任何人都可以帮我解决如何增加 Debian 中弹性搜索的最大打开文件数吗?另外关于如何增加它的内存限制?以及如何检查是否应用了内存限制?我有一个文件“/etc/init.d/elasticsearch”,其设置如下:
`#! /bin/sh`
`### BEGIN INIT INFO`
`# Provides: elasticsearch`
`# Required-Start: $all`
`# Required-Stop: $all`
`# Default-Start: 2 3 4 5`
`# Default-Stop: 0 1 6`
`# Short-Description: Starts elasticsearch`
`# Description: Starts elasticsearch using start-stop-daemon`
`### END INIT INFO`
`ES_HOME=/usr/local/elasticsearch`
`ES_MIN_MEM=256m`
`ES_MAX_MEM=2g`
`DAEMON=$ES_HOME/bin/elasticsearch`
`NAME=elasticsearch`
`DESC=elasticsearch`
`PID_FILE=/var/run/$NAME.pid`
`LOG_DIR=/var/log/$NAME`
`DATA_DIR=/var/lib/$NAME`
`WORK_DIR=/tmp/$NAME`
`CONFIG_FILE=/etc/$NAME/elasticsearch.yml`
`DAEMON_OPTS="-p $PID_FILE -Des.config=$CONFIG_FILE -Des.path.home=$ES_HOME -Des.path.logs=$LOG_DIR -Des.path.data=$DATA_DIR -Des.path.work=$WORK_DIR"`
`test -x $DAEMON || exit 0
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
mkdir -p $LOG_DIR $DATA_DIR $WORK_DIR
if start-stop-daemon --start --pidfile $PID_FILE --startas $DAEMON -- $DAEMON_OPTS
then
echo "started."
else
echo "failed."
fi
;;
stop)
echo -n "Stopping $DESC: "
if start-stop-daemon --stop --pidfile $PID_FILE
then
echo "stopped."
else
echo "failed."
fi
;;
restart|force-reload)
${0} stop
sleep 0.5
${0} start
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart|force-reload}" >&2
exit 1
;;
esac
exit 0
任何有关这些的帮助将不胜感激.. 提前致谢..
