CentOS7 二进制安装 zabbix_agent 5.0
环境准备
关闭防火墙和selinux
#关闭selinux
[root@centos7 ~]#sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
#关闭防火墙
[root@centos7 ~]#systemctl disable --now firewalld
#重启生效
[root@centos7 ~]#reboot
1. 安装zabbix rpm源
[root@centos7 ~]#rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
[root@centos7 ~]#sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
[root@centos7 ~]#yum clean all
2. 安装zabbix agent
[root@centos7 ~]#yum install -y zabbix-agent
#编辑配置文件 /etc/yum.repos.d/zabbix.repo
[root@centos7 ~]#vim /etc/yum.repos.d/zabbix.repo
[zabbix-frontend]
...
enabled=1
...
3. 修改zabbix agent配置文件
[root@centos7 ~]#vim /etc/zabbix/zabbix_agentd.conf
Server=10.0.0.17 #指向当前zabbix server
ListenPort=10050 #监听端口
ListenIP=0.0.0.0 #监听IP
StartAgents=5 #被动状态时，默认启动的实例（进程数），0为不监听任何端口
Hostname=10.0.0.7 #区分大小写且在zabbix server唯一的值
[root@centos7 ~]#grep "^[a-Z]" /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=10.0.0.17
ListenPort=10050
ListenIP=0.0.0.0
StartAgents=5
ServerActive=127.0.0.1
Hostname=10.0.0.7
Include=/etc/zabbix/zabbix_agentd.d/*.conf
4 启动Zabbix agent进程
#启动Zabbix agent进程，并设置开机自启
[root@centos7 ~]#systemctl restart zabbix-agent.service
[root@centos7 ~]#systemctl enable zabbix-agent.service
[root@centos7 ~]#systemctl status zabbix-agent.service

5. zabbix web界面添加被监控主机
点击【配置-主机-创建主机】
#【ZBX】绿色，表示主机可用，监控指标检查已成功，zabbix server对zabbix agent有权限进行数据采集并且当前通信正常
经过一段时间的数据采集后，就可以看到数据了
6. 在zabbix server主机上安装Zabbix get命令行工具
#Zabbix get是一个命令行应用，它可以用于与Zabbix agent进行通信，并从Zabbix agent那里获取所需的信息。
该应用通常被用于Zabbix agent故障排错。
[root@centos7 ~]#yum list all |grep zabbix-get
zabbix-get.x86_64 5.0.24-1.el7 zabbix
[root@centos7 ~]#yum -y install zabbix-get.x86_64
[root@centos7 ~]#/bin/zabbix_get -s 10.0.0.7 -p 10050 -k "agent.ping"
