Centos7安裝zabbix4.4.1和grafana7.1.1
阿新 • • 發佈：2021-11-21
這裡使用的的yum安裝的
先關閉selinux和防火牆，然後重啟伺服器。
安裝zabbix
#下載yum源 wget http://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm #安裝原始碼庫 rpm -ivh zabbix-release-4.4-1.el7.noarch.rpm #安裝Zabbix部署包 yum -y install zabbix-agent zabbix-get zabbix-server-mysql zabbix-sender zabbix-web zabbix-web-mysql
安裝資料庫
#下載mysql原始碼包
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
#安裝mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm -y
#安裝MySQL5.7
yum install mysql-community-server -y
#啟動服務
systemctl enable --now mysqld
#修改root本地登入密碼
#mysql安裝完成之後，在/var/log/mysqld.log檔案中給root生成了一個預設密碼。通過下面的方式找到root預設密碼.
[root@localhost ~]# grep 'password' /var/log/mysqld.log
2021-11-19T17:21:41.433493Z 1 [Note] A temporary password is generated for root@localhost: QjEg/pll6N(c
#登入mysql修改密碼
#mysql5.7預設安裝了密碼安全檢查外掛（validate_password），預設密碼檢查策略要求密碼必須包含：大小寫字母、數字和特殊符號，並且長度不能少於8位
[root@localhost ~]# mysql -uroot -p
Enter password:

+----------------------------------------+-----------------+
validate_password_policy：密碼策略，預設為MEDIUM策略
validate_password_dictionary_file：密碼策略檔案，策略為STRONG才需要
validate_password_length：密碼最少長度
validate_password_mixed_case_count：大小寫字元長度，至少1個
validate_password_number_count ：數字至少1個
validate_password_special_char_count：特殊字元至少1個
#修改密碼策略
在/etc/my.cnf檔案新增validate_password_policy配置，指定密碼策略
選擇0（LOW），1（MEDIUM），2（STRONG）其中一種，選擇2需要提供密碼字典檔案
validate_password_policy=0
如果不需要密碼策略，新增my.cnf檔案中新增如下配置禁用即可
validate_password = off
重新啟動mysql服務使配置生效
修改/etc/my.cnf配置檔案，在[mysqld]下新增編碼配置
vim /etc/my.cnf [mysqld] character_set_server=utf8 init_connect='SET NAMES utf8' #重啟服務，檢視資料庫預設編碼 systemctl restart mysqld [root@localhost ~]# mysql -uroot -pPasswd123! -e "show variables like '%character%'" mysql: [Warning] Using a password on the command line interface can be insecure. +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ #建立zabbix資料庫及其使用者 mysql -uroot -pPasswd123! -e "create database zabbix default character set utf8 collate utf8_bin" mysql -uroot -pPasswd123! -e "grant all on zabbix.* to 'zabbix'@'%' identified by 'zabbix'" #測試zabbix使用者是否能夠連線 [root@localhost ~]# mysql -uzabbix -pzabbix mysql: [Warning] Using a password on the command line interface can be insecure.

匯入zabbix建庫指令碼
cd /usr/share/doc/zabbix-server-mysql-4.4.10/ zcat create.sql.gz| mysql -uzabbix -pzabbix zabbix
啟動Zabbix Server
在zabbix_server.conf中編輯資料庫配置
vim /etc/zabbix/zabbix_server.conf #新增配置 DBHost=192.168.248.135 DBName=zabbix DBUser=zabbix DBPassword=zabbix #啟動服務 systemctl enable --now zabbix-server
配置web GUI
#Zabbix前端的Apache配置檔案位於/etc/httpd/conf.d/zabbix.conf
vim /etc/httpd/conf.d/zabbix.conf

#啟動服務
systemctl enable --now httpd
安裝grafana
官方：https://grafana.com/grafana/download
#下載包 wget https://dl.grafana.com/enterprise/release/grafana-enterprise-7.1.1-1.x86_64.rpm #安裝 yum -y install grafana-enterprise-7.1.1-1.x86_64.rpm #啟動服務 systemctl enable --now grafana-server
測試訪問 ip:300
預設使用者和密碼：admin admin
安裝garfana-zabbix外掛#過濾出zabbix外掛 [root@localhost ~]# grafana-cli plugins list-remote|grep zabbix id: alexanderzobnin-zabbix-app version: 4.0.2 #安裝zabbix外掛 grafana-cli plugins install alexanderzobnin-zabbix-app 下載地址https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app/ [root@localhost ~]# ls /var/lib/grafana/plugins/ alexanderzobnin-zabbix-app-4.0.2.zip #解壓縮 cd /var/lib/grafana/plugins/ unzip alexanderzobnin-zabbix-app-4.0.2.zip #重啟grafana服務 systemctl restart grafana-server
登入到grafana上，啟用外掛
新增新資料來源
新增資料來源時，會發現找不到zabbix 修改grafana的配置，將zabbix外掛配置允許 找到 “;allow_loading_unsigned_plugins =“ 項，刪掉 “;“ ，加上 “alexanderzobnin-zabbix-datasource“
vim /etc/grafana/grafana.ini [plugins] .......... allow_loading_unsigned_plugins = alexanderzobnin-zabbix-datasource #重啟服務 systemctl restart grafana-server
再次新增就行
Name自定義，Type選擇Zabbix,Url填寫訪問zabbix-web的url（http://10.0.11.133/zabbix/api_jsonrpc.php），加上zabbix-api的php檔案，Zabbix API details使用者名稱密碼需要在Zabbix-web頁面中設定，也可以使用Zabbix的初始使用者
新增儀表盤
匯入模板
可以通過訪問https://grafana.com/dashboards來檢視已有儀表盤模板，選取合適的使用
我這邊已經匯入了所以會有報錯
應用匯入的模板
