zabbix-agent安装

环境:
OS:Centos 7
zabbix:4.0.5

1.将基础镜像修改为阿里云的
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all

2.生成zabbix yum文件
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm

3.安装zabbix-agent
yum install -y zabbix-agent

4.启动
systemctl start zabbix-agent
systemctl status zabbix-agent

5.修改配置文件
/etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=1

DebugLevel=3
SourceIP=192.168.1.135
EnableRemoteCommands=1
LogRemoteCommands=1

Server=192.168.1.136
ListenPort=10050

ListenIP=192.168.1.135
StartAgents=3

ServerActive=192.168.1.136

Hostname=host135
HostnameItem=system.hostname

RefreshActiveChecks=120
BufferSend=20

BufferSize=100
MaxLinesPerSecond=20
Timeout=3
AllowRoot=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf
UnsafeUserParameters=1

红色标注为关键参数

6.重启
systemctl restart zabbix-agent

7.zabbix服务端创建自动发现(好像不管用)

配置自动发现的动作，注意状态必须为“启用”

8.也可以手工添加添加
