Владислав: сейчас сделаем. Завтра проверю уже ночь народу мало на сайте. Как я понял подключаться я буду так $bd_host = "192.168.1.1:".rand(3306,3308);
Владислав: во по поводу увелечения port range:
/proc/sys/net/ipv4/tcp_tw_reuse
1
root@mysql ~ # sysctl net.ipv4.ip_local_port_range
net.ipv4.ip_local_port_range = 1024 65535
Но ещё советуют на mysql-форуме вдобавок:
Сделать, чтобы порты закрывались сразу по завершению, а не ждали таймаут
и Не забудьте также, что если клиентских портов не хватит, можно сделать чтобы сервер слушал порты 3306, 3307, 3308 и.т.д. и чередовать в клиенте (можно выбирать случайно).
Вы правы. Переход планируется но немного попозже. Насчёт кеша fcgi через nginx не уверен что он будет лучше нежели Xcache. Отклик у нас 166мс. Про нагрузку не паримся как вы видите по htop обоих серверов. Похоже вы мой пост не до конца прочитали=(
mysql сервак:
root@mysql ~ # netstat -n
