zabbix分散式架構
架構
- zaibbix_server安裝及配置
一、安裝環境
1、OS環境
CentOS 7.4
office ip:172.16.65.149
prod ip:10.100.1.15
2、安裝基礎環境
rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
[[email protected] yum.repos.d]# cat zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/3.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
[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
yum install mysql-devel gcc net-snmp-devel curl-devel perl-DBI php-gd php-mysql php-bcmath php-mbstring php-xml -y
1、安裝配置資料庫
yum -y install mariadb-server
2、資料庫開機自啟動
systemctl enable mariadb
3、啟動資料庫
systemctl start mariadb
4、初始化資料庫
mysql_secure_installation
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: 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] Y
... Success!
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!
5、建立zabbix資料庫、使用者及密碼
mysql -uroot -pPASSWORD -e "create database zabbix default character set utf8 collate utf8_bin;"
mysql -uroot -pPASSWORD -e "grant all on zabbix.* to 'zabbix'@'%' identified by 'XXXXXX';"
6、資料庫登入測試
[[email protected] yum.repos.d]# mysql -uzabbix -pXXXXXX
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 16
Server version: 5.5.56-MariaDB MariaDB Server
Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> show databases;

+--------------------+
2 rows in set (0.00 sec)
MariaDB [(none)]> use zabbix
Database changed
MariaDB [zabbix]> show tables
-> ;
Empty set (0.00 sec)
三、安裝zabbix伺服器端
1、安裝zabbix服務
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get
2、匯入zabbix資料表結構
cd /usr/share/doc/zabbix-server-mysql-3.0.14
[[email protected] zabbix-server-mysql-3.0.14]# gzip -d create.sql.gz
[[email protected] zabbix-server-mysql-3.0.14]# cat create.sql | mysql -uzabbix -pXXXXXX zabbix
3、配置zabbix配置檔案
[[email protected] ~]# cp /etc/zabbix/zabbix_server.conf{,.bak}
[[email protected] ~]# vim /etc/zabbix/zabbix_server.conf
LogFileSize=1024
DBPassword=XXXXXX
CacheSize=1024M
定義時區
[[email protected] ~]# cp /etc/httpd/conf.d/zabbix.conf{,.bak}
[[email protected] ~]# vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
4、開啟zabbix並設定為開機自啟動
[[email protected] ~]# systemctl enable zabbix-server
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/z
abbix-server.service.[[email protected] ~]# systemctl start zabbix-server
[[email protected] ~]# systemctl status zabbix-server
● zabbix-server.service - Zabbix Server

5、啟動http並設定開機自啟動
[[email protected] ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.ser
vice.[[email protected] ~]# systemctl start httpd

四、進入web管理介面配置
http://172.16.65.149/zabbix
所有檢測均OK
zabbix管理網頁初始賬號密碼
Admin
zabbix
五、監控交換機配置
交換機SNMP配置
snmp-server community xxxxx ro
snmp-server community xxxxx rw
linux上安裝net-snmp net-snmp-tuils包測試snmp訪問
[[email protected] ~]# yum -y install net-snmp net-snmp-utils
snmpwalk -v 2c -c mflexnpm 10.100.0.46 1.3.6.1.2.1.2.2.1.10.1 檢視埠1的計數
[[email protected] ~]# snmpwalk -v 2c -c xxxxxx 10.100.0.46 1.3.6.1.2.1.2.2.1.10.1
IF-MIB::ifInOctets.1 = Counter32: 1998
在zabbix上將snmp的變數加入

- zabbix_proxy安裝
軟體安裝
rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
cat /etc/yum.repos.d/zabbix.repo
yum -y install -y zabbix-proxy zabbix-proxy-mysql mariadb-server
建立資料庫
systemctl enable mariadb
systemctl start mariadb
mysql_secure_installation
mysql -uroot -pPASSWORD -e "create database zabbix_proxy default character set utf8 collate utf8_bin;"
mysql -uroot -pPASSWORD -e "grant all on zabbix_proxy.* to 'zabbix_proxy'@'%' identified by 'XXXXXX';"
cd /usr/share/doc/zabbix-proxy-mysql-3.0.14
zcat schema.sql.gz | mysql -uzabbix_proxy -pXXXXXX zabbix_proxy
proxy配置檔案修改
cp /etc/zabbix/zabbix_proxy.conf{,.bak}
[[email protected] ~]# grep '^[a-Z]' /etc/zabbix/zabbix_proxy.conf
