Build a kafka cluster environment in a docker container
Kafka cluster management and status saving are implemented through zookeeper. Therefore, you must first set up a zookeeper cluster.
Zookeeper cluster Construction
I. software environment:
The zookeeper cluster requires more than half of the nodes to survive for external services. Therefore, the number of servers should be 2 * N + 1. Here, three nodes are used to build the zookeeper cluster.
1. All three linux servers are created using doc

Oracle provides two ways to back up control files:
1. Generate scripts that can reconstruct control files2. Backup binary control files
Let's take a look at how to get the script to rebuild the control file.
Oracle provides the following command:
ALTER DATABASE backup Controlfile to trace;

Install MariaDB and MySQL
MariaDB can be used to replace enhanced MySQL versions, but MariaDB can also be installed when MySQL is installed. (This makes sense. For example, you want to migrate data from one database/application to another database/application .)
The following describes how to install MariaDB when MySQL is installed.
Download the latest binary compilation package tar.gz (currently mariadb-5.5.24-linux-x86_64.tar.gz) and decompress it to your custom directory. This document assume
that can be created by each real user ID.
/proc/sys/fs/inotify/max_user_watches
Default Value: 8192
Specifies the maximum number of watches associated with each inotify instance, that is, the maximum number of directories that each inotify instance can monitor. If the number of monitored files is large, you need to increase the value according to the actual situation.
Note:
1.
Max_queued_events is the maximum length of the queue managed by Inotify. The more frequently the file system change
