Linux AS4 下装mysql 的问题

在linux AS4 下装mysql 5.0.18.0，
[root@localhost home]# rpm -ivh MySQL-server-standard-5.0.18-0.rhel4.i386.rpm

提示
error: Failed dependencies:
       MySQL conflicts with mysql-4.1.12-3.RHEL4.1.i386



然后我想卸载mysql-4.1.12-3.RHEL4.1.i386
[root@localhost home]# rpm -e mysql-4.1.12-3.RHEL4.1

又提示
error: Failed dependencies:
       libmysqlclient.so.14 is needed by (installed) cyrus-sasl-sql-2.1.19-5.EL4.i386

郁闷了好久也没找到方法......

 

 

之后下载了一个MySQL-shared-compat-4.1.10-0.i386.rpm
地址是http://www.wesmo.com/rpm2html/contributed/RPMS/MySQL-shared-compat-4.1.10-0.i386.html
好象包括libmysqlclient.so.14 ，不管是什么了，就装上了
[root@localhost home]# rpm -ivh MySQL-shared-compat-4.1.10-0.i386.rpm
warning: MySQL-shared-compat-4.1.10-0.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5
Preparing...             ########################################### [100%]
1:MySQL-shared-compat ########################################### [100%]
然后我又运行[root@localhost home]# rpm -e mysql-4.1.12-3.RHEL4.1
这次就一个警告
warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave
（不知道什么意思，忘高手解释，是系统保存一个备份吗？为什么呢？）
又执行，重装mysql 5.0.18.0
[root@localhost home]# rpm -ivh MySQL-server-standard-5.0.18-0.rhel4.i386.rpm
warning: MySQL-server-standard-5.0.18-0.rhel4.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5

1:MySQL-server-standard   ########################################### [100%]
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.

 

OK搞定了！
