装2个mysql的问题。

crisman

昨天在自己的本子上装了2个mysql. 是没有问题的。第一个按照常规编译安装的。
第2个 在编译的时候加了如下参数
./configure  --with-mysqld-user=mysql2 --prefix=/usr/local/mysql2 --with-tcp-port=3307 --datadir=/usr/local/mysql2/var  --with-unix-socket-path=/tmp/mysql2.sock
后来都成功安装了。

但是今天到公司。再这样装。
到初始化数据库的时候。出这个错。我在本子上没这个错的。
./bin/mysql_install_db --user=mysql2 --datadir=/usr/local/mysql2/var/
Installing MySQL system tables...
090708  9:44:21 [Warning] Ignoring user change to 'mysql2' because the user was set to 'mysql' earlier on the command line

090708  9:44:21 [Warning] Ignoring user change to 'mysql2' because the user was set to 'mysql' earlier on the command line

ERROR: 1005  Can't create table 'db' (errno: 13)
090708  9:44:21 [ERROR] Aborting

请问大家有类似经验么

crisman

我已经指定了不同的sockt.不同的端口。不同的用户，不同的datadir .
但是初始化数据库的时候出错了。我本子上就可以。服务器上就不行。

crisman

还是同样的错。我本子上怎么可以。我昏迷了
