Mysql Data directory and Binlog directory relocation method _mysql

If the entire process uses a MySQL user, it should be able to start normally.
If the root user is used, it may not start properly because the new directory permissions are not correct.
This may be the wrong hint:
/usr/local/mysql/libexec/mysqld:file '/home/mysql/mysqllog/binlog/mysql-bin.index ' not Found (errcode:2)

1. Stop MySQL service must be stopped first, very important.
#/etc/init.d/mysqld Stop
2. Modify MySQL configuration my.cnf:

#datadir =/usr/local/mysql/var
#log-bin =/usr/local/mysql/var/binlog/mysql-bin

DataDir =/home/mysql/mysqldata
Log-bin =/home/mysql/mysqllog/binlog/mysql-bin

3. Copy MySQL Data
# cp-rf/usr/local/mysql/var/*/home/mysql/mysqldata/

4. Start MySQL Service
#/etc/init.d/mysqld Start

If the entire process uses a MySQL user, it should be able to start normally.
If the root user is used, it may not start properly because the new directory permissions are not correct.
Use the following command to modify it:
# chown Mysql:mysql/home/mysql-r

If you use InnoDB notice the following modifications:

Innodb_data_home_dir =/home/mysql/mysqldata/
Innodb_log_group_home_dir =/home/mysql/mysqldata/
