoring) is now used more and more.

1.2 zabbix components

zabbix consists of the following component parts:

Zabbix Server: agent responsible for receiving information sent by the core component of the report, all configuration, statistical and operational data will be held by their organization.
Database Storage: dedicated to storing all the configuration information, and data collected by zabbix.
Web interface: zabbix the GUI interface, usually on the same host Server running.
Proxy: optional components commonly used in the distributed monitoring environment, the proxy Server collects monitoring data terminal section monitored and sent to the Server unified end (to achieve non-essential components of a distributed monitoring dedicated components are excessive or across the room monitoring server can use this components.)

Agent: deployed on the monitored host, is responsible for collecting local data and sent to the Proxy Server side or end.
Note: zabbix node is zabbix one kind of server. But now it has basically abandoned.

1.3 zabbix monitoring environment related terms

Host (host): to monitor network devices, designated by the IP or DNS name

Host group (host group): the host logical container may contain a host and template, but within the same organization and the master template can not be linked to each other; host group commonly used in assigning monitoring privileges to users or user groups

Monitoring item (item): a specific data related to monitoring indicators; these data from the monitored object; zabbix item is at the heart of data collection, relative to a monitored object, each item by "key" to identify
the trigger ( trigger): an expression within a particular data item is received for assessing whether the monitored object is within a reasonable range, i.e. the threshold value; when the received data is larger than the threshold value, a trigger condition from "OK" to " Problem ", when the data is once again restored to a reasonable range, but also into" OK "
event (event): trigger a matter of concern, such as triggers state transition, the new agent or automatic re-register on-line agent and other
actions (action ): means for processing a specific event defined in advance, such as sending a notification, the operation performed when
an alarm upgrade (Escalation): transmitting an alarm or execute remote commands custom program, such as an alert sent once every five minutes, a total of five transmission other
media (media): means for sending the notification or channel, such as Email, Jabber, or the like SMS
notification (notification : The information about a selected media event sent to the user
remote command (remote command): predefined commands can be executed automatically at a certain time under certain conditions in the monitored host
template (template): for quick definition is a collection of pre-entry monitoring host, usually containing the item, trigger, graph, screen, application , and low-level discovery rule; templates can be linked directly to a host
application (application): a group item of the collection
web scene (web scennario ): a web site for detecting the availability of a plurality of HTTP requests or

Front end (frontend): Zabbix the web interface

Two, zabbix installation

2.1 server installation (Centos6)

(1). Yum install the necessary environment

# yum install httpd php http-devel php-devel php-pear php-xmlrpc php-bcmath mysql-connector-odbc mysql-devel libdbi-dbd-mysql httpd-manual mod_ssl mod_perl mod_auth_mysql php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-bcmath mysql-connector-odbc mysql-devel libdbi-dbd-mysql net-snmp-devel curl-devel unixODBC-devel OpenIPMI-devel java-devel -y

# yum install -y libssh2-devel

# yum install -y openldap openldap-devel

Note (There are two separate lists yum come, because our translation parameters are more, not yum two lines of the above words will complain):

Bash

如果报错：configure: error: SSH2 library not found
就yum install -y libssh2-devel
如果报错：configure: error: Invalid LDAP directory - unable to find ldap.h
就：yum install openldap openldap-devel

(2). 配置php环境
sed -i “s/;date.timezone =/date.timezone = Asia\/Shanghai/g” /etc/php.ini

# MySQL -uzabbix -pzabbix ZABBIX </root/zabbix-2.4.8/database/mysql/images.sql
# MySQL -pzabbix ZABBIX -uzabbix </root/zabbix-2.4.8/database/mysql/data.sql
(. 7). startup script and copy configuration

# cp /root/zabbix-2.4.8/misc/init.d/fedora/core/zabbix_* /etc/init.d/
# sed -i “s#BASEDIR=/usr/local#BASEDIR=/usr/local/zabbix#” /etc/init.d/zabbix_server

# sed -i “s#BASEDIR=/usr/local#BASEDIR=/usr/local/zabbix#” /etc/init.d/zabbix_agentd

(8) .zabbix master profile modification

# Cat /etc/zabbix/zabbix_server.conf|grep -v "^ #" | grep -v "^ $" # simple configuration a bit, mainly to configure account and password to connect database

Bash

LogFile=/var/zabbix/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
ListenIP=127.0.0.1

Mkdir # / var / zabbix
# chown zabbix: zabbix / var / zabbix /
(9) a copy of the page file to the web site directory.

Cp -r /root/zabbix-2.4.8/frontends/php # / var / the WWW / HTML / zabbix
# chown the Apache: the Apache / var / the WWW / HTML / conf # zabbix under this directory, the program to be created / a php, of course, not authorized, then wait until the installation department where, under php files can also be downloaded.

(10). Zabbix configured via a web page

http://192.168.1.102/zabbix # access url format is IP / zabbix format

# Then follow the prompts to the next step, what to fill it fill what, this web guide installation interface is relatively simple.

# After successful installation, visit the above url again, is the login page, the default account is admin, password is zabbix.

2.2 server installation (Centos7)

Now more and more online with Centos7 system, zabbix version also becomes the 3 series, although I was online zabbix 2.4 series, but with a new version of a trend, are back with a new version of the operating Example.

(1). Yum install the necessary environment

# Yum install httpd php php-devel php-pear php-xmlrpc php-bcmath mariadb mariadb-server mariadb-devel httpd-manual mod_ssl php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-bcmath libdbi -dbd-mysql net-snmp-devel curl-devel unixODBC-devel OpenIPMI-devel java-devel -y # the main difference here is the mysql changed mariadb.

# yum install -y libssh2-devel

# yum install -y openldap openldap-devel

(3) Install the server zabbix

# wget https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.2.6/zabbix-3.2.6.tar.gz

# make install
# ln -s /usr/local/zabbix-3.2.6 /usr/local/zabbix

Note: To support the monitoring zabbix vmware at compile time, there must configure -with-libxml2 -with-libcurl, the former calling for parsing XML SOAP interface has returned, which used to call vcenter the SOAP interface.

# /Etc/init.d/zabbix_server start # start zabbix_server Service

agent # /etc/init.d/zabbix_agentd start # also start up the machine, in order to see the effect in FIG.

Pictures .png

# Home from it all has become Chinese.

# But there is a problem see below:

Pictures .png

# Can be seen from the figure, all the characters are white frame is not shown.

Solution:

Windos into the local directory: C: \ Windows \ Fonts (with Microsoft elegant black msyh.ttf for example).

The windows side msyh.ttf upload files to the server's / var / www / html / zabbix / fonts directory.

#ls -l /var/www/html/zabbix/fonts/msyh.ttf # look really exist

Bash

-rw-r--r-- 1 root root 21767952 6月  11 2009 /var/www/html/zabbix/fonts/msyh.ttf

# vim /var/www/html/zabbix/include/defines.inc.php +45

define(‘ZBX_GRAPH_FONT_NAME’, ‘DejaVuSans’); 替换为：define(‘ZBX_GRAPH_FONT_NAME’, ‘msyh’); #就是DejaVuSans替换为msyh
