1. 准备

首先确保Redis主机能通过 127.0.0.1:6379 连接到redis。因为目前的zabbix agent 2有BUG，无法支持连接 127.0.0.1:6379 以外的其他URI。

# ./redis-cli 
127.0.0.1:6379> info
# Server
redis_version:5.0.13
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:6f9b8c6240f5565d
redis_mode:standalone
os:Linux 3.10.0-1062.el7.x86_64 x86_64

multiplexing_api:epoll

hz:10
configured_hz:10
lru_clock:3109087
executable:/usr/local/redis/src/./redis-server

...

2. 安装并配置agent

安装并配置zabbix agent 2，不是zabbix agent！

# yum list zabbix*agent*
已加载插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.tuna.tsinghua.edu.cn
 * extras: mirrors.tuna.tsinghua.edu.cn
 * updates: mirrors.tuna.tsinghua.edu.cn
已安装的软件包
zabbix-agent.x86_64                                                                 5.0.14-1.el7                                                                 @zabbix
zabbix-agent2.x86_64                                                                5.0.15-1.el7                                                                 @zabbix
可安装的软件包
zabbix-agent.x86_64                                                                 5.0.15-1.el7                                                                 zabbix

根据实际情况修改/etc/zabbix/zabbix_agent2.conf

...
Server=127.0.0.1,192.168.198.0/24
...
ServerActive=127.0.0.1,192.168.198.0/24
...
Hostname=192.168.198.144
...

启动zabbix agent 2

# systemctl status zabbix-agent2.service 
● zabbix-agent2.service - Zabbix Agent 2

在zabbix server侧使用zabbix_get进行测试

# zabbix_get -s 192.168.198.144 -k redis.ping

3. 配置主机

zabbix server侧进行主机配置
