what is zabbix?
英語實在太爛，沒辦法繼續了，但總有一天要將其變爲第一語言
先來看看官方給出的定義，纯官方摘过来的https://www.zabbix.com/documentation/2.2/manual/introduction/about

What is Zabbix

Overview

Zabbix was created by Alexei Vladishev, and currently is actively developed and supported by Zabbix SIA.
Zabbix is an enterprise-class open source distributed monitoring solution.
Zabbix is software that monitors numerous parameters of a network and
the health and integrity of servers. Zabbix uses a flexible notification
mechanism that allows users to configure e-mail based alerts for
virtually any event. This allows a fast reaction to server problems.
Zabbix offers excellent reporting and data visualisation features based
on the stored data. This makes Zabbix ideal for capacity planning.
Zabbix supports both polling and trapping. All Zabbix reports and
statistics, as well as configuration parameters, are accessed through a
web-based frontend. A web-based frontend ensures that the status of your
network and the health of your servers can be assessed from any
location. Properly configured, Zabbix can play an important role in
monitoring IT infrastructure. This is equally true for small
organisations with a few servers and for large companies with a
multitude of servers.
Zabbix is free of cost. Zabbix is written and distributed under theGPLGeneral Public License version 2. It means that its source code is freely distributed and available for the general public.
Commercial support is available and provided by Zabbix Company.

Users of Zabbix

Many organisations of different size around the world rely on Zabbix as a primary monitoring platform.

约定：

一.服务端

1.创建用户

# groupadd zabbix
# useradd -g zabbix zabbix

2.创建数据库https://www.zabbix.com/documentation/2.2/manual/appendix/install/db_scripts

# cd /usr/local/src
# tar -xzvf zabbix-2.2.2.tar.gz
# cd zabbix-2.2.2

MySQL (we assume that user username with password password exists and has permissions to create database objects):

shell> mysql -u<username> -p<password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> quit;
shell> mysql -u<username> -p<password> zabbix < database/mysql/schema.sql
# stop here if you are creating database for Zabbix proxy
shell> mysql -u<username> -p<password> zabbix < database/mysql/images.sql
shell> mysql -u<username> -p<password> zabbix < database/mysql/data.sql

PostgreSQL (we assume that user username exists and has permissions to create database objects):

shell> psql -U <username>
psql> create database zabbix;
psql> \q
shell> cd database/postgresql
shell> psql -U <username> zabbix < schema.sql
# stop here if you are creating database for Zabbix proxy
shell> psql -U <username> zabbix < images.sql
shell> psql -U <username> zabbix < data.sql

Oracle (we assume that user zabbix with password password exists and has permissions to create database objects in service ORCL):

If you are creating database for Zabbix server you need to have images somewhere on Oracle host:

# copy directory create/images/old_images somewhere on Oracle server (e.g. /home/oracle):
shell> scp -r create/images/old_images user@host:/home/oracle
# edit file database/oracle/images.sql and set images_dir variable to
where you have copied them (e. g. "/home/oracle/old_images"):
CREATE OR REPLACE DIRECTORY image_dir AS '/home/oracle/old_images'

Now prepare the database:

shell> sqlplus zabbix/password@host/ORCL
sqlplus> @database/oracle/schema.sql
# stop here if you are creating database for Zabbix proxy
sqlplus> @database/oracle/images.sql
sqlplus> @database/oracle/data.sql

3.配置帮助信息

#./configure --help

4.服务端安装-mysql db

# ./configure --prefix=/usr/local/zabbix/ --enable-server \
--enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2

# make && make install

5.服务端安装-PostgreSQL

#./configure --enable-server --with-postgresql --with-net-snmp

6.服务端配置
编辑/usr/local/zabbix/etc/zabbix_server.conf配置以下参数

LogFile=/tmp/zabbix_server.log    #日志文件
DBName=zabbix                              #数据库名称
DBUser=zabbix                                 #数据库用户名
DBPassword=zabbix                        #数据库密码
DBPort=3306                                    #数据库端口

7.系统服务配置
经过上面配置，就可以通过$/usr/local/zabbix/sbin/zabbix_server启动服务，但这种启动方式并没有将zabbix服务加入系统服务，那就来配置吧。
服务脚本统一在源码目录misc/init.d下，这里又按系统做了区分，centos、redhat同属fedora，所以这里就要fedora的脚本做修改

cp misc/init.d/fedora/core/zabbix_server /etc/init.d/zabbix_server

编辑/etc/init.d/zabbix_server,修改以下参数
vim /etc/init.d/zabbix_server

BASEDIR=/usr/local/zabbix/         #zabbix安装目录

加入系统服务

chkconfig --add zabbix_agentd
chkconfig --level 345 zabbix_agentd on

启动zabbix服务

$service zabbix_server start

这里还有个问题，就是SElinux的安全验证，可使用setenfroce 0暂时关闭selinux临时解决下

二.服务端web配置

拷贝文件到web目录site下http://httpd.apache.org/docs/2.2/vhosts/

cp -rp /usr/local/zabbix-2.2.2/frontends/php /site/zabbix/

apache配置

<Directory "/site/zabbix">
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
</Directory>

