* Of course, many times we have created a good other user to complete the day-to-day operation if you do not create a MySQL user, modify the Mysqld_safe file in the Mysql/bin directory;//pro-Test success

Specific steps:

[Root@master bin]# vim mysqld_safe user= ' MySQL ' modified for user= ' Hadoop '//own user The following steps are basically the same * [root@slave1 data]# service MySQL STA RT Starting MySQL ... error!
The server quit without updating PID file (/home/hadoop/ruanjian/mysql/data/slave1.hadoop.pid).

Create the data directory under MySQL user and unzip

[Root@master data]# tar-zxvf mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz
[root@master data]# MV mysql-5.6.12-linux-glibc2.5-x86_64 MySQL//rename

Set permissions

[Root@master data]# chown-r mysql:mysql MySQL

Switch users and enter the Mysql/scripts directory

[Root@master data]# su mysql
[mysql@master data]$ cd mysql/scripts/
[Mysql@master scripts]$

Installation (directory based on your own MySQL extract directory set itself)

[Mysql@master scripts]$./mysql_install_db--user=mysql--basedir=/home/mysql/data/mysql--datadir=/home/mysql/data /mysql/data

For your system, REMEMBER to SET A PASSWORD for the MySQL root USER! To does so, start the server, then issue the following commands:/home/mysql/data/mysql/bin/mysqladmin-u root password ' NE  W-password '/home/mysql/data/mysql/bin/mysqladmin-u root-h master.hadoop password ' new-password ' Alternatively you can Run:/home/mysql/data/mysql/bin/mysql_secure_installation which'll also give you the option of removing the test datab ASEs and anonymous user created by default.
This is strongly recommended for production servers.
