CMake source code compilation Installation mysql-5.5.32: Pits encountered by multiple instances

Pit 1: mysql-5.5.32.tar.gz source package not found
It took a lot of effort to find:
MySQL Source package:
https://downloads.mysql.com/archives/community/

Download path
Https://downloads.mysql.com/archives/get/file/mysql-5.5.32.tar.gz
How did I find the fish?

Pit 2:cmake configuration error because \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ CMake compile parameters correctly:

Pit 3:mysql After a multi-instance execution starts, the port does not start, and the view log finds an error.

Key error log points are:

/application/mysql-5.5.32/bin/mysqld:can ' t change dir to '/application/3306/data/' (errcode:2)

This was carefully examined because the DataDir path was pointed to/application/3306/data in the multi-instance configuration file.
3307 Example error is the same.
Modify the datadir=/data/3307/data in 3306 and 3,307 multi-instance my.cnf after starting two instances OK

Although the toss for a long while, but still very gratified to solve the problem, here need to thank, http://zpz.name/1592/

* * Fix error after compiling mysql: Can ' t change dir to '/var/mysql-dmysql_unix_addr=/var/mysql/mysqld.sock/'
Possible problems and solutions:

1. may be/usr/local/mysql/data/rekfan.pid file does not have permission to write
Workaround: Give permission, execute "chown-r mysql:mysql/var/data" "Chmod-r 755/usr/local/mysql/data" and restart mysqld!

2. The MySQL process may already exist in the process
WORKAROUND: Use the command "Ps-ef|grep mysqld" to see if there is a mysqld process, kill with "kill-9 process number" and then restart mysqld!

3. It may be the second time that MySQL is installed on the machine, with residual data affecting the start of the service.
Workaround: Go to MySQL data directory/data See, if there is mysql-bin.index, quickly delete it, it is the culprit. I am using the third method to solve! http://blog.rekfan.com/?p=186

4.mysql The/ETC/MY.CNF profile is used when the configuration file is not specified at startup, please open this file to see if there is a specified data directory (DATADIR) under the [Mysqld] section.
WORKAROUND: Please set this line under [mysqld]: DataDir =/usr/local/mysql/data

5.skip-federated Field Issues
Workaround: Check the/etc/my.cnf file for any skip-federated fields that have not been commented out, and if so, comment them out immediately.

6. Error log directory does not exist
Workaround: Use "Chown" "chmod" command to give MySQL owner and permissions

7.selinux, if it is a CentOS system, the default is to turn on SELinux
Workaround: Turn it off, open the/etc/selinux/config, change the selinux=enforcing to selinux=disabled, and then save the restart machine and try again. **

4 Finally I send the correct multi-instance configuration file:
