Q. How do I install and configure xcache under FreeBSD operating systems for Apache, lighttpd or ngnix web server?
A. XCache is a fast, stable php opcode cacher that has been tested and now running on production server under high load.
FreeBSD install xcache
xcache can be installed using FreeBSD ports system or pkg_add command itself. First, update ports tree:
# portsnap fetch update
Install xcache, enter:
# cd /usr/ports/www/xcache
# make install clean
Enable xache
To enable xcahce copy the /usr/local/share/examples/xcache/xcache.ini config file into /usr/local/etc/php/ and modify it to suit your needs, enter:
# cp /usr/local/share/examples/xcache/xcache.ini /usr/local/etc/php/
# cd /usr/local/etc/php/
# vi xcache.ini
Set xcache.size and other parameters as per your requirements. Here is my sample xcache for FreeBSD 7 with quad core CPU and 4GiG RAM:
[xcache-common] extension = xcache.so [xcache.admin] xcache.admin.enable_auth = On xcache.admin.user = "admin" ; xcache.admin.pass = md5($your_password) xcache.admin.pass = "" [xcache] ; ini only settings, all the values here is default unless explained ; select low level shm/allocator scheme implemenation xcache.shm_scheme = "mmap" ; to disable: xcache.size=0 ; to enable : xcache.size=64M etc (any size > 0) and your system mmap allows xcache.size = 512M ; set to cpu count (cat /proc/cpuinfo |grep -c processor) xcache.count = 4 ; just a hash hints, you can always store count(items) > slots xcache.slots = 8K ; ttl of the cache item, 0=forever xcache.ttl = 0 ; interval of gc scanning expired items, 0=no scan, other values is in seconds xcache.gc_interval = 0 ; same as aboves but for variable cache xcache.var_size = 128M xcache.var_count = 1 xcache.var_slots = 8K ; default ttl xcache.var_ttl = 0 xcache.var_maxttl = 0 xcache.var_gc_interval = 300 xcache.test = Off ; N/A for /dev/zero xcache.readonly_protection = Off ; for *nix, xcache.mmap_path is a file path, not directory. ; Use something like "/tmp/xcache" if you want to turn on ReadonlyProtection ; 2 group of php won't share the same /tmp/xcache ; for win32, xcache.mmap_path=anonymous map name, not file path xcache.mmap_path = "/dev/zero" ; leave it blank(disabled) or "/tmp/phpcore/" ; make sure it's writable by php (without checking open_basedir) xcache.coredump_directory = "" ; per request settings xcache.cacher = On xcache.stat = On xcache.optimizer = Off [xcache.coverager] ; per request settings ; enable coverage data collecting for xcache.coveragedump_directory and xcache_coverager_start/stop/get/clean() functions (will hurt executing performance) xcache.coverager = Off ; ini only settings ; make sure it's readable (care open_basedir) by coverage viewer script ; requires xcache.coverager=On xcache.coveragedump_directory = ""
Restart web server
Type the following command to restart apache22:
# /usr/local/etc/rc.d/apache22 restart
If you are using nginx web server, enter:
# /usr/local/etc/rc.d/nginx restart
If you are using lighttpd web server, enter:
# /usr/local/etc/rc.d/lighttpd restart
