zabbix 3.2安装(zabbix和mysql数据库分离)
63 yum install http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm 64 ls 65 cat zabbix.repo 66 yum -y install iksemel libssh2 zabbix-server-mysql zabbi
Linux下常用的系统监控软件有Nagios、Cacti、Zabbix、Monit等，这些开源的软件，可以帮助我们更好的管理机器，在第一时间内发现，并警告系统维护人员。
今天开始研究下Zabbix，使用Zabbix的目的，是为了能够更好的监控mysql数据库服务器，并且能够生成图形报表，虽然Nagios也能够生成图形报表，但没有Zabbix这么强大。
首先，我们先来介绍下Zabblx：
一.Zabbix简介
zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。
zabbix由zabbix server与可选组件zabbix agent两部门组成。
zabbix server可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视。
zabbix agent需要安装在被监视的目标服务器上，它主要完成对硬件信息或与操作系统有关的内存，CPU等信息的收集。
zabbix的主要特点：
- 安装与配置简单，学习成本低
- 支持多语言（包括中文）
- 免费开源
- 自动发现服务器与网络设备
- 分布式监视以及WEB集中管理功能
- 可以无agent监视
- 用户安全认证和柔软的授权方式
- 通过WEB界面设置或查看监视结果
- email等通知功能
等等
Zabbix主要功能：
- CPU负荷
- 内存使用
- 磁盘使用
- 网络状况
- 端口监视
- 日志监视
官方也提供了安装资料：http://www.zabbix.com/wiki/howto/monito
安装zabbix
yum install -y zabbix zabbix-server zabbix-server-mysql zabbix-agent zabbix-send zabbix-web zabbix-get zabbix-web-mysql trousers iksemel libssh2 mysql net-snmp-devel net-snmp-libs net-snmp-perl net-snmp-utils net-snmp
hostnamectl set-hostname zabbix
添加zabbix用户和组
groupadd zabbix
useradd -g zabbix -s /sbin/nologin -M zabbix
vim /etc/selinux/config
SELINUX=disabled
setenforce 0
systemctl stop firewalld
systemctl disable firewalld
安装开发环境
yum groupinstall "Development Tools" -y
LAMP的安装
yum install -y mariadb-server mariadb mariadb-test mariadb-devel mysql-dev httpd php php-mysql gcc net-snmp-devel curl-devel perl-DBI php-gd php-mysql php-bcmath php-mbstring php-xml libxml2-devel mariadb-devel bzip2-devel
如果不使用本地的MySQL服务器 这里mariadb-server安装包可以不装
vim /etc/php.ini
;date.timezone =
改成:
date.timezone = Asia/Shanghai
在远端Mysql服务器里添加zabbix数据库
mysql -uroot -pMyPassword -h 10.1.41.45
mysql>create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)mysql> show databases;

+-----------+-----------+-------------------------------------------+
5 rows in set (0.00 sec)
mysql> quit
导入zabbix数据库
gunzip /usr/share/doc/zabbix-server-mysql-3.2.3/create.sql.gz
mysql -uzabbix -pMyPassword -h10.1.41.45 zabbix < /usr/share/doc/zabbix-server-mysql-3.2.3/create.sql
启动httpd服务器
systemctl start httpd
systemctl enable httpd
登陆到http://10.1.41.81/zabbix
mysql -uzabbix -pMyPassword -h10.1.41.45

vim /etc/zabbix/zabbix_server.conf
ListenPort=10051
DBHost=10.1.41.45 ###如果你的数据库是安装在本地的 可以保持为默认的localhost
DBName=zabbix
DBUser=zabbix
DBPassword=MyPassword
vim /etc/zabbix/zabbix_agentd.conf
Server=10.1.41.81
ListenIP=0.0.0.0
ServerActive=10.1.41.81
Hostname=zabbix
启动服务并让他们开机启动
systemctl start snmpdsystemctl enable snmpd
systemctl enable snmptrapd
systemctl start snmptrapd
systemctl enable zabbix-server
systemctl start zabbix-server
systemctl start zabbix-agent
systemctl enable zabbix-agent
这样zabbix server 就算完成了安装
改变web主页显示的zabbix server的地址（默认为localhost）
vim /etc/zabbix/web/zabbix.conf.php
正常安装完zabbix后，登录后zabbix监控报错zabbix server is not running: the information displayed may not be current，
根据日志报错排查
cat /var/log/zabbix/zabbix_server.log
zabbix进程查看
ps aux |grep zabbix
查看监听zabbix server---------zabbix agent 10050---10051端口
netstat -nplut |grep zabbix
登陆报错解决 zabbix server is running | No.
解决方法1
setsebool -P httpd_can_network_connect on selinux 允许它通过httpd服务
关闭selinux
永久关闭vi /etc/selinux/config
#SELINUX=disabled
#SELINUXTYPE=targeted
临时关闭 setenforce 0
关闭防火墙
永久关闭 chkconfig iptables off
临时生效 iptables -F
解决方法2
cd /etc/zabbix/web/
修改配置文件
vi zabbix.conf.php
修改lochlhost为 自己服务器的IP地址
修改$DB['SERVER'] = '192.168.30.6';
修改$ZBX_SERVER = '192.168.30.6';
重启服务
service httpd restart
service zabbix-agent restart
service zabbix-server restart
