PHP企业级应用缓存技术详解
| ator，apc，phpa，xcache等等。
MySQL缓存 这也算非代码级的，经典的数据库就是用的这种方式，看下面的运行时间，0.09xxx之类的。
[client] …… default-character-set=gbk default-storage-engine=MYISAM max_connections=600 max_connect_errors=500 back_log=200 interactive_timeout=7200 query_cache_size=64M …… table_cache=512 …… myisam_max_sort_file_size=100G myisam_max_extra_sort_file_size=100G myisam_sort_buffer_size=128M key_buffer_size=1024M read_buffer_size=512M …… thread_concurrency=8
基于反向代理的Web缓存 如Nginx，SQUID，mod_PRoxy(apache2以上又分为mod_proxy和mod_cache) NGINX的例子：
#user nobody; worker_processes 4; error_log logs/error.log crit; pid logs/nginx.pid; worker_rlimit_nofile 10240; events { use epoll; worker_connections 51200; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; tcp_nodelay on; # server pool upstream bspfrontsvr { server 10.10.10.224:80 weight=1; server 10.10.10.221:80 weight=1; } upstream bspimgsvr { server 10.10.10.201:80 weight=1; } upstream bspstylesvr { server 10.10.10.202:80 weight=1; } upstream bsphelpsvr { server 10.10.10.204:80 weight=1; } upstream bspwsisvr { server 10.10.10.203:80 weight=1; } upstream bspadminsvr { server 10.10.10.222:80 weight=1; } upstream bspbuyersvr { server 10.10.10.223:80 weight=1; } upstream bspsellersvr { server 10.10.10.225:80 weight=1; } upstream bsploginsvr { server 10.10.10.220:443 weight=1; } upstream bspregistersvr { server 10.10.10.220:80 weight=1; } log_format test_com ‘$remote_addr – $remote_user [$time_local] “$request” ‘ ‘$status $body_bytes_sent “$http_referer” “$http_user_agent” ‘; #——————————————————————– #img.test.com server { listen 10.10.10.230:80; server_name img.test.com; location / { proxy_pass http://bspimgsvr; include proxy_setting.conf; } access_log logs/img.log test_com; } #style.test.com server { listen 10.10.10.230:80; server_name style.test.com; location / { proxy_pass http://bspstylesvr; include proxy_setting.conf; } access_log logs/style.log test_com; } #help.test.com server { listen 10.10.10.230:80; server_name help.test.com; location / { proxy |
