一.Zabix简介
Zabbix是一款开源的监控软件，它能提供对网络，系统负载，web页面等服务的监控。并且支持实时从客户端收集数据。Zabbix能帮助监控系统的健康状态，发现故障。在Zabbix客户端，我们只需要安装一个小小的agent,就能收集数据，并且发送到Zabbix server上。Zabbix还支持在客户端与服务端加密传输数据，增加了安全性。
二.Zabbix安装（服务端）
1.lamp架构搭建
(1)安装apache
yum install httpd -y
systemctl start httpd.service
systemctl enable httpd.service
注：安装apache以后，需要关掉防火墙和selinux,或者是使firewall信任http,并且通过浏览器访问，看是否能看到测试页。可以通过curl http://icanhazip.com查看自己的公网ip。
(2)安装mysql或者是mariadb
yum install mariadb-server mariadb
systemctl start mariadb
mysql_secure_installation ##mysql安全初始化，会询问当前密码，直接回车即可。
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorization.
New password: password
Re-enter new password: password
Password updated successfully!
Reloading privilege tables..
... Success!systemctl enable mariadb.service（3）安装php
安装php
yum install php php-mysql -y ##php与php-mysql连接数据库
systemctl restart httpd.service安装php模块
yum install php-fpm
注：php-fpm是fastcgi进程管理器测试php是否正常工作
vi /var/www/html/info.php
<?php phpinfo(); ?> ##php测试页使防火墙信任http,https
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload在浏览器输入如下：
http://your_server_IP_address/info.php
2.安装Zabbix服务端
安装zabbix服务端
rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm安装Zabbix与数据库，Zabbix与web页面控件
yum install zabbix-server-mysql zabbix-web-mysql
yum install zabbix-agent ##监控服务端本身赋予数据库用户zabbix权限
mysql -uroot -p
create database zabbix character set utf8;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';## 新建zabbix用户并且赋予权限
flush privileges; ##刷新特权导入zabbix库原始数据，sql文件
cd /usr/share/doc/zabbix-server-mysql-3.0.4/
zcat create.sql.gz | mysql -uzabbix -p zabbix ##导入sql文件修改zabbix配置文件
zabbix连接数据库
vi /etc/zabbix/zabbix_server.conf
### Option: DBPassword
# Database password. Ignored for SQLite.
# Comment this line if no password is used.
#
# Mandatory: no
# Default:
DBPassword=your_zabbix_mysql_password ##数据库用户zabbix密码
zabbix连接php
vi /etc/httpd/conf.d/zabbix.conf
<IfModule mod_php5.c>
php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value always_populate_raw_post_data -1
php_value date.timezone Asia/Shanghai
</IfModule>
systemctl restart httpd
systemctl start zabbix-server
systemctl status zabbix-server
Output
● zabbix-server.service - Zabbix Server
Loaded: loaded (/usr/lib/systemd/system/zabbix-server.service; disabled; vendor preset: disabled)
Active: :active (running) since Fri 2016-08-05 07:16:35 UTC; 2s ago
Process: 10033 ExecStart=/usr/sbin/zabbix_server -c $CONFFILE (code=exited, status=0/SUCCESS)
...以上输出代表zabbix服务端正常
systemctl enable zabbix-server
配置zabbix web接口
web页面初始化设置，在浏览器输入http://your_zabbix_server_ip_address/zabbix/，点击下一步。
每一项都ok以后，点击下一步
输入zabbix用户密码，点击下一步
注：name是用来区分不同的zabbix server,当有一个监控集群时。对于单台zabbix服务器，该选项可以不填。
信息确认页面，如果确认无误，可以点击finish
默认的登录名为admin,登录密码为zabbix.
三.zabbix客户端
安装zabbix agent
rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
yum install zabbix-agent
配置加密方式传输数据
sh -c "openssl rand -hex 32 > /etc/zabbix/zabbix_agentd.psk" ##生成一个psk密码
cat /etc/zabbix/zabbix_agentd.psk ##会看到一连串乱码的数字定义zabbixserver
vi /etc/zabbix/zabbix_agentd.conf
### Option: Server
# List of comma delimited IP addresses (or hostnames) of Zabbix servers.
# Incoming connections will be accepted only from the hosts listed here.
# If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.
#
# Mandatory: no
# Default:
# Server=
Server=your_zabbix_server_ip_address ##定义zabbix主机
定义传输加密方式
vi/etc/zabbix/zabbix_agentd.conf
### Option: TLSConnect
# How the agent should connect to server or proxy. Used for active checks.
# Only one value can be specified:
# unencrypted - connect without encryption
# psk - connect using TLS and a pre-shared key
# cert - connect using TLS and a certificate
#
# Mandatory: yes, if TLS certificate or PSK parameters are defined (even for 'unencrypted' connection)
# Default:
TLSConnect=psk ##定义加密方式为psk定义psk验证id
/etc/zabbix/zabbix_agentd.conf
### Option: TLSPSKIdentity
# Unique, case sensitive string used to identify the pre-shared key.
#
# Mandatory: no
# Default:
TLSPSKIdentity=psk 001定义验证文件的位置
/etc/zabbix/zabbix_agentd.conf
### Option: TLSPSKFile
# Full pathname of a file containing the pre-shared key.
#
# Mandatory: no
# Default:
TLSPSKFile=/etc/zabbix/zabbix_agentd.psk启动zabbix agent
systemctl start zabbix-agent
systemctl enable zabbix-agent
systemctl status zabbix-agent看到输出如下，代表agent启动正常
Output
● zabbix-agent.service - Zabbix Agent
Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled)
Active: active (running) since Fri 2016-08-05 08:17:07 UTC; 5s ago
Process: 9507 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS)
...四.在Zabbix server 上添加新的监控主机
访问http://your_zabbix_server_ip_address/zabbix/
默认用户名为admin,密码是zabbix
Configuration——>Hosts ——>Create host
添加主机名和ip地址，接下来在template里面选择一个模板，例如linux server，最后配置加密传输的秘钥。psk 验证id 为之前设置的psk 001，psk value为agent机器上的/etc/zabbix/zabbix_agentd.psk的值。
点击add添加成功
看到所添加主机enable,并且可以看到监控的数据，代表zabbix配置成功。
总结：zabbix的功能十分丰富，几乎涵盖了当前市面上所有主流的监控手段。还值得笔者在今后不断的挖掘，并且根据公司业务量不断地调整。在撰写这篇文章时也参考了前人的一些文章，使我收益颇深。
