That is the handbook of MySQL installing,but I got some error in my installing.
The problem is the mysql server can't start.It likes that:
[root@c0201 root]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Finally I solved this problem by command
[root@c0201 mysql]# cp support-files/my-medium.cnf /etc/my.cnf
cp：是否覆盖‘/etc/my.cnf’? y

2.How to start mysql server at sysyem up?
[root@c0201 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

3.Install jakarta-tomcat-connectors.

1.Why I can't connect the X server when install oracle 10g?
The problem is like that:"OUI-10025: 由于出现以下错误, 无法启动交互式安装会话: Can't connect to X11 window server using '202.197.*.*:0.0' as the value of the DISPLAY variable.。DISPLAY 环境变量应该设置为 <hostname>:<screen> 或 <IP address>:<screen>, 其中 <screen> 通常为 '0.0'。"
I solved this problem by command below.
[oracle@c0201 oracle]$ vi .bash_profile
#add a line: export DISPLAY=127.0.0.1:0.0
[oracle@c0201 oracle]$ export DISPLAY=127.0.0.1:0.0
[oracle@c0201 oracle]$ xclock
It dispeared a clock in graphic mode, everything is ok now.
