PMM部署遇到的坑
| 系统 | 内核版本 |
|---|---|
| CentOS release 6.4 (Final) | 2.6.32-358.el6.x86_64 |
1.公司环境pull不下来
在自己的环境pull下来然后save image
[root@slave oracle]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/percona/pmm-server 1.2.0 eb82a0e154c8 2 weeks ago 1.266 GB
docker.io/percona/pmm-server latest eb82a0e154c8 2 weeks ago 1.266 GB
[root@slave oracle]# docker save eb82a0e154c8 > pmm-server.tar
[root@slave oracle]# scp pmm-server.tar 10.4.2.43:~/

[root@test2 ~]# docker load < pmm-server.tar repostory和tag是

[root@test2 ~]# docker tag abdf7c1b7a63 docker.io/percona/pmm-server:1.2.0 2.docker容器无法启动 no such file or directory statusCode=404
这个搜了半天不知道是什么原因,怀疑是内核版本太低
因为CentOS6.4自带内核版本是2.6.32-358.23.2.el6.x86_64，而Docker要求内核版本大于3.0，推荐3.8以上的内核
https://yq.aliyun.com/ziliao/48262
遂升级内核
wget http://elrepo.org/linux/kernel/el6/x86_64/RPMS/kernel-lt-3.10.107-1.el6.elrepo.x86_64.rpm如果连接不对,自己去http://elrepo.org/linux/kernel/el6/x86_64/RPMS/看一眼,找一个合适的
rpm -ivh kernel-lt-3.10.107-1.el6.elrepo.x86_64.rpm修改grub.conf
vi /etc/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/mapper/VolGroup-LogVol00
# initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (3.10.107-1.el6.elrepo.x86_64)
root (hd0,0)
kernel /vmlinuz-3.10.107-1.el6.elrepo.x86_64 ro root=/dev/mapper/VolGroup-LogVol00 rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_LVM_LV=VolGroup/LogVol00 rd_NO_DM rhgb quiet numa=off elevator=deadline
initrd /initramfs-3.10.107-1.el6.elrepo.x86_64.img
title CentOS (2.6.32-358.el6.x86_64)

initrd /initramfs-2.6.32-358.el6.x86_64.img
现在title CentOS (3.10.107-1.el6.elrepo.x86_64)在 0 号位置,所以将
default=1改为default=0
重启os重启后
[root@test2 ~]# cat /etc/redhat-release
CentOS release 6.9 (Final)
[root@test2 ~]# uname -r
3.10.107-1.el6.elrepo.x86_64再次创建container成功
[root@test2 ~]# docker load < pmm-server.tar
[root@test2 ~]# docker images

PMM-server选择一个内核版本搞的服务器就行
PMM-client无所谓
- pmm-data 状态为Exited
内核版本低
4.MySQL dashboard没数据
防火墙没关
pmm-admin check-network
centos 7
停止： systemctl disable firewalld
禁用： systemctl stop firewalld
5.容器时区为UTC与我们系统CST差八个小时
进入容器
