zabbix server 2.2.3 yum安装文档
zabbix server安装文档：1）安装zabbix server 2.2.3。
1.添加zabbix 源：
1
#rpm -ivh http://repo.zabbix.com/zabbix/2.2/rhel/5/x86_64/zabbix-release-2.2-1.el5.noarch.rpm
2.安装
1
#yum install zabbix-server-mysql.x86_64 zabbix-server.x86_64 zabbix.x86_64
2）安装mysql server。
目前这边采用的mysql是Percona Server 56.安装方式为yum。
1.添加Percoca的源：
1
#rpm -ivh http://www.percona.com/redir/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
2.安装Percona-Server-server-56：
1
#yum install Percona-Server-server-56.x86_64 -y
3.初始化mysql：
创建mysql的数据目录
1
2
#mkdir /data1/mysql_3306/
#chown mysql.mysql /data1/mysql_3306/
安装默认数据库：
1
2
#mysql_install_db --datadir=/data1/mysql_3306/data --user=mysql --log-bin=mysql_3306-bin
#mysqladmin -urootpassword 'xxxxx'
配置文件及启动脚本请看附件。请把.txt去掉即可。
4.初始化zabbix数据表：
创建zabbix数据库：
1
2
#mysql -S /data1/mysql_3306/mysql.sock
mysql> create database zabbix;
导入zabbix数据表：
1
2
3
4
#cd /usr/share/doc/zabbix-server-mysql-2.2.3/create
#mysql -S /data1/mysql_3306/mysql.sock zabbix < schema.sql
#mysql -S /data1/mysql_3306/mysql.sock zabbix < images.sql
#mysql -S /data1/mysql_3306/mysql.sock zabbix < data.sql
添加zabbix用户用于zabbix 使用：
1
mysql> GRANT ALL PRIVILEGES ON `zabbix`.* TO 'zabbix'@'localhost' IDENTIFIED BY 'xxxxxxx';
3)安装zabbix 前端。
1.安装zabbix-web,httpd,php
1
#yum install zabbix-web.noarch zabbix-web-mysql.noarch
2.配置zabbix-web
前端机需要关闭seliunx。

# ***Replication related settings
# Unique server identification number between 1 and 2^32-1. This value
# is required for both master and slave hosts. It defaults to 1 if
# "master-host" is not set, but will MySQL will not function as a master
# if it is omitted.
server-id = 1903306
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# changes in this file to the variable values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
# Make the slave read-only. Only users with the SUPER privilege and the
# replication slave thread will be able to modify data on it. You can
# use this to ensure that no applications will accidently modify data on
# the slave instead of the master
#read_only
#*** MyISAM Specific options
# Size of the Key Buffer, used to cache index blocks for MyISAM tables.
# Do not set it larger than 30% of your available memory, as some memory
# is also required by the OS to cache rows. Even if you're not using
# MyISAM tables, you should still set it to 8-64M as it will also be
# used for internal temporary disk tables.
key_buffer_size = 2G
# MyISAM uses special tree-like cache to make bulk inserts (that is,
# INSERT ... SELECT, INSERT ... VALUES (...), (...), ..., and LOAD DATA
# INFILE) faster. This variable limits the size of the cache tree in
# bytes per thread. Setting it to 0 will disable this optimisation.Do
# not set it larger than "key_buffer_size" for optimal performance.
# This buffer is allocated when a bulk insert is detected.
bulk_insert_buffer_size = 64M
# This buffer is allocated when MySQL needs to rebuild the index in
# REPAIR, OPTIMIZE, ALTER table statements as well as in LOAD DATA INFILE
# into an empty table. It is allocated per thread so be careful with
# large settings.
myisam_sort_buffer_size = 128M
# The maximum size of the temporary file MySQL is allowed to use while
# recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.
# If the file-size would be bigger than this, the index will be created
# through the key cache (which is slower).
myisam_max_sort_file_size = 10G
# If a table has more than one index, MyISAM can use more than one
# thread to repair them by sorting in parallel. This makes sense if you
# have multiple CPUs and plenty of memory.

innodb_additional_mem_pool_size = 16M
# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
# row data. The bigger you set this the less disk I/O is needed to
# access data in tables. On a dedicated database server you may set this
# parameter up to 80% of the machine physical memory size. Do not set it
# too large, though, because competition of the physical memory may
# cause paging in the operating system.Note that on 32bit systems you
# might be limited to 2-3.5G of user level memory per process, so do not
# set it too high.

# InnoDB stores data in one or more data files forming the tablespace.
# If you have a single logical drive for your data, a single

# logs. Value 0 means that the log is only written to the log file and
