在 CentOS 6 上部署 Zabbix 监控系统

环境

• CentOS 6.x
• Nginx
• MySQL
• PHP

部署主机

安装 Zabbix-Agent

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm

or

rpm -Uvh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm

yum clean all
yum install -y zabbix-agent

被动模式

vi /etc/zabbix/zabbix_agentd.conf

Server=1.2.3.4
ListenPort=10050
ListenIP=0.0.0.0

被动模式记得放行 10050 端口

/sbin/iptables -I INPUT -p tcp --dport 10050 -j ACCEPT
/sbin/iptables -I INPUT -p udp --dport 10050 -j ACCEPT

主动模式

Agent 主动模式不监听 10050 端口 nano /etc/zabbix/zabbix_agentd.conf

grep '^StartAgents=\|^ServerActive=\|^Hostname=' /etc/zabbix/zabbix_agentd.conf

StartAgents=0
ServerActive=zabbix-server.domain:10051
Hostname=zabbix-agent.domain

systemctl restart zabbix-agent
systemctl enable zabbix-agent
systemctl status zabbix-agent

部署服务器

安装 Server 与 Web 前端

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
rpm -Uvh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm

或 vi /etc/yum.repos.d/zabbix.repo

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/6/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

yum install -y zabbix-server-mysql zabbix-web-mysql

导入数据库模板

mysql -uroot -p
<Enter Password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by '<password>';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit;

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

修改 Zabbix 配置

vi /etc/zabbix/zabbix_server.conf

ListenPort=10051
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=<password>
DBSocket=/var/lib/mysql/mysql.sock

启动 Zabbix Server service zabbix-server start

Starting Zabbix server: [ OK ]

chkconfig zabbix-server on

修改前端目录权限

修改前端目录与 maintenance.inc.php 所在目录的权限

chown -R www-data:www-data /etc/zabbix
chown -R www-data:www-data /usr/share/zabbix

Nginx 配置

修改 php_fastcgi.conf 配置，增加前端相关目录的权限：

/etc/zabbix/web/
/usr/share/zabbix/

vi /etc/nginx/others/php_fastcgi.conf

将

fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/";

修改为

fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/:/usr/share/zabbix/:/etc/zabbix/web/";

nginx -s reload

PHP 配置

安装 Zabbix 依赖的扩展并设置相关参数

service php-fpm stop
yum install -y php-bcmath php-xmlwriter php-xmlreader

vi /etc/php.ini

memory_limit = 128M
post_max_size = 16M
max_execution_time = 300
max_input_time = 300
date.timezone = Asia/Shanghai

service php-fpm start
chown -R www-data /dev/shm
chown -R www-data /var/lib/php/session

Web 前端默认登陆用户名：Admin，密码：zabbix 。

邮件报警设置

　　Zabbix Server 自带邮件报警功能需要 curl 7.20 及更新的版本支持，同时编译时需要 -with-libcurl 参数。CentOS 6 自带的 curl 为 7.19 版本，另外 Zabbix Server 也是安装的二进制文件。避免升级 curl 与重新编译安装 Zabbix Server，还是使用 Python 脚本来实现推送邮件报警功能。

创建脚本

vi /usr/lib/zabbix/alertscripts/mail.py

#!/usr/bin/python
# coding:utf-8

import smtplib
from email.mime.text import MIMEText
import sys

mail_user = 'xxxxxxxx@gmail.com'
mail_pass = 'xxxxxxxx'

def send_mail(to_list,subject,content):
    me = "Zabbix Alert"+"<"+mail_user+">"
    msg = MIMEText(content,_charset="utf-8")
    msg['Subject'] = subject
    msg['From'] = me
    msg['to'] = to_list
    try:
        s = smtplib.SMTP_SSL("smtp.gmail.com", 465)
        s.login(mail_user,mail_pass)
        s.sendmail(me,to_list,msg.as_string())
        s.close()
        return True
    except Exception,e:
        print str(e)
        return False

if __name__ == "__main__":
    send_mail(sys.argv[1], sys.argv[2], sys.argv[3])

chmod +x /usr/lib/zabbix/alertscripts/mail.py

测试一下

/usr/lib/zabbix/alertscripts/mail.py user@gmail.com "Alert Mail Title" "Alert Mail Content"

添加报警媒介

Zabbix > 管理 > 报警媒介类型 > 创建媒体类型

名称：邮件报警
类型：脚本
脚本名称：mail.py
添加脚本参数:
{ALERT.SENDTO}
{ALERT.SUBJECT}
{ALERT.MESSAGE}

点击“更新保存”即可。

Debian 部署 5.0 TLS

Download and install Zabbix

1. Install Zabbix repository

wget https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-2+debian11_all.deb
dpkg -i zabbix-release_5.0-2+debian11_all.deb

1. Install Zabbix server, frontend

apt update
apt install zabbix-server-mysql zabbix-frontend-php

1. Create initial database

mysql -uroot -p
<password>

mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by '1Qaz2Wsx!zabbix';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;

On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
or
zcat /usr/share/zabbix-server-mysql/schema.sql.gz | mysql -uzabbix -p zabbix

Disable log_bin_trust_function_creators option after importing database schema.

mysql -uroot -p
<password>

mysql> set global log_bin_trust_function_creators = 0;
mysql> quit;

1. Configure the database for Zabbix server

# nano /etc/zabbix/zabbix_server.conf

DBPassword=1Qaz2Wsx!zabbix
DBHost=localhost
DBPort=3306
# DBSocket=/var/run/mysqld/mysqld.sock

systemctl start zabbix-server
systemctl enable zabbix-server

1. frontend

cp -R /usr/share/zabbix /var/www/benhon.net/
chown -R www-data:www-data /var/www/benhon.net

nano /etc/php/7.4/fpm/php.ini

memory_limit = 128M
post_max_size = 16M
max_execution_time = 300
max_input_time = 300

systemctl restart php7.4-fpm

nano /etc/nginx/others/php_fastcgi.conf

fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/";
>
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/:/usr/share/zabbix/:/etc/zabbix/web/";

nano /etc/nginx/conf.d/benhon.net.conf

    location /zabbix {
        auth_basic "Authorized";
        auth_basic_user_file /etc/nginx/htpasswd.conf;
    }

nano /etc/nginx/htpasswd.conf

benhon:$apr1$t4iap2fb$N0rnU6C98bgsaCDwWjxca0

nginx -t && nginx -s reload

locale -a

nano /etc/locale.gen
zh_CN.UTF-8 UTF-8

locale-gen

systemctl restart zabbix-server

reboot
