zabbix监控H3C设备

背景

常见的服务和主机已经使用Prometheus进行监控了，但是网络设备还未配置监控。使用基于SNMP对网络设备进行监控。

设备概览

主要类型为H3C的路由器和交换机。H3CS5560交换机路由器MER5200 er8300

步骤

配置网络设备开启telnet远程；

配置启用snmp协议；

zabbix界面添加主机进行监控；

snmp简介

SNMP simple network managerment protocol 分为三代，v3较为安全，需要配置用户名和密码及v3的加密密码。

组件

MySQL

配置MySQL，容器方式启动

MySQL采用8.0版本，配置文件，数据持久化

docker pull mysql:8.0mkdir -pv /data/mysql/{conf,data,logs}[root@localhost ~]# cat /data/mysql/conf/my.cnf
[mysqld]
default_authentication_plugin=mysql_native_password
character-set-server=utf8mb4
collation-server=utf8mb4_bin
default-storage-engine=INNODB# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M# Remove leading # to revert to previous value for default_authentication_plugin,
# this will increase compatibility with older clients. For background, see:
# https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_default_authentication_plugin
# default-authentication-plugin=mysql_native_password

使用yum repo中自带的是mariadb的MySQL5.x版本的客户端连接8.0版本数据库会报错

ERROR 2059 (HY000): Authentication plugin ‘sha256_password’ cannot be loaded: /usr/lib64/mysql/plugin/sha256_password.so: cannot open shared object file: No such file or directory

解决：安装MySQL community的客户端

wget https://repo.mysql.com//mysql80-community-release-el7-3.noarch.rpmyum install mysql-community-client --nogpgcheckmysql -uroot -h127.0.0.1 -pzabbix@123MySQL [(none)]> create database zabbix character set utf8 collate utf8_bin;
MySQL [(none)]> create user zabbix@'%' identified by 'xxxxxxx';
MySQL [(none)]> grant all privileges on zabbix.* to zabbix@'%';
MySQL [(none)]> set global log_bin_trust_function_creators = 1;
MySQL [(none)]> flush privileges;

zabbix配置

检查所有的组件依赖都是ok
