安装MySQL后MySQL启动不了……

Constantin

红旗高级服务器4.1下安装MySQL出现的问题：

[root@localhost root]# cd /
[root@localhost /]# cd usr/local
[root@localhost local]# ln -s mysql-standard-5.0.19-linux-i686 mysql
[root@localhost local]# cd mysql
[root@localhost mysql]# scripts/mysql_install_db --user=mysql
Installing all prepared tables
Fill help tables

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:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
See the manual for more instructions.

NOTE:  If you are upgrading from a MySQL <= 3.22.10 you should run
the ./bin/mysql_fix_privilege_tables. Otherwise you will not be
able to use the new GRANT command!

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:
cd sql-bench ; perl run-all-tests

Please report any problems with the ./bin/mysqlbug script!

[root@localhost mysql]# cd bin
[root@localhost bin]# ./mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

不知什么地方出错了，请高手们指教……

已经试过提示的命令，比如说：
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
服务器没启动，设置不了密码。

我想问题应该出在这里：
Starting mysqld daemon with databases from /var/lib/mysql
在/var/lib/mysql下能找到
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock'这里所提到的'mysql.sock'

请问接下来要如何操作才能启动MySQL呢 ?

找到问题所在，查看了文章，做了如下步骤，还是无法启动：
