Configuring mysql

authority management:

1 Create mysql group, and user
    groupadd mysql
    useradd -g mysql mysql
    
2. Modify the / usr / local / MySQL permissions
    chown -R mysql:mysql /usr/local/mysql
    
    
Initial Configuration:
1.cd /usr/local/mysql
2.scripts/mysql_install_db

When you start MySQL service will be first in looking my.cnf / etc directory, the search will not find " $ basedir / my.cnf " , in this case is / usr / local / MySQL / my.cnf

View / whether there is etc my.cnf, we have to change the name to prevent interference
 1.mv /etc/my.cnf / etc / my.cnf.bak

Add Service (mysql service into the / etc / init.d), and set the boot from the start:
 1.CP /usr/local/mysql/support-files/mysql.server /etc/init.d/ MySQL
 2 .chkconfig MySQL ON
 3 .service MySQL Start

Configuration environment variable:
1.vi / etc / Profile
 2 . Join in the file:
    export PATH=$PATH:/usr/local/mysql/bin
3.source /etc/profile
