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http://download.unix-center.net/mysql/mysql-5.0.51a-linux-i686-glibc23.tar.gz
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
[root@localhost local]# ln -s /usr/local/mysql/bin/* /usr/local/bin/
