Before install the directory /user/local/mysql not existing.

And I do step by step

1. Download and exact by tar -xvzf command
2. find ./ -type f | xargs perl -pi -w -e ’s/cnf/conf/g;’

./configure –prefix=/usr/local/mysql –enable-local-infile
–with-tcp-port=4444 –with-mysqld-user=mysqlt
–with-base_dir=/usr/local/mysql –with-log=/usr/local/mysql/mysqld.log
–with-pid_file=/usr/local/mysql/mysqld.pid
-with-unix-socket-path=/tmp/mysqlt.sock –localstatedir=/var/lib/mysqlt
