Me k\u00f5ik teame selles postituses<\/a> varem, et saame kasutada PHP- s shell_exec<\/strong> v\u00f5i exec<\/strong>, et saada serverisse v\u00e4lise programmi v\u00e4ljund. Ilmselgelt saame serveri oleku saamiseks k\u00e4ivitada linux k\u00e4su uptime<\/strong>, mis annab midagi sellist (v\u00f5i kui seda blogi alla kerida, siis selle lehe l\u00f5pust leiad peaaegu reaalajas olekuuuenduse, st mida uuendatakse iga kord 5 minutit):<\/p>\n

\u00a010:25:01 up 31 days, 15:17, \u00a00 users, \u00a0load average: 0.01, 0.09, 0.12<\/code><\/pre>\n
Nendel p\u00f5hjustel ei ole aga soovitatav k\u00e4ivitada otse uptime<\/strong> k\u00e4sku kasutades shell_exec<\/strong> v\u00f5i exec .<\/strong>
\nEsiteks v\u00f5ivad veebimajutusettev\u00f5tted keelata shell_exec<\/strong> ja exec<\/strong> (niipalju kui mina tean), peamiselt jagatud hostidel turvalisuse huvides. Fasthosts keelab selle, kuid Godday seevastu ei keela seda kasutamist. Teiseks peetakse nende kahe k\u00e4su reaalajas k\u00e4itamist PHP-skriptides ebaefektiivseks ja aegan\u00f5udvaks (CPU).<\/p>\n
\u00d5ige\/soovitatav viis sellise teabe hankimiseks on j\u00e4rgmine: Esiteks loo crontab<\/a>, mis t\u00f6\u00f6tab teatud ajavahemike j\u00e4rel, nt iga 2 minuti j\u00e4rel serveris, kasutades crontab -e<\/strong> saad t\u00f6id redigeerida oma lemmiktekstiredaktoriga, n\u00e4iteks nagu nano<\/strong> v\u00f5i vim<\/strong>.<\/p>\n
*\/2 * * * * \/usr\/bin\/uptime > $HOME\/htdocs\/uptime.txt<\/code><\/pre>\n
Seega iga 2 minuti j\u00e4rel (eemaldage \/2 iga minuti kohta) uuendatakse faili uptime.txt ja see asetatakse avalikku HTTP-kausta.<\/strong> Seega saate selliste andmete saamiseks kasutada j\u00e4rgmist PHP-skripti.<\/p>\n
$uptime = file_get_contents('<a class=\"vglnk\" target=\"_blank\" href=\"http:\/\/'.$_SERVER['SERVER_NAME'].'\/uptime.txt\" rel=\"nofollow\"><span>http<\/span><span>:\/\/'.$_<\/span><span>SERVER<\/span><span>['<\/span><span>SERVER<\/span><span>_<\/span><span>NAME<\/span><span>'].'\/<\/span><span>uptime<\/span><span>.<\/span><span>txt<\/span><\/a>');\nif ($uptime) {\n\u00a0 echo $uptime;\n}<\/code><\/pre>\n
K\u00f5lab \u00fcsna lihtsalt, eks? See annab teile suhteliselt t\u00e4pse t\u00f6\u00f6aja oleku ja v\u00f5ite selle teabe panna WordPressi ajaveebi jalusesse.php<\/strong> (n\u00e4iteks kerige lehe l\u00f5puni).<\/p>\n
V\u00f5ite kasutada ka serveri muutujat DOCUMENT_ROOT<\/strong>, mis esindab veebisaidi juurkataloogi. Seega veenduge, et fail uptime.txt<\/strong> asub veebisaidi juurkataloogis.<\/p>\n
$uptime = '';\n$uptimefile = $_SERVER['DOCUMENT_ROOT']. '\/uptime.txt';\nif (is_file($uptimefile)) {\n\u00a0 \u00a0 $uptime = @file_get_contents($uptimefile);\n} \u00a0<\/code><\/pre>\n
