# URLロリ
クッソ小さいURL短縮作成ソフトだわ〜♡

## インストールする方法

### 従属ソフト

* Go 1.19以上
* nginx又はOpenBSDのrelayd
* 良いOS (GNU/Linux、OpenBSD、又はFreeBSD)

## インストールする方法

### 全部（opendoasを使わなければ、sudoをご利用、又はopendoasをインストールして下さい）

```sh
make
doas make install
```

### OpenBSD

```sh
nvim /etc/rc.d/urloli
```

```
#!/bin/ksh

daemon="/usr/local/bin/urloli -s"

. /etc/rc.d/rc.subr

rc_bg=YES
rc_reload=NO

rc_cmd $1
```

```sh
chmod +x /etc/rc.d/urloli
rcctl enable urloli
rcctl start urloli
```

### FreeBSD

```sh
nvim /usr/local/etc/rc.d/urloli
```

```
#!/bin/sh

# PROVIDE: urloli
# REQUIRE: NETWORKING SYSLOG
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf to enable urloli:
#
#urloli_enable="YES"

. /etc/rc.subr

name="urloli"
rcvar="urloli_enable"

load_rc_config $name

: ${urloli_enable:="NO"}
: ${urloli_facility:="daemon"}
: ${urloli_priority:="debug"}

command="/usr/local/bin/${name}"
procname="/usr/local/bin/${name}"

pidfile="/var/run/${name}.pid"

start_cmd="${name}_start"

urloli_start() {
  for d in /var/db/urloli /var/log/urloli; do
    if [ ! -e "$d" ]; then
      mkdir "$d"
    fi
  done
  /usr/sbin/daemon -S -l ${urloli_facility} -s ${urloli_priority} -T ${name} \
    -p ${pidfile} \
    /usr/bin/env -i \
    "PATH=/usr/local/bin:${PATH}" \
    $command
}

run_rc_command "$1"
```

```sh
sysrc urloli_enable=YES
service start urloli
```

### Crux

```sh
nvim /etc/rc.d/urloli
```

```
#!/bin/sh
#
# /etc/rc.d/urloli: start/stop the urloli daemon
#

SSD=/sbin/start-stop-daemon

  $SSD --status --pidfile $PID
  case $? in
  0) echo "$PROG は実行中。pid $(cat $PID)" ;;
  1) echo "$PROG は実行していませんが、pidファイルは「 $PID 」として存在しそう" ;;
  3) echo "$PROG は停止中" ;;
  4) echo "状況不明" ;;
