php5.3.28安装加速缓存xcache

刚刚把eAccelerator换成APC也坚持不了多久，运行了一天就完蛋了，php502错误，php-fpm卡住罢工！当php-fpm进程异常退出的时候其他进程无法获取apc的互斥锁。导致死锁。这次继续搜索apc资料，有人提到惠新宸（apc维护者之一）他建议不要再使用apc，建议换成opcache，php5.3用不了哈。 这次试试国产xcache wget -c http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz tar zxvf xcache-3.2.0.tar.gz cd xcache-3.2.0 /usr/local/php/bin/phpize ./configure --enable-xcache --enable-xcache-coverager --enable-xcache-optimizer --with-php-config=/usr/local/php/bin/php-config make make install 安装成功后，在php.ini配置文件尾部里面加入以下 xcache.admin.pass这里的管理密码需要32位的，随便找个网站生成下。 xcache.count 这里是cpu几核 ;xcache [xcache-common] extension = xcache.so [xcache.admin] xcache.admin.enable_auth = On xcache.admin.user = "admin" ;run: echo -n "yourpassword" |md5sum |awk '{print $1}' to get md5 password xcache.admin.pass = "c8e1118e1e8429ebabc79b3d910cb7a0" [xcache] xcache.shm_scheme =        "mmap" xcache.size  =               128M ; set to cpu count (cat /proc/cpuinfo |grep -c processor) xcache.count =                 8 xcache.slots =                8K xcache.ttl   =                 0 xcache.gc_interval =           0 xcache.var_size  =            4M xcache.var_count =             1 xcache.var_slots =            8K xcache.var_ttl   =             0 xcache.var_maxttl   =          0 xcache.var_gc_interval =     300 xcache.readonly_protection = Off ; for *nix, xcache.mmap_path is a file path, not directory. (auto create/overwrite) ; Use something like "/tmp/xcache" instead of "/dev/*" if you want to turn on ReadonlyProtection ; different process group of php won't share the same /tmp/xcache xcache.mmap_path =    "/dev/zero" xcache.coredump_directory =   "" xcache.experimental =        Off xcache.cacher =               On xcache.stat   =               On xcache.optimizer =           Off [xcache.coverager] ; enabling this feature will impact performance ; enable only if xcache.coverager == On && xcache.coveragedump_directory == "non-empty-value" ; enable coverage data collecting and xcache_coverager_start/stop/get/clean() functions xcache.coverager =          Off xcache.coveragedump_directory = "" ;xcache end 重启php即可，输出echo phpinfo(); 查看是否成功！ 这时候需要运行管理它，在xcache-3.2.0目录下的htdocs管理代码目录拷贝到可以运行的虚拟主机下，直接运行即可。 其它配置的详细解说看xcache.lighttpd.net 有问题请留言^_^
