5 ## Step 1 - Create a new User and Download Prometheus
6
7 Create a new user
8 ```
9 useradd -m -s /bin/bash prometheus
10 ```
11 Become prometheus user and download the software
12 ```
13 su - prometheus
14 wget https://github.com/prometheus/prometheus/releases/download/v2.17.1/prometheus-2.17.1.linux-amd64.tar.gz
15 ```
16
17 Extract the tarball and rename the directory
18 ```
19 tar -xzvf prometheus-2.17.1.linux-amd64.tar.gz
20 mv -v prometheus-2.17.1.linux-amd64 prometheus
21 ```
22
23 ## Step 2 - Configure Prometheus As a Systemd Service
24 ```

51 Start and enable Prometheus
52 ```
53 systemctl start prometheus
54 systemctl enable prometheus
55 ```
56 Check that everything is fine
57 ```
58 systemctl status prometheus
59 netstat -plntu
60 ```
61
62 # Step 3 - Configure Firewalld
63
64 Open port 9090 for the Prometheus access using firewall-cmd commands below.
65 ```
66 firewall-cmd --add-port=9090/tcp --permanent
67 firewall-cmd --reload
68 ```
69 # Step 4 - Install and Configure node_exporter
70
71 Download node_exporter
72 ```
73 su - prometheus
74 wget https://github.com/prometheus/node_exporter/releases/download/v1.0.0-rc.0/node_exporter-1.0.0-rc.0.linux-amd64.tar.gz
75 ```
76 extract node exporter and rename the directory
77 ```
78 tar -xzvf /vagrant/node_exporter-1.0.0-rc.0.linux-amd64.tar.gz
79 mv node_exporter-1.0.0-rc.0.linux-amd64/ node_exporter
80 ```
81
82 Create a new service for node_exporter
83 ```
84 cd /etc/systemd/system/

97 EOF
98 ```
99 Reload systemd
100 ```
101 systemctl daemon-reload

103 Enable and start the service
104 ```
105 systemctl start node_exporter
106 systemctl enable node_exporter
107 ```
108 Check that everything is fine
109 ```
110 netstat -plntu
111 ```
112
113 # Step 5 - Add node_exporter to the Prometheus Server
114 Login to the prometheus user.
115 ```
116 su - prometheus
117 ```
118 Goto the 'prometheus' directory and edit the configuration file 'prometheus.yml'.
119 ```
120 cd prometheus/
121 vim prometheus.yml
122 ```
123 Under the 'scrape_config' line, add new job_name node_exporter by copy-pasting the configuration below.
124 ```
125 - job_name: 'node_exporter'
126 static_configs:
127 - targets: ['localhost:9100']
128 ```
129 Restart the prometheus service
130 ```
131 systemctl restart prometheus
