安装mysql 遇到的麻烦 求解答

环境： centos 5


按照如下方法安装mysql，

usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.29-rc.tar.gz
cd mysql-5.1.29-rc/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-innodb
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf
cd ../

　　①、以mysql用户帐号的身份建立数据表：
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql


　　　②、启动MySQL
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &


最近的一次是按照上面安装的，就最后一步的时候不行，启动不了，别的都没事




当我启动的时候提示：

[root@localhost /]# /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &   （只有这一行使我输入的，为什么下面又出来一个[root@localhost /]#）
[1] 15639
[root@localhost /]# 081126 23:36:12 mysqld_safe Logging to '/usr/local/webserver/mysql//data/localhost.localdomain.err'.
081126 23:36:12 mysqld_safe Starting mysqld daemon with databases from /usr/local/webserver/mysql//data
081126 23:36:13 mysqld_safe mysqld from pid file /usr/local/webserver/mysql//data/localhost.localdomain.pid ended

到这就不动了

查看进程和端口mysql根本就没有启动。


下面是：localhost.localdomain.err 的信息
［root@localhost ~]# cat /usr/local/webserver/mysql//data/localhost.localdomain.err
