本文档一共需要三个包

经过测试需要使用8以上的版本，要不然模板会有问题，数据可能不显示

 时间校准

必须进行时间校准，否则后面会出问题

[root@localhost prometheus]# yum install -y ntp

[root@localhost prometheus]# systemctl start ntpd

[root@localhost prometheus]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

[root@localhost prometheus]# ntpdate pool.ntp.org
20 Mar 13:28:42 ntpdate[11438]: the NTP socket is in use, exiting

[root@localhost prometheus]# systemctl restart ntpd

[root@localhost prometheus]# date
Wed Mar 20 13:28:55 CST 2024

 

 

安装部署node_exporter

解压文件

[root@localhost ~]# ll

 关闭防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

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

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

进行安装

[root@localhost ~]# mv node_exporter /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
bin  etc  games  include  lib  lib64  libexec  node_exporter  sbin  share  src
[root@localhost local]# cd node_exporter/
[root@localhost node_exporter]# ls

创建服务

不能直接运行程序，默认是运行在前台，所以需要一个服务来开启

2cbaff232fbf1d88768d7f4cbc2b437e.png

[root@localhost node_exporter]# vim /etc/systemd/system/node_exporter.service
[root@localhost node_exporter]# cat /etc/systemd/system/node_exporter.service 
[Unit]

After=network.target

[Service]
Restart=on-failure
ExecStart=/usr/local/node_exporter/node_exporter

[Install]

开启服务并设置开机自启
