4 Installing MySQL
Mysql-5.6.20-1.el6.x86_64.rpm-bundle.tar
See if Mysql:rpm-qa|grep MySQL is installed
View system current MySQL process
[email protected] ~]ps aux |grep mysq*
If you have previously installed MySQL other version or reinstall, remove all MySQL directory residue, execute the following command
RPM-E--nodeps mysql-server-5.6.17-1.el6.i686
Rm-rf/var/lib/mysql
Rm-rf/usr/lib/mysql
Rm-rf/home/undoner/mysqldata (Mysqldata can also customize other folders for users)
Rm-rf/etc/my.cnf
Rm-rf/usr/my.cnf
Rm-rf/root/.mysql_secret
The following are three ways to install:
A default RPM installation (using default configuration)
B Custom RPM installation (custom database path, MY.CNF configuration, log path, etc.)
C Compile Package Custom installation using source code (not included)
D use CentOS built-in Yum tool for automatic installation (lower version)
--------------------------------------------------------
A default RPM installation (using default configuration)
Go to the downloaded MySQL directory and execute the following command
[Email protected] ~]# Cd/home/undoner/software
Unpack the Tarball
[Email protected] ~]# TAR-XVF Mysql-5.6.20-1.el6.x86_64.rpm-bundle.tar
Run RPM file, server must be installed, other optional.
[Email protected] ~]cd/home/undoner/software/
[Email protected] ~]rpm-iv mysql-server-5.6.20-1.el6.x86_64.rpm
[Email protected] ~]rpm-iv mysql-client-5.6.20-1.el6.x86_64.rpm
[Email protected] ~]rpm-iv mysql-devel-5.6.20-1.el6.x86_64.rpm
(direct installation will prompt for no default MySQL group and MySQL user)
Alternative: Add MySQL groups and users, but not.
[[email protected] ~]# Groupadd MySQL
[[email protected] ~]# useradd-g MySQL MySQL
[[email protected] ~]# passwd mysql//change user password
MySQL default installation directory description
/var/lib/mysql Database files
/usr/share/mysql commands and configuration files
/usr/bin (Mysqladmin, mysqldump and other commands)
Modify permissions for/var/lib/mysql
The directory has full permissions for any user
[Email protected] ~]chmod-r 777/var/lib/mysql
Alternative: If a MySQL user is established, change the directory owner from root to MySQL
[Email protected] ~]chown-r Mysql/var/lib/mysql
Start MySQL:
[[email protected] ~]service mysql status
Result: The display "SUCCESS" is already running
Show "FAILED" is not running
Start: [[email protected] ~]service MySQL start
Close: [[email protected] ~]service MySQL stop
MySQL service some other commands
A. See if MySQL is in the auto-start list: #/sbin/chkconfig--list
B. Add MySQL to System self-boot service group: #/sbin/chkconfig--add MySQL
C. remove MySQL from the Startup service group: #/sbin/chkconfig--del MySQL
D, stop MySQL service: # service MySQL Stop
E, script start MySQL service: #/etc/rc.d/init.d/mysqld start
F, script stop MySQL service: #/etc/rc.d/init.d/mysqld stop
The default is boot-start! Status 2-5 for Startup
[Email protected] ~]/sbin/chkconfig--list
View the current default root account password (installation generated random values)
[Email protected] ~]vim/root/.mysql_secret
Copy the current root account password and log in to MySQL
[Email protected] ~]mysql-uroot-p
Modify the current password after logging in to MySQL
mysql> SET PASSWORD = PASSWORD (' root ');
mysql> show databases;
Mysql> quit
Log in again with the new password root to see if remote connection is allowed (default deny), add remote root user access
mysql> use MySQL;
Mysql> select Host,user,password from user;
Mysql> Grant all privileges on * * to [e-mail protected] "%" identified by ' root ' with GRANT option;
Change the MySQL default character set (the default character set is the same as the operating system character set, so no setting is required)
To view the MySQL character set:
Mysql> Show variables like ' character_set_% ';
Add a MySQL profile, set the default encoding character set
[[email protected] ~]service MySQL stop
[Email protected] ~]cp/usr/share/mysql/my-default.cnf/etc/my.cnf
[Email protected] ~]vim/etc/my.cnf
