这几天研究了好久，终于被我知道了如何在Linux下安装mysql的二进制源代码包，最终解决了ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)的权限问题，真的是感慨万分啊，只想把他写出来，让自己以后不要忘记了，，好了，废话不多说了，看看我的安装步骤吧！
1.下载mysql-5.0.51a-linux-i686-glibc23.tar.gz，下载地址为
2.把下载的文件放在你的主目录，在终端输入ls,如下:
[root@localhost mysql]# ls
Desktop Documents Download Music mysql-5.0.51a-linux-i686-glibc23.tar.gz Pictures Public Templates Videos
3.然后用tar -zxvf mysql-5.0.51a-linux-i686-glibc23.tar.gz命令解压到当前目录，如下：
[root@localhost mysql]# tar -zxvf mysql-5.0.51a-linux-i686-glibc23.tar.gz
[root@localhost mysql]# ls
Desktop Download mysql-5.0.51a-linux-i686-glibc23 Pictures Templates
Documents Music mysql-5.0.51a-linux-i686-glibc23.tar.gz Public Videos
4.因为用的是源代码，所以要把文件copy到安装目录/usr/local/下，才能运行!
[root@localhost mysql]# cp –rf mysql-5.0.51a-linux-i686-glibc23 /usr/local/
5.查看系统有没有安装过mysql,查找rpm,如下:
[root@localhost mysql]# rpm –qa | grep mysql
有的话一个一个删除掉，用rpm -e命令,然后查找一下残留的文件:
[root@localhost mysql]# cd /
[root@localhost /]# find / -name mysql
如果查找到rm -rf filename删除.
[root@localhost /]# find / -name my.cnf
如果查找到删除，一般my.cnf是在/etc/my.cnf这里.
6.链接到mysql,如下：
[root@localhost /]# cd /home/mysql
[root@localhost mysql]# ln -s mysql-5.0.51a-linux-i686-glibc23 /usr/local/mysql
7.初始化mysql表格，安装 mysql 默认数据库，如下：
[root@localhost mysql]# cd /usr/local/mysql
[root@localhost mysql]# scripts/mysql_install_db --user=mysql
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!

8.修改目录权限，如下：
[root@localhost mysql]# cd /usr/local
[root@localhost local]# chgrp -R mysql mysql-5.0.51a-linux-i686-glibc23
[root@localhost local]# chgrp -R mysql mysql
[root@localhost local]# chown -R mysql mysql-5.0.51a-linux-i686-glibc23/data
[root@localhost local]# chown -R mysql mysql/data

9.启动mysql_safe,如下：
[root@localhost local]# bin/mysqld_safe --user=mysql --socket=/tmp/mysql.sock --port=3306 &
[1] 26860
[root@localhost local]# nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /usr/local/mysql/data
查看一下 3308 端口是否已经在监听：
netstat -anp|grep LISTEN
10.添加到系统自启动，如下：
[root@localhost local]# cp mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@localhost local]# chkconfig --add mysqld
11.启动mysql服务进程,如下：
[root@localhost local]# /etc/init.d/mysqld start
Starting MySQL [ OK ]
12.给 root 指定密码为"python",host为localhost ，如下：
[root@localhost local]# bin/mysqladmin --socket=/tmp/mysql.sock --port=3306 -u root -h localhost password 'python'
13.登录root,并给root授权!如下所示：
[root@localhost local]# bin/mysql --port=3306 -u root -p -S /tmp/mysql.sock
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.0.51a MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> grant all privileges on *.* to 'root'@'localhost' identified by 'python';
Query OK, 0 rows affected (0.54 sec)#[给使用localhost连接的root用户以所有权限]
mysql>flush privileges;
Query OK, 0 rows affected (0.26 sec)#[刷新用户权限列表，更新权限]
mysql> quit
Bye
14.新建一个用户，如下：
//登录MYSQL
[root@localhost local]# bin/mysql --port=3306 -u root -p -S /tmp/mysql.sock
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.0.51a MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
//使用mysql数据库
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
//创建用户
mysql> insert into mysql.user(Host,User,Password) values("localhost","django",password("django"));
Query OK, 1 row affected, 3 warnings (0.60 sec)
//刷新系统权限表
mysql> flush privileges;
Query OK, 0 rows affected (0.08 sec)
这样就创建了一个名为：django 密码为：django 的用户。
//然后登录一下
mysql> exit;
Bye
[root@localhost local]# bin/mysql --port=3306 -u django -p -S /tmp/mysql.sock
Enter password: //输入码
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.0.51a MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> //登录成功！
mysql> exit;
Bye
15.给新建的用户账户授权，如下：
//登录MYSQL（有ROOT权限）。我里我以ROOT身份登录.
[root@localhost local]# bin/mysql --port=3306 -u root -p -S /tmp/mysql.sock
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
//首先为用户创建一个数据库(django_demo)
mysql> create database django_demo;
Query OK, 1 row affected (0.41 sec)
//授权django用户拥有django_demo数据库的所有权限。
mysql> grant all privileges on django_demo.* to 'django'@'localhost' identified by 'django';
Query OK, 0 rows affected (0.13 sec)
//刷新系统权限表
mysql> flush privileges;
Query OK, 0 rows affected (0.09 sec)
