centos6.5下zabbix2.4.8安装配置
一、zabbix特性简介Zabbix可以监控网络和服务的监控状况. Zabbix利用灵活的告警机制，允许用户对事件发送基于Email的告警. 这样可以保证快速的对问题作出相应. Zabbix可以利用存储数据提供杰出的报告及图形化方式. 这一特性将帮助用户完成容量规划
二、本次实战环境
名称主机名ipzabbix serverserver134192.168.159.134zabbix agentserver135192.168.159.135 三、服务器安装步骤
3.1、安装开发软件包及zabbix安装所依赖的软件包
yum groupinstall "Development Tools"
# yum install php-common php-odbc php-pear curl curl-devel perl-DBI php-xml ntpdatephp-bcmath mysql httpd php-mysql mysql-server php php-gdntpdate
3.2、同步服务端的时间，避免时间不同导致不可用的监控数据
# ntpdate pool.ntp.org
8 Feb 18:41:20 ntpdate: step time server 85.199.214.100 offset 4.665038 sec
3.3、创建zabbix服务运行的用户和组
# groupadd -g 201 zabbix
# useradd -g zabbix -u 201 -m zabbix
3.4、启动mysql、创建zabbix数据库、设置用户密码访问
# /etc/init.d/mysqld start
# mysql -u root -p
mysql> create database zabbix character set utf8;
Query OK, 1 row affected (0.08 sec)
mysql> grant all privileges on *.* to 'zabbix'@'%' identified by 'zishang77';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
因本文使用的是mysql5.7，MySQL默认开启了validate_password插件，进行密码验证，需要很强的密码强度才能通过认证此版本对密码的要求比较严格，本文做了如下调整
查阅官方文档后发现有以下三种密码策略：
PolicyTests Performed0 or LOWLength1 or MEDIUMLength; numeric, lowercase/uppercase, and special characters2 or STRONGLength; numeric, lowercase/uppercase, and special characters; dictionary file
mysql> select @@validate_password_policy;
+----------------------------+
| @@validate_password_policy |
+----------------------------+
| MEDIUM |
+----------------------------+
1 row in set (0.00 sec)
mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name | Value|
+--------------------------------------+--------+
| validate_password_check_user_name | OFF |
| validate_password_dictionary_file | |
| validate_password_length | 8 |
| validate_password_mixed_case_count | 1 |
| validate_password_number_count | 1 |
| validate_password_policy | MEDIUM |
| validate_password_special_char_count | 1 |
+--------------------------------------+--------+
7 rows in set (0.08 sec)
mysql> set global validate_password_policy=0;#设置密码的策略为low
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_mixed_case_count=0#设置指定了密码中大小字母的长度
-> ;
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_number_count=2;#设置指定了密码中数据的长度
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_special_char_count=0;#设置密码中的特殊字符为0
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_length=6;#设置密码长度为6
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> grant all privileges on *.* to 'zabbix'@'%' identified by 'zabbix';
Query OK, 0 rows affected, 1 warning (0.06 sec)
3.5、安装zabbix，并导入zabbix包中的数据到mysql的zabbix数据库中
# tar zxvf zabbix-2.4.8.tar.gz
# cd zabbix-2.4.8
# cd zabbix-2.4.8
# mysql -uzabbix -pzabbix zabbix
