运维监控之Prometheus入门安装篇

yum install go

[root@iZtd8edkkjhg2sxz5wck0rZ ~]#  go version
go version go1.11.4 linux/amd64

wget https://github.com/prometheus/prometheus/releases/download/v2.7.1/prometheus-2.7.1.linux-amd64.tar.gz

tar -zxvf prometheus-2.7.1.linux-amd64.tar.gz

mv prometheus-2.7.1.linux-amd64 prometheus

chattr -i /etc/group;chattr -i /etc/gshadow;chattr -i /etc/passwd;chattr -i /etc/shadow
groupadd prometheus
useradd -g prometheus prometheus
chattr +i /etc/group;chattr +i /etc/gshadow;chattr +i /etc/passwd;chattr +i /etc/shadow

chown -R prometheus:prometheus /home/prometheus

chmod 744 /etc/init.d/prometheus

在启动的脚本添加如下：
--web.listen-address=:$appPort（修改的端口号）

service prometheus start|stop|restart|status

#!/bin/sh
# chkconfig:35 90 3
