prometheus监控

一、用二进制安装

1、安装Prometheus

打开官方网址：https://prometheus.io/download/

wget https://github.com/prometheus/prometheus/releases/download/v2.45.4/prometheus-2.45.4.linux-amd64.tar.gz

下载完成后解压一下安装包

tar vxf prometheus-2.45.4.linux-amd64.tar.gz

解压完成ls查看一下，并移动到/opt下改名为prometheus

[root@localhost ~]# ls -l
total 90424
-rw-r--r--  1 root root          0 Apr 19 05:51 ?
-rw-------. 1 root root       1244 Apr 15 05:34 anaconda-ks.cfg
drwxr-xr-x. 2 root root         24 Apr 19 06:12 conf
-rw-r--r--  1 root root        348 Apr 19 07:22 docker-compose.yml
drwxr-xr-x. 2 root root         57 Apr 19 09:06 html
drwxr-xr-x  4 1001 docker      132 Mar 18 07:23 prometheus-2.45.4.linux-amd64
-rw-r--r--  1 root root   92584268 Mar 18 07:26 prometheus-2.45.4.linux-amd64.tar.gz
[root@localhost ~]# mv prometheus-2.45.4.linux-amd64 /opt/prometheus

完成后，创建一个专门的prometheus用户，并更改prometheus用户的文件权限：

[root@localhost ~]# useradd -M -s /usr/sbin/nologin prometheus
id[root@localhost ~]# id prometheus
uid=1000(prometheus) gid=1000(prometheus) groups=1000(prometheus)
[root@localhost ~]# chown prometheus:prometheus -R /opt/prometheus

下一步创建systemd服务

[root@localhost ~]# cat > /etc/systemd/system/prometheus.service << "EOF"
[Unit]

Documentation=https://prometheus.io/docs/introduction/overview/
After=network-online.target

  --storage.tsdb.retention.time=60d \
  --web.enable-lifecycle

[Install]
WantedBy=multi-user.target
EOF
[root@localhost ~]# ls -l /etc/systemd/system/prometheus.service
