Start varnish:

# Ulimit-shn51200

# Useradd-s/sbin/nologin www

#/Opt/varnish/sbin/varnishd-u www-g www-f/opt/varnish/etc/varnish/test. vcl-a 192.168.2.4: 80-s file,/data/varnish_cache/varnish_cache.data, 1G-w 1024,5100, 10-t 3600-T 192.168.2.4: 3500

Parameter:-u used for running

-G

-F varnish configuration file

-A: bind the IP address and port

-S varnish cache file location and size

-W minimum, maximum thread and timeout

-T varnish management Port, mainly used to clear the cache

-S file,/data/varnish_cache/varnish_cache.data, 1 GB cache Directory. the 32-bit system cannot exceed 2 GB. we recommend that you use a 64-bit system and a faster speed, changing this directory to the memory cache will be faster, and the larger the memory, the better.

Stop varnish:

# Pkill varnishd
