zabbix應用搭建

1.yum安裝zabbix
1.1使用MySQL數據庫安裝存儲庫repo文件

[root@localhost ~]# yum -y install wget
[root@localhost ~]# rpm -i https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
warning: /var/tmp/rpm-tmp.6aQiSY: Header V4 RSA/SHA512 Signature, key ID a14fe591: NOKEY

1.2安裝Zabbix服務，前端，代理

[root@localhost yum.repos.d]# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent
[root@bogon ~]# yum install zabbix-get.x86_64

1.3.安裝數據庫mysql5.7.20

#!/bin/bash
#author:pan
#切換到相應文件夾
cd 
#二進制安裝mysql5.7.20
tar xvf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz -C /usr/local
cd /usr/local/
mv mysql-5.7.20-linux-glibc2.12-x86_64/ mysql
cd /usr/local/mysql/
mkdir -p data log binlogs run
cd /usr/local/
#添加用戶
useradd -M -s /sbin/nologin mysql
#更改屬主
chown -R mysql.mysql mysql
#添加路徑
ln -s /usr/local/mysql/bin/* /usr/local/bin/
#刪除原my.cnf
rm -f /etc/my.cnf
#創建my.cnf

1.4創建賬號

1.5導入數據庫

[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix -h192.168.9.22
Enter password:

1.6配置zabbix-server.conf
#如果此處用的是服務3的數據庫腳本，則別忘了更改數據庫的sock位置/app/mysql5.7/mysql.sock和port端口2297

[root@localhost ~]# cat -n /etc/zabbix/zabbix_server.conf | sed -n '12p;38p;101p;117p;125p;132p;140p;164p;203p;346p;490p'
12 ListenPort=10051 監聽端口
38 LogFile=/var/log/zabbix/zabbix_server.log 日誌路徑
101 DBName=zabbix 數據庫的數據庫名
117 DBUser=zabbix 數據庫的用戶
125 DBPassword=000000
132 DBSocket=/usr/local/mysql/run/mysql.sock
140 DBPort=3306
164 StartPollers=5
203 StartTrappers=10
346 ListenIP=0.0.0.0
490 AlertScriptsPath=/usr/lib/zabbix/alertscripts

1.7爲Zabbix前端配置PHP

[root@localhost ~]# cat -n /etc/httpd/conf.d/zabbix.conf |grep 20
20 php_value date.timezone Asia/Shanghai

1.8 啓動Zabbix服務器和代理進程

[root@localhost ~]# systemctl restart zabbix-server zabbix-agent httpd
[root@localhost ~]# systemctl enable zabbix-server zabbix-agent httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

2.基礎配置zabbix

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0

2.1

2.2

2.3

2.4

2.5

2.6

2.7

登陸 name：Admin pwd: zabbix

2.8

2.9解決亂碼問題

[root@localhost ~]# cd /usr/share/zabbix/fonts/
[root@localhost fonts]# ls
graphfont.ttf
[root@localhost fonts]# rz -E #上傳黑體的ttf
rz waiting to receive.
[root@localhost fonts]# ls
graphfont.ttf simhei.ttf
[root@localhost fonts]# cp graphfont.ttf{,.bak}
[root@localhost fonts]# ls
graphfont.ttf graphfont.ttf.bak simhei.ttf
[root@localhost fonts]# mv simhei.ttf graphfont.ttf
mv: overwrite ‘graphfont.ttf’? y
[root@localhost fonts]# ls
graphfont.ttf graphfont.ttf.bak

3.zaibbix-agent配置
3.1下載agent端

[root@localhost ~]# rpm -i https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
warning: /var/tmp/rpm-tmp.6aQiSY: Header V4 RSA/SHA512 Signature, key ID a14fe591: NOKEY

3.2安裝Zabbix客戶端

[root@localhost yum.repos.d]# yum -y install zabbix-agent

[root@bogon yum.repos.d]# cat -n /etc/zabbix/zabbix_agentd.conf | sed -n '13p;32p;97p;105p;122p;138p;149p;267p;286p'
13 PidFile=/var/run/zabbix/zabbix_agentd.pid #進程pid存放路徑
32 LogFile=/var/log/zabbix/zabbix_agentd.log #zabbix agent日誌存放路徑
97 Server=192.168.9.22 #指定zabbix server端IP地址 此處我根據實際情況改爲了Server=192.168.9.22
105 ListenPort=10050 #指定agentd的監聽端口
122 StartAgents=3 #指定啓動agentd進程數量。設置0表示關閉
138 ServerActive=192.168.9.22:10051 #啓用agnetd主動模式，啓動主動模式後，agentd將主動將收集到的數據發送到zabbix server端，Server Active後面指定的IP就是zabbix server端IP
149 Hostname=192.168.9.14 #需要監控服務器的主機名或者IP地址，此選項的設置一定要和zabbix web端主機配置中對應的主機名一致
267 Include=/etc/zabbix/zabbix_agentd.d/ #相關配置都可以放到此目錄下，自動生效
286 UnsafeUserParameters=1 #啓用agent端自定義item功能，設置此參數爲1後，就可以使用UserParameter指令了。UserParameter用於自定義item

---

此149條很重要****
此hostname爲agent的hostname或ip

也可以打開HostnameItem功能，設置自己獲取hostname

[root@zabbix-agent zabbix]# hostname
zabbix-agent
但不管怎麼樣，此處設置hostname或ip在以後建主機時也必須是這個名字，決不能錯

3.3啓動zabbix-agent

[root@bogon yum.repos.d]# systemctl start zabbix-agent
[root@bogon yum.repos.d]# which ss
/usr/sbin/ss
[root@bogon yum.repos.d]# ss -antup|grep 10050
tcp LISTEN 0 128 :10050 : users:(("zabbix_agentd",pid=2201,fd=4),("zabbix_agentd",pid=2200,fd=4),("zabbix_agentd",pid=2199,fd=4),("zabbix_agentd",pid=2198,fd=4),("zabbix_agentd",pid=2197,fd=4),("zabbix_agentd",pid=2196,fd=4))
tcp LISTEN 0 128 :::10050 ::: users:(("zabbix_agentd",pid=2201,fd=5),("zabbix_agentd",pid=2200,fd=5),("zabbix_agentd",pid=2199,fd=5),("zabbix_agentd",pid=2198,fd=5),("zabbix_agentd",pid=2197,fd=5),("zabbix_agentd",pid=2196,fd=5))

3.4在zabbix-server測試連通性，如果不通查看防火牆

[root@bogon share]# zabbix_get -s 192.168.9.14 -p 10050 -k "system.uptime"
14846

3.5在web上添加監控服務器

3.6查看連接

zabbix基礎部分到此結束
