MYSQL 數據庫搭建Zabbix 監控

mysql安裝zabbix4.0

一 准備環境 

1.  關閉系統 selinux

[root@linux01 ~]#vi /etc/selinux/config  

#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.

設置完需重啟虛擬機

2. 設置此參數，不立即重啟主機時

#  setenforce 0

 

3. zabbix 安裝參考文檔

https://www.zabbix.com/documentation/4.0/manual/installation/install_from_packages/rhel_centos       ##zabbix   安裝文檔

二 安裝 

4.安裝rpm

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

5. 下載安裝文檔

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

6. 安裝 server 、 agent 端

yum install mysql-server httpd php

yum install zabbix-server-mysql zabbix-web-mysql

yum install zabbix-agent

7.  創建 zabbix 數據庫

> create database zabbix;                                          

8. zabbix數據庫中創建需要的表

    # cd /usr/share/doc/zabbix-server-mysql-4.0.0/

   # zcat create.sql.gz | mysql -uroot -pzabbix -S /home/mysql/mysqldb/db_master/mysql.sock zabbix

9. 數據庫創建用戶並授權

> create user zabbix@'10.0.0.69';

> grant all privileges on *.* to zabbix@'10.0.0.69' identified by 'oraclep';

> flush privileges;

> grant all privileges on *.* to zabbix@'localhost' identified by 'oraclep';

10. 編輯文件 zabbix_server.conf 加入 server 端信息

加入信息：

SocketDir=/var/run/zabbix

DBHost=10.0.0.53

DBName=zabbix

DBUser=zabbix

DBPasswd=oraclep

DBSocket=/home/mysql/mysqldb/db_slave/mysql.sock zabbix

DBPort=33333

11. 查看 /etc/zabbix/zabbix_server.conf

[root@localhost ~]# grep -v '^#' /etc/zabbix/zabbix_server.conf |grep -v '^$'

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

LogFileSize=0

PidFile=/var/run/zabbix/zabbix_server.pid

SocketDir=/var/run/zabbix

DBHost=10.0.0.53

DBName=zabbix

DBUser=zabbix

DBPasswd=oraclep

DBSocket=/home/mysql/mysqldb/db_slave/mysql.sock zabbix

DBPort=33333

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

Timeout=4

AlertScriptsPath=/usr/lib/zabbix/alertscripts

ExternalScripts=/usr/lib/zabbix/externalscripts

LogSlowQueries=3000

12.  測試以上信息正確性

# mysql -uzabbix -poraclep -S /home/mysql/mysqldb/db_master/mysql.sock -P 55555 ;

13. zabbix 啟動、關閉重啟

# systemctl restart zabbix-server

# systemctl start zabbix-server

# systemctl stop zabbix-server

# systemctl status zabbix-server

# systemctl start zabbix-agent

# systemctl stop zabbix-agent

 

14.  查看 zabbix 日志

[root@localhost ~]# tail -f /var/log/zabbix/zabbix_server.log

[root@localhost ~]# tail -f /var/log/zabbix/zabbix_agent.log

15.  修改時區：

vi  /etc/httpd/conf.d/zabbix.conf

依據所在時區，你可以取消 “ date.timezone ” 設置的注釋，並正確配置它。在配置文件更改后，需要重啟 Apache Web 服務器。

在此行下面添加

date.timezone = Asia/Shanghai

16.  創建 mysql 連接目錄

agent 端數據庫連接與密碼

[root@localhost zabbix]# mkdir -p /var/lib/zabbix

#   vi /var/lib/zabbix/.my.cnf

[client]

password=

user=root

socket=/home/mysql/mysqldb/db_master/mysql.sock

17.  編輯 /etc/zabbix/zabbix_agentd.d 加入 agent 端信息

# cd /etc/zabbix/zabbix_agentd.d

# vi userparameter_mysql.conf

UserParameter=mysql.status[*],echo "show global status where Variable_name='Binlog_cache_use';" | HOME=/var/lib/zabbix mysql -N | awk '{print $0}'

找出 HOME=/var/lib/zabbix mysql 測試

[root@localhost zabbix_agentd.d]# HOME=/var/lib/zabbix mysql        與 agent 端數據庫連接與密碼同一路徑

可以連接到數據庫

[root@localhost zabbix_agentd.d]# env|grep HOME

HOME=/root

18. 查看 /etc/zabbix/zabbix_agentd.conf 

[root@localhost ~]# grep -v '^#' /etc/zabbix/zabbix_agentd.conf |grep -v '^$'

PidFile=/var/run/zabbix/zabbix_agentd.pid

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

LogFileSize=0

Server=10.0.0.69

ServerActive=10.0.0.69

Hostname=localhost

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

 

19.web 網頁連接

# systemctl start httpd

# http://10.0.0.69/zabbix/setup.php
