我在使用xcache的时候, 跨进程的cache 一直读取不到, 好像并未有缓存到共享内存中
配置如下:
<code>XCache XCache Version => 3.1.0 xcache.coredump_directory => no value => no value xcache.disable_on_crash => Off => Off xcache.experimental => Off => Off xcache.test => Off => Off XCache Cacher XCache Cacher Module => enabled xcache.admin.enable_auth => On => On xcache.allocator => bestfit => bestfit xcache.cacher => On => On xcache.count => 1 => 1 xcache.gc_interval => 0 => 0 xcache.mmap_path => /tmp/zero => /tmp/zero xcache.readonly_protection => Off => Off xcache.shm_scheme => mmap => mmap xcache.size => 60M => 60M xcache.slots => 8K => 8K xcache.stat => On => On xcache.ttl => 0 => 0 xcache.var_allocator => bestfit => bestfit xcache.var_count => 1 => 1 xcache.var_gc_interval => 300 => 300 xcache.var_maxttl => 0 => 0 xcache.var_namespace => no value => no value xcache.var_namespace_mode => 0 => 0 xcache.var_size => 4M => 4M xcache.var_slots => 8K => 8K xcache.var_ttl => 0 => 0 XCache Coverager XCache Coverager Module => enabled xcache.coveragedump_directory => no value => no value xcache.coverager => Off => Off xcache.coverager_autostart => On => On XCache Optimizer XCache Optimizer Module => enabled xcache.optimizer => Off => Off </code>
我的验证方法是:
<code>if (!xcache_isset("count")) {
var_dump("not set");
xcache_set("count", 1);
}
var_dump(xcache_get("count"));
</code>一直都输出
<code>string(7) "not set" int(1) </code>
当前进程中是可以获取到的缓存, 但新开的进程就是获取不到, 求解

找到答案了,我的验证方式是以php脚本的方式运行的, 而脚本在运行完成后就释放所占用的内存了, 所以保存在共享内存中的xcache被释放了, 所以导致每次进程之间是没有共享的. 而如果是以php-fpm 方式处理的, 因为fpm进程一个服务进程, 不会运行结束, 所以xcache 在这种时候是多进程共享缓存的
