MySQL监控利器-PMM

本篇文章来简要介绍一下MySQL监控利器-PMM的部署过程。

环境：

主机名	IP	功能	系统	数据库版本
pmmclient	192.168.91.34	PMM-client	RHEL7.4
pmmserver	192.168.91.35	PMM-server	RHEL7.4	MySQL5.7.26

 部署：

server端：

[root@pmmserver ~]#yum -y install docker

[root@pmmserver ~]# systemctl start docker

[root@pmmserver ~]# systemctl enable docker

[root@pmmserver ~]# docker pull pmm-server

[root@pmmserver ~]# docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
docker.io/percona/pmm-server   latest              cc8e60d34a15        7 weeks ago         1.2 GB

[root@pmmserver ~]# docker create -v /u02/monitor/prometheus/data -v /u02/monitor/consul-data -v /u02/monitor/lib/mysql -v /u02/monitor/lib/grafana --name pmm-data docker.io/percona/pmm-server:latest

[root@pmmserver ~]# docker run -d -p 80:80 -p 3000:3000 -p 13306:3306 --volumes-from pmm-data --name pmm-server --restart always docker.io/percona/pmm-server:latest

[root@pmmserver ~]# docker ps
CONTAINER ID        IMAGE                                 COMMAND                CREATED             STATUS              PORTS                                                                          NAMES
569aaaca23a1        docker.io/percona/pmm-server:latest   "/opt/entrypoint.sh"   21 hours ago        Up 21 hours         0.0.0.0:80->80/tcp, 0.0.0.0:3000->3000/tcp, 443/tcp, 0.0.0.0:13306->3306/tcp   pmm-server

访问server的IP地址就可以访问了（默认用户名密码：admin）

client端（被监控的服务器上）

[root@pmmclient soft]# ll pmm-client-1.16.0-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 23057592 Dec 18 10:44 pmm-client-1.16.0-1.el6.x86_64.rpm

[root@pmmclient soft]# rpm -ivh pmm-client-1.16.0-1.el6.x86_64.rpm

[root@pmmclient soft]# pmm-admin --version
1.16.0

[root@pmmclient soft]# pmm-admin config --server 192.168.91.35
OK, PMM server is alive.

PMM Server      | 192.168.91.35
Client Name     | master
Client Address  | 192.168.91.34

pmm客户端监控MySQL到pmm服务器

[root@pmmclient soft]# mysql -uroot -pkavl7kAkkle!   建立监控用户

mysql> create user 'pmm_monitor'@'192.168.91.%' identified by 'kavl7kAkkle!';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all privileges on *.* to 'pmm_monitor'@'192.168.91.%';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

[root@pmmclient soft]# pmm-admin config --server 192.168.91.35
OK, PMM server is alive.

PMM Server      | 192.168.91.35
Client Name     | master
Client Address  | 192.168.91.34

[root@pmmclient soft]# pmm-admin add mysql --user pmm_monitor --password kavl7kAkkle! --host 192.168.91.34 --port 3306
[linux:metrics] OK, already monitoring this system.
[mysql:metrics] OK, now monitoring MySQL metrics using DSN pmm_monitor:***@tcp(192.168.91.34:3306)
[mysql:queries] OK, now monitoring MySQL queries from slowlog using DSN pmm_monitor:***@tcp(192.168.91.34:3306)
