my.cnf文件，port端口？（急）解决方案

my.cnf文件，，port端口？？（急）
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
my.cnf文件里面就这东东，纠结了2天，找不到port，怎么去修改默认端口，求高手指点~~

16 # The following options will be passed to all MySQL clients

 24 # The MySQL server
 25 [mysqld]
 26 port = 3306
 27 socket = /var/lib/mysql/mysql.sock

 33 read_buffer_size = 2M
 34 read_rnd_buffer_size = 8M
 35 myisam_sort_buffer_size = 64M
 36 thread_cache_size = 8

port = 3306 就直接加上？！我试试，，还有我那个my.cnf文件里面所有内容：
datadir=/var/lib/mysql

user=mysql
