ここに記載されていることをそのまま作業すれば何の問題も無かったのに、ここにたどり着くまでネット徘徊で時間を浪費してました”^^;

Red Hat Enterprise Linux 7,CentOS 7はまずここを確認ですね。

1. vnc server install
Shell

2. config file copy

今回はユーザごとの利用を想定して設定ファイルを作成します。

Shell

[root@host01 ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver-matsuoka@.service

1	[root@host01 ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver-matsuoka@.service

3. config file edit

config fileにUserIDを設定します。
【default】

[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i" PIDFile=/home/<USER>/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.target

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target   [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i" PIDFile=/home/<USER>/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'   [Install] WantedBy=multi-user.target

<USER>をUserIDに変更します。

[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/sbin/runuser -l matsuoka -c "/usr/bin/vncserver %i" PIDFile=/home/matsuoka/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.target

4. 設定の反映
Shell

[root@host01 ~]# systemctl daemon-reload

1	[root@host01 ~]# systemctl daemon-reload

実はこのコマンドを実行する前に確認したらすでに反映されていたのですが、念の為にってことでガイドにそって実行しておきました。

Shell

[root@host01 ~]# systemctl list-unit-files | grep vnc vncserver-matsuoka@.service disabled

1 2	[root@host01 ~]# systemctl list-unit-files | grep vnc vncserver-matsuoka@.service                 disabled

5. パスワード設定

ユーザになってパスワードを設定します。
実際にはユーザ自身に設定してもらうことになると思いますが。

Shell

[root@host01 ~]# su - matsuoka Last login: Mon Feb 22 15:33:29 JST 2016 on tty1 [matsuoka@host01 ~]$ vncpasswd Password: Verify: [matsuoka@host01 ~]$ exit

1 2 3 4 5 6

[root@host01 ~]# su - matsuoka Last login: Mon Feb 22 15:33:29 JST 2016 on tty1 [matsuoka@host01 ~]$ vncpasswd Password: Verify: [matsuoka@host01 ~]$ exit

パスワードファイルは下記に作成されます。

Shell

[root@host01 ~]# ll ~matsuoka/.vnc/passwd -rw-------. 1 matsuoka matsuoka 8 Feb 22 16:57 /home/matsuoka/.vnc/passwd [root@host01 ~]# file ~matsuoka/.vnc/passwd /home/matsuoka/.vnc/passwd: data

1 2 3 4

[root@host01 ~]# ll ~matsuoka/.vnc/passwd -rw-------. 1 matsuoka matsuoka 8 Feb 22 16:57 /home/matsuoka/.vnc/passwd [root@host01 ~]# file ~matsuoka/.vnc/passwd /home/matsuoka/.vnc/passwd: data

6. vncサーバ起動

今回はディスプレイ:1で起動します。接続ポートは5901になります。

[root@host01 ~]# systemctl start vncserver-matsuoka@:1.service [root@host01 ~]# systemctl status vncserver-matsuoka@:1.service * vncserver-matsuoka@:1.service - Remote desktop service (VNC) Loaded: loaded (/etc/systemd/system/vncserver-matsuoka@.service; disabled; vendor preset: disabled) Active: active (running) since Mon 2016-02-22 17:00:08 JST; 12s ago Process: 16360 ExecStart=/usr/sbin/runuser -l matsuoka -c /usr/bin/vncserver %i (code=exited, status=0/SU CCESS) Process: 16357 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, st atus=0/SUCCESS) Main PID: 16385 (Xvnc) CGroup: /system.slice/system-vncserver\x2dmatsuoka.slice/vncserver-matsuoka@:1.service > 16385 /usr/bin/Xvnc :1 -desktop host01.rootlinks.net:1 (matsuoka) -auth /home/matsuoka/.Xau...

1 2 3 4 5 6 7 8 9 10 11 12 13

[root@host01 ~]# systemctl start vncserver-matsuoka@:1.service [root@host01 ~]# systemctl status vncserver-matsuoka@:1.service * vncserver-matsuoka@:1.service - Remote desktop service (VNC)    Loaded: loaded (/etc/systemd/system/vncserver-matsuoka@.service; disabled; vendor preset: disabled)    Active: active (running) since Mon 2016-02-22 17:00:08 JST; 12s ago   Process: 16360 ExecStart=/usr/sbin/runuser -l matsuoka -c /usr/bin/vncserver %i (code=exited, status=0/SU               CCESS)   Process: 16357 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, st               atus=0/SUCCESS) Main PID: 16385 (Xvnc)    CGroup: /system.slice/system-vncserver\x2dmatsuoka.slice/vncserver-matsuoka@:1.service            > 16385 /usr/bin/Xvnc :1 -desktop host01.rootlinks.net:1 (matsuoka) -auth /home/matsuoka/.Xau...   Feb 22 17:00:05 host01.rootlinks.net systemd[1]: Starting Remote desktop service (VNC)... Feb 22 17:00:08 host01.rootlinks.net systemd[1]: Started Remote desktop service (VNC).

7. 自動起動設定

サーバ起動時に自動起動していつでもvnc接続が出来るようにします。

Shell

[root@host01 ~]# systemctl enable vncserver-matsuoka@:1.service

1	[root@host01 ~]# systemctl enable vncserver-matsuoka@:1.service

これで端末からvnc接続できるようになったはずです。
次回は実際に接続してみます。

ちなみにvncサーバの停止は

自動起動の停止は

になります。
