集群监控——Zabbix

1 Zabbix部署

集群规划

 1.1 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。

[[email protected] ~]$ cluster.sh stop

关闭防火墙（3台节点，已关闭）

[[email protected] ~]$ sudo service iptables stop

[[email protected] ~]$ sudo chkconfig iptables off

[[email protected] ~]$ sudo service iptables stop

[[email protected] ~]$ sudo chkconfig iptables off

[[email protected] ~]$ sudo service iptables stop

[[email protected] ~]$ sudo chkconfig iptables off

闭SELinux（hadoop102）

1）修改配置文件/etc/selinux/config

[[email protected] ~]$ 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

[[email protected] ~]$  sudo reboot

1.2 配置Zabbix yum源

 安装yum仓库

1）安装zabbix的yum仓库

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

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

[[email protected]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

[[email protected]hadoop102 ~]$ sudo yum install -y centos-release-scl

[[email protected]hadoop103 ~]$ sudo yum install -y centos-release-scl

[[email protected]hadoop104 ~]$ sudo yum install -y centos-release-scl

安装完仓库，出现这三个文件

修改zabbix仓库配置文件

执行以下命令完成全局替换,三台都替换

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

启用zabbix-web仓库

打开/etc/yum.repos.d/zabbix.repo文件

[[email protected] yum.repos.d]$ vim zabbix.repo

 2 安装Zabbix

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

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

[[email protected]hadoop103 ~]$ sudo yum install -y zabbix-agent

[[email protected]hadoop104 ~]$ sudo yum install -y zabbix-agent

3 配置Zabbix

1)创建zabbix数据库

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

 2)导入Zabbix建表语句

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

 查看一下

 3）配置Zabbix_Server（hadoop102）

修改zabbix-server配置文件

[[email protected] ~]$ sudo vim /etc/zabbix/zabbix_server.conf

DBHost=hadoop102

DBName=zabbix

DBUser=root

DBPassword=000000

 4) 配置Zabbix_Agent（三台节点）

修改zabbix-agent配置文件

[[email protected] ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf

修改如下内容：

Server=hadoop102

#ServerActive=127.0.0.1

#Hostname=Zabbix server

 

 

5）配置Zabbix_Web时区

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

[[email protected] ~]$ sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

php_value[date.timezone] = Asia/Shanghai

4 启动停止Zabbix

4.1 启动Zabbix

[[email protected]hadoop102 ~]$ sudo systemctl start zabbix-server zabbix-agent httpd rh-php72-php-fpm

查看一下状态

[[email protected] ~]$ sudo systemctl status zabbix-server zabbix-agent httpd rh-php72-php-fpm

设置开机自启

[[email protected]hadoop102 ~]$ sudo systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

[[email protected]hadoop103 ~]$ sudo systemctl start zabbix-agent

[[email protected]hadoop103 ~]$ sudo systemctl enable zabbix-agent

[[email protected]hadoop104 ~]$ sudo systemctl start zabbix-agent

[[email protected]hadoop104 ~]$ sudo systemctl enable zabbix-agent

4.2 停止Zabbix

[[email protected]hadoop102 ~]$ sudo systemctl stop zabbix-server zabbix-agent httpd rh-php72-php-fpm

[[email protected]hadoop102 ~]$ sudo systemctl disable zabbix-server zabbix-agent httpd rh-php72-php-fpm

[[email protected]hadoop103 ~]$ sudo systemctl stop zabbix-agent

[[email protected]hadoop103 ~]$ sudo systemctl disable zabbix-agent

[[email protected]hadoop104 ~]$ sudo systemctl stop zabbix-agent

[[email protected]hadoop104 ~]$ sudo systemctl disable zabbix-agent

4.3 连接Zabbix_Web数据库

1）浏览器访问http://hadoop102/zabbix/

 2）检查配置

 3）配置数据库

 4）配置zabbix-server

 4.4 登录Zabbix

1）用户名密码如下

用户名：Admin     密码：zabbix

 

 2）点击User Settings，语言设成中文
