安装 Zabbix 服务器
从官方仓库添加 Zabbix 6.0 LTS 仓库并安装核心组件：
sudo zypper addrepo https://repo.zabbix.com/zabbix/6.0/sles/15/sp4/x86_64/ zabbix
sudo zypper refresh
sudo zypper install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-agent
配置 MySQL 数据库
创建专用数据库并导入初始架构：
mysql -u root -p -e "CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin"
mysql -u root -p -e "CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'secure_password'"
mysql -u root -p -e "GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost'"
zcat /usr/share/doc/packages/zabbix-sql-scripts/mysql/server.sql.gz | mysql -u zabbix -p zabbix
优化 Zabbix 服务器配置
编辑 /etc/zabbix/zabbix_server.conf 关键参数：
DBPassword=secure_password
StartPollers=20
StartPollersUnreachable=10
StartTrappers=15
StartPingers=5
CacheSize=512M
HistoryCacheSize=256M
TrendCacheSize=256M
ValueCacheSize=512M
Timeout=30
调整 PHP 参数
修改 /etc/php7/apache2/php.ini 以适应 Web 界面：
memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 16M
max_execution_time = 300
max_input_time = 300
配置 Apache 虚拟主机
确保 /etc/apache2/vhosts.d/zabbix.conf 包含：
<VirtualHost *:80>
DocumentRoot /usr/share/zabbix
<Directory "/usr/share/zabbix">
Require all granted
AllowOverride None
</Directory>
</VirtualHost>
性能调优建议
对于监控超过 1000 台设备的环境：
- 将 StartPollers 增加到 50-100
- 配置 Proxy 架构分担服务器负载
- 启用 Housekeeping 定期清理旧数据
- 对历史数据表进行分区处理
安全加固措施
实施以下安全策略：
sudo firewall-cmd –permanent –add-port=10050/tcp
sudo firewall-cmd –permanent –add-port=10051/tcp
sudo firewall-cmd –reload
sudo chown -R zabbix:zabbix /etc/zabbix/web
sudo setsebool -P httpd_can_network_connect_db 1
监控项优化技巧
对于高频监控项：
- 调整 UpdateInterval 避免过密采集
- 使用 Dependent items 减少重复查询
- 对数值型数据启用 Delta 计算模式
- 配置适当的 Trigger 阈值避免误报
告警通知配置
在管理界面配置：
定期维护任务
建议设置以下 cron 作业：
0 3 * * * /usr/bin/zabbix_server -R housekeeper_execute
0 4 * * 0 /usr/bin/mysqlcheck -o zabbix
以上配置需根据实际硬件资源（CPU/内存）和监控规模进行调整，生产环境建议先进行性能测试。
