1. Check whether other versions of MYSQL data are installed in the system
#yum list installed | grep mysql
#yum -y remove mysql-libs.x86_64
2. Installation and configuration
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
# rpm -ivh mysql-community-release-el6-5.noarch.rpm
# yum repolist all | grep mysql
Install MYSQL database
# yum install mysql-community-server -y
Set it to start at boot (2, 3, and 4 are all on, which means it starts automatically at boot)
# chkconfig --list | grep mysqld
# chkconfig mysqld on
3. Set up remote root start mysql
# service mysqld start
set root password
# mysql_secure_installation
Log in to the root account
# mysql -uroot -p
Create a remote root user
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'The password you set' WITH GRANT OPTION;
mysql> flush privileges;
Fourth, set utf-8 encoding View the original encoding of mysql:
mysql> show variables like 'character%';
set encoding
# vi /etc/my.cnf
As follows (less supplement):
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
sql_mode='NO_ENGINE_SUBSTITUTION'
[mysql]
default-character-set = utf8
[mysql.server]
default-character-set = utf8
[mysqld_safe]
default-character-set = utf8
[client]
default-character-set = utf8
restart mysql
# service mysqld restart
Check out the encoding again:
# mysql -uroot -p
mysql> show variables like 'character%';
