LAMP环境下zabbix 4.0安装配置_zabbix源码安装lamp4.0

Zabbix简介

Zabbix是一个企业级的开源分布式监控解决方案，由一个国外的团队持续维护更新，软件可以自由下载使用，运作团队靠提供收费的技术支持赢利。

官方网站：http://www.zabbix.com

Zabbix 1.8官方文档：http://www.zabbix.com/documentation/1.8/start

Zabbix通过C/S模式采集数据，通过B/S模式在web端展示和配置。

被监控端：主机通过安装agent方式采集数据，网络设备通过SNMP方式采集数据

Server端：通过收集SNMP和agent发送的数据，写入MySQL数据库，再通过php+apache在web前端展示。

Zabbix运行条件：

Server：

Zabbix Server需运行在LAMP（Linux+Apache+Mysql+PHP）环境下，对硬件要求低

Agent：

目前已有的agent基本支持市面常见的OS，包含Linux、HPUX、Solaris、Sun、windows

SNMP：

支持各类常见的网络设备

一：zabbix概述

1.1：Zabbix功能

具备常见的商业监控软件所具备的功能（主机的性能监控、网络设备性能监控、数据库性能监控、FTP等通用协议监控、多种告警方式、详细的报表图表绘制）

支持自动发现网络设备和服务器

支持分布式，能集中展示、管理分布式的监控点

扩展性强，server提供通用接口，可以自己开发完善各类监控

1.2：Zabbix 优劣势

优点：

开源，无软件成本投入

Server对设备性能要求低（实际测试环境：虚拟机Redhat EL AS5，2GCPU
1G内存，监控5台设备，CPU使用率基本保持在10%以下，内存剩余400M以上）

支持设备多

支持分布式集中管理

开放式接口，扩展性强

缺点：

全英文，界面不友好

无厂家支持，出现问题解决比较麻烦

需在被监控主机上安装agent

二：zabbix部署安装

操作系统：CentOS7.6

IP地址：20.0.0.45

Web环境：Nginx+MySQL+PHP

zabbix版本：Zabbix 4.0 LTS

备注：Linux下安装zabbix需要有LAMP或者LNMP运行环境

2.1：安装LNMP

环境准备

[root@zabbix ~]#  systemctl stop firewalld && systemctl disable firewalld

'临时关闭跟永久关闭防护功能'
[root@zabbix ~]# setenforce 0 && sed -i "s/SELINUX=*/SELINUX=disabled/g" /etc/selinux/config

安装nginx1.14

'安装yum源码'
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

'创建yum仓库'
[root@zabbix ~]# vim /etc/yum.repos.d/ngin.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

[root@zabbix ~]# yum clean all   '清理cache缓存'
[root@zabbix ~]# yum list

'其中baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/，把”OS”替换成”rhel”或”centos”，把”OSRELEASE”替换成”6”或”7”，用于6.x或7.x版本。
'
'开启nginx服务并设置开机启动'
[root@zabbix ~]# yum install nginx -y
[root@zabbix ~]# systemctl start nginx
[root@zabbix ~]# systemctl enable nginx

'查看nginx端口'
netstat -ntap | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      19485/nginx: master

进行访问查看

2.2：安装mysql 5.7

[root@zabbix ~]# yum install -y mariadb-server mariadb

'开启服务'
systemctl enable mariadb.service
systemctl start  mariadb.service
mysql_secure_installation                 '初始化'

'//接下来执行mysql安全配置向导'
[root@server ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 	'//初次运行直接回车'
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y	'//y。设置密码'
New password: 	'//输入密码'
Re-enter new password: 	'//重复输入一次'
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y	'//是否删除匿名用户，建议y删除'
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y	       '//是否禁止root远程登录，建议y禁止'
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] n	'//是否删除test数据库，根据实际情况'
 ... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y	         '//是否重新加载权限表，建议y'
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

max_input_time = 300	    '//378行，接受数据的等待时间'
memory_limit = 128M		    '//389行，每个脚本的占用内存限制'
post_max_size = 16M		    '//656行，post数据的最大限制'
upload_max_filesize = 2M	'//799，下载文件的大小限制'
