WSL2 Ubuntu 22でapache2が起動しているのにlocalhostにアクセスできなかった

Last updated at 2022-08-29Posted at 2022-08-29

結局wslの再起動で解決したが、以下その経過ログ

作業ログ

service自体は上手く立っているようだ

$ service apache2 status
 * apache2 is running
$ curl -I localhost
curl: (7) Couldn't connect to server
$ curl -I 0.0.0.0
curl: (7) Couldn't connect to server

service apache2 stopやstartで再起動などを繰り返してみた、error_logには起動の旨書かれている

$ tail -f /var/log/apache2/error.log

lsofでhttp(:80)ポート確認、問題なく確保できている

$ sudo lsof -i:80
COMMAND PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

apache2 384 www-data    3u  IPv6  17054      0t0  TCP *:http (LISTEN)

ネットワークを見てみる、wslはifconfigではなくipで見る　見たところinet設定が無い

$ ip address show
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 72:e4:06:4e:49:0e brd ff:ff:ff:ff:ff:ff
3: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 4a:5d:49:a6:df:ab brd ff:ff:ff:ff:ff:ff
4: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
    link/sit 0.0.0.0 brd 0.0.0.0
5: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 00:15:5d:10:0f:49 brd ff:ff:ff:ff:ff:ff

wsl再起動する、Win側のコマンドプロンプトで以下実行

C:\> wsl --shutdown

起動はubuntuターミナルを起動すればOK、ネットワークを見るとちゃんとloopbackのinetが復活している

$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 0e:c6:f7:f3:01:85 brd ff:ff:ff:ff:ff:ff
3: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000

4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:10:06:fb brd ff:ff:ff:ff:ff:ff
    inet 172.28.230.27/20 brd 172.28.239.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fe10:6fb/64 scope link
       valid_lft forever preferred_lft forever
5: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
    link/sit 0.0.0.0 brd 0.0.0.0

service apache2を再起動してcurlできるようになった

$ sudo service apache2 start
 * Starting Apache httpd web server apache2
$ curl http://localhost
