CentOS 6.5下二进制安装 MySQL 5.6

CentOS 6.5 二进制安装MySQL 5.6

1:查看系统版本

[root@10-4-5-9 mysql]# cat /etc/redhat-release
CentOS release 6.5 (Final)

2:下载MySQL5.6二进制包

#wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20-linux-glibc2.5-i686.tar.gz

3:添加用户和组

#groupadd mysql
#useradd -g mysql mysql

4:安装mysql到/usr/local/mysql下

#cd /usr/local

#tar zxvf /{MySQL5.6_path}/mysql-{version}.tar.gz

例如我的配置路径为:
#cd /usr/local
#tar zxvf /root/mysql-5.6.20-linux-glibc2.5-i686.tar.gz

5:修改解压后文件夹名为 mysql

#mv mysql-5.6.20-linux-glibc2.5-i686 mysql

6:修改mysql的各级文件夹和文件的创建者、创建组为mysql(注意语句后面有个.

cd mysql
chown -R mysql .
chgrp -R mysql .

7:至此mysql已经安装完了,但还需要初始化,初始化mysql表、test表、infomation表等。

#scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

 

#cp support-files/mysql.server /etc/init.d/mysqld

 

--user=mysql 
--basedir=/usr/local/mysql 
--datadir=/usr/local/mysql/data

  

PS:该步骤有可能会报错误
安装需要的包即可:libstdc++.so.6和libaio.so.1和libncurses.so.5

  

8:修改配置文件

[root@10-4-5-9 mysql]# cp my.cnf /etc/my.cnf
/usr/local/mysql
[root@10-4-5-9 mysql]# vi /etc/my.cnf
[mysqld]中添加:

basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
server_id = 1

  

9:启动mySQL服务

 #ln -s /usr/local/mysql/bin/mysql /usr/bin

 

#service mysqld start

  

10:登陆MySQL并且删除空用户

mysql> SELECT user,host,password FROM mysql.user;
+------+-----------+----------+
| user | host      | password |
+------+-----------+----------+
| root | localhost |          |
| root | 10-4-5-9  |          |
| root | 127.0.0.1 |          |
| root | ::1       |          |
|      | localhost |          |
|      | 10-4-5-9  |          |
+------+-----------+----------+
6 rows in set (0.00 sec)

mysql> UPDATE mysql.user set password = PASSWORD('gechong') WHERE user = 'root';

mysql> DROP USER ''@localhost;

mysql> FLUSH PRIVILEGES;
