zabbix 監控

• NGINX
• 採用：https://github.com/vicendominguez/nginx-zabbix-template
• 注意點：
1. 採用Installation in the Zabbix Server，直接在zabbix server上下指令
2. 可能有必要自行指定URL的位置，原先樣本內採用 HOST.CONN，這部分如果與現況不符合，就得將在 TEMPLATE 的 ITEM 的 HOST.CONN換成 MACRO 來指定，且同時也需要在HOST內加入該 MACRO 的URL值
• MYSQL
• 採用zabbix官方的template
• 注意點：
• 在Mysql的DB端，需要加一個使用者提供mysql取用狀態用
• 並在Mysql的OS上要設定一個 .my.cnf，提供給zabbix_agent回應server的呼叫

• # Zabbix Agent
  [mysql]
  host=localhost
  user=zabbix
  password=password
  #socket=/var/lib/mysql/mysqld.sock
  socket=/var/run/mysqld/mysqld.sock
  [mysqladmin]
  host=localhost
  user=zabbix
  password=password
  #socket=/var/lib/mysql/mysqld.sock
  socket=/var/run/mysqld/mysqld.sock
  

• 修改 /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf 中，HOME=/etc/zabbix，這個部分，要符合前項.my.cnf的位置
