本来想安装最新的5.6.13-1版本，下载下来后，依赖的包rpmlib无处下载，无法只得作罢。从Foreda8的安装光盘中找到了以下文件：
mysql-5.0.45-4.fc8.i386.rpm
mysql-connector-java-3.1.12-3.fc6.i386.rpm
mysql-connector-odbc-3.51.14r248-2.fc8.i386.rpm
mysql-libs-5.0.45-4.fc8.i386.rpm
mysql-server-5.0.45-4.fc8.i386.rpm
估计安装好MySQL有上面这些包就行了。
首先执行的是# rpm -ivh mysql-5.0.45-4.fc8.i386.rpm
warning: mysql-5.0.45-4.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2
error: Failed dependencies:
perl(DBI) is needed by mysql-5.0.45-4.fc8.i386
于是又到光盘里找来了perl-DBI-1.58-2.fc8.i386.rpm ，继续安装。
# rpm -ivh perl-DBI-1.58-2.fc8.i386.rpm
warning: perl-DBI-1.58-2.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2

这回不错，没啥问题了。再次安装mysql-5.0.45-4.fc8.i386.rpm看看：
# rpm -ivh mysql-5.0.45-4.fc8.i386.rpm
warning: mysql-5.0.45-4.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2

file /usr/bin/mysql_config from install of mysql-5.0.45-4.fc8 conflicts with file from package MySQL-devel-advanced-5.6.13-1.rhel5
file /usr/share/man/man1/mysql_config.1.gz from install of mysql-5.0.45-4.fc8 conflicts with file from package MySQL-devel-advanced-5.6.13-1.rhel5
原来是和之前安装的MySQL-devel-advanced-5.6.13-1.rhel5冲突了，于是执行下面命令删掉它。
# rpm -e MySQL-devel-advanced-5.6.13-1.rhel5
接下来再安装mysql-server-5.0.45-4.fc8.i386.rpm
# rpm -ivh mysql-server-5.0.45-4.fc8.i386.rpm
warning: mysql-server-5.0.45-4.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2
error: Failed dependencies:
mysql = 5.0.45-4.fc8 is needed by mysql-server-5.0.45-4.fc8.i386
perl-DBD-MySQL is needed by mysql-server-5.0.45-4.fc8.i386
又少一个perl-DBD-MySQL，从光盘中找来了perl-DBD-MySQL-4.005-2.fc8.1.i386.rpm 继续安：
# rpm -ivh perl-DBD-MySQL-4.005-2.fc8.1.i386.rpm
warning: perl-DBD-MySQL-4.005-2.fc8.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2
Preparing... ########################################### [100%]
1:perl-DBD-MySQL ########################################### [100%]
OK，万里长征又前进了一步，再安装mysql-5.0.45-4.fc8.i386.rpm,成功了
# rpm -ivh mysql-5.0.45-4.fc8.i386.rpm
warning: mysql-5.0.45-4.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2
Preparing... ########################################### [100%]
1:mysql ########################################### [100%]
这把取得阶段性成果了。然后执行
# rpm -ivh mysql-server-5.0.45-4.fc8.i386.rpm
warning: mysql-server-5.0.45-4.fc8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2

呦西，看来安上了。看看3306端口有没有被监听：
# netstat -nat
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:59782 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN

tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
没有，估计安好后MySQL没有自动启动。
进入目录：
# cd /etc/rc.d/init.d
执行# ./mysqld start （Usage: ./mysqld {start|stop|status|condrestart|restart}）
Initializing MySQL database: 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:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/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 /usr/bin/mysqlbug script!

再看看端口3306
# netstat -nat
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:59782 0.0.0.0:* LISTEN

tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
再在命令行里输入MySQL，mysql的命令行就出来了。
执行show databases;
熟悉的information_schma,mysql,test就显示出来了。
到此安装成功。
如果上文有什么问题或是疑点，请指点，先谢谢了。