<VirtualHost *:80>
#ServerAdmin
DocumentRoot /site/zabbix
ServerName localhost
ErrorLog logs/dummy-zabbix.com-error_log
CustomLog logs/dummy-zabbix.com-access_log common
</VirtualHost>

nginx配置

server {
listen    80;
server_name localhost;
access_log zabbix.com.access.log main;
index index.html index.php index.html;
root  /site/zabbix;

location /
{
try_files $uri $uri/ /index.php?$args;
}
location ~ ^(.+.php)(.*)$ {
fastcgi_split_path_info ^(.+.php)(.*)$;
include fastcgi.conf;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param PATH_INFO
$fastcgi_path_info;
}
}

安装前端
1.浏览器打开http://localhost/zabbix

如果前面的配置正确，会看到安装向导



2.确认先决条件是否满足

Pre-requisite	Minimum value	Description
PHP version	5.3.0
PHP memory_limit option	128MB	In php.ini: memory_limit = 128M
PHP post_max_size option	16MB	In php.ini: post_max_size = 16M
PHP upload_max_filesize option	2MB	In php.ini: upload_max_filesize = 2M
PHP max_execution_time option	300 seconds	In php.ini: max_execution_time = 300
PHP max_input_time option	300 seconds	In php.ini: max_input_time = 300
PHP session.auto_start option	must be disabled	In php.ini: session.auto_start = 0.
Database support	One of: IBM DB2, MySQL, Oracle, PostgreSQL, SQLite	One of the following modules must be installed: ibm_db2, mysql, oci8, pgsql, sqlite3
bcmath		php-bcmath
mbstring		php-mbstring
sockets		php-net-socket. Required for user script support.
gd	2.0 or higher	php-gd. PHP GD extension must support PNG images (--with-png-dir), JPEG (--with-jpeg-dir) images and FreeType 2 (--with-freetype-dir).
libxml	2.6.15	php-xml or php5-dom
xmlwriter		php-xmlwriter
xmlreader		php-xmlreader
ctype		php-ctype
session		php-session
gettext		php-gettext Starting with Zabbix 2.2.1, the PHP gettext extension is no longer a mandatory requirement for installing Zabbix. If gettext is not installed, the frontend will work as usual, however, the translations will not be available.

3.配置链接数据库信息，前提zabbix数据库必须已创建



4.主机信息配置




5.检查配置信息是否正确




6.生成配置文件，这里可能会出权限问题，可将配置文件下载后上传到服务器，或修改目录权限




7.登录
默认用户为admin，密码为zabbix




8.中文支持及字体更改
zabbix本身已集成中文，但需要手动开启后才会出现在语言设置中
编辑/site/zabbix/include/locales.inc.php文件，找到zh_CN，将后面的falsh改为true，就可在页面的语言设置中找到中文选项了



支持中文后，在图表数据中可能会出现乱码情况，与字体库有关，将windows下的C:\Windows\Fonts\simkai.ttf(楷体)上传到服务器 zabbix 网站目录 fonts 目录下

修改web目录/site/zabbix/include/defines.inc.php文件，做如下变更

sed -i 's/DejaVuSans/simkai/g' ./include/defines.inc.php

43行
define('ZBX_GRAPH_FONT_NAME',        'DejaVuSans'); // font file name    修改前
define('ZBX_GRAPH_FONT_NAME',        'simkai'); // font file name       修改后
90行
define('ZBX_FONT_NAME', 'DejaVuSans');                                                修改前
define('ZBX_FONT_NAME', 'simkai');                                                         修改后

三.客户端

1.客户端安装

# groupadd zabbix
# useradd -g zabbix zabbix

#./configure --enable-agent --prefix=/usr/local/zabbix/
make && make install

2.客户端配置
编辑/usr/local/zabbix/etc/zabbix_agentd.conf配置以下参数

LogFile=/tmp/zabbix_agentd.log        #日志配置
Server=127.0.0.1                                   #zabbix服务端地址，允许服务端主动来取数据
ServerActive=127.0.0.1                        #zabbix服务端地址，主动向服务端提交数据
Hostname=Zabbix server                    #客户端名称，这个名称后面在服务端添加监控主机时要用到

3.加入系统自启动服务

cp misc/init.d/fedora/core/zabbix_server /etc/init.d/zabbix_agentd

编辑/etc/init.d/zabbix_agentd,修改以下参数
vim /etc/init.d/zabbix_agentd

BASEDIR=/usr/local/zabbix/         #zabbix安装目录

加入系统服务

chkconfig --add zabbix_agentd
chkconfig --level 345 zabbix_agentd on

启动客户端
service zabbix_agentd start

如何创建监控主机，待研究明白了在来补
