1. first of all, show me your wireless network:

>> iwlist scan

wlan0     Scan completed :
          Cell 01 - Address: 14:CF:92:91:F1:2E
                    ESSID:"my12345"
                    Protocol:IEEE 802.11bgn
                    Mode:Master
                    Frequency:2.437 GHz (Channel 6)
                    Encryption key:on
                    Bit Rates:150 Mb/s
                    Extra:wpa_ie=dd160050f20101000050f20401000050f20401000050f202
                    IE: WPA Version 1
                        Group Cipher : CCMP
                        Pairwise Ciphers (1) : CCMP
                        Authentication Suites (1) : PSK
                    Extra:rsn_ie=30140100000fac040100000fac040100000fac020000
                    IE: IEEE 802.11i/WPA2 Version 1
                        Group Cipher : CCMP
                        Pairwise Ciphers (1) : CCMP
                        Authentication Suites (1) : PSK
                    Quality=100/100 Signal level=100/100

2. then, configure your conf file of wpa_suppliant

>> cat /etc/wpa_suppliant/wpa_suppliant.conf

     ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
        ssid="my12345"
        proto=WPA2
        key_mgmt=WPA-PSK
        pairwise=CCMP
        group=CCMP
        psk=c0d128a54dc2b0d29cc058204088440efd2fa168a2d96594f5736f9f3b34f6a9
}
//NOTE: psk is created by:

// wpawpa_passphrase my12345 my_password.

3. check this file:

cat /etc/sysconfig/wpa_supplicant
# Use the flag "-i" before each of your interfaces, like so:
# INTERFACES="-i eth1 -i wlan0"
INTERFACES="-i wlan0"

# Use the flag "-D" before each driver, like so:
# DRIVERS="-D wext"
DRIVERS="-D wext"

# Other arguments
# -u Enable the D-Bus interface (required for use with NetworkManager)
# -f Log to /var/log/wpa_supplicant.log
OTHER_ARGS="-u -f /var/log/wpa_supplicant.log"

4. things are ready, use:

>>service wpa_suppliant start

5. get the ip address

>> dhclient
