嗨，我尝试在 ubuntu 12.04 中配置清漆 4
这是我的清漆配置
sudo 更多 /etc/default/varnish
# Configuration file for Varnish Cache.
#
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES and $MEMLOCK
# to be set from this shell script fragment.
#
# Note: If systemd is installed, this file is obsolete and ignored. You will
# need to copy /lib/systemd/system/varnish.service to /etc/systemd/system/ and
# edit that file.
# Should we start varnishd at boot? Set to "no" to disable.
START=yes
# Maximum number of open files (for ulimit -n)
NFILES=131072
# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory. If you increase log size,
# you need to increase this number as well
MEMLOCK=82000
