Problem with wifi access point

Question

I have a problem with wifi access point on Raspberry 3B+.

/etc/hostapd/hostapd.conf:

interface=wlan0
driver=nl80211
ssid=Rpi_ap
hw_mode=g
channel=7
ieee80211n=1
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=1234567890
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
logger_syslog=-1
ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]

/etc/dnsmasq.conf

interface=wlan0
dhcp-range=192.168.5.100,192.168.5.200,255.255.255.0,24h

pi@raspberrypi:~ $ ifconfig wlan0

wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
    inet 192.168.5.1  netmask 255.255.255.0  broadcast 192.168.5.255
    inet6 fe80::ba27:ebff:fe5c:49c7  prefixlen 64  scopeid 0x20<link>

    TX packets 1101  bytes 146273 (142.8 KiB)
    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

i do

sudo ifconfig wlan0 192.168.5.1 netmask 255.255.255.0 broadcast 192.168.5.255
sudo systemctl start dnsmasq.service
sudo hostapd -d /etc/hostapd/hostapd.conf

output here https://pastebin.com/EAxFFeA4

As result i have no access point. What i do wrong? What could be the reason?

UPD:

I found a mistake in cat /etc/default/hostapd (thanks @M. Rostami) and fixed it. But acceess point didn't appear.

/etc/default/hostap:

DAEMON_CONF="/etc/hostapd/hostapd.conf"

pi@raspberrypi:~ $ sudo service hostapd status

UPD2:

New data. if I set static ip address for wlan0 in /etc/networks/interfaces and then reboot i have access point after boot. If set static ip address by command "ifconfig wlan0 192.168.5.1 netmask 255.255.255.0 broadcast 192.168.5.255" i have no access point after "sudo systemctl start dnsmasq.service" and "sudo systemctl start hostapd.service".

Answer 1

Try this before running your access point :

sudo kill -9 $(pidof hostapd dnsmasq dhclient wpa_supplicant)

or before your commands try only

echo $(pidof hostapd dnsmasq dhclient wpa_supplicant) 

for showing any already running process able to interfere.

The echo command must return nothing if all is good for starting your AP
