# 此处以CentOS 7为例
# 下载完成后上传到服务器并解压,或者直接wget下载
wget https://github.com/prometheus/prometheus/releases/download/v2.21.0/prometheus-2.21.0.linux-amd64.tar.gz
tar -zxvf prometheus-2.21.0.linux-amd64.tar.gz
# 由于解压后的文件夹名过长，重命名文件夹
mv prometheus-2.21.0.linux-amd64 prometheus
# 根据实际路径修改路径，并指定需要监听的端口，这样，简单的Prometheus服务端就搭建好了
nohup /root/prometheus/prometheus --web.listen-address=0.0.0.0:9090 --config.file=/root/prometheus/prometheus.yml --web.enable-lifecycle --storage.tsdb.path=/root/prometheus/data --storage.tsdb.retention.time=15d &
# 不要忘记防火墙放行端口，--permanent参数为永久生效，不加此参数重启失效
firewall-cmd --zone=public --add-port=9090/tcp --permanent
# 或者直接停用防火墙（不推荐）
systemctl stop firewalld
systemctl disable firewalld
