Zabbix三種架構(gòu)

Server-Agent

Server-Node-Agent

Server-Proxy-Agent

配置介紹

Zabbix Proxy的配置

• Server-Node-Agent
• Server-Proxy-Agent

1、配置proxy主機

① 安裝相應的zabbix包

zabbix-proxy-mysql zabbix-get zabbix-agent zabbix-sender

② 準備數(shù)據(jù)庫

創(chuàng)建、授權用戶、導入schema.sql

③ 修改配置文件

④ 在server端添加此Proxy

Administration ——> Proxies

⑤ 在Server端配置通過此Proxy監(jiān)控的主機

<font color =red>注意：zabbix agent端要允許zabbix proxy主機執(zhí)行數(shù)據(jù)采集操作</font>

實戰(zhàn)演練—分布式監(jiān)控

實驗部署架構(gòu)

1、實驗前期準備(Server端、Proxy端)

• 配置服務端和代理端時間同步

  # 服務端和代理端安裝ntpdate服務包
  yum install -y ntpdate
  # 服務端和代理端同步阿里云時間服務器
  ntpdate ntp1.aliyun.com

• 關閉防火墻、SELinux安全模式

  systemctl stop firewalld
  systemctl disable firewalld
  setenforce 0
  getenforce
  iptables -nL

• 設置主機名

  [root@zabbix-server ~]# hostnamectl set-hostname zabbix-server 
  [root@zabbix-proxy ~]# hostnamectl set-hostname zbxproxy.xybdiy.com
  [root@zabbix-agent-02 ~]# hostnamectl set-hostname zabbix-agent-02

• 配置域名解析

  [root@zabbix-agent-02 ~]# cat /etc/hosts
  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  192.168.200.60  zabbix-server
  192.168.200.90  zbxproxy.xybdiy.com zbxproxy
  192.168.200.100 zabbix-agent-02

  zabbix-server 直接監(jiān)控一臺主機zabbix-agent-centos

  zabbix-server 通過代理zbproxy 監(jiān)控zabbix-agent-02

2、在代理服務器上配置MySQL

• 創(chuàng)建MariaDB.repo

[root@zbproxy yum.repos.d]# vim mariadb.repo
[root@zbproxy yum.repos.d]# cat mariadb.repo
[mariadb]
name = MariaDB
baseurl = http://mirrors.ustc.edu.cn/mariadb/yum/10.2/centos7-amd64/
gpgkey=http://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1

• 安裝mariadb

[root@zbproxy ~]# yum install -y MariaDB-server MariaDB-client

• 修改數(shù)據(jù)庫配置文件

[root@zbproxy ~]# vim /etc/my.cnf.d/server.cnf 
[mysqld]
skip_name_resolve = ON            # 跳過主機名解析
innodb_file_per_table = ON        # 開啟獨立表空間
innodb_buffer_pool_size = 256M    # 緩存池大小
max_connections = 2000            # 最大連接數(shù)
log-bin = master-log            # 開啟二進制日志

• 啟動數(shù)據(jù)庫服務

[root@zbproxy ~]# systemctl start mariadb
[root@zbproxy ~]# systemctl enable mariadb

• 初始化數(shù)據(jù)庫

[root@zbproxy ~]# mysql_secure_installation 
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): 
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y     
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
 ... Success!
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
 ... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
 ... Success!
Cleaning up...
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
[root@zbproxy ~]# mysql -uroot -p000

• 創(chuàng)建數(shù)據(jù)庫 和 授權用戶

# 創(chuàng)建數(shù)據(jù)庫zbxproxydb
MariaDB [(none)]> create database zbxproxydb character set 'utf8';
Query OK, 1 row affected (0.00 sec)
# 授權用戶zbxproxydb

# 刷新，重新加載
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
# 退出
MariaDB [(none)]> exit
Bye
[root@zbproxy ~]#

3、在代理服務器上下載zabbix相應的包。

主要是代理proxy的包

[root@zbproxy src]# yum localinstall zabbix-agent-5.0.20-1.el7.x86_64.rpm zabbix-proxy-mysql-5.0.20-1.el7.x86_64.rpm zabbix-get-5.0.20-1.el7.x86_64.rpm zabbix-sender-5.0.20-1.el7.x86_64.rpm

• 初始化數(shù)據(jù)庫

#查詢數(shù)據(jù)庫包
[root@zbproxy src]# rpm -ql zabbix-proxy-mysql
/etc/logrotate.d/zabbix-proxy
/etc/zabbix/zabbix_proxy.conf
/usr/lib/systemd/system/zabbix-proxy.service

/usr/share/man/man8/zabbix_proxy.8.gz
/var/log/zabbix
/var/run/zabbix

zabbix-proxymysql 包里帶有導入數(shù)據(jù)的文件schema.sql.gz

# 復制schema.sql.gz
[root@zbproxy ~]# cp /usr/share/doc/zabbix-proxy-mysql-5.0.20/schema.sql.gz .
[root@zbproxy ~]# ls
anaconda-ks.cfg  schema.sql.gz
# 解壓
[root@zbproxy ~]# gzip -d schema.sql.gz 
[root@zbproxy ~]# ls
anaconda-ks.cfg  schema.sql
# 導入數(shù)據(jù)，出現(xiàn)以下問題
[root@zbproxy ~]# mysql -uroot -p000 < schema.sql 
ERROR 1046 (3D000) at line 1: No database selected
解決辦法：
[root@zbproxy ~]# vim schema.sql 
在首部添加如下內(nèi)容：
USE zbxproxydb;
按:wq保存退出
[root@zbproxy ~]# mysql -uroot -p000 < schema.sql

4、配置proxy端

[root@zbproxy ~]# vim /etc/zabbix/zabbix_proxy.conf 
Server=192.168.200.60            # server 的IP
ServerPort=10051                # server 的端口
Hostname=zbxproxy.xybdiy.com    # 主機名
ListenPort=10051                # proxy自己的監(jiān)聽端口
EnableRemoteCommands=1            # 允許遠程命令
LogRemoteCommands=1                # 記錄遠程命令的日志
DBHost=192.168.200.90
DBName=zbxproxydb
DBUser=zbxproxyuser
DBPassword=zbxproxypass
ConfigFrequency=30                # 意思是多長時間去服務端拖一次有自己監(jiān)控的操作配置，為了實驗更快的生效。這里設置30秒，默認3600s
DataSenderFrequency=1            # 每一秒向server 端發(fā)一次數(shù)據(jù)，發(fā)送頻度

開啟proxy服務

[root@zbxproxy zabbix]# systemctl start zabbix-proxy
[root@zbxproxy zabbix]# systemctl enable zabbix-proxy

5、配置Agent端允許proxy代理監(jiān)控

[root@zabbix-agent-02 ~]# vim /etc/zabbix/zabbix_agentd.conf 
Server=192.168.200.60,192.168.200.90
ServerActive=192.168.200.60,192.168.200.90
[root@zabbix-agent-02 ~]# systemctl restart zabbix-agent
