Prometheus PushGetway部署

准备工作

1、创建用户和配置环境参数

(1)、创建用户和创建所需目录

[root@centos ~]# groupadd prometheus
[root@centos ~]# useradd -d /home/prometheus -g prometheus -m prometheus
[root@centos ~]# chmod 755 /home/prometheus
[root@centos ~]# mkdir -p /home/prometheus/software
[root@centos ~]# mkdir -p /home/prometheus/yunwei
[root@centos ~]# chown -R prometheus:prometheus /home/prometheus
[root@centos ~]# mkdir -p /data/prometheus
[root@centos ~]# chown -R prometheus:prometheus /data/prometheus

(2)、下载

https://github.com/prometheus/pushgateway/releases/download/v1.5.1/pushgateway-1.5.1.linux-amd64.tar.gz

部署方案

1、部署

(1)、关闭防火墙

[root@centos ~]# systemctl stop firewalld
[root@centos ~]# 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@centos ~]# setenforce 0
[root@centos ~]# getenforce 
Permissive
[root@centos ~]# vi /etc/sysconfig/selinux 

# 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 values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

(2)、解压安装包并备份配置文件

[prometheus@centos ~]$ tar -zxf $HOME/software/pushgateway-1.5.1.linux-amd64.tar.gz -C $HOME
[prometheus@centos ~]$ mv pushgateway-1.5.1.linux-amd64 pushgateway-1.5.1

(3)、创建日志路径

[prometheus@centos ~]$ mkdir /data/prometheus/pushgateway-1.5.1/logs -p
[prometheus@centos ~]$ touch /data/prometheus/pushgateway-1.5.1/logs/pushgateway-1.5.1.log

2、添加配置

(1)、pushgetway相关参数

[prometheus@centos ~]$ $HOME/pushgateway-1.5.1/pushgateway --help
usage: pushgateway []

The Pushgateway

Flags:
  -h, --help                     Show context-sensitive help (also try --help-long and --help-man).
      --web.systemd-socket       Use systemd socket activation listeners instead of port listeners (Linux only).
      --web.listen-address=:9091 ...  
                                 Addresses on which to expose metrics and web interface. Repeatable for multiple addresses.
      --web.config.file=""       [EXPERIMENTAL] Path to configuration file that can enable TLS or authentication.
      --web.telemetry-path="/metrics"  
                                 Path under which to expose metrics.
      --web.external-url=        The URL under which the Pushgateway is externally reachable.
      --web.route-prefix=""      Prefix for the internal routes of web endpoints. Defaults to the path of --web.external-url.
      --web.enable-lifecycle     Enable shutdown via HTTP request.
      --web.enable-admin-api     Enable API endpoints for admin control actions.
      --persistence.file=""      File to persist metrics. If empty, metrics are only kept in memory.
      --persistence.interval=5m  The minimum interval at which to write out the persistence file.
      --push.disable-consistency-check  
                                 Do not check consistency of pushed metrics. DANGEROUS.
      --log.level=info           Only log messages with the given severity or above. One of: [debug, info, warn, error]
      --log.format=logfmt        Output format of log messages. One of: [logfmt, json]
      --version                  Show application version.

(2)、配置prometheus配置

[prometheus@centos ~]$ vi $HOME/prometheus/prometheus.yml
# 新增
- job_name: "pushgetway"
  static_config:
    - targets: ["192.168.19.149:9091"]
    
# 记得改完配置重启prometheus服务

3、启停服务与创建脚本

(1)、启动脚本配置

[prometheus@centos ~]$ vi yunwei/pushgateway-1.5.1_start.sh
#!/bin/bash
#
cd $HOME/pushgateway-1.5.1
./pushgateway --web.listen-address=:9091 >> /data/prometheus/pushgateway-1.5.1/logs/pushgateway-1.5.1.log &

(2)、停止脚本配置

[prometheus@centos ~]$ vi yunwei/pushgateway-1.5.1_stop.sh
#!/bin/bash
#
pgw_id=`ps -ef|grep pushgateway|grep -v grep|awk '{print $2}'`
kill -9 $pgw_id
