快速搭建 zabbix 监控系统

快速搭建 zabbix 监控系统

一、系统环境

日志输出

1.1 zabbix版本

3.0 LTS  稳定版

rpm -i http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

4.0 LTS  正式版

rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

pre-4.0版

rpm -i http://repo.zabbix.com/zabbix/3.5/rhel/7/x86_64/zabbix-release-3.5-1.el7.noarch.rpm

查看系统版本

cat /etc/redhat-release

关闭防火墙及selinux

systemctl stop firewalld

查看防火墙状态并关闭开机自启

systemctl status firewalldsystemctl disable firewalld

查看开机是否启动防火墙服务

systemctl is-enabled firewalld

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

此项生效需重启机器

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

二、数据库安装及配置

1.配置yum源

# 先安装wget

yum install wget -y

2.下载mysql源安装包

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

3.安装数据库

yum localinstall mysql57-community-release-el7-8.noarch.rpm -y

4.检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*-community.*"yum install mysql-community-server -y

启动MySQL服务

systemctl start mysqld

查看MySQL的启动状态

systemctl status mysqld

5.设置开机启动

systemctl enable mysqldsystemctl daemon-reload

三.zabbix server端的配置

1.安装MySQL数据库与知识库

rpm -i http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

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

3.编辑  /etc/httpd/conf.d/zabbix

vi /etc/httpd/conf.d/zabbix.conf#注释去掉时间改为上海Asia/Shanghai

4.重启httpd

systemctl restart httpd

5.修改数据库修改root默认密码

mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。

查看默认密码

grep 'temporary password' /var/log/mysqld.log

其中 jIDqgfoE-2KZ 就是我的默认密码

#登陆数据库 mysql -uroot -p修改默认密码mysql> SET PASSWORD = PASSWORD('Lenovo@123');#Lenvoo@123是你的新密码

***************************************************************

如何解决ERROR 1819 (HY000): Your password does not satisfy the current policy requirements呢？ 必须修改两个全局参数：首先，修改validate_password_policy参数的值set global validate_password_policy=0; 再修改密码的长度set global validate_password_length=1;再次执行修改密码就可以了ALTER USER 'root'@'localhost' IDENTIFIED BY 'Lenovo@123';***********允许root远程登陆**********GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Lenovo@123' WITH GRANT OPTION;

6.创建MySQL 数据库和用户

mysql –uroot –pmysql> create database zabbix character set utf8;Query OK, 1 row affected (0.00 sec)mysql> grant all privileges on zabbix.* to 'zabbix'@'localhost' identified by 'zabbix';Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

切换到zabbix数据库

use zabbix

7.导入模板数据

source /usr/share/doc/zabbix-server-mysql-3.4.7/create/schema.sqlsource /usr/share/doc/zabbix-server-mysql-3.4.7/create/images.sqlsource /usr/share/doc/zabbix-server-mysql-3.4.7/create/data.sql#或者zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

8.配置Zabbix server

cp /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf.bak

编辑文件/etc/zabbix/zabbix_server.conf

vim /etc/zabbix/zabbix_server.confLogFile=/var/log/zabbix/zabbix_server.logLogFileSize=0PidFile=/var/run/zabbix/zabbix_server.pidSocketDir=/var/run/zabbixDBHost=localhostDBName=zabbixDBUser=zabbixDBPassword=zabbixDBPort=3306SNMPTrapperFile=/var/log/snmptrap/snmptrap.logCacheSize=1024MTimeout=4AlertScriptsPath=/usr/lib/zabbix/alertscriptsExternalScripts=/usr/lib/zabbix/externalscriptsLogSlowQueries=3000

可选不配置

9.配置zabbix-agent

vi /etc/zabbix/zabbix_agentd.conf#配置zabbix server 的ipPidFile=/var/run/zabbix/zabbix_agentd.pidLogFile=/var/log/zabbix/zabbix_agentd.logLogFileSize=0Server=ListenPort=10050ServerActive=Hostname=Include=/etc/zabbix/zabbix_agentd.d/

10.改PHP 设置

修改php.ini为zabbix 建议的设置

编辑文件 php.ini

vi /etc/php.ini#设置为以下参数max_execution_time = 600max_input_time = 600memory_limit = 256post_max_size = 32Mupload_max_filesize = 16Mdate.timezone = Asia/Shanghai

11.修改Firewall 和SELinux 设置

a. 开放zabbix端口10050 、10051

（防火墙关闭可忽略）

firewall-cmd --permanent --add-port=10050/tcpfirewall-cmd --permanent --add-port=10051/tcp

b. 重启firewall

systemctl restart firewalld

c. 如果使用 SELinux, 运行以下命令使 Apache 可以和 Zabbix通信

setsebool -P httpd_can_connect_zabbix=1

d.启动zabbix-server 和zabbix-agent。重启httpd,，并设置zabbix-server和zabbix-agent开机自动启动

systemctl start zabbix-serversystemctl enable zabbix-serversystemctl start zabbix-agentsystemctl enable zabbix-agentsystemctl restart httpdsystemctl enable httpdsystemctl restart mysqldsystemctl enable mysqld

四.zabbix web首次登陆

输入

http://zabbi地址/zabbix

http://192.168.0.166/zabbix

密码是之前设置的zabbix

名字随意  可不写

默认的用户是admin
