Installing Zabbix daemons
download and untar pkg


#wget http://7mnldi.com1.z0.glb.clouddn.com/zabbix-2.2.10.tar.gz
#tar -xf zabbix-2.2.10.tar.gz

Create user account


#groupadd zabbix
#useradd -g zabbix zabbix

Create Zabbix database
　　For Zabbix server and proxy daemons, as well as Zabbix frontend, a database is required. It is not needed to run Zabbix agent.

SQL scripts are provided for creating database schema and inserting the dataset. Zabbix proxy database needs only the
schema while Zabbix server database requires also the dataset on top of the schema.
　　For example: config mysql


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

　　Having created a Zabbix database, proceed to the following steps of compiling Zabbix.
Configure the sources
　　When configuring the sources for a Zabbix server or proxy, you must specify the database type to be used. Only one database type can be compiled with a server or proxy process at a time.
　　To see all of the supported configuration options, inside the extracted Zabbix source directory run:


#./configure --help
　　To configure the sources for a Zabbix server and agent, you may run something like:


#./configure --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2

　　note: –with-libxml2 configuration option is required for virtual machine monitoring, supported since Zabbix 2.2.0.

　　To configure the sources for a Zabbix server (with PostgreSQL etc.), you may run:


#./configure --enable-server --with-postgresql --with-net-snmp
　　To configure the sources for a Zabbix proxy (with SQLite etc.), you may run:


#./configure --prefix=/usr --enable-proxy --with-net-snmp --with-sqlite3 --with-ssh2
　　To configure the sources for a Zabbix agent, you may run:


#./configure --enable-agent

Make and install everything


#make install
　　This step should be run as a user with sufficient permissions (commonly ‘root’, or by using sudo).
　　Running make install will by default install the daemon binaries (zabbix_server, zabbix_agentd, zabbix_proxy) in /usr/local/sbin and the client binaries (zabbix_get, zabbix_sender) in /usr/local/bin.

　　To specify a different location than /usr/local, use a --prefix key in the previous step of configuring sources, for example --prefix=/home/zabbix. In this case daemon binaries will be installed under /sbin, while utilities under /bin. Man pages will be installed under /share.

Review and edit configuration files

• edit the Zabbix agent configuration file /usr/local/etc/zabbix_agentd.conf
  
  You need to configure this file for every host with zabbix_agentd installed.
  

　　You must specify the Zabbix server IP address in the file. Connections from other hosts will be denied.

• edit the Zabbix server configuration file /usr/local/etc/zabbix_server.conf
  
  You must specify the database name, user and password (if using any).
  

　　With SQLite the full path to database file must be specified; DB user and password are not required.

　　The rest of the parameters will suit you with their defaults if you have a small installation (up to ten monitored hosts). You should change the default parameters if you want to maximize the performance of Zabbix server (or proxy) though. See the performance tuning section for more details.

• if you have installed a Zabbix proxy, edit the proxy configuration file /usr/local/etc/zabbix_proxy.conf
  

　　You must specify the server IP address and proxy hostname (must be known to the server), as well as the database name, user and password (if using any)

　　With SQLite the full path to database file must be specified; DB user and password are not required.

Start up the daemons
　　Run zabbix_server on the server side.


#zabbix_server

　　Make sure that your system allows allocation of 36MB (or a bit more) of shared memory, otherwise the server may not start and you will see “Cannot allocate shared memory for .” in the server log file. This may happen on FreeBSD, Solaris 8.
See the “See also” section at the bottom of this page to find out how to configure shared memory.

　　Run zabbix_agentd on all the monitored machines.


#zabbix_agentd

　　Make sure that your system allows allocation of 2MB of shared memory, otherwise the agent may not start and you will see “Cannot allocate shared memory for collector.” in the agent log file. This may happen on Solaris 8.

　　If you have installed Zabbix proxy, run zabbix_proxy.


#zabbix_proxy

Installing Zabbix web interface
　　Copying PHP files

Zabbix frontend is written in PHP, so to run it a PHP supported webserver is needed. Installation is done by simply copying the PHP files from frontends/php to the webserver HTML documents directory.


#mkdir /var/www/html/zabbix
#cd frontends/php
# cp -a . /var/www/html/zabbix

Installing frontend
　　Step 1

In your browser, open Zabbix URL: http://<server_ip_or_name>

You should see the first screen of the frontend installation wizard.
　　Step 2

Make sure that all software prerequisites are met.
