1. PMM介绍
Percona Monitoring and Management (PMM)是一个针对MySQL、PostgreSQL和MongoDB的开源数据库监控、管理和可视化解决方案的工具，分为服务端和客户端。
- PMM有多种安装方式，我以docker方式安装
- PMM客户端安装在你需要监控的主机里
2. 安装PMM服务端
官方文档安装
Docker - Percona Monitoring and Management
2.1 安装docker
2.1.1 下载docker
https://download.docker.com/linux/static/stable/x86_64/
2.1.2 上传docker包
手动下载tar包后上传到Linux主机， 并将解压出来的docker文件内容移动到 /usr/bin/ 目录下
[root@localhost soft]# tar -zxvf docker-20.10.6.tgz
[root@localhost soft]# cp docker/* /usr/bin2.1.3 启动守护进程
[root@localhost soft]# dockerd &2.1.4 查看docker状态
查看是否成功，看到下面结果说明docker启动成功
[root@localhost soft]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2.2 安装PMM
2.2.1 下载镜像
PMM服务端docker镜像下载地址
https://www.percona.com/downloads
2.2.2 load镜像
也可以不下载镜像，直接pull镜像，会从网上下载（docker pull percona/pmm-server:2.41.1）
[root@localhost soft]# docker load < pmm-server-2.41.1.docker
c83f386e1dda: Loading layer [==================================================>] 114.2MB/114.2MB

percona/pmm-server 2.41.1 a71c917d72f2 2 months ago 2.34GB2.2.4 创建容器
[root@localhost bin]# docker create --volume /srv \
> --name pmm-data percona/pmm-server:2.41.1 /bin/true2.2.5 运行镜像
[root@localhost bin]# docker run --detach --restart always \
> --publish 443:443 \
> --volumes-from pmm-data --name pmm-server \
> percona/pmm-server:2.41.12.2.6 验证PMM服务器
运行PMM Server之后，可以使用运行容器的主机的IP地址访问PMM Web界面，服务器ip:443 即可打开服务端webui，访问默认用户密码：admin / admin，第一次进去提示修改密码
2.2.7 删除PMM服务
#停止pmm-server容器
docker stop pmm-server
#删除容器
docker rm pmm-server pmm-data
#删除镜像
docker rmi $(docker images | grep "percona/pmm-server" | awk {'print $3'})3. 安装PMM客户端
官方文档安装客户端
Set up PMM Client - Percona Monitoring and Management
3.1 下载客户端
我下载的是二进制文件，下面是下载地址，选择版本号和linux generic
https://www.percona.com/downloads
3.2 上传解压
[root@localhost soft]# tar -zxvf pmm2-client-2.41.1.tar.gz3.3 配置环境变量
[root@localhost local]# mkdir -p /usr/local/percona/pmm2#添加$PMM_DIR/bin至环境变量配置文件
