一、zabbix 安裝

<i id='kmhwv'></i>

1. zabbix下載地址

//repo.zabbix.com/zabbix

2. 安裝zabbix server

rpm -Uvh //repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.e7.noarch.rpm

yum clean all

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

3. 安裝zabbix agent

zabbix server端必須要安裝一個zabbix agent。

[root]# yum install zabbix-agent -y       

[root]# vi /etc/zabbix/zabbix_agentd.con f

PidFile=/run/zabbix/zabbix_server.pid     

LogFile=/var/log/zabbix/zabbix_agentd.log 

LogFileSize=0                             

Server=x.x.x.x                     

ServerActive=x.x.x.x:10051         

Hostname=zabbix-server                    

Include=/etc/zabbix/zabbix_agentd.d/*.conf

BufferSize=200                            

Timeout=30                            

二、MySQL安裝

1.創建mysql文件夾

cd /usr/local

mkdir mysql

2.下載資源完整包，并上傳到/usr/local/mysql

3.解壓mysql下載包

tar -xvf mysql-8.0.26-1.el7.x86_64.rpm-bundle.tar

4.查詢本地有沒有已存在安裝包和卸載

查詢：rpm -qa | grep mariadb

卸載：rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64 --nodeps

5. 安裝順序

rpm -ivh mysql-community-common-8.0.26-1.el7.x86_64.rpm        

rpm -ivh mysql-community-client-plugins-8.0.26-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-8.0.26-1.el7.x86_64.rpm         

rpm -ivh mysql-community-client-8.0.26-1.el7.x86_64.rpm       

rpm -ivh mysql-community-server-8.0.26-1.el7.x86_64.rpm       

rpm -ivh mysql-community-libs-compat-8.0.26-1.el7.x86_64.rpm  

6.開啟mysql

systemctl start mysqld

7.查看數據庫的初始密碼，命令如下：

cat /var/log/mysqld.log | grep password（記錄一下密碼，修改要用）

8.修改密碼

登錄：mysql -u root -p

修改：ALTER USER "USER"@"localhost" IDENTIFIED  BY "PASSWORD";

三、配置zabbix server

1.導入表，創建zabbix庫、zabbix用戶、導入zabbix數據

SQL> create database zabbix character set utf8 collate utf8_bin;     

SQL> create user 'USER'@'%' identified by 'PASSWORD';          

SQL> grant all privileges on zabbix.* to 'USER'@'%';               

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

2.配置zabbix-server連接mysql

[root]# vi /etc/zabbix/zabbix_server.conf

LogFile=/var/log/zabbix/zabbix_server.log

LogFileSize=0

PidFile=/run/zabbix/zabbix_server.pid （要和service里的路徑一樣）

SocketDir=/var/run/zabbix

DBHost=localhost （這里，localhost還是127.0.0.1視情況而定）

DBName=zabbix

DBUser=zabbix

DBPassword=PASSWORD

SNMPTrapperFile=/var/log/snmptrap/snmptrap.log

Timeout=4

AlertScriptsPath=/usr/lib/zabbix/alertscripts

ExternalScripts=/usr/lib/zabbix/externalscripts

LogSlowQueries=3000

3.啟動zabbix server

[root]# systemctl start zabbix-server

[root]# systemctl enable zabbix-server

4.修改zabbix前端PHP配置

修改時區

[root]# vi /etc/httpd/conf.d/zabbix.conf

php_value date.timezone Asia/Shanghai

5.關閉firewall、selinux

systemctl stop firewalld.service

systemctl disable firewalld.service

vi /etc/selinux/config

將SELINUX改成disable（重啟后生效）

6.啟動httpd服務

[root]# vi /etc/httpd/conf

修改ServerName x.x.x.x:80 (同zabbix_agentd.conf中的server地址)

[root]# systemctl start httpd

[root]# systemctl enable httpd

7.登錄zabbix web

//x.x.x.x/zabbix    

初始：Admin/zabbix  

界面右上角 用戶-修改密碼為PASSWORD    語言改為中文。

四、web端配置

1.創建主機

配置--主機--創建主機

2.配置加密

配置--主機--選擇一臺主機--加密

共享密鑰一致性：TEST

PSK：****************************************************

五、常見報錯

1、mysql客戶端連接失敗：2059-Authentication plugin 'caching_sha2_password' can not be loaded: ...

解決方法：登錄數據庫后

use mysql

select user,host,plugin,authentication_string from user;

alter user 'USER'@'%' identified with mysql_native_password by 'PASSWORD';

2、zabbix web出現403錯誤。

vi /etc/httpd/conf

查看ServerName x.x.x.x:80有沒有成功添加

3、登錄時顯示Unable to select configuration.

出現這個錯誤是數據庫表導入失敗。刪除zabbix庫和zabbix用戶以后重新執行導入表，創建zabbix庫、zabbix用戶、導入zabbix數據

SQL> create database zabbix character set utf8 collate utf8_bin;     

SQL> create user 'USER'@'%' identified by 'PASSWORD';          

SQL> grant all privileges on zabbix.* to 'USER'@'%';               

[root]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix  （過程有一點長，不要中斷）
