前言
本文详细介绍了Zabbix6通过ODBC方式监控Oracle 19C的过程
1.19C客户端安装
✨ 1.1 19C客户端下载
#创建zabbix目录,进入zabbix目录 [root@jeames ~]# mkdir -p /zabbix [root@jeames ~]# cd /zabbix 以下为官方下载地址 https://download.oracle.com/otn_software/linux/instantclient/199000/oracle-instantclient19.9-basic-19.9.0.0.0-1.x86_64.rpm https://download.oracle.com/otn_software/linux/instantclient/199000/oracle-instantclient19.9-sqlplus-19.9.0.0.0-1.x86_64.rpm https://download.oracle.com/otn_software/linux/instantclient/199000/oracle-instantclient19.9-devel-19.9.0.0.0-1.x86_64.rpm https://download.oracle.com/otn_software/linux/instantclient/199000/oracle-instantclient19.9-odbc-19.9.0.0.0-1.x86_64.rpm
✨ 1.2 客户端安装
[root@jeames zabbix]# yum localinstall oracle-instantclient19.9-*
注意:实现配置好本地yum,请参考以下博客
Linux配置本地yum源,高效便捷
https://jeames.blog.csdn.net/article/details/120557997
#oracle-instantclient的安装位置如下 [root@jeames zabbix]# find / -name client64 /usr/lib/oracle/19.9/client64 /usr/share/oracle/19.9/client64 /usr/include/oracle/19.9/client64
2.数据库相关操作
✨ 2.1 确认监听状态
## 保证好数据库监听和实例是运行状态 [root@jeames ~]# su - oracle [oracle@jeames ~]$ lsnrctl status [oracle@jeames ~]$ lsnrctl start
✨ 2.2 实例名及服务名
SQL> show parameter name
SQL> show pdbs
✨ 2.3 Zabbix用户创建
--开PDB库 SQL> alter pluggable database PDB2 open; SQL> select name,cdb from v$database; --CDB切到PDB SQL> alter session set container = PDB2; SQL> create user zabbix identified by zabbix; SQL> grant dba to zabbix;
3.客户端配置
注意:以下均在Zabbix Server做操作
✨ 3.1 配置环境变量
vi /etc/profile cat >> /etc/profile << "EOF" export ORACLE_HOME=/usr/lib/oracle/19.9/client64 export PATH=$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib64:/usr/lib:$ORACLE_HOME/bin export TNS_ADMIN=$ORACLE_HOME/network/admin EOF #环境变量生效 [root@jeames ~]# source /etc/profile ## 驱动 chmod +x /usr/lib/oracle/19.9/client64/lib/libsqora.so.19.1
✨ 3.2 添加Oracle驱动
-- 配置odbcinst.ini文件信息: [root@jeames ~]# vi /etc/odbcinst.ini #添加如下内容 [Oracle] Description = Oracle ODBC driver for Oracle 19c Driver = /usr/lib/oracle/19.9/client64/lib/libsqora.so.19.1 --配置odbc.ini文件 [root@jeames ~]# odbcinst -j unixODBC 2.3.1 DRIVERS............: /etc/odbcinst.ini SYSTEM DATA SOURCES: /etc/odbc.ini FILE DATA SOURCES..: /etc/ODBCDataSources USER DATA SOURCES..: /root/.odbc.ini SQLULEN Size.......: 8 SQLLEN Size........: 8 SQLSETPOSIROW Size.: 8 [root@jeames ~]# rm -rf /root/.odbc.ini cat >> /etc/odbc.ini << "EOF" [ora19c] Driver = Oracle ServerName = 192.168.1.32:1521/pdb2 UserID = zabbix Password = zabbix Port= 1521 EOF
✨ 3.3 验证是否配置成功
[root@jeames ~]# isql -v ora19c +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+ 注:sqlplus 用户名/密码@IP/oracle数据库服务名 #如sqlplus zbbix/zbbix@IP:1521/cdb1
4.Zabbix监控
1.模板另存 配置-模板-Oracle by ODB-全克隆,此处另存为Oracle by ODBC 19C,点击应用户 2.配置主机 1)配置-主机-创建主机-选择模板Oracle by ODBC 19C 2)宏的地方做如下创建 {$ORACLE.DRIVER} Oracle {$ORACLE.PASSWORD} zabbix {$ORACLE.PORT} 1521 {$ORACLE.SERVICE} pdb2 {$ORACLE.USER} zabbix {$HOST.CONN} 192.168.1.32
