1. 前期准备工作

2. 开始安装LAMP环境

  • 关闭防火墙
代码语言:javascript
复制
[root@zabbix54 ~]# systemctl disable --now firewalld
  • 关闭SELINUX
代码语言:javascript
复制
[root@zabbix54 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
  • 配置本地yum源
代码语言:javascript
复制
# 对如下repo进行重命名
[root@zabbix54 yum.repos.d]# mv CentOS-AppStream.repo CentOS-AppStream.repo.bak
[root@zabbix54 yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@zabbix54 yum.repos.d]# mv CentOS-Extras.repo CentOS-Extras.repo.bak
[root@zabbix54 yum.repos.d]# mv CentOS-Vault.repo CentOS-Vault.repo.bak

# 编辑CentOS-Media.repo
[root@zabbix54 yum.repos.d]# vi CentOS-Media.repo
[root@zabbix54 yum.repos.d]# cat CentOS-Media.repo 
# CentOS-Media.repo
#
#  This repo can be used with mounted DVD media, verify the mount point for
#  CentOS-8.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c8-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c8-media [command]

[root@zabbix54 zabbix-5.4.4]# chown -R apache:apache /var/www/html/

4. web初始化

  • 浏览器访问Zabbix服务器IP地址进入欢迎页面
  • 组件检查
  • 配置MySQL数据库密码
  • Zabbix服务器配置
  • GUI配置
  • 初始化信息汇总
  • 初始化安装,如果提示无法创建配置,点击页面上的链接下载配置文件上传到指定位置,并修改属组为apache:apache
  • 初始话完成,默认用户名:Admin,密码:zabbix
  • 进入仪表盘

5. ZABBIX SERVER IS NOT RENNING THE INFORMATION DISPLAYED MAY NOT BE CORRECT

Zabbix 5.4 启动后总是弹出ZABBIX SERVER IS NOT RENNING: THE INFORMATION DISPLAYED MAY NOT BE CORRECT的原因为SELINUX没有关闭,在前面的配置中我们已经关闭了SELINUX,因为没有重启,所以配置没有生效。

# 重启之后

6. Zabbix增加中文

  • 检查中文依赖包并进行中文依赖包安装

  • 监控项中文乱码处理

把C:\Windows\Fonts下的黑体(simhei.ttf)字体上传到Zabbix服务器,并复制到/var/www/html/assets/fonts目录(注意文件权限),查找下对应的assets/fonts即可,上传完成后修改/var/www/html/include/defines.inc.php,具体修改内容如下:复制define(‘ZBX_GRAPH_FONT_NAME’,’DejaVuSans’); // font file name这一行并注释掉修改字体名称为我们上传的字体define(‘ZBX_GRAPH_FONT_NAME’,’DejaVuSans’); // font file name
