PMM部署遇到的坑

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@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

1
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

1
rpm -ivh kernel-lt-3.10.107-1.el6.elrepo.x86_64.rpm

修改grub.conf

# NOTICE: You have a /boot partition. This means that

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

Note

PMM-server选择一个内核版本搞的服务器就行

PMM-client无所谓

3.pmm-data 状态为Exited
内核版本低

4.MySQL dashboard没数据
防火墙没关

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
