[root@localhost zabbix]# hostnamectl 
   Static hostname: localhost.localdomain
         Icon name: computer-vm

安装包以及依赖

rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.7-1.el7.x86_64.rpm

yum install -y sysstat

编辑zabbix_agentd配置文件

[root@localhost zabbix]# cat /etc/zabbix/zabbix_agentd.conf |grep -v '^#' |grep -v "^$"
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
EnableRemoteCommands=1
Server=192.168.1.142
ServerActive=192.168.1.142
Hostname=jfgitlab
AllowRoot=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf

注：如果是zabbix_agentd与docker zabbix_server 部署在同一台服务器上，需要配置的Server以及ServerActive IP地址为docker容器内部IP，通过下面命令获取。

# docker exec -it zabbix_server ip addr

导入脚本

# mkdir /etc/zabbix/scripts
# mv disk_discovery.py disk_status.sh sysinfo.py /etc/zabbix/scripts/
# chmod +x /etc/zabbix/scripts/*
# echo 'UserParameter=sysinfo,/etc/zabbix/scripts/sysinfo.py' > /etc/zabbix/zabbix_agentd.d/userparameter_system.conf

# echo 'UserParameter=disk.discovery,/etc/zabbix/scripts/disk_discovery.py
UserParameter=disk.status[*],/etc/zabbix/scripts/disk_status.sh $1 $2' > /etc/zabbix/zabbix_agentd.d/userparameter_disk.conf

后台启动iostat

# nohup /usr/bin/iostat -dxkt 10  > /tmp/iostat_output 2>/dev/null &

# echo "nohup /usr/bin/iostat -dxkt 10  > /tmp/iostat_output 2>/dev/null &" >> /etc/rc.local
# chmod +x /etc/rc.d/rc.local

服务化

#!/bin/sh
#
# chkconfig: 2345 10 90
# description:  Starts and stops Zabbix Agent using chkconfig

SERVICE="Zabbix agent"
DAEMON=/usr/sbin/zabbix_agentd
PIDFILE=/var/run/zabbix/zabbix_agentd.pid

case $1 in
  'start')
    if [ -x ${DAEMON} ]
    then
      $DAEMON
      # Error checking here would be good...
      echo "${SERVICE} started."
    else
      echo "Can't find file ${DAEMON}."
      echo "${SERVICE} NOT started."
    fi
  ;;
  'stop')
    if [ -s ${PIDFILE} ]
    then
      if kill `cat ${PIDFILE}` >/dev/null 2>&1
      then
        echo "${SERVICE} terminated."
        rm -f ${PIDFILE}
      fi
    fi
  ;;
  'restart')
    $0 stop
    sleep 10
    $0 start
  ;;
  *)
    echo "Usage: $0 start|stop|restart"
    ;;
esac

启动服务

# chmod +x /etc/init.d/zabbix_agentd
# chkconfig --add zabbix_agentd
# /etc/init.d/zabbix_agentd start
