Zabbix-agent2 安装部署

zabbix-agent2是zabbix的客户端，go语言开发。

默认使用10050端口，

环境准备

准备两台虚拟机，关闭防火墙，设置主机名

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@localhost ~]# vi /etc/selinux/config

[root@localhost ~]# setenforce 0

[root@localhost ~]# getenforce

Permissive

[root@localhost ~]# hostnamectl set-hostname zabbix-agent2

[root@localhost ~]# bash

[root@zabbix-agent2 ~]#

配置时间同步

[root@zabbix-agent2 ~]# yum install -y ntpdate

[root@zabbix-agent2 ~]# ntpdate -u ntp.aliyun.com

8 Jul 18:16:17 ntpdate[3228]: step time server 203.107.6.88 offset 1447561.766187 sec

[root@zabbix-agent2 ~]# date

[root@zabbix-agent2 ~]#

安装zabbix-agent2

# 配置yum源 、安装 
# 如果不想配置yum源，可以在server节点下载一个agent  rpm包，使用ansible批量部署

# 两个节点同样的操作

[root@zabbix-agent2 ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

修改配置文件

## 默认配置文件为这样

[root@zabbix-agent2 ~]# grep -Ev '^#|^#39; /etc/zabbix/zabbix_agent2.conf

PidFile=/var/run/zabbix/zabbix_agent2.pid

LogFile=/var/log/zabbix/zabbix_agent2.log

LogFileSize=0

Server=127.0.0.1

ServerActive=127.0.0.1

Hostname=Zabbix server

Include=/etc/zabbix/zabbix_agent2.d/*.conf

ControlSocket=/tmp/agent.sock

# 修改为

[root@zabbix-agent2 ~]# grep -Ev '^#|^#39; /etc/zabbix/zabbix_agent2.conf

PidFile=/var/run/zabbix/zabbix_agent2.pid

LogFile=/var/log/zabbix/zabbix_agent2.log

LogFileSize=0

Server=10.30.59.242  # zabbix_server 地址

ServerActive=10.30.59.242  

Hostname=Zabbix_agent241  # agent节点名字，最好配置不一样的做区分

Include=/etc/zabbix/zabbix_agent2.d/*.conf

ControlSocket=/tmp/agent.sock

# 需要修改主机名、server serveractive
# 重启
[root@zabbix-agent2 ~]# systemctl restart zabbix-agent2

验证

在server端安装zabbix-get ，使用命令验证。

[root@zabbix-server ~]# yum install -y zabbix-get

[root@zabbix-server ~]# zabbix_get -s '10.30.59.241' -p 10050 -k 'agent.ping'

1

# 获取agent节点的主机名

[root@zabbix-server ~]# zabbix_get -s '10.30.59.241' -p 10050 -k 'system.hostname'

zabbix-agent2

[root@zabbix-server ~]# zabbix_get -s '10.30.59.243' -p 10050 -k 'system.hostname'

zabbix-agent243

这样就代表agent安装没有问题了，就可以使用web界面添加单个agent了 ， 后面实现自动发现及自动注册就不需要一个一个的添加了。
