一.前言

本文记录在Centos7.6平台 通过yum安装部署Zabbix 4.4

准备

  • Centos7.6 虚拟机一台(ip: 192.168.152.140)
  • Mysql 8.0.12数据库(ip: 192.168.152.1)

二.安装

1.安装php

yum安装php

# yum install -y php

2.安装httpd

yum安装httpd

# yum install -y httpd

3. 安装zabbix各组件

  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. 安装zabbix-server-mysql
    # yum install -y zabbix-server-mysql
  3. 安装zabbix-web-mysql
    # yum install -y zabbix-web-mysql
  4. 安装zabbix-agent
    # yum install -y zabbix-agent

三.初始化zabbix数据库

  1. mysql创建zabbix用户,密码为zabbix
    CREATE USER 'zabbix'@'%' IDENTIFIED BY 'zabbix';
  2. 创建zabbix数据库,并为zabbix用户赋予权限
    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在下面的这个路径
    /usr/share/doc/zabbix-server-mysql-4.4.0/create.sql.gz

    a. 如果zabbix主机安装了mysql-client那么可以向mysql写入初始化sql

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

    b. 如果zabbix没有安装mysql-client,那么则可以将create.sql.gz文件导出,再执行sql,这里就不在赘述

四.配置zabbix

  1. 配置zabbix-server
    # vim /etc/zabbix/zabbix_server.conf

    可以修改server相关配置,例如:端口,日志,SSL,数据库,告警脚本路径等

    这里修改数据库配置和允许的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
    # 修改时区
    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.启动zabbix

  1. 启动zabbix-server和httpd
    # systemctl restart zabbix-server httpd
  2. 启动zabbix-agent
    # systemctl start zabbix-agent

六.访问zabbix界面

访问 http://192.168.152.140/zabbix/

七.其他

部署问题

  1. mysql zabbix 账号问题,启动zabbix-server时,出现了
      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

    解决: 修改zabbix账号

    ALTER USER 'zabbix'@'%' IDENTIFIED WITH mysql_native_password BY 'zabbix';
  2. 未关闭selinux,出现
    10947:20191029:145011.030 cannot start preprocessing service: Cannot bind socket to "/var/run/zabbix/zabbix_server_preprocessing.sock": [13] Permission denied.

    解决:临时关闭selinux

    # setenforce 0
