Zabbix-(一) 安裝與部署

Zabbix-(一)安裝與部署

一.前言

本文記錄在Centos7.6平臺 經過yum安裝部署Zabbix 4.4

準備

• Centos7.6 虛擬機一臺(ip: 192.168.152.140)

• Mysql 8.0.12數據庫(ip: 192.168.152.1)

二.安裝

1.安裝php

yum安裝php

# yum install -y php

2.安裝httpd

yum安裝httpd

# yum install -y httpd

3. 安裝zabbix各組件

1. 添加rpm包

   # rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

2. 安裝zabbix-server-mysql

   # yum install -y zabbix-server-mysql

3. 安裝zabbix-web-mysql

   # yum install -y zabbix-web-mysql

4. 安裝zabbix-agent

   # yum install -y zabbix-agent

三.初始化zabbix數據庫

1. mysql建立zabbix用戶，密碼爲zabbix

   CREATE USER 'zabbix'@'%' IDENTIFIED BY 'zabbix';

2. 建立zabbix數據庫，併爲zabbix用戶賦予權限

   CREATE DATABASE zabbix DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_bin;
   
   GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'%';

3. 初始化schema

   注: zabbix sql在下面的這個路徑

   /usr/share/doc/zabbix-server-mysql-4.4.0/create.sql.gz

   a. 若是zabbix主機安裝了mysql-client那麼能夠向mysql寫入初始化sql

   # zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -h192.168.152.1 -uzabbix -p zabbix

   b. 若是zabbix沒有安裝mysql-client，那麼則能夠將create.sql.gz文件導出，再執行sql，這裏就不在贅述

四.配置zabbix

1. 配置zabbix-server

   # vim /etc/zabbix/zabbix_server.conf

   能夠修改server相關配置，例如：端口，日誌，SSL，數據庫，告警腳本路徑等

   這裏修改數據庫配置和容許的ip

   DBHost=192.168.152.1
   DBName=zabbix
   DBUser=zabbix
   DBPassword=zabbix
   DBPort=3306
   
   StatsAllowedIP=0.0.0.0/0

2. 配置zabbix前端

   # vim /etc/httpd/conf.d/zabbix.conf

   # 修改時區
   php_value date.timezone Asia/Shanghai

3. SELinux 配置

   # setsebool -P httpd_can_network_connect on
   # setsebool -P zabbix_can_network on
   # service httpd restart

4. zabbix-agent配置

   # vim /etc/zabbix/zabbix_agentd.conf

   # zabbix server地址
   Server=192.168.152.140
   
   ServerActive=192.168.152.140
   
   Hostname=Zabbix-server

五.啓動zabbix

1. 啓動zabbix-server和httpd

   # systemctl restart zabbix-server httpd

2. 啓動zabbix-agent

   # systemctl start zabbix-agent

六.訪問zabbix界面

訪問 http://192.168.152.140/zabbix/

七.其餘

部署問題

1. mysql zabbix 帳號問題，啓動zabbix-server時，出現了

   9213:20191029:144309.734 [Z3001] connection to database 'zabbix' failed: [2059] Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

   解決: 修改zabbix帳號

   ALTER USER 'zabbix'@'%' IDENTIFIED WITH mysql_native_password BY 'zabbix';

2. 未關閉selinux，出現

   10947:20191029:145011.030 cannot start preprocessing service: Cannot bind socket to "/var/run/zabbix/zabbix_server_preprocessing.sock": [13] Permission denied.

   解決:臨時關閉selinux

   # setenforce 0
