众所周知的原因安装PMM2

1、众所周知的原因安装PMM2

版本也是2.42.0，最新的版本

[root@pmm2 ~]# cat /etc/docker/daemon.json
{
    "registry-mirrors": [
        "https://docker.m.daocloud.io",
        "https://mirror.baidubce.com"
    ]
}

[root@pmm2 ~]# docker image inspect percona/pmm-server:2 | grep -i version
        "DockerVersion": "20.10.25",
                "org.opencontainers.image.version": "2.42.0"

[root@pmm2 ~]# docker ps
CONTAINER ID   IMAGE                  COMMAND                CREATED          STATUS                    PORTS                                           NAMES
aea7f134683e   percona/pmm-server:2   "/opt/entrypoint.sh"   18 minutes ago   Up 18 minutes (healthy)   80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp   pmm-server

2、留存docker image

[root@pmm2 ~]# docker images
REPOSITORY           TAG       IMAGE ID       CREATED       SIZE
percona/pmm-server   2         8a3a13ce2d13   4 weeks ago   2.39GB

[root@pmm2 ~]# docker save 8a3a13ce2d13 > /root/pmm2_2.42.0.tar

[root@pmm2 ~]# du -sh pmm2_2.42.0.tar
2.3G    pmm2_2.42.0.tar

3、导入测试

#删除重建，或者其他导入docker，并修改tag

[root@pmm2 ~]# docker load < /root/pmm2_2.42.0.tar
0e2e8dd6d8eb: Loading layer [==================================================>]  115.1MB/115.1MB
c6e5cc92bae4: Loading layer [==================================================>]  2.298GB/2.298GB
Loaded image ID: sha256:8a3a13ce2d13ea94b2af803aba4797b8b18ec8b1f1c6f4b6205043b19bbb6c8e

[root@pmm2 ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
<none>       <none>    8a3a13ce2d13   4 weeks ago   2.39GB

[root@pmm2 ~]# docker tag 8a3a13ce2d13 percona/pmm-server:2

[root@pmm2 ~]# docker images
REPOSITORY           TAG       IMAGE ID       CREATED       SIZE
percona/pmm-server   2         8a3a13ce2d13   4 weeks ago   2.39GB

4、运行

这里不会再去pull image了，直接就可以把容器运行起来

[root@pmm2 ~]# wget -qO - https://www.percona.com/get/pmm | /bin/bash
Gathering/downloading required components, this may take a moment

Checking docker installation - installed.

Starting PMM server...
Created PMM Data Volume: pmm-data
Created PMM Server: pmm-server
        Use the following command if you ever need to update your container by hand:
        docker run -d -p 443:443 --volumes-from pmm-data --name pmm-server --restart always percona/pmm-server:2

PMM Server has been successfully setup on this system!

You can access your new server using one of the following web addresses:
        https://172.17.0.1:443/
        https://192.168.5.140:443/
        https://127.0.0.1:443/

The default username is 'admin' and the password is 'admin' :)
Note: Some browsers may not trust the default SSL certificate when you first open one of the urls above.
If this is the case, Chrome users may want to type 'thisisunsafe' to bypass the warning.

Enjoy Percona Monitoring and Management!

5、pmm脚本
