Use rpm package hands-on to teach you how to install MySQL (MySQL-server-5.6.23 for CentOS6.5 _ 64bit)

1. Check whether MySQL is installed on the operating system.
[Root @ mydb1 backup] # rpm-qa | grep mysql
Qt-mysql-4.6.2-26.el6_4.x86_64
Mysql-5.1.71-1.el6.x86_64
Mysql-server-5.1.71-1.el6.x86_64
Mysql-devel-5.1.71-1.el6.x86_64
Mysql-libs-5.1.71-1.el6.x86_64

2. Delete MyQL (the mysql-libs that comes with the RedHat6.3 Server is a mysql-libs-5.1.61-4.el6.x86_64 and may conflict with the mysql-libs of a later version)
Yum remove mysql-libs

Iii. Install MySQL with RPM (the root user does not need to create a mysql group or a mysql user in advance. It will be automatically created during mysql-server Installation)
[Root @ mydb1 backups] # rpm-pql MySQL-server-5.6.23-1.el6.x86_64.rpm | more
[Root @ mydb1 backup] # rpm-ivh MySQL-server-5.6.23-1.el6.i686.rpm
[Root @ mydb1 backup] # rpm-ivh MySQL-client-5.6.23-1.el6.x86_64.rpm

4. Create an installation directory
Mkdir-p/u01/app/mysql/data/mysql3306/data
Mkdir-p/u01/app/mysql/data/mysql3306/log
Mkdir-p/u01/app/mysql/log/mysql3306/iblog
Mkdir-p/u01/app/mysql/log/mysql3306/binlog
Mkdir-p/u01/app/mysql/data/mysql3306/tmp

5. Configure my. cnf
Cp/usr/my. cnf/u01/app/mysql/data/mysql3306/my. cnf

Vi/u01/app/mysql/data/mysql3306/my. cnf
[Client]
Port = 3306
Socket =/u01/app/mysql/data/mysql3306/run/mysql. sock

[Mysql]

Log-bin =/u01/app/mysql/log/mysql3306/binlog
Relay-log =/u01/app/mysql/log/mysql3306/binlog/relaylog

Innodb_force_recovery = 0

4. Execute the MySQL installation script
Sh init3306.sh

Rm-rf/u01/app/mysql/mysql3306/data /*
Rm-rf/u01/app/mysql/log/mysql3306/iblog /*
Rm-rf/u01/app/mysql/log/mysql3306/binlog /*
Chmod-R 777/u01/app/mysql/data/mysql/3306/data /*
Chmod-R 777/u01/app/mysql/log/mysql3306/iblog /*
Chmod-R 777/u01/app/mysql/log/mysql3306/binlog /*
Chmod 755/u01/app/mysql/data/mysql3306/my. cnf
Mysql_install_db -- defaults-file =/u01/app/mysql/data/mysql3306/my. cnf -- basedir =/usr/-- datadir =/u01/app/mysql/data/mysql3306/data

5. Check whether the MySQL service exists. If mysql is not added to the service, start the service.
Chkconfig -- add mysqld
Chkconfig -- level 2345 mysqld on
Check whether startup setting is successful
[Root @ mydb1 ~] # Chkconfig -- list | grep mysql
Mysql 0: off 1: off 2: on 3: on 4: on 5: on 6: off

6. Start MySQL
[Root @ mydb1 ~] # Service mysql start
Starting MySQL SUCCESS!

7. How to view the MySQL running status
[Root @ mydb1 ~] # Service mysql status
SUCCESS! MySQL running (4104)

8. Check the initial MySQL password
[Root @ mydb1 ~] # Cat/root/. mysql_secret
# The random password set for the root user at Mon Mar 30 15:04:58 2015 (local time): B15xIBTq3xAoGRVx

9. log on to MySQL
[Root @ mydb1 ~] # Mysql-u root-p
Enter password:
Welcome to the MySQL monitor. Commands end with; or \ g.

MySQL system parameter configuration

Do not start MySQL first, copy the data directory to the new location/mysqldata/mysql_data/, and modify the permission

Cd/var/lib/mysql/

Cp-r */mysqldata/mysql_data/

[Root @ wmserpmysql1/] # chown mysql: mysql-R/mysqldata

Delete the original default parameter file

[Root @ wmserpmysql1 mysql] # rm/usr/my. cnf

Rm: remove regular file '/usr/my. cnf '? Y

Copy the new parameter file and modify

[Root @ wmserpmysql1 mysql] # pwd
