After you install Alpine, you may be wondering how do I figure out the fastest mirror again?
Contents of /home/user/fastestmirror
data=""
for s in $(wget -qO- http://rsync.alpinelinux.org/alpine/MIRRORS.txt); do
t=$(time -f "%E" wget -q $s/MIRRORS.txt -O /dev/null 2>&1)
echo "$s was $t"
data="$data$t $s\n"
done
echo "===RESULTS==="
echo -e $data | sort
This is more advanced implementation.
Contents of /etc/apk/fastest-mirror
#!/bin/sh
get_hostname_url() {
local n=${1#*://}
echo ${n%%/*}
}
time_cmd() {
local proc=$(cut -d ' ' -f1 /proc/uptime)
local start="$(echo $proc | cut -d . -f1)$(echo $proc | cut -d . -f2)"
$@ >/dev/null 2>&1 || return
proc=$(cut -d ' ' -f1 /proc/uptime)
local end="$(echo $proc | cut -d . -f1)$(echo $proc | cut -d . -f2)"
echo $(( $end - $start ))
}
DATA=""
MIRRORS=$(wget -qO- "http://rsync.alpinelinux.org/alpine/MIRRORS.txt")
DST=/etc/apk/mirrors.txt
#find best
for URL in $MIRRORS; do
TIME=$(time_cmd wget -T 1 -t 1 -q ${URL%/} -O /dev/null)
if [ -n "$TIME" ]; then
echo "$(get_hostname_url $URL) was $TIME"
DATA="$DATA$TIME $URL\n"
fi
done
echo $DATA | sort -n | tail -n +2 > $DST
[ $? = 0 ] && echo file $DST created
BEST=$(head -n1 $DST | cut -d ' ' -f2)
echo "Best mirror is: $BEST"
