Zabbix概述

Zabbix是一款能够监控各种网络参数以及服务器健康性和完整性的软件。Zabbix使用灵活的通知机制，允许用户为几乎任何事件配置基于邮件的告警。这样可以快速反馈服务器的问题。基于已存储的数据，Zabbix提供了出色的报告和数据可视化功能。

Zabbix 基础架构

Zabbix部署

集群规划

进程hadoop102节点hadoop103节点hadoop104节点
zabbix-agent√√√
zabbix-server√
MySQL√
zabbix-web√

准备工作

关闭集群

如果集群开启，先关闭集群。因为安装Zabbix前，需要重启虚拟机。

[root@hadoop102 ~]$ cluster.sh stop

关闭防火墙（3台节点，已关闭）

[root@hadoop102 ~]$ sudo service iptables stop
[root@hadoop102 ~]$ sudo chkconfig iptables off

[root@hadoop103 ~]$ sudo service iptables stop
[root@hadoop103 ~]$ sudo chkconfig iptables off

[root@hadoop104 ~]$ sudo service iptables stop
[root@hadoop104 ~]$ sudo chkconfig iptables off

关闭SELinux（hadoop102）

1）修改配置文件/etc/selinux/config

[root@hadoop102 ~]$ sudo vim /etc/selinux/config

修改如下内容

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2）重启服务器

[root@hadoop102 ~]$  sudo reboot

安装yum仓库

1）安装zabbix的yum仓库

[root@hadoop102 ~]$ sudo rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

[root@hadoop103 ~]$ sudo rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

[root@hadoop104 ~]$ sudo rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

2）安装Software Collections仓库

[root@hadoop102 ~]$ sudo yum install -y centos-release-scl

[root@hadoop103 ~]$ sudo yum install -y centos-release-scl

[root@hadoop104 ~]$ sudo yum install -y centos-release-scl

修改zabbix仓库配置文件

hadoop102、hadoop103、hadoop104三台节点，依次执行如下步骤。
1）修改为阿里云镜像
（1）查看原始zabbix.repo文件

[root@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo

查看内容如下

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

（2）执行以下命令完成全局替换

[root@hadoop102 ~]$ sudo sed -i 's/http:\/\/repo.zabbix.com/https:\/\/mirrors.aliyun.com\/zabbix/g' /etc/yum.repos.d/zabbix.repo

（3）查看修改之后的zabbix.repo文件

[root@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo

查看内容如下

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/frontend
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

2）启用zabbix-web仓库（hadoop102）
打开/etc/yum.repos.d/zabbix.repo文件，做如下修改

cat /etc/yum.repos.d/zabbix.repo

修改内容：[zabbix-frontend]下的enabled=1

[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/frontend
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

安装Zabbix

在hadoop102、hadoop103、hadoop104三台节点分别执行以下安装命令

[root@hadoop102 ~]$ sudo yum install -y zabbix-server-mysql zabbix-agent zabbix-web-mysql-scl zabbix-apache-conf-scl

[root@hadoop103 ~]$ sudo yum install -y zabbix-agent

[root@hadoop104 ~]$ sudo yum install -y zabbix-agent

配置Zabbix

创建zabbix数据库

[root@hadoop102 ~]$ mysql -uroot -p000000 -e"create database zabbix character set utf8 collate utf8_bin"

导入Zabbix建表语句

[root@hadoop102 ~]$ zcat /usr/share/doc/zabbix-server-mysql-5.0.9/create.sql.gz | mysql -uroot -p000000 zabbix

会出现如下错误：

gzip: /usr/share/doc/zabbix-server-mysql-5.0.9/create.sql.gz: No such file or directory

则输入如下语句

[root@hadoop102 ~]$ zcat /usr/share/doc/zabbix-server-mysql-5.0.*/create.sql.gz | mysql -uroot -p000000 zabbix

配置Zabbix_Server（hadoop102）

修改zabbix-server配置文件

[root@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_server.conf

DBHost=hadoop102
DBName=zabbix
DBUser=root
DBPassword=000000

配置Zabbix_Agent（三台节点）

修改zabbix-agent配置文件

[root@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf

修改如下内容：

Server=hadoop102
#ServerActive=127.0.0.1
#Hostname=Zabbix server

配置Zabbix_Web时区

修改/etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf文件

[root@hadoop102 ~]$ sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

修改如下内容：

[zabbix]
user = apache
group = apache

listen = /var/opt/rh/rh-php72/run/php-fpm/zabbix.sock
listen.acl_users = apache
listen.allowed_clients = 127.0.0.1

pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

php_value[session.save_handler] = files
php_value[session.save_path]    = /var/opt/rh/rh-php72/lib/php/session/

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[max_input_vars] = 10000
php_value[date.timezone] = Asia/Shanghai
