一、PMM-SERVER1. 安装dockeryum install -y docker-io2. 拉取pmm-server镜像docker pull percona/pmm-server:lates
一、PMM-SERVER
1. 安装docker
yum install -y docker-io2. 拉取pmm-server镜像
docker pull percona/pmm-server:latest3. 创建持久化容器
docker create / -v /opt/prometheus/data / -v /opt/consul-data / -v /var/lib/mysql / -v /var/lib/grafana / --name pmm-data / percona/pmm-server:latest /bin/true4. 启动pmm-server
docker run -d / -p 8888:80 / #将docker的80端口映射到宿主机的8888端口 --volumes-from pmm-data / --name pmm-server / --restart always / percona/pmm-server:latest查看运行状态
[root@localhost ~]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES983cb32aa7ca percona/pmm-server:latest "/opt/entrypoint.sh" 4 days ago Up 4 days 443/tcp, 0.0.0.0:8888->80/tcp pmm-server 670aaeb497cf percona/pmm-server:latest "/bin/true" 4 days ago pmm-data 5. 关闭匿名登陆,并调整时区
[root@localhost docker]# docker exec -it pmm-server /bin/bash #进入docker容器[root@983cb32aa7ca opt]# vi /etc/grafana/grafana.ini#################################### Anonymous Auth ##########################[auth.anonymous]# enable anonymous access#enabled = True[root@983cb32aa7ca opt]# cat /etc/localtime TZif2UTCTZif2UTCUTC0[root@983cb32aa7ca opt]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime cp: overwrite '/etc/localtime'? y6. 登陆dashboard
浏览器中输入: xx.xx.xx.xx:8888
二、PMM-CLIENT
1. 在需要监控的机器上安装pmm-client
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm #配置percona源yum install pmm-client #安装pmm-client2. 配置pmm-server地址
--server 后接的是pmm-server的地址和端口
-c 后边接的是配置文件，默认配置文件为/usr/local/percona/pmm-client/pmm.yml
pmm-admin config --server xx.xx.xx.xx:8888 -c /usr/local/percona/pmm-client/pmm.yml 以下是配置文件的内容
cat /usr/local/percona/pmm-client/pmm.ymlserver_address: xx.xx.xx.xx:8888client_address: xx.xx.xx.xxbind_address: xx.xx.xx.xxclient_name: monitor-node13. 添加linux系统监控
pmm-admin add linux:metrics 4. 添加MySQL监控
在MySQL实例中创建监控用户：
GRANT SELECT, PROCESS, SUPER, REPLICATION CLIENT, RELOAD ON *.* TO 'pmm'@'127.0.0.1' IDENTIFIED BY 'pmm' WITH MAX_USER_CONNECTIONS 10;GRANT SELECT, UPDATE, DELETE, DROP ON performance_schema.* TO 'pmm'@'127.0.0.1';添加MySQL监控
pmm-admin add mysql --host 127.0.0.1 --user pmm --password pmm --port 3306 instance3306 ##此命令是监控MySQL实例状态以及慢查询分析，如果不想监控慢日志使用mysql:metrics即可三、遇到的问题
1. purge报错
某台机器下线，需要清理pmm-server中关于这台机器的数据，执行purge命令后报错

2. _PMM System Summary面板无法显示MySQL信息汇总
报错如下：
Server summary:mysql summary - Exit Status 1解决办法：将MySQL相关命令软连接到/usr/bin/
ln -s /usr/local/mysql/bin/* /usr/bin/参考地址：https://www.percona.com/forums/questions-discussions/percona-monitoring-and-management/47268-server-summary-mysql-summary-exit-status-1
