mysql重新安装时，出现以下问题，如何解决！

hhyyy9

[root@www mysql-4.0.18]# /usr/local/mysql/bin/mysql_install_db
Didn't find /opt/mysql/libexec/mysqld
You should do a 'make install' before executing this script
[root@www mysql-4.0.18]# /usr/local/mysql/share/mysql/mysql.server start
/usr/local/mysql/share/mysql/mysql.server: cd: /opt/mysql: No such file or directory
Can't execute /opt/mysql/bin/mysqld_safe from dir /opt/mysql
[root@www mysql-4.0.18]#


我之前是用源码包安装的，请问是不是没有卸载干净？
rpm -qa | grep mysql不行么？

如何解决

test2002

检查/opt/mysql/libexec/mysqld这个文件有没有。
卸载 rpm -e mysql

先rpm -e mysql*
然后编译安装mysql
到你的mysql安装目录下的include下找个叫mysql.server的文件
把它拷贝到你定义的bindir或sbindir路径里改名为mysqld
