zaibbix_server安裝及配置
1、安裝環境
一、OS環境
CentOS 7.4
office ip:172.16.65.149
prod ip:10.100.1.15
二、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
[root@XXXXprodm 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
2、服務端安裝
一、安裝配置數據庫
yum -y install mariadb-server
二、數據庫開機自啓動
systemctl enable mariadb
三、啓動數據庫
systemctl start mariadb
四、初始化數據庫
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
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] 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] Ymysql

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!
五、建立zabbix數據庫、用戶及密碼
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';"
六、數據庫登入測試
[root@XXXXrodm 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;
+--------------------+
| Database |

| zabbix |
+--------------------+
2 rows in set (0.00 sec)
MariaDB [(none)]> use zabbix
Database changed
MariaDB [zabbix]> show tables
-> ;
Empty set (0.00 sec)

3、安裝zabbix服務器端
一、安裝zabbix服務
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get
二、導入zabbix數據表結構
cd /usr/share/doc/zabbix-server-mysql-3.0.14
[root@XXX zabbix-server-mysql-3.0.14]# gzip -d create.sql.gz
[root@XXX zabbix-server-mysql-3.0.14]# cat create.sql | mysql -uzabbix -pXXXXXX zabbix
三、配置zabbix配置文件
[root@XXX ~]# cp /etc/zabbix/zabbix_server.conf{,.bak}
[root@XXX ~]# vim /etc/zabbix/zabbix_server.conf
LogFileSize=1024
DBPassword=XXXXXX
CacheSize=1024M
定義時區
[root@XXX ~]# cp /etc/httpd/conf.d/zabbix.conf{,.bak}
[root@XXX ~]# vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
四、開啓zabbix並設置爲開機自啓動
[root@XXX ~]# 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.[root@XXXprodm ~]# systemctl start zabbix-server
[root@XXX ~]# systemctl status zabbix-server
● zabbix-server.service - Zabbix Server

Hint: Some lines were ellipsized, use -l to show in full.
五、啓動http並設置開機自啓動
[root@ ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.ser
vice.[root@ ~]# systemctl start httpd
[root@ ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server

4、進入web管理界面配置
http://172.16.65.149/zabbix
web

全部檢測均OKsql

zabbix管理網頁初始帳號密碼
Admin
zabbix數據庫

5、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
[root@ ~]# 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 查看端口1的計數
[root@ ~]# 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的變量加入

zabbix_proxy安裝
軟件安裝
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
建立數據庫
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配置文件修改
cp /etc/zabbix/zabbix_proxy.conf{,.bak}

[root@XXXODPROXY ~]# grep '^[a-Z]' /etc/zabbix/zabbix_proxy.conf

在zabbix-server添加proxy
vim

server上添加解析

添加測試交換機
10.1.12.8

添加對zabbix_proxy的監控
一、zabbix-agent的安裝
yum install -y zabbix-agent
二、修改zabbix_agentd.conf
[root@xxxxxRODPROXY zabbix]# cat /etc/zabbix/zabbix_agentd.conf | grep '^[a-Z]'
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=1024
Server=172.16.65.147
ServerActive=172.16.65.149
Hostname=XXXRODPROXY
Include=/etc/zabbix/zabbix_agentd.d/
[root@xxxxxODPROXY ~]# cat /etc/zabbix/zabbix_agentd.conf | grep '^[a-Z]'
