最火的集群监控框架Zabbix，安装细节，附有截图

Zabbix安装

关闭集群

关闭防火墙

关闭SELinux

sudo vim /etc/selinux/config

修改文件内容

# 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

重启服务器

sudo reboot

配置Zabbix yum源（3台节点）

1）安装zabbix的yum仓库

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

sudo yum install -y centos-release-scl

修改zabbix仓库配置文件

1）修改为阿里云镜像

1）查看原始zabbix.repo文件

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

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

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

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

打开/etc/yum.repos.d/zabbix.repo文件，做如下修改

[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

102:

sudo yum install -y zabbix-server-mysql zabbix-agent zabbix-web-mysql-scl zabbix-apache-conf-scl

103:

sudo yum install -y zabbix-agent

配置Zabbix

创建zabbix数据库

mysql -uroot -p000000 -e"create database zabbix character set utf8 collate utf8_bin"

建表语句在/usr/share/doc/zabbix-server-mysql-5.0.18/目录下的create.sql.gz文件中

zcat /usr/share/doc/zabbix-server-mysql-5.0.18/create.sql.gz | mysql -uroot -p000000 zabbix

配置Zabbix_Server（hadoop102）

修改zabbix-server配置文件

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

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

sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

修改如下内容：

php_value[date.timezone] = Asia/Shanghai
