本篇继续搭建基于——Prometheus监控MySQL服务
一,部署环境准备
Prometheus服务器 | 192.168.100.12 |
Nginx+MySQL服务器 | 192.168.100.13 |
grafana 服务器 | 192.168.100.12 |
1,mysqld_exporter 组件下载
下载地址
https://github.com/prometheus/mysqld_exporter/releases/download/v0.13.0/mysqld_exporter-0.13.0.linux-amd64.tar.gz
2,mysql以及mysqld_exporter 组件安装
#解压安装包
tar zxf mysqld_exporter-0.13.0.linux-amd64.tar.gz
mv mysqld_exporter-0.13.0.linux-amd64 /usr/local/mysql_exporter
#安装mariadb
yum install mariadb\* -y
#启动数据库
systemctl start mariadb
systemctl enable mariadb
#查看端口
ss -natlp |grep 3306
#进入mysql (mariadb数据库不需要密码)
#在数据库里创建mysql账号用户收集数据
mysql -uroot
MariaDB [(none)]> grant select,replication client,process ON *.* to 'mysql_monitor'@'localhost' identified by '12345678';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)
3,在mysql_exporter中设置mysql配置信息
[root@localhost mysql_exporter]# pwd
/usr/local/mysql_exporter
[root@localhost mysql_exporter]# ls
LICENSE mysqld_exporter NOTICE
创建 .my.cnf 文件
[root@localhost mysql_exporter]# cat .my.cnf
[client]
user=mysql_monitor
password=12345678
4,启动mysql_exporter
[root@localhost mysql_exporter]# nohup ./mysqld_exporter --config.my-cnf=/usr/local/mysql_exporter/.my.cnf &
[1] 1649
[root@localhost mysql_exporter]# nohup: 忽略输入并把输出追加到"nohup.out"
5,查看端口9104是否起来
[root@localhost ~]# netstat -lnptu | grep 9104
tcp6 0 0 :::9104 :::* LISTEN 1649/./mysqld_expor
二,配置prometheus拉取mysql节点信息
1,在prometheus的server服务端进行修改
vim /usr/local/prometheus/prometheus.yml
- job_name: 'mysql'
static_configs:
- targets: ['192.168.100.13:9104']
2,重启prometheus服务
systemctl daemon-reload
systemctl restart prometheus.service
systemctl status prometheus.service

4,查看mysql数据页 http://192.168.100.13:9104/
Prometheus监控MySQL服务完成
