mysql快速入门

一、下载并解压

$ wget http://cdn.mysql.com/Downloads/MySQL-5.5/MySQL-5.5.42-1.el6.x86_64.rpm-bundle.tar

解压后得到以下几个文件：

$ tar -xvf MySQL-5.5.42-1.el6.x86_64.rpm-bundle.tar  

MySQL-shared-5.5.42-1.el6.x86_64.rpm

MySQL-shared-compat-5.5.42-1.el6.x86_64.rpm

MySQL-server-5.5.42-1.el6.x86_64.rpm

MySQL-devel-5.5.42-1.el6.x86_64.rpm

MySQL-test-5.5.42-1.el6.x86_64.rpm

MySQL-client-5.5.42-1.el6.x86_64.rpm

MySQL-embedded-5.5.42-1.el6.x86_64.rpm



二、安装

1、安装server

（1）# rpm -ivh MySQL-server-5.5.42-1.el6.x86_64.rpm



（2）若出现冲突错误，则是由于linux可能自带了mysql的库，需要先将之删除

# rpm -e mysql-libs.x86_64 --nodeps



2、安装client

# rpm -ivh MySQL-client-5.5.42-1.el6.x86_64.rpm



三、关于配置文件

# ls *.cnf

my-huge.cnf  my-innodb-heavy-4G.cnf  my-large.cnf  my-medium.cnf  my-small.cnf

# pwd

/usr/share/mysql

使用rpm方法进行安装时，配置文件放在/usr/share/mysql中，可根据需要放到其它地方。



四、启动及关闭

1、方式一：命令行方式

# mysqld_safe &

# mysqladmin -uroot shutdown



2、方式二：服务方式

# service mysql start

# service mysql stop

# service mysql restart



3、连接数据库开始使用

# mysql -u root -p

Enter password:
